Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of part assembly, and in particular to an auxiliary installation device. BACKGROUND

[0002] In the prior art, the manufacturing process of the pantograph slide plate generally includes bending, punching, bonding, heat treatment, and assembly. The pantograph slide plate generally includes a slide plate body and a plurality of spare parts to be installed, such as a bracket, an air source, and a flow guide plate. The plurality of spare parts are generally installed at the installation holes provided on the slide plate body, and the adjacent spare parts and the symmetrically arranged spare parts have a preset spacing. In the actual assembly process, the through holes on the spare parts to be installed need to be one-to-one corresponding to the installation holes provided on the slide plate body (i.e., aligned installation).

[0003] At present, the manual free assembly method is generally used according to the positions of the installation holes. Specifically, the through holes of the spare parts to be installed are aligned with the installation holes, and then the fasteners such as bolts are used to penetrate the through holes and the installation holes to install the spare parts on the slide plate body.

[0004] However, if the positions of one or more installation holes provided on the slide plate body deviate, the actual distance between the spare parts will be inconsistent with the preset spacing, thereby affecting the quality of the pantograph slide plate and increasing the later return rate. SUMMARY

[0005] The present application aims to provide an auxiliary installation device for avoiding the installation of spare parts on a slide plate body with unqualified installation hole positions, improving the quality of the pantograph slide plate, and reducing the later return rate.

[0006] To achieve the above-mentioned purpose, the present application provides an auxiliary installation device. The auxiliary installation device comprises a base frame, a bracket installation structure, an air source installation structure, and a flow guide plate installation structure. The base frame has a containing space and a bearing surface, the bracket installation structure is arranged on the base frame, and is used to make the center axis of the bracket installation hole provided on the bracket and the center axis of the first installation hole provided on the workpiece template collinear, so as to assist in installing the bracket on the workpiece template. The air source installation structure is arranged on the bearing surface, and is used to make the center axis of the air source and the center axis of the second installation hole provided on the workpiece template collinear, so as to assist in installing the air source on the workpiece template. The flow guide plate installation structure is arranged on the bearing surface, and is used to make the center axis of the flow guide plate installation hole provided on the flow guide plate and the center axis of the third installation hole provided on the workpiece template collinear, so as to assist in installing the flow guide plate on the workpiece template. When the auxiliary installation device is in a working state, the center axis of the bracket installation hole and the center axis of the first installation hole, the center axis of the air source and the center axis of the second installation hole, and the center axis of the flow guide plate installation hole and the center axis of the third installation hole are collinear at the same time.

[0007] The workpiece template can be a slide plate body or other components. The following description is based on the slide plate body, and it should be understood that the following description is only for understanding and is not used for specific definition. The size of the workpiece template is consistent with the size of the slide plate body to be installed. Compared with the prior art, in the auxiliary installation device provided by the application, when actually assembling, only the slide plate body to be installed is placed on the bearing surface, and the installation surface of the installation spare part is ensured to face the bracket mounting structure, the gas source mounting structure and the guide plate mounting structure. Since the bracket mounting structure can make the center axis of the bracket mounting hole on the bracket and the center axis of the first mounting hole on the workpiece template be collinear. Therefore, if the bracket mounting hole on the bracket placed on the bracket mounting structure cannot be aligned with the first mounting hole, it indicates that the position of the slide plate body relative to the bracket is offset or the position of the first mounting hole on the slide plate body is deviated. Further, since the gas source mounting structure is used to make the center axis of the gas source and the center axis of the second mounting hole on the workpiece template be collinear, the gas source is installed on the workpiece template. Therefore, if the gas source placed on the gas source mounting structure cannot be aligned with the second mounting hole, it indicates that the position of the slide plate body relative to the gas source is offset or the position of the second mounting hole on the slide plate body is deviated. Further, since the guide plate mounting structure is used to make the center axis of the guide plate mounting hole on the guide plate and the center axis of the third mounting hole on the workpiece template be collinear, the guide plate is installed on the workpiece template. Therefore, if the guide plate mounting hole on the guide plate placed on the guide plate mounting structure cannot be aligned with the third mounting hole, it indicates that the position of the slide plate body relative to the guide plate is offset or the position of the third mounting hole on the slide plate body is deviated. Further, since the auxiliary installation device is in a working state, the center axis of the bracket mounting hole and the center axis of the first mounting hole, the center axis of the gas source and the center axis of the second mounting hole, and the center axis of the guide plate mounting hole and the center axis of the third mounting hole are collinear at the same time. At this time, the auxiliary installation device can not only assist in installing the above-mentioned spare parts, but also detect whether the position of the mounting hole on the slide plate body is qualified.

[0008] In summary, if any one or more of the bracket, air source member or flow guide plate cannot be accurately and firmly installed on the corresponding position of the slide plate body while ensuring the position of the slide plate body relative to the auxiliary installation device, it indicates that the position of one or more installation holes opened on the slide plate body is deviated and does not meet the actual requirements. At this time, the slide plate body is not assembled to avoid affecting the quality of the pantograph slide plate and reducing the later return rate. It should be understood that during actual assembly, the bracket, air source member and flow guide plate can be placed on the corresponding positions of the auxiliary installation device first, and then it is pre-judged whether the installation positions of the bracket, air source member and flow guide plate are aligned with the installation holes on the slide plate body. If it is found that one of them is not aligned, subsequent assembly operation is not needed. Based on this, the auxiliary installation device saves time and effort and improves assembly efficiency. In addition, the number and spacing of the above-mentioned bracket installation structure, air source installation structure and flow guide plate installation structure can be set according to actual conditions, which are not specifically limited here.

[0042] In order to make the technical problems to be solved by the present application, technical solutions and beneficial effects clearer, the present application will be further described in detail below in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and not used to limit the present application.

[0044] In addition, the terms "first", "second" are only for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined with "first", "second" can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "a plurality of" is two or more, unless otherwise explicitly and specifically limited. The meaning of "several" is one or more, unless otherwise explicitly and specifically limited.

[0045] In the description of the present application, it should be understood that the terms "upper", "lower", "front", "back", "left", "right" and the like indicate the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present application.

[0046] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0047] Currently, through scientific research and development, China has achieved independent research and development and production of pantograph contact plates for high-speed trains operating at speeds of 300 km / h and below, including locomotives, urban rail transit, and EMUs. Significant breakthroughs have been made in pantograph contact plates for high-speed trains operating at speeds of 350 km / h. As the only component connecting the high-speed train to the high-voltage overhead contact line, the pantograph contact plate is located at the highest point of the train, operating at high speeds and under harsh conditions, thus requiring high quality in all assembly aspects. Therefore, ensuring the correct assembly dimensions of the high-speed train pantograph contact plate is crucial to avoid operational failures caused by non-compliant assembly dimensions.

[0048] In addition to the technical problems described in the background section, the following problems also exist in the prior art:

[0049] Due to worker negligence, it is easy for one or more of the components, such as the bracket, air supply unit, or deflector, to be installed incorrectly. In this case, even if the mounting holes on the pantograph body are in the correct positions, the assembled pantograph pantograph will still be defective, increasing the rate of return to the factory.

[0050] To address the aforementioned technical problems, embodiments of the present invention provide an auxiliary installation device. See also... Figures 1 to 5The auxiliary installation device 2 can include a base frame 20, a bracket installation structure 21, an air source installation structure 22, and a deflector plate installation structure 23. The base frame 20 has a containing space 200 and a bearing surface 201, and the bracket installation structure 21 is arranged on the base frame 20 to make the center axis of the bracket installation hole on the bracket 11 and the center axis of the first installation hole on the workpiece template be collinear to assist in installing the bracket 11 on the workpiece template. The air source installation structure 22 is arranged on the bearing surface 201 to make the center axis of the air source and the center axis of the second installation hole on the workpiece template be collinear to assist in installing the air source on the workpiece template. The deflector plate installation structure 23 is arranged on the bearing surface 201 to make the center axis of the deflector plate installation hole on the deflector plate and the center axis of the third installation hole on the workpiece template be collinear to assist in installing the deflector plate on the workpiece template. When the auxiliary installation device 2 is in a working state, the center axis of the bracket installation hole and the center axis of the first installation hole, the center axis of the air source and the center axis of the second installation hole, and the center axis of the deflector plate installation hole and the center axis of the third installation hole are collinear at the same time.

[0051] The workpiece template described above can be the slide plate body 10 or other components. The following description takes the slide plate body 10 as an example for description, and it should be understood that the following description is only for understanding and is not used for specific definition. The specification of the workpiece template described above is consistent with the specification of the slide plate body 10 to be installed.

[0052] Referring to Figures 1 to 7The auxiliary installation device 2 provided by the embodiment of the present application can be used in the actual assembly process. In the actual assembly process, the slide plate body 10 of the spare part to be installed is placed on the bearing surface 201, and the installation surface of the spare part is ensured to face the bracket installation structure 21, the gas source installation structure 22 and the guide plate installation structure 23. Since the bracket installation structure 21 can make the center axis of the bracket installation hole in the bracket 11 and the center axis of the first installation hole in the workpiece template be collinear, if the bracket installation hole in the bracket 11 placed on the bracket installation structure 21 cannot be aligned with the first installation hole, it indicates that the position of the slide plate body 10 relative to the bracket 11 is deviated or the position of the first installation hole in the slide plate body 10 is deviated. Further, since the gas source installation structure 22 is used to make the center axis of the gas source and the center axis of the second installation hole in the workpiece template be collinear, the gas source installation structure 22 can assist in installing the gas source on the workpiece template. Therefore, if the gas source placed on the gas source installation structure 22 cannot be aligned with the second installation hole, it indicates that the position of the slide plate body 10 relative to the gas source is deviated or the position of the second installation hole in the slide plate body 10 is deviated. Further, since the guide plate installation structure 23 is used to make the center axis of the guide plate installation hole in the guide plate and the center axis of the third installation hole in the workpiece template be collinear, the guide plate installation structure 23 can assist in installing the guide plate on the workpiece template. Therefore, if the guide plate installation hole in the guide plate placed on the guide plate installation structure 23 cannot be aligned with the third installation hole, it indicates that the position of the slide plate body 10 relative to the guide plate is deviated or the position of the third installation hole in the slide plate body 10 is deviated. In addition, since the bracket installation hole, the first installation hole, the gas source, the second installation hole, the guide plate installation hole and the third installation hole are collinear at the same time when the auxiliary installation device 2 is in the working state, the auxiliary installation device 2 can not only assist in installing the above-mentioned spare parts, but also detect whether the positions of the installation holes in the slide plate body 10 are qualified.

[0053] In summary, if any one or more of the bracket 11, the air supply member, or the flow guide plate cannot be accurately and firmly installed on the corresponding position of the slide plate body 10 while ensuring the correct position of the slide plate body 10 relative to the auxiliary installation device 2, it indicates that the position of one or more mounting holes opened on the slide plate body 10 is deviated and does not meet the actual requirements. At this time, the slide plate body 10 is not assembled to avoid affecting the quality of the pantograph slide plate 1 and reducing the later return rate. It should be understood that during actual assembly, the bracket 11, the air supply member, and the flow guide plate can be placed on the corresponding positions of the auxiliary installation device 2 first, and then it is preliminarily judged whether the installation positions of the bracket 11, the air supply member, and the flow guide plate are aligned with the mounting holes on the slide plate body 10. If it is found that one of them is not aligned, subsequent assembly operation is not needed. Based on this, the auxiliary installation device 2 saves time and effort and improves assembly efficiency. In addition, the number and spacing of the bracket mounting structure 21, the air supply mounting structure 22, and the flow guide plate mounting structure 23 can be set according to actual conditions, which are not specifically limited here.

[0054] Further, since the positions, spacings, and other parameters of the bracket mounting structure 21, the air supply mounting structure 22, and the flow guide plate mounting structure 23 in the auxiliary installation device 2 are strictly designed according to the size standard of the pantograph slide plate, the pantograph slide plate assembled by using the auxiliary installation device 2 has higher precision.

[0055] As a possible implementation manner, referring to Figures 1 to 10 The bracket mounting structure 21 can include a cushion block 210, a first installation assembly 211, and a jacking assembly 212.

[0056] The cushion block 210 is arranged on the bearing surface 201, and the bracket 11 is arranged on the cushion block 210. The cushion block 210 is used to raise the bracket 11, so that the center axis of the bracket mounting hole opened on the bracket 11 and the center axis of the first mounting hole are on the same horizontal plane. Based on this, the height of the cushion block 210 can be set according to the position of the bracket mounting hole on the bracket 11 and the position of the first mounting hole.

[0057] The first installation assembly 211 is arranged on the bearing surface 201, and the cushion block 210 is located between the first installation assembly 211 and the workpiece template. The first installation assembly 211 is used to make the fastener penetrate the bracket mounting hole and the first mounting hole, so that the bracket 11 is tightly connected with the workpiece template. The first installation assembly 211 is used to assist in installing the fastener, which saves time and effort and improves work efficiency. Exemplarily, the fastener can be a screw or a bolt, etc.

[0058] The jacking assembly 212 is arranged on the base frame 20 and located in the accommodating space 200. The cushion block 210 is sleeved on the jacking end of the jacking assembly 212, and the jacking end is used to penetrate the fixed support 11. At this time, the position of the support 11 relative to the auxiliary mounting device 2 and the workpiece template can be limited by using the jacking assembly 212, and the situation that the support 11 deviates from the installation position is reduced or avoided. That is, the deviation of the support mounting hole relative to the first mounting hole opened on the workpiece template is reduced or avoided, so as to ensure the accuracy and firmness of the later installation of the support 11 and the slide plate body 10. It should be understood that the jacking end of the jacking assembly penetrates the bearing surface.

[0059] As a possible implementation, see Figure 2 and Figure 3 The base frame 20 can include a main frame 202 and a bearing plate 203. The main frame 202 has an accommodating space 200 for accommodating the jacking assembly 212, and the bearing plate 203 is arranged on the main frame 202. The main frame 202 is a rectangular solid made of square steel with a size of 60 cm*40 cm, which is used to support the bearing plate 203, the support mounting structure 21, the air source mounting structure 22 and the flow guide plate mounting structure 23. The bearing plate 203 is made of cast steel and is precisely machined by machinery.

[0060] In an alternative way, see Figure 8 The first clamping groove 204 is arranged on the base frame 20, and the cushion block 210 is located between the first clamping groove 204 and the workpiece template. The first clamping groove 204 is arranged on the bearing plate 203, and the length extension direction L1 of the first clamping groove 204 is towards the cushion block 210, and the first clamping groove 204 is arranged in a spaced manner with the cushion block 210. Further, the center line E-E' of the first clamping groove 204 is perpendicular to the workpiece template. Specifically, see Figure 5 The center line E-E' of the first clamping groove 204 is perpendicular to the tangent F-F' of the arc portion of the workpiece template.

[0061] In an alternative way, see Figure 8 and Figure 9 The first mounting assembly 211 can include a first sliding block assembly 2110 and a first mounting piece 2111. The first sliding block assembly 2110 is in sliding connection with the first clamping groove 204, and the first mounting piece 2111 is arranged on the first sliding block assembly 2110. The first sliding block assembly 2110 is used to drive the first mounting piece 2111 to approach or move away from the cushion block 210, and the first mounting piece 2111 is used to make the fastener penetrate the support mounting hole and the first mounting hole, so as to connect the support 11 and the workpiece template.

[0062] Exemplarily, the first mounting assembly 211 includes two first mounting members 2111, each of which includes a bearing cover 24, a hex deep socket 25 and two bearings 26 in the prior art. The two hex deep sockets 25 of the two first mounting members 2111 correspond to the two bracket mounting holes on the bracket 11 respectively. In the embodiment of the application, the two first mounting members 2111 share the two bearing covers 24. Four bearing holes are formed in the first slider assembly 2110 in a matrix distribution, and the four bearings 26 are arranged in the four bearing holes correspondingly. Further, the bearing cover 24 is fixed on the two end faces of the first slider assembly 2110 provided with the bearings 26. Along the length extension direction L1 of the first clamping groove 204, the hex deep socket 25 penetrates through the two bearings 26 arranged oppositely. In the embodiment of the application, for the same bracket 11, the distance between the centers of the two hex deep sockets 25 is equal to the distance between the centers of the two first mounting holes formed on the workpiece template.

[0063] In an alternative way, referring to Figure 8 and Figure 9 , the first slider assembly 2110 can include a first slider 2112 and a second slider 2113. The first slider 2112 is in sliding connection with the first clamping groove 204, and the first slider 2112 is arranged spaced apart from the inner side wall of the first clamping groove 204. The second slider 2113 is arranged on the first slider 2112, and the second slider 2113 and the first slider 2112 are distributed in a stepped manner. Exemplarily, along the first direction M, the width of the second slider 2113 is smaller than the width of the first slider 2112. The first slider assembly 2110 can be integrally formed, or the first slider 2112 and the second slider 2113 can be fastened and connected by welding or bonding.

[0064] In an alternative way, referring to Figure 8 and Figure 9 , the first mounting assembly 211 can further include a first pressing block 2114. The first pressing block 2114 is arranged on the bearing surface 201 and located on the side surface of the second slider 2113. The first pressing block 2114 covers the first slider 2112, and along the height direction H1 of the first slider assembly 2110, the first pressing block 2114 is arranged spaced apart from the first slider 2112.

[0065] Exemplarily, a portion of the second slider 2113 that is not covered by the first slider 2112 is defined as a first step portion, and the first pressing block 2114 covers and is spaced apart from the first step portion (i.e., along the height direction H1 of the first slider assembly 2110, there is a gap between the first pressing block 2114 and the first step portion). At this time, not only can the smooth sliding of the first slider assembly 2110 be ensured, but also the first slider assembly 2110 can be prevented from being detached from the first clamping groove 204 during sliding, thereby ensuring the stability of the first mounting assembly 211. In the embodiment of the present application, one first pressing block 2114 is arranged on each of the left and right sides of the first slider assembly 2110. Further, the auxiliary mounting device 2 comprises two bracket mounting structures 21 that are symmetrically distributed along the center line B-B’ (the center line B-B’ is perpendicular to the length direction L3 of the bearing surface 201) of the bearing surface 201. Therefore, the base frame 20 is provided with two first clamping grooves 204 that are symmetrically distributed along the center line B-B’.

[0066] In an optional manner, the first slider 2112 is spaced apart from the inner side wall of the first clamping groove 204.

[0067] Exemplarily, along the first direction M, a certain distance is provided between the two ends of the first slider 2112 and the inner side wall of the first clamping groove 204, which can be set according to actual conditions. At this time, the first slider 2112 can be moved along the first direction M, i.e., the first slider assembly 2110 is moved along the first direction M to drive the first mounting piece 2111 arranged on the first slider assembly 2110 to move along the first direction M. Based on this, the application range of the first mounting assembly 211 can be expanded, and the application scenarios of the bracket mounting structure 21 can be increased. It should be understood that along the first direction M, a rectangular hole can be formed in the first pressing block 2114, and the bolt 27 penetrates through the rectangular hole to fasten the first pressing block 2114 to the base frame 20. Moreover, along the first direction M, the width of the bolt 27 is less than the length of the rectangular hole. At this time, the first pressing block 2114 can be moved along the first direction M while ensuring that the bolt 27 is fixed, so as to ensure that the first pressing block 2114 covers the first step portion.

[0068] In an optional manner, referring to Figure 3 and Figure 10The jacking assembly 212 can include a flange 2120, a connecting member 2121 and a driving member 2122. The flange 2120 is arranged on the base frame 20 and located in the accommodating space 200. For example, the flange 2120 is arranged on the back of the bearing surface 201. The first end (i.e. the jacking end) of the connecting member 2121 penetrates the flange 2120 and the bearing surface 201, and the cushion block 210 is sleeved on the first end of the connecting member 2121. The driving member 2122 has an extension driving end, and the driving member 2122 is arranged on the flange 2120, and the extension driving end is located in the flange 2120. The second end of the connecting member 2121 is connected with the extension driving end, and the driving member 2122 is used to drive the connecting member 2121 to ascend or descend, so as to approach or move away from the support 11. For example, the connecting member 2121 can be a mounting shaft, and the driving member 2122 can be a pneumatic cylinder, a hydraulic cylinder or an electric cylinder.

[0069] In an optional manner, referring to Figure 10 The jacking assembly can further include a linear bearing 2123.

[0070] For example, a linear bearing hole is formed on the bearing plate 203, the linear bearing 2123 is arranged in the linear bearing hole and tightly connected with the bearing plate 203, and the linear bearing 2123 is also located in the through hole of the flange 2120. The first end of the connecting member 2121 penetrates the linear bearing 2123, and the cushion block 210 is sleeved on the first end of the connecting member 2121. The linear bearing 2123 plays a guiding role and is used to limit the movement direction of the connecting member 2121.

[0071] As a possible implementation manner, referring to Figure 11 and Figure 12 The gas source mounting structure 22 can include a fixing member 220 and a second mounting member 221. The fixing member 220 is arranged on the bearing surface 201, the first end of the second mounting member 221 is arranged on the fixing member 220, and the second end of the second mounting member 221 is used to be connected with the gas source member. The center axis of the second mounting member 221 is collinear with the center axis of the second mounting hole, so as to assist in mounting the gas source member on the workpiece template.

[0072] The shape and specification of the fixing member 220 and the position of the second mounting member 221 relative to the fixing member 220 are various, as long as the center axis of the second mounting member 221 arranged on the fixing member 220 is collinear with the center axis of the second mounting hole.

[0073] The structure of the fixing member is described in two possible implementation manners below, and it should be understood that the following description is only for understanding and does not specifically limit.

[0074] Example one: the fixing member 220 includes a U-shaped fixing portion 2200 and a connecting portion 2201, the connecting portion 2201 is located in the U-shaped slot of the U-shaped fixing portion 2200, and the height of the U-shaped fixing portion 2200 is less than the height of the connecting portion 2201. The fixing member 220 described above can be an integral structure, or the U-shaped fixing portion 2200 and the connecting portion 2201 can be fixed together by welding or bonding. In actual use, the U-shaped fixing portion 2200 is fixed on the base frame 20 by bolts. Further, the U-shaped slot opening of the U-shaped fixing portion 2200 and the second end of the second mounting member 221 both face the workpiece template.

[0075] Example two: the fixing member described above includes a first fixing block and a second fixing block, the shapes of the first fixing block and the second fixing block are both cuboids, but the length and width of the second fixing block are both less than the length and width of the first fixing block. The second fixing block is arranged on the top surface of the first fixing block, and the side surface of the second fixing block facing the workpiece template is in the same plane as the side surface of the first fixing block facing the workpiece template.

[0076] The second mounting member 221 described above can be a pin shaft. The air source member can include an air nozzle 120 and an air plug 121. In the embodiment of the application, the auxiliary mounting device 2 includes two air source mounting structures 22 symmetrically distributed along the center line B-B'. Further, the two second mounting holes on the slide plate body 10 are used to mount the air nozzle 120 and the air plug 121 respectively.

[0077] As a possible implementation, referring to Figure 7 , Figure 13 and Figure 14 , the deflector to be assembled into the slide plate body 10 is an L-shaped deflector 13, the L-shaped deflector 13 includes a first body 130 and a second body 131 connected perpendicularly to each other, the first body 130 has a deflector mounting hole.

[0078] The deflector mounting structure 23 described above can include a backing plate, a limiting member 231 and a second mounting assembly 232. The backing plate is arranged on the bearing surface 201, the limiting member 231 is located on one side of the backing plate, the L-shaped deflector 13 is arranged on the backing plate, and the second body 131 abuts against the limiting member 231. The backing plate and the limiting member 231 are both located between the second mounting assembly 232 and the workpiece template, and the second mounting assembly 232 is used to make the fastener penetrate the deflector mounting hole and the third mounting hole, so that the first body 130 is tightly connected with the workpiece template.

[0079] Exemplarily, along the second direction N, the limiting piece 231 is located at one side of the pad plate. Along the length extension direction L2 of the second clamping groove 205, the second mounting assembly 232 is located at one side of the pad plate and the limiting piece 231, and the second direction N is perpendicular to the length extension direction L2 of the second clamping groove 205. Further, the first body 130 is towards the workpiece template.

[0080] In an alternative way, referring to Figure 7 、 Figure 13 and Figure 14 , the pad plate is an L-shaped pad plate 230, which comprises a first plate body 2300 and a second plate body 2301 connected perpendicularly to each other, the first body 130 is arranged on the first plate body 2300, the second body 131 is arranged on the second plate body 2301, and the second plate body 2301 abuts against the side surface of the limiting piece 231.

[0081] Exemplarily, the size of the L-shaped pad plate 230 is completely consistent with that of the L-shaped flow guide plate 13, which is beneficial to ensure the accuracy of the relative position between the L-shaped flow guide plate 13 to be assembled and the slide plate body 10, and improve the quality of the assembled pantograph slide plate 1. Further, the limiting piece 231 is a cuboid limiting piece, the height of the cuboid limiting piece is greater than or equal to the height of the L-shaped pad plate 230 and the L-shaped flow guide plate 13, and the side surface of the cuboid limiting piece is in contact with the second plate body 2301. The position of the L-shaped flow guide plate 13 in the second direction can be limited by the limiting piece 231, so as to further ensure the accuracy of the relative position between the L-shaped flow guide plate 13 to be assembled and the slide plate body 10. The pad plate and the limiting piece 231 can be integrally formed, or can be fastened and connected by welding or bonding.

[0082] In an alternative way, referring to Figure 7 、 Figure 13 and Figure 14 , the base frame 20 is provided with the second clamping groove 205, and the pad plate and the limiting piece 231 are located between the second clamping groove 205 and the workpiece template. Exemplarily, the bearing plate 203 is provided with the second clamping groove 205, and the length extension direction L2 of the second clamping groove 205 is towards the pad plate, and the second clamping groove 205 is spaced apart from the pad plate and the limiting piece 231. Further, the center line C-C’ of the second clamping groove 205 is perpendicular to the workpiece template.

[0083] The second mounting assembly 232 can comprise a second sliding block assembly 2320 and a third mounting piece 2321. The second sliding block assembly 2320 is in sliding connection with the second clamping groove 205, and the third mounting piece 2321 is arranged on the second sliding block assembly 2320. The second sliding block assembly 2320 is used to drive the third mounting piece 2321 to approach or move away from the pad plate, and the third mounting piece 2321 is used to make the fastener penetrate the flow guide plate mounting hole and the third mounting hole, so as to fasten and connect the L-shaped flow guide plate 13 and the workpiece template.

[0084] Exemplarily, the second mounting assembly 232 includes two third mounting members 2321, each of which can include a bearing cover 24, a hex deep socket 25 and two bearings 26 in the prior art. The two hex deep sockets 25 included in the two third mounting members 2321 correspond to the two guide vane mounting holes on the first body 130 respectively. In the embodiment of the application, the two third mounting members 2321 share the two bearing covers 24. Four bearing holes are arranged in a matrix inside the first slider assembly 2110, and the four bearings 26 are arranged in the four bearing holes correspondingly. Further, the bearing covers 24 are fixed on the two end faces of the second slider assembly 2320 where the bearings 26 are arranged. Along the length extension direction L2 of the second clamping groove 205, the hex deep socket 25 penetrates through the two bearings 26 arranged oppositely. In the embodiment of the application, for the same L-shaped guide vane 13, the distance between the centers of the two hex deep sockets 25 is equal to the distance between the centers of the two third mounting holes arranged on the workpiece template.

[0085] In an alternative way, referring to Figure 13 and Figure 14 , the second slider assembly 2320 can include a third slider 2322 and a fourth slider 2323. The third slider 2322 is in sliding connection with the second clamping groove 205, and the third slider 2322 is arranged spaced apart from the inner side wall of the second clamping groove 205. The fourth slider 2323 is arranged on the third slider 2322, and the third slider 2322 and the fourth slider 2323 are arranged in a stepped manner. Exemplarily, along the second direction N, the width of the fourth slider 2323 is smaller than the width of the third slider 2322. The second slider assembly 2320 can be integrally formed, or the third slider 2322 and the fourth slider 2323 can be fastened and connected by welding or bonding and the like.

[0086] In an alternative way, referring to Figure 13 and Figure 14 , the second mounting assembly 232 can further include a second pressing block 2324 arranged on the bearing surface 201, and the second pressing block 2324 is located on the side face of the fourth slider 2323. The second pressing block 2324 covers the third slider 2322, and along the height direction H2 of the second slider assembly 2320, the second pressing block 2324 is arranged spaced apart from the third slider 2322.

[0087] Exemplarily, a portion of the fourth sliding block 2323 that is not covered by the third sliding block 2322 is defined as a second step portion, and the second pressing block 2324 covers and is spaced apart from the second step portion (i.e., along the height direction H2 of the second sliding block assembly 2320, there is a gap between the second pressing block 2324 and the second step portion). At this time, not only can the smooth sliding of the second sliding block assembly 2320 be ensured, but also the second sliding block assembly 2320 can be prevented from being detached from the second clamping groove 205 during sliding, and the stability of the second mounting assembly 232 can be ensured. In the embodiment of the present application, one second pressing block 2324 is arranged on each of the left and right sides of the second sliding block assembly 2320. Further, the auxiliary mounting device 2 includes two flow guide plate mounting structures 23 that are symmetrically distributed along the center line B-B'. Therefore, the base frame 20 is provided with two second clamping grooves 205 that are symmetrically distributed along the center line B-B'.

[0088] In an alternative manner, the third sliding block 2322 is spaced apart from the inner side wall of the second clamping groove 205.

[0089] Exemplarily, along the second direction N, the distance between the two ends of the third sliding block 2322 and the inner side wall of the second clamping groove 205 can be set according to actual conditions. At this time, the third sliding block 2322 can be moved along the second direction N, i.e., the second sliding block assembly 2320 is moved along the second direction N to drive the third mounting member 2321 arranged on the second sliding block assembly 2320 to move along the second direction N. Based on this, the application range of the second mounting assembly 232 can be expanded, and the application scenarios of the flow guide plate mounting structure 23 can be increased. It should be understood that along the second direction N, a rectangular hole can be formed in the second pressing block 2324, and the bolt 27 penetrates through the rectangular hole to fasten the second pressing block 2324 to the base frame 20. Moreover, along the second direction N, the width of the bolt 27 is less than the length of the rectangular hole. At this time, the second pressing block 2324 can be moved along the second direction N while ensuring that the bolt 27 is fixed, so as to ensure that the second pressing block 2324 covers the second step portion.

[0090] In summary, as can be known from the foregoing description, the specific structures of the bracket mounting structure 21, the gas source mounting structure 22, and the flow guide plate mounting structure 23 are different. At this time, the workers can quickly distinguish and identify the corresponding to-be-assembled equipment of each mounting structure according to the above mounting structures, so as to avoid errors in the mounting positions of one or more of the bracket 11, the gas source member, or the flow guide plate, and play a foolproof role. At the same time, the assembly efficiency of the workers can be improved, and the time for distinguishing and identifying the mounting positions can be saved.

[0091] In the auxiliary mounting device 2, the air source mounting structure 22 is located between the bracket mounting structure 21 and the flow guide plate mounting structure 23, and the two bracket mounting structures 21 are located at the outermost sides, the distance between the two bracket mounting structures 21 is equal to the distance between the two brackets 11, the distance between the two air source mounting structures 22 is equal to the distance between the two air source members, and the distance between the two flow guide plate mounting structures 23 is equal to the distance between the two flow guide plates.

[0092] The specific use mode of the auxiliary mounting device will be described below by way of a possible implementation. It should be understood that the following description is for understanding only and is not used for specific definition.

[0093] Referring to Figures 1 to 14 In the embodiment of the present application, the pantograph slide plate 1 to be assembled includes a slide plate body 10, two brackets 11, an air nozzle 120, an air plug 121, and two L-shaped flow guide plates 13. The two brackets 11, the two L-shaped flow guide plates 13, and the air nozzle 120 and the air plug 121 are symmetrically distributed about the center line D-D' of the slide plate body 10.

[0094] In actual assembly, the staff steps on the foot pedal pneumatic switch to start the air cylinder (i.e., the driving member 2122) in the jacking assembly 212. At this time, the telescopic driving end of the air cylinder jacks up the mounting shaft (i.e., the connecting member 2121) to make the mounting shaft completely penetrate the fixing hole of the pad 210 and protrude from the pad 210. Then, the connecting hole of the bracket 11 is aligned with the mounting shaft and is sleeved on the mounting shaft. For example, the height of the positioning shaft protruding upward from the bearing surface 201 is equal to the height of the pad 210 and the bracket 11. It should be understood that the bottom surface of the bracket 11 abuts against the pad 210, and the vertical surface of the bracket 11 close to the bracket mounting structure 21 is substantially in the same vertical plane as the vertical surface of the pad 210.

[0095] Then, the air nozzle 120 and the air plug 121 are sleeved on the second ends of the two pin shafts (i.e., the second mounting members), and the outer circle of the air nozzle 120 and the air plug 121 has a screw end away from the air source mounting structure 22. The end of the slide plate body 10 on both sides (the direction of the bow mouth) is close to the bracket mounting structure 21, the slide plate body 10 is placed flat on the bearing plate 203, and the slide plate body 10 is pulled slightly so that the air nozzle mounting hole and the air plug mounting hole (i.e., the second mounting hole) on the slide plate body 10 are close to and contact the air nozzle 120 and the air plug 121 sleeved on the pin shafts, respectively. At the same time, the slide plate body 10 abuts against the first plate body 2300 of the two L-shaped spacers 230 and the two limiting members 231.

[0096] Then, the air nozzle 120 and the air plug 121 on both sides are fixed by using a ratchet open wrench. It should be understood that the air nozzle 120 and the air plug 121 are not completely fastened, and the degree of firmness of the fixation can be adjusted according to the actual situation.

[0097] Afterwards, the mounting bracket 11 is installed. Specifically, the screw is pre-fixed to the mounting portion of the hex deep socket 25 (in the embodiment of the present application, the mounting portion of the hex deep socket 25 can attract the screw by magnetic force), the first mounting member 2111 and the screw are driven by the first sliding block assembly 2110 to move towards the direction of the pad 210, so that the screw enters the mounting hole of the bracket 11 and contacts the first mounting hole of the workpiece template. Then, under the cooperation of the electric tool with torque and the socket end 250 of the hex deep socket 25, the hex deep socket 25 is rotated at low speed, so that the bracket 11 and the slide plate body 10 are connected by the screw.

[0098] Then, the L-shaped flow guide plate 13 is placed on the L-shaped pad 230 according to the installation direction requirement, wherein the first body 130 abuts against the mounting surface of the slide plate body 10, and the second body 131 abuts against the side surface of the limiting member 231. Next, the screw is pre-fixed to the mounting portion of the hex deep socket 25, the third mounting member 2321 and the screw are driven by the second sliding block assembly 2320 to move towards the direction of the first body 130, so that the screw enters the mounting hole of the L-shaped flow guide plate 13 and contacts the third mounting hole of the workpiece template (i.e. the slide plate body 10). Then, under the cooperation of the electric tool with torque and the socket end 250 of the hex deep socket 25, the hex deep socket 25 is rotated at low speed, so that the L-shaped flow guide plate 13 and the workpiece template are tightly connected by the screw. It should be understood that the degree of tight connection can be adjusted according to actual conditions. Then, the screw for installing the bracket 11 is fastened again, and the air nozzles 120 and the air plugs 121 on both sides are fastened by the ratchet open wrench. That is, it is ensured that the bracket 11, the air nozzles 120, the air plugs 121 and the L-shaped flow guide plate 13 are tightly connected with the slide plate body 10.

[0099] Finally, the staff steps on the foot pedal pneumatic switch, and the extension and retraction driving end of the pneumatic cylinder drives the mounting shaft to descend, so as to be separated from the bracket 11. Then, the staff pushes the assembled pantograph slide plate 1 away from the bracket mounting structure 21, the air source mounting structure 22 and the flow guide plate mounting structure 23, and places it at a designated position. At this point, the pantograph slide plate 1 is assembled.
