Description

Technical Field

[0001] The utility model relates to the technical field of production equipment for overhead installation devices of electric wires or cables, in particular to an automatic assembly system for spacer bar wire clamps. Background Art

[0002] Spacers are hardware that are installed on split conductors to fix the spacing between each split conductor to prevent the conductors from whipping each other and suppress breeze vibration and sub-spacing oscillation. In the overall structure of the spacer, the wire clamp is the connecting part between the spacer and the conductor, which can clamp, connect and fix the conductor, cable, etc.

[0003] The spacer bar mainly includes a wire clamp body, a wire clamp cover plate and a pin, wherein the pin is the main component for connecting the wire clamp body and the wire clamp cover plate. Specifically, the wire clamp body and the wire clamp cover plate are provided with connecting through holes or connecting holes, etc., which together constitute a connecting component. After the wire clamp body and the wire clamp cover plate are preliminarily combined, the connecting through holes and the connecting holes thereon will be aligned, and then the pin can be inserted into the connecting component to complete the connection between the wire clamp body and the wire clamp cover plate. One end of the connecting component is usually an opening for accommodating the pin to enter therein, and the other end is provided with a limiting portion for limiting the position of the pin insertion, wherein a reserved block is usually provided at the opening of the connecting component. After the pin is inserted, the entire pin is placed in the connecting component, so it is necessary to melt the reserved block at the opening, and then use the material to complete the welding closure of the opening to prevent the pin from falling off during subsequent use. After the welding is completed, a welding protrusion will be generated at the original opening, and then the welding protrusion needs to be polished to ensure the smoothness of the wire clamp surface. After the wire clamp body and the wire clamp cover are fully assembled, the wire clamp cover can be rotated and moved around the position where the pin is inserted, and the grooves of the wire clamp cover and the wire clamp body are combined to form a complete wire clamping groove for clamping the cable.

[0004] Therefore, the processing flow of the spacer bar wire clamp mainly involves the preliminary combination of the wire clamp body and the wire clamp cover plate, pressing pins, welding, and grinding. Among them, when pressing the pin in the pressing pin step, it is necessary to align the corresponding connecting parts and apply corresponding pressure to complete the step; in the welding step, the welding points involve multiple positions on the reserved block to ensure that the melted material flows from the surroundings to the opening, so as to facilitate the welding and sealing of the opening; in the grinding step, it is also necessary to grind the welding protrusions with a larger range. In the overall production process of the spacer bar wire clamp, if the production steps are manually promoted, the processing requirements of each step will result in a long processing time and huge manpower consumption. Therefore, there is an urgent need for an automatic assembly system for spacer bar wire clamps to increase the production speed of spacer bar wire clamps, reduce manpower consumption and ensure product processing accuracy. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide an automatic assembly system for spacer bar wire clamps, in which an automatic pinning device, an automatic welding device, an automatic grinding device and other equipment are adopted to improve the efficiency of the pinning, welding and grinding steps in the production process of the spacer bar wire clamps. At the same time, the devices are connected in series through the structure on the base, which on the one hand ensures the rapid connection between the steps, and on the other hand ensures that the spacer bar wire clamps can be quickly and accurately placed in the corresponding working position, ensuring that the spacer bar wire clamps match the construction position of the corresponding device, and ensuring the accuracy of the processing during repeated processing.

[0006] The utility model is realized through the following technical solutions.

[0007] A spacer rod wire clamp automatic assembly system, characterized in that it includes an automatic pinning device, an automatic welding device, an automatic grinding device and a base; the base includes a receiving seat for supporting the spacer rod wire clamp and a load-bearing seat for supporting the receiving seat; the receiving seat and the load-bearing seat are connected by a displacement kit, and the displacement kit includes a driving device and a displacement control device for controlling the displacement of the receiving seat; at least one set of limiting kits is installed on the receiving seat, and the limiting kit has a limiting structure that is compatible with the shape of the spacer rod wire clamp; wherein the automatic pinning device, the automatic welding device and the automatic grinding device are sequentially arranged along the moving path of the limiting kit, and the automatic pinning device, the automatic welding device, the automatic grinding device and the displacement kit are all linked to a general control device.

[0008] In this structure, the object bearing seat can be displaced relative to the load bearing seat, and the several sets of limit kits installed on it will also be displaced accordingly, thereby driving the movement of the spacer wire clamps on it. The displacement path of the limit kit will directly affect the displacement path of the spacer wire clamp, so each automation device is set on the movement path of the limit kit.

[0009] The limiting structure in the limiting kit is adapted to the shape of the spacer rod clamp and can be used to fix the spacer rod clamp to be processed on the object holder. Therefore, when the spacer rod clamp is placed in place, it can be moved to the processing position of the corresponding automatic device in sequence according to the production steps.

[0010] The base as a whole can adopt a turntable structure, a straight line assembly line structure, etc.

[0011] When the position of the automatic device is fixed, the relative position relationship between the processing positions of each automatic device has also been confirmed. In order to ensure the accuracy of repeated processing, the spacer wire clamp should be moved into place during each step. The displacement control device in the displacement kit can control the displacement amount of the object holder, such as the displacement distance, and the control of the object holder actually realizes the control of its upper limit kit. When processing, the main control device can ensure that the object holder and the spacer wire clamp on it are accurately displaced to the corresponding processing position by setting the displacement control device.

[0012] As a further improvement of the present invention, the limiting kit further includes a clamping kit, and the clamping kit has a main clamping surface for clamping the spacer rod clamp.

[0013] As a further improvement of the present invention, the object bearing seat is a multi-station turntable structure, and several sets of the limit kits rotate around the same center. A loading station, the automatic pin pressing device, the automatic welding device, the automatic grinding device, and the unloading station are arranged in sequence along the moving direction of the limit kit. Under this structure, the layout of each automatic device will also be arranged around the load-bearing seat, and the overall footprint of the spacer bar wire clamp automatic assembly system is greatly reduced.

[0014] As a further improvement of the present invention, the material unloading station includes a clamping and placing kit, and a third positioning kit with the clamping and placing kit installed at one end, and the clamping and placing kit and the third positioning kit are both linked to the general control device. It is no longer necessary to manually transfer and place materials at the material unloading station, which further reduces the labor required to operate the automatic assembly system of the spacer bar clamp. At the same time, the execution speed of the overall steps of "clamping-transferring-placing-returning" of the automated material unloading operation is adjustable. After being linked to the general control device, it can cooperate with other automatic devices to unify the overall production rhythm of the spacer bar clamp.

[0015] As a further improvement of the present invention, the automatic pin pressing device includes a pressure kit, a pin supply kit and a vibration auxiliary kit; wherein the pressure kit has a pressure component, and the pressure path of the pressure component is adapted to the pressing angle of the pin; the pin supply kit has a pin transmission component for moving the pin to the bottom of the pressure kit, and a guide through hole is provided below the pin transmission component, and the inner wall of the guide through hole conforms to the movement trajectory of the pin in the pressure path; the vibration auxiliary kit has a vibration source and a vibration transmission component, and the vibration transmission component has a vibration receiving end in contact with the vibration source and a vibration transmission end in contact with the spacer wire clamp.

[0016] The pressing angle of the pin determines whether the pin will rub against the inner wall of the connecting part when it is pressed into the connecting part. On the one hand, it affects the pressing process of the pin, and on the other hand, it determines whether it will cause wear or even damage to the parts. Therefore, after the correct pressing angle is selected, the pressing path of the pressing member should be consistent with the pressing angle of the pin to avoid the movement of the pin being offset during the pressing process. During the pressing of the pin, the inner wall of the guide hole fits with the outer surface of the pin, so that after the setting of the guide hole is completed, the angle of the pin when passing through the guide hole is limited, that is, the pressing angle of the pin is limited so that it does not deviate.

[0017] The vibration auxiliary component acts on the spacer wire clamp placed on the limit kit, specifically, it can drive a small relative displacement between the wire clamp body and the wire clamp cover plate, ensuring that during this period, the second connecting through hole must be aligned with the first connecting through hole and the connecting hole, thereby making the accommodation space in the connecting component continuous, allowing the pin to be pressed in smoothly. At the same time, during the pin pressing process, slight friction will inevitably occur between the pin and the inner wall of the connecting component, and the slight vibration can simultaneously bring about a small displacement of the pin, avoiding the friction from preventing the pin from being pressed in normally.

[0018] As a further improvement of the present invention, the vibration auxiliary kit is movably mounted on the fixed bracket, the vibration auxiliary kit includes an inner auxiliary kit and an outer auxiliary kit, and the vibration transmitting end includes an outer vibration transmitting end in the outer auxiliary kit that contacts the two sides of the spacer wire clamp, and an inner vibration transmitting end in the inner auxiliary kit that contacts the inner wall of the slot of the spacer wire clamp cover. Under this structure, it is ensured that the vibration auxiliary kit can be moved to a position that does not affect the movement of the spacer wire clamp before and after the pressing pin works.

[0019] As a further improvement of the utility model, a guide base is provided at the bottom of the pyramidal pin component, the supporting surface of the guide base is used to support the pyramidal pin component, a guide component is installed on the guide base, and the guide through hole is provided on the guide component. Under this structure, guide components with guide through holes of different sizes can be replaced, and different sizes of limit kits can be replaced and installed on the support seat, so that different sizes of spacer bar wire clamps can be processed.

[0020] As a further improvement of the present invention, the automatic welding device includes a welding component, a first positioning kit on which the welding component is installed at one end, and a movably installed protection kit; wherein, when welding is performed, the protection kit has a protective space for accommodating the points to be processed on the spacer bar clamp. In the present invention, it is necessary to heat and weld multiple points on the reserved blocks arranged around the opening to ensure that the opening can be sealed after the reserved blocks melt. Therefore, the first positioning kit needs to be able to drive the welding component to move quickly, quickly reach different positions and complete the welding work. When welding is performed, the protection kit falls onto the spacer bar clamp, forming an encircling barrier around the points to be processed, placing the points to be processed in the protection space to prevent the splashing of welding slag, etc.; after the welding work is completed, the protection kit moves to a position where it does not block the displacement of the spacer bar clamp.

[0021] As a further improvement of the present invention, the automatic grinding device includes a grinding device, a second positioning kit with the grinding device installed at one end, and a positioning auxiliary device; wherein the positioning auxiliary device is movably installed on the second fixed bracket, and the positioning auxiliary device has an auxiliary clamping surface clamped on the spacer wire clamp. Since the welding convex part left after the welding work is completed is relatively large, basically covering the original opening and part of the surrounding structure, when performing the grinding work, the second positioning kit is required to drive the grinding device to move quickly, so that the grinding working surface on the grinding device can move quickly, thereby realizing a wide range of grinding work.

[0022] As a further improvement of the utility model, a cooling kit is arranged between the automatic welding device and the automatic grinding device, and the cooling kit includes at least one cooling device and a fixing frame on which the cooling device is mounted at one end, and the cooling working end of the cooling device faces the spacer wire clamp on the limiting kit in the cooling step. The cooling step after welding helps to stabilize the organizational structure of the welding point and its vicinity, and reduce material deformation and internal stress caused by the influence of welding heat. After cooling, the structure of the welding point and its accessories are in a stable blocking state. Grinding in a stable organizational state can ensure that the overall dimensional accuracy and shape of the structure near the welding point meet the requirements, thereby improving the quality of welding. The cooling kit can include only one cooling device, and the cooling device cools the welding point only from one angle; it can also include multiple cooling devices, which can cool the welding point from multiple angles at the same time, ensuring that the welding point and the structure near it can be cooled and in a stable state.

[0023] The beneficial effects of the utility model include:

[0024] (1) Each automatic device is arranged along the moving path of the limit kit according to the processing order, and the object holder controls its displacement distance and other parameters through the displacement kit, so that the spacer bar wire clamp placed on it can be quickly and accurately moved to the processing area of ​​each automatic device. The fast movement can make the various steps closely connected, thereby improving the overall processing speed of the spacer bar wire clamp, and the precise movement can ensure that no large errors occur during the various processing steps, thereby improving the processing accuracy of the spacer bar wire clamp;

[0025] (2) The unloading station can adopt a mechanized structure to perform actions. The automatic pin pressing device, automatic welding device, and automatic grinding device also adopt a mechanized structure to control the actions. All components are linked to the overall control device. Therefore, the working speed of each processing step and the moving speed of the limit kit can be coordinated through the overall control device, so that each step is coordinated with each other, thereby improving the overall processing efficiency of the spacer wire clamp;

[0026] (3) The automatic devices involved in each step involve mechanized control components, such as positioning kits, which can ensure that after the initial parameter adjustment is completed, the subsequent repeated processing operations are highly identical, thereby ensuring a high product qualification rate; at the same time, with the functions of replacing guide components and limit kits, it can adapt to the processing of different types of spacer bar clamps after adjusting the relevant parameters, thereby improving the versatility of the spacer bar clamp automatic assembly system.

[0039] The utility model is further described in detail below based on the accompanying drawings and implementation cases.

[0040] The directional terms such as up, down, left, right, front, back, front, back, top, bottom, etc. mentioned or may be mentioned in this specification are defined relative to the structures shown in the drawings. The words "inside" and "outside" refer to the direction toward or away from the geometric center of a specific component, respectively. They are relative concepts, and therefore may change accordingly according to different locations and different usage conditions. Therefore, these or other directional terms should not be interpreted as restrictive terms.

[0041] The structure of the spacer clamp is as follows Figures 9 and 10 shown.

[0042] In this embodiment, the spacer bar wire clamp A is placed horizontally on the support 701 for processing. In this case, the connecting part A01 of the spacer bar wire clamp A is placed vertically, and the connecting part A01 includes, from top to bottom, the first connecting through hole A01-1 on the wire clamp body A-1, the second connecting through hole A01-2 on the wire clamp cover A-2, and the connecting hole A01-3 with a limit portion on the wire clamp body A-1, and a reserved block A01-4 is arranged near the opening of the connecting part A01.

[0043] Therefore, in the pin pressing step, the pin needs to be pressed vertically, and the entire pin is placed in the connecting component A01 after pressing; in the welding step, the reserved block A01-4 around the opening is heated and melted, and the melted material is used for welding, so that the opening of the connecting component A01 is closed and the entire pin is confined in the connecting component A01; in the grinding step, the welding protrusion formed at the original opening is ground. The above conditions are only used to facilitate the description of the relevant operating steps of the spacer bar wire clamp automatic assembly system, so as to understand the role of each device and its components in actual work, and do not affect the scope of protection of the claims of the utility model.

[0044] Embodiment 1:

[0045] In this embodiment, the processing flow of the spacer bar clamp A mainly involves the preliminary assembly, pressing, welding and grinding of the clamp body A-1 and the clamp cover A-2. Figure 1 As shown, it includes an automatic pinning device 2, an automatic welding device 3, an automatic grinding device 5 and a base 7. Among them, the base 7 is the main component that connects various processing steps in series.

[0046] In this embodiment, Figure 8 As shown, the base 7 includes a support seat 701 for supporting the spacer rod clamp A and a load-bearing seat 702 for supporting the support seat 701. The support seat 701 and the load-bearing seat 702 are connected by a displacement kit, wherein the displacement kit includes a driving device and a displacement control device for controlling the displacement of the support seat 701. A limit kit 701-1 is installed on the support seat 701. The limit kit 701-1 is used to fix the spacer rod clamp to be processed, so the moving path of the limit kit 701-1 determines the layout position of the remaining automatic devices for processing. Several sets of limit kits 701-1 can be arranged on one support seat 701. In this embodiment, eight sets of limit kits 701-1 are installed on the support seat 701.

[0047] The displacement relationship between the object holder 701 and the position limiting assembly 701-1 will change with the structural change of the base 7. Correspondingly, the displacement controlled by the displacement control device will also change.

[0048] For example, if the base 7 as a whole adopts the structure of an elliptical conveyor belt, the load-bearing seat 702 is in the shape of an elliptical ring as a whole, and the object-bearing seat 701 can be composed of several movable blocks, and a limiting kit 701-1 is provided on a single movable block, and several movable blocks are relatively displaced on the load-bearing seat 702. Under this structure, the displacement of the object-bearing seat 701 is consistent with the displacement path and direction of the limiting kit 701-1. At this time, the driving device can adopt a driving structure such as a roller or a roller arranged at the bottom of the object-bearing seat 701. The displacement control device mainly controls the displacement distance of the object-bearing seat 701, and can adopt a structure such as a telescopic limiting block. When the object-bearing seat 701 needs to be stopped, the limiting block extends to block it; when the object-bearing seat 701 is allowed to move, the limiting block contracts and does not block it.

[0049] If the base 7 as a whole adopts a turntable structure, in which a driving device is installed on the load-bearing seat 702, the driving device mainly drives the load-bearing seat 701 to rotate around its own center, and at this time the limiting kit 701-1 is arranged circumferentially around the center. The displacement path of the limiting kit 701-1 is inconsistent with that of the load-bearing seat 701, but the displacement control device can still control the limiting kit 701-1 by controlling the rotation angle of the load-bearing seat 701. Specifically, the displacement control device can adopt structures such as an electric control switch to limit the output time of the rotation driving force of the driving device each time, and finally achieve the effect of controlling the rotation angle of the single limiting kit 701-1.

[0050] The limiting kit 701-1 installed on the object holder 701 has a limiting structure that matches the shape of the spacer wire clamp A. In this embodiment, Figure 2 As shown, the limiting structure includes a first protrusion α for supporting the spacer bar wire clamp A, so that the connecting component A01 can remain vertical, and a second protrusion β adapted to the slot A02 of the wire clamp body A-1, which can be filled in the slot A02. The limiting component can ensure that the spacer bar wire clamp A will not undergo a large displacement on the support seat 701, especially a horizontal displacement. This ensures that as long as the spacer bar wire clamp on it is moved into place during each processing link during the first debugging, the support seat 701 is used to drive the spacer bar wire clamp thereon to move into place during each processing link. In the subsequent repeated processing links, after the spacer bar wire clamp A is placed on the limiting kit 701-1, the spacer bar wire clamp A to be processed can be moved into place during the processing link, thereby ensuring the accuracy of the processing.

[0051] On the moving path of the limit kit 701-1, according to the processing order of the spacer wire clamp A, an automatic pinning device 2, an automatic welding device 3 and an automatic grinding device 5 are arranged in sequence, wherein the automatic pinning device 2, the automatic welding device 3 and the automatic grinding device 5 are all linked to the general control device, so that the staff can adjust the processing speed of each automatic device and the relevant parameters involved in the processing through the general control device, so that the various automatic processing devices can cooperate with each other, and there will be no situation where the processing speed of some steps is slow and the processing speed of some steps is too fast, which will lead to the overall processing rhythm being out of balance.

[0052] Preferably, the limiting kit 701-1 further includes a clamping kit 701-2, and the clamping kit 701-2 has a main clamping surface for clamping the spacer wire clamp A. In this embodiment, the wire clamp body A-1 and the wire clamp cover A-2 are conventional left-right structures, such as Fig.10As shown, after the initial installation of the spacer wire clamp A, the wire clamp cover A-2 may tip over, especially when the support seat 701 drives the limit kit 701-1 to move, usually in the horizontal direction, and the possibility of the wire clamp cover A-2 tipping due to inertia is further increased. The main clamping surface of the clamping kit 701-2 can always fit on both sides of the spacer wire clamp A during the displacement of the support seat 701, ensuring that the wire clamp cover A-2 will not tip over.

[0053] Preferably, in this embodiment, if Figure 8 As shown, the support seat 701 adopts a multi-station turntable structure, and eight limit kits 701-1 rotate and move around the center of the support seat 701. A loading station 1, an automatic pinning device 2, an automatic welding device 3, an automatic grinding device 5, and a unloading station 6 are arranged in sequence along the moving direction of the limit kit 701-1. Among them, the loading station 1 is mainly used to facilitate the staff to place the initially assembled spacer bar wire clamp A on the support seat 701 located in the station, and the unloading station 6 is mainly used to facilitate the construction staff to remove the processed spacer bar wire clamp A. The multi-station state structure can ensure that each automatic device is arranged around the base 7. Compared with the conveyor belt structure, the overall footprint of the spacer bar wire clamp automatic assembly system is greatly reduced.

[0054] Preferably, if Figure 7 As shown, the blanking station 6 includes a clamping and placing kit 601, and a third positioning kit 602 with the clamping and placing kit 601 installed at one end. The third adjustment kit used in this embodiment includes a first horizontal displacement member 801, a second horizontal displacement member 802, and a vertical displacement member 803, wherein the first horizontal displacement member 801 is used to drive the horizontal movement of the second horizontal displacement member 802, the second horizontal displacement member 802 is used to drive the horizontal movement of the vertical displacement member 803, and the vertical displacement member 803 is used to drive the vertical movement of the clamping and placing kit 601, wherein the moving paths of the targets of the first horizontal displacement member 801 and the second horizontal displacement member 802 are perpendicular to each other on the horizontal plane. Under this structure, the third positioning kit 602 can realize the movement of the clamping and placing kit 601 in three-dimensional space, and the clamping and placing kit 601 and the third positioning kit 602 are both linked to the general control device, and the moving distance of the clamping and placing kit 601 in three-dimensional space can be quantitatively controlled by the general control device, further improving the accuracy of control. The third adjustment kit may also adopt any device that can drive the clamping kit 601 to move in three-dimensional space, such as a robotic arm.

[0055] Preferably, if Figure 2~3As shown, the automatic pin pressing device 2 includes a pressure kit 201, a pin supply kit 202 and a vibration auxiliary kit 203; wherein, the pressure kit 201 has a pressure member, and the pressure path of the pressure member is adapted to the pressing angle of the pin. In this embodiment, the pin should be vertically pressed into the connecting component A01, so the pressure path is vertically arranged. The pin supply kit 202 has a multi-pin member 202-1 that moves the pin to the bottom of the pressure kit 201. In this embodiment, the multi-pin member 202-1 includes a receiving groove, in which the received pin is in a vertically placed state. After the multi-pin member 202-1 is moved for supplying and pinning, the pin is placed below the pressure member, and when the pressure member starts to apply pressure, it can directly act on the pin.

[0056] A guide hole 201-1a is provided below the pin component 202-1. After the pin supply movement is completed and before the pin pressing work is carried out, the pin is placed on the top of the guide hole 201-1a. The inner wall of the guide hole 201-1a conforms to the movement trajectory of the pin in the pressing path, so that when the pin passes through the guide hole 201-1a, the outer surface of the pin can be tightly attached to the inner wall of the guide hole 201-1a, so that the guide hole 201-1a can guide the direction of the movement trajectory of the pin.

[0057] The automatic pin pressing device 2 also includes a vibration auxiliary kit 203, which has a vibration source and a vibration transmission component. The vibration source can be any component that can provide vibration, such as a vibration motor. The vibration transmission component has a vibration-receiving end connected to the vibration source and a vibration transmission end in contact with the spacer wire clamp A. During the pin pressing operation, the outer surface of the pin is in close contact with the inner wall of the connecting component A01, which may cause a large friction force between the two, and thus make it difficult for the pin to be smoothly pressed into the connecting component A01. The vibration auxiliary kit 203 causes the spacer wire clamp A to produce a small displacement through the vibration transmission component, which can make the pin no longer contact too closely with the inner wall of the connecting component A01, so that the pin can smoothly enter the connecting component A01, thereby completing the pin pressing operation.

[0058] Preferably, if Figure 4 As shown, the vibration auxiliary kit 203 includes an inner auxiliary kit 203-1 and an outer auxiliary kit 203-2. Therefore, the vibration transmitting end mainly includes two components, namely, the outer vibration transmitting end in the outer auxiliary kit 203-2 that contacts the two sides of the spacer wire clamp A, and the inner vibration transmitting end in the inner auxiliary kit 203-1 that contacts the inner wall of the slot of the wire clamp cover A-2. When a structure that contacts the two ends of the spacer wire clamp A appears in the vibration transmitting component, such as Figure 2As shown, the vibration auxiliary kit 203 needs to be movably installed on the fixed bracket, that is, the vibration auxiliary kit 203 can be moved on the fixed bracket. The purpose is that when the spacer bar clamp A to be processed moves to the working area of ​​the automatic pinning device 2, the vibration auxiliary kit 203 is displaced so that the vibration transmission end of the vibration transmission component can contact the spacer bar clamp A; and before and after the pinning work, when the limit kit 701-1 moves with the spacer bar clamp A, the vibration kit is moved so that the vibration transmission component will not block the limit kit 701-1 from moving with the spacer bar clamp A.

[0059] Among them, the vibration-transmitting component includes two sets of auxiliary kits inside and outside, which can make the two form internal and external joint vibration. In this process, it plays a certain clamping role on the spacer wire clamp A to prevent its vibration amplitude from being too large and causing a large overall displacement. Among them, the inner auxiliary kit 203-1 only acts on the inner wall of the slot of the wire clamp cover A-2. On the one hand, it cooperates with the outer auxiliary kit 203-2 to play the above-mentioned partial clamping role on the wire clamp cover A-2, ensuring that during vibration, the wire clamp cover A-2 is driven to move as a whole, ensuring that the connecting through hole on the wire clamp cover A-2 is always in a vertical state without tilting, so as to ensure that when the pin is pressed down in a vertical direction, the bottom end of the pin will not conflict with the inner wall of the connecting through hole; on the other hand, under this structure, the wire clamp cover A-2 has a stronger vibration effect than the wire clamp body A-1, ensuring that a certain relative position change can occur between the wire clamp cover A-2 and the wire clamp body A-1, and in this process, there will be a greater probability of alignment between their respective connecting through holes, further ensuring the smooth insertion of the pin.

[0060] Preferably, if Figure 3 As shown, the bottom of the pyramid pin component 202-1 is provided with a guide base 204, and the supporting surface of the guide base 204 is used to support the pyramid pin component 202-1. In this embodiment, the pyramid pin component 202-1 includes a receiving groove, in which the pin is placed vertically, so before the pin is displaced to the top of the guide through hole 201-1a, the guide base 204 also has the function of supporting the pin. At the same time, a guide member 204-1 is installed on the guide base 204, and the guide through hole 201-1a is set on the guide member 204-1. When processing different types of spacer bar clamps A, spacer bar clamps A and pins of different sizes and shapes are involved, so it is necessary to replace the limit kits 701-1 of different sizes and shapes, and replace the guide through hole 201-1a adapted to the size of the pin. In this embodiment, it is achieved by replacing the corresponding guide member 204-1, thereby improving the versatility of the automatic assembly system of the spacer bar clamp.

[0061] In the case where the receiving groove in the pin supply member is larger than the size of the pin, the receiving groove can only guide the pin to be in a vertical state as a whole without falling. In this case, the guide member 204-1 is preferably provided with a guiding structure. In this embodiment, a hole chamfering structure is provided at the top of the guide through hole 201-1a, which can guide the bottom end of the pin displaced to the top of the guide through hole 201-1a to quickly embed into the guide through hole 201-1a, thereby making the guide through hole 201-1a play the role of guiding the pin in a vertical state. Further preferably, the bottom of the adopted pin also has a chamfering structure of the same size, which can quickly adapt to the hole chamfering.

[0062] Preferably, if Figure 5 As shown, the automatic welding device 3 includes a welding component 301, a first positioning kit 302, and a movably installed protection kit 303, wherein the welding component 301 performs the main welding work. During the welding work, the welding heating points involved are distributed at multiple locations on the reserved blocks A01-4 around the opening of the connecting component A01, so it is necessary to move the welding component 301. Therefore, the first positioning kit 302 can adopt a mechanical device or a mechanical arm structure similar to the third positioning kit 602, which can realize the displacement of the welding component 301 in three-dimensional space. The protection kit 303 can be moved, that is, when the welding work is performed, the protection kit 303 is displaced to be placed on the spacer wire clamp A to be processed. At this time, the protection kit 303 surrounds the points to be welded on the spacer wire clamp A, so that the welding points and their surrounding structures are placed in the protective space of the protection kit 303. On the one hand, the protection kit 303 prevents the splashing welding slag from affecting the surrounding components, and on the other hand, the protection kit 303 blocks the high-intensity bright light generated by welding to protect the surrounding staff. Before and after welding, the protection kit 303 is returned to its original position to avoid obstruction when the limiting kit 701-1 carrying the spacer wire clamp A moves.

[0063] Preferably, if Figure 6 As shown, the automatic grinding device 5 includes a grinding component 501, a second positioning kit 502 and a positioning auxiliary kit, wherein the grinding component 501 performs the main grinding work, and can use grinding devices such as a grinding wheel and a grinding belt. Since the scope involved in the grinding work is large, it is necessary to move the grinding component 501. Among them, the second positioning kit 502 can use a mechanical device or a mechanical arm structure similar to the third positioning kit 602, which can realize the displacement of the grinding component 501 in three-dimensional space.

[0064] At the same time, the positioning auxiliary device 503 has an auxiliary clamping surface clamped on the spacer wire clamp A, which is used to assist in clamping the spacer wire clamp A during the grinding work to prevent it from being offset and causing inaccurate grinding positions. Since the auxiliary clamping surface is clamped on both sides of the spacer wire clamp A, the positioning auxiliary device 503 is also movably installed on the corresponding second fixed bracket, which is convenient for the displacement of the positioning auxiliary device 503 before and after the grinding work, until it does not block the movement of the spacer carrying the limit kit 701-1.

[0065] In this embodiment, the automatic welding device 3 and the automatic grinding device 5 are linked to the general control device, which can realize accurate adjustment of the processing position and processing speed of the welding component 301 and the grinding component 501. When performing the initial work, preliminary debugging can be performed according to the size and shape of the spacer wire clamp A, such as determining the mobile position adjustment and welding speed adjustment of the welding component 301 during welding work, and the grinding position adjustment of the grinding component 501 during grinding work. The mutual cooperation between various automatic devices is realized to ensure the accuracy of processing and the consistency of processing rhythm between various devices.

[0066] Embodiment 2:

[0067] The difference between this embodiment and embodiment 1 is that in this embodiment, Figure 1 As shown, a cooling kit 4 is provided between the automatic welding device 3 and the automatic grinding device 5 to cool the welding point and its attached components after the welding work is completed, and then enter the grinding work link.

[0068] In this embodiment, the cooling kit 4 includes two cooling devices 401, namely two air coolers. Both air coolers are installed on the corresponding fixing frame 402, and the two air coolers are arranged in sequence along the moving path of the limiting kit 701-1, and are placed above the base 7, with their air outlets facing the location of the spacer wire clamp A. In this embodiment, when the spacer wire clamp A is moved to the cooling working position, the two air coolers are located at the top of the spacer wire clamp A, so the air outlets of the air coolers are vertically downward, and the top surface where the welding point of the spacer wire clamp A is located can be cooled.

[0069] Finally, it should be noted that the above implementation cases are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the above implementation cases, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the above implementation cases, or replace some of the technical features therein with equivalents. These modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the implementation cases of the utility model.
