Since different products have different requirements for the shape, size and installation position of fixtures, the fixtures on the production line need to be frequently replaced to meet the processing requirements of different products. How to facilitate the quick switching of fixtures has been pursued by those skilled in the art. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a fixture switching component, which facilitates the quick switching of fixtures by improving the structure of the fixture switching component.

[0004] To achieve the above purpose, the utility model provides a fixture switching component for fixing a fixture component, and the fixture component includes a fixture body and a seat body for supporting the fixture body; the fixture switching component includes a switching device and a lifting device, and the lifting device is used to place the fixture component on the switching device; the switching device includes two supporting parts arranged oppositely along the arrangement direction of the supporting parts, the supporting parts are used to support the fixture component, there is a spacing part between the two supporting parts, the spacing part allows the lifting device to pass through, and a stop part is further arranged in the spacing part, and the stop part forms a direct or indirect stop with the fixture component in the extending direction of the spacing part and can be slidably matched with the fixture component in the height direction.

[0005] By adopting the fixture switching component in the present application, the fixture component can be quickly switched through the cooperation between the lifting device and the switching device. During the switching process, the stop part forms a stop for the fixture component in the horizontal direction, and at the same time, in the height direction, the fixture component is positioned in a way of forming a sliding fit with the fixture component, ensuring the connection position between the fixture component and the supporting part. Thus, it can be ensured that each time the fixture component is replaced, the new fixture component can be accurately placed at the predetermined position of the supporting part; this not only improves the assembly accuracy but also avoids the processing errors caused by inaccurate positioning; compared with the traditional fixture switching device, the structure is simplified and the switching efficiency of the fixture component is improved.

[0006] Optionally, the stop part includes at least two guide rods, and the two guide rods are arranged at intervals along the distribution direction of the supporting parts; the switching component further includes an adapting part, and the adapting part can be arranged on the seat body, and each adapting part is in rolling fit with the corresponding guide rod.

[0007] In this embodiment, by arranging at least two guide rods, the seat body can be accurately positioned, preventing the seat body from being misaligned during a certain process. In addition, by means of the sliding fit between the adapter portion provided on the seat body and the guide rods, the friction between the adapter portion and the guide rods can be significantly reduced, preventing the guide rods from being worn during long-term use and reducing the positioning accuracy.

[0008] Optionally, the adapter portion includes a bearing and a bracket connected to the seat body. The inner ring of the bearing is fixedly connected to the bracket through a pin shaft, and the outer ring of the bearing contacts the guide rod. Thus, by means of the rolling fit between the outer ring of the bearing and the guide rod, wear on the guide rod can be avoided.

[0009] Optionally, each of the guide rods has an arc section that extends in the height direction, and the position where the outer ring of each bearing contacts the guide rod is located on the arc section. This can minimize the contact area between the guide rod and the adapter portion, further preventing wear of the guide rod.

[0010] Optionally, the fixture switching assembly further includes an adjustment beam. The adjustment beam has an L-shaped structure and is arranged on the seat body, corresponding to each of the brackets one by one. The adjustment beam has a first rod portion and a second rod portion, and the first rod portion and the second rod portion are indirectly abutted against the bracket. A number of gaskets are provided at the portions where the first rod portion, the second rod portion are abutted against the bracket. In this way, the position of the bracket in the horizontal direction can be adjusted by adjusting the number of gaskets, thereby compensating for the machining error of the seat body.

[0011] Optionally, one of the support portions is provided with a first positioning member, and the other support portion is provided with a second positioning member; one of the first positioning member and the second positioning member forms a non-rotating fit with the seat body, thereby further improving the positioning accuracy between the support portion and the seat body and preventing the seat body from shifting relative to the support portion during operation.

[0012] Optionally, one of the first positioning member and the second positioning member is a circular pin, and the other is a diamond pin. In this embodiment, the precise positioning of the workpiece is achieved by the "one plane and two pins" method, and at the same time, the diamond pin allows a certain degree of floating of the base to adapt to the positioning error, thereby achieving a comprehensive restriction on the six degrees of freedom of the workpiece.

[0013] Optionally, it further includes a locking portion. The locking portion is an elbow rod type mechanical clamping device, and the locking portion includes a locking member provided on the support portion and a locking groove provided on the seat body. By means of the adaptation between the locking member and the locking groove, the seat body can be fixed to the support portion, thereby preventing the position of the fixture assembly from shifting during the machining process.

[0014] Optionally, the locking member is provided on a side where the two supporting parts are away from each other. This can facilitate the operator to lock the seat body and the supporting part outside the fixture switching component.

[0015] Optionally, at least two locking members are provided on each of the supporting parts, and the locking members located on the same supporting part are spaced along the extending direction of the spacing part. In this way, at least two locking positions can be formed for each short side of the seat body, and at the same time, the space on one side of the long side of the seat body will not be occupied, avoiding interference with the stop part and the lifting device.

[0016] Optionally, it further includes a fixing member and a locking channel. The locking channel extends in the height direction and penetrates through the supporting part and the seat body. The locking channel has a socket, and the socket is located on the side walls of the supporting part and the seat body; the fixing member includes a connecting rod and two connecting parts provided on the connecting rod. The connecting rod can enter the locking channel from the socket, and the two connecting parts are located outside the supporting part and the seat body and are used to clamp the seat body and the supporting part in the height direction. In this way, the connection strength between the seat body and the supporting part can be further ensured.

Detailed implementation manners

[0025] The present utility model provides a fixture switching assembly 100. By improving the structure of the fixture switching assembly 100, the rapid switching of fixtures is facilitated.

[0026] In order to enable those skilled in the art to better understand the solution of the present utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific implementation manners.

[0027] Relative terms such as "first" and "second" are only used to distinguish one component with the same name from another, and do not necessarily require or imply any such actual relationship or order between these components.

[0028] Please refer to Figures 1-4 , Figure 1 which is a schematic diagram of the state after the fixture switching device is connected to the fixture assembly 200 in an embodiment of the present utility model; Figure 2 which is an axonometric view of the fixture switching device in an embodiment of the present utility model; Figure 3 which is a top view of the fixture assembly 200 in an embodiment of the present utility model; Figure 4 which is Figure 3 the bottom view of

[0029] As Figures 1 to 3 shown, the present application provides a fixture switching assembly 100. The fixture switching assembly 100 includes a switching device 101 and a lifting device (not shown in the figure). The lifting device can be a forklift or other tooling that can lift the fixture assembly 200 from the ground. The lifting device is used to place the fixture assembly 200 on the switching device 101. The fixture assembly 200 includes a fixture body and a base body 201 that supports the fixture; different fixture assemblies 200 are used to adapt to different workpieces to be processed (not shown in the figure). When welding different workpieces to be processed, only need to use the lifting device to place the corresponding fixture assembly 200 on the switching device 101, and after assembling and fixing the fixture assembly 200 with the switching device 101, the welding operation can be performed on the workpiece to be welded.

[0030] Specifically, referring to Figure 1And Figure 2 , the switching device 101 includes two supporting parts 1 arranged oppositely. The supporting parts 1 are used to support the fixture assembly 200. There is a spacing part 1a between the two supporting parts 1. The lifting device can enter the spacing part 1a from one end of the spacing part 1a. A stop part 4 is also arranged in the spacing part 1a. The stop part 4 directly or indirectly stops the lifting device in the extending direction of the spacing part 1a. That is to say, in the direction in which the lifting device enters the spacing part 1a (such as the entry direction in Figure 2 ), the stop part 4 directly or indirectly stops the lifting device on the front side of the entry direction. It can directly form a stop with the lifting device or indirectly form a stop with the lifting device by stopping the fixture assembly 200. The stop part 4 can be slidably matched with the fixture assembly 200 in the height direction.

[0031] In this embodiment, please also refer to Figure 4 . The spacing part 1a provides space for the movement of the lifting device. Taking the lifting device as a forklift as an example, a frame structure 13 adapted to the forklift is arranged at the bottom of the seat body 201 of the fixture assembly 200. The insertion rod of the forklift can be inserted into the frame structure 13 to drive the fixture assembly 200 to move. When the lifting device places the fixture assembly 200 on the supporting part 1, the lifting device first lifts the fixture assembly 200 to a set height. At this time, the height of the fixture assembly 200 from the ground is greater than the height of the supporting part 1 from the ground; then the lifting device enters the spacing part 1a in the extending direction of the spacing part 1a ( Figure 2 the entry direction in

[0032] until it forms a stop with the stop part 4. At this time, the fixture assembly 200 can be opposite to the supporting part 1 in the height direction. Then, the lifting device drives the fixture assembly 200 to descend until the seat body 201 presses against the upper surface of the supporting part 1. In this process, the fixture assembly 200 and the stop part 4 form a sliding fit in the height direction, and the stop part 4 plays a guiding role. Figure 2 the entry direction in

[0033] By adopting the fixture switching component 100 in the present application, the fixture component 200 can be quickly switched through the cooperation between the lifting device and the switching device 101. During the switching process, the fixture component 200 is blocked by the blocking portion 4, and at the same time, in the height direction, it forms a sliding fit with the fixture component 200 to position the fixture component 200, ensuring the accuracy of the connection position between the fixture component 200 and the support portion 1. Thus, it can be ensured that each time the fixture component 200 is replaced, the new fixture component 200 can be accurately placed at the predetermined position of the support portion 1; this not only improves the assembly accuracy but also avoids machining errors caused by inaccurate positioning; compared with the traditional fixture switching device 101, it simplifies the structure and improves the switching efficiency of the fixture component 200.

[0034] In a specific embodiment, please continue to refer to Figure 1 and Figure 2 The fixture switching component 100 includes a frame 8, and the frame 8 is used to support the aforementioned support portion 1 and the remaining components of the fixture switching component 100. In this embodiment, the blocking portion 4 includes at least two guide rods 41, and the guide rods 41 are fixedly connected to the frame 8, and the two guide rods 41 are arranged at intervals along the distribution direction of the support portion 1; combined with Figure 3 the shown content, the fixture switching component 100 further includes an adapting portion, and the adapting portion can be arranged on the seat body 201, and each adapting portion is in rolling fit with the corresponding guide rod 41.

[0035] Specifically, the seat body 201 has a rectangular structure with a long side direction and a short side direction. The distribution direction of the two support portions 1 is parallel to the long side direction, and the extending direction of the spacing portion 1a is parallel to the short side direction. The two guide rods 41 are distributed along the long side direction of the seat body 201. When the fixture component 200 moves forward in its short side direction, its long side abuts against the guide rods 41 and forms a sliding fit with the guide rods 41.

[0036] In this embodiment, by setting at least two guide rods 41, the seat body 201 can be accurately positioned to avoid misalignment of the seat body 201 during a certain process; in addition, by the way that the adapting portion arranged on the seat body 201 is in sliding fit with the guide rods 41, the friction between the adapting portion and the guide rods 41 can be significantly reduced, avoiding wear of the guide rods 41 during long-term use and reducing the positioning accuracy.

[0037] In a specific implementation, the adapting portion includes a bearing 11 and a bracket 10 connected to the seat body 201. The inner ring of the bearing 11 is fixedly connected to the bracket 10 through a pin shaft, and the outer ring of the bearing 11 contacts the guide rod 41; thus, it can form a rolling fit between the outer ring of the bearing 11 and the guide rod 41 to avoid wear on the guide rod 41.

[0038] AsFigure 1 and Figure 3 As shown in Figure 1 and Figure 3 , the fixture switching assembly 100 further includes an adjusting beam 14. The adjusting beam 14 has an L-shaped structure and is disposed on the seat body 201. The adjusting beam 14 corresponds to each bracket 10 one by one. The adjusting beam 14 has a first rod portion and a second rod portion. The first rod portion is perpendicular to the second rod portion. The first rod portion is parallel to the long side direction of the seat body 201, and the second rod portion is parallel to the short side direction of the seat body 201. The first rod portion and the second rod portion are indirectly abutted against the bracket 10. A plurality of gaskets are provided at the portions where the first rod portion, the second rod portion are abutted against the bracket 10. In this way, the position of the bracket 10 in the horizontal direction can be adjusted by adjusting the number of gaskets, thereby compensating for the machining error of the seat body 201.

[0039] Optionally, each guide rod 41 has an arc surface section 42. The arc surface section 42 extends in the height direction. The position where the outer ring of each bearing 11 contacts the guide rod 41 is located at the arc surface section 42. By providing the arc surface section 42, the portion where the outer ring of the bearing 11 abuts against the arc surface section 42 is in line contact, thereby minimizing the contact area between the guide rod 41 and the mating portion to further avoid the wear of the guide rod 41.

[0040] In order to further improve the positioning accuracy between the support portion 1 and the seat body 201 and avoid the position deviation of the seat body 201 relative to the support portion 1 during the operation, in some other embodiments of the present application, one support portion 1 is provided with a first positioning member 21, and the other support portion 1 is provided with a second positioning member 31; one of the first positioning member 21 and the second positioning member 31 forms a non-rotating fit with the seat body 201.

[0041] Specifically, the first positioning member 21 and the second positioning member 31 are fixedly connected to the support portion 1 by bolts. A groove is provided on the upper surface of the support portion 1 (i.e., the surface that abuts against the seat body 201). The positioning ends of the first positioning member 21 and the second positioning member 31 extend out of the groove and protrude beyond the upper surface of the support portion 1 in the height direction. The lower surface of the seat body 201 is provided with a first positioning groove 22 and a second positioning groove 32 that are adapted to the first positioning member 21 and the second positioning member 31. When the seat body 201 is pressed against the support portion 1, the positioning end of the first positioning member 21 is embedded in the corresponding first positioning groove 22, and the positioning end of the second positioning member 31 is embedded in the corresponding second positioning groove 32. By forming a non-rotating fit between at least one positioning member and the seat body 201, the occurrence of over-positioning is avoided.

[0042] In a specific example, one of the first positioning member 21 and the second positioning member 31 is a round pin, and the other is a diamond pin. In this embodiment, the precise positioning of the workpiece is achieved by the method of "one plane and two pins", and at the same time, the diamond pin allows a certain floating of the base to adapt to the positioning error, thereby achieving a comprehensive restriction on the six degrees of freedom of the workpiece.

[0043] In some other embodiments, in combination with Figures 1-3 , the fixture switching assembly 100 further includes a locking portion 6. The locking portion 6 includes a locking member 7 provided on the support portion 1 and a locking groove 12 provided on the seat body 201. Specifically, the toggle-type mechanical clamping device is, for example, a quick clamp. The quick clamp is based on the principle of a double-rocker mechanism in a planar four-bar mechanism, and in particular, utilizes the dead-point clamping principle in mechanical mechanics to lock the seat body 201 to the support portion 1. By matching the locking member 7 with the locking groove 12, the seat body 201 can be fixed to the support portion 1, thereby preventing the position of the fixture assembly 200 from shifting during the machining process.

[0044] In this embodiment, for the convenience of operation, the locking member 7 is provided on one side where the two support portions 1 are away from each other; in this way, it is convenient for the operator to lock the seat body 201 to the support portion 1 outside the fixture switching assembly 100.

[0045] In a specific implementation, each support portion 1 is provided with at least two locking members 7, and the locking members 7 located on the same support portion 1 are spaced apart along the extending direction of the spacer portion 1a. In this way, at least two locking positions can be formed for each short side of the seat body 201, and at the same time, the space on the long side of the seat body 201 will not be occupied, avoiding interference with the stop portion 4 and the lifting device. Optionally, the two locking members 7 are used to lock the position where the short side and the long side of the seat body 201 are connected, so as to enhance the locking strength.

[0046] In some other embodiments, in order to further lock the seat body 201 to the support portion 1, the fixture switching assembly 100 further includes a fixing member 5 and a locking channel 9a. The locking channel 9a extends in the height direction and penetrates through the support portion 1 and the seat body 201. The locking channel 9a has a socket, and the socket is located on the side walls of the support portion 1 and the seat body 201; specifically, corresponding U-shaped grooves 9 are respectively cut on the support portion 1 and the seat body 201 by cutting as the aforementioned locking channel 9a. The U-shaped groove 9 located on the seat body 201 is provided on the long side of the seat body 201 and is located at the part where the seat body 201 contacts the corresponding support portion 1; at least one U-shaped groove 9 is provided for each part, and it can also be two or more. The U-shaped groove 9 penetrates through the seat body 201 and the support portion 1 in the height direction. In the horizontal direction, sockets are formed on the side walls of the seat body 201 and the support portion 1, and the sockets are used to insert the fixing member 5.

[0047] The fixing member 5 includes a connecting rod 51 and two connecting parts 52 provided on the connecting rod 51. The connecting rod 51 can enter the locking channel 9a through the socket. The two connecting parts 52 are located outside the supporting part 1 and the seat body 201 and are used to clamp the seat body 201 and the supporting part in the height direction. One of the two connecting parts 52 is provided at the top end of the connecting rod 51 and is located on the upper surface of the seat body 201 away from the supporting part 1. The other (not shown in the figure) is threadedly connected to the other end of the connecting rod 51 and is located on the lower surface of the supporting part 1 away from the seat body 201. The size of the connecting part 52 is larger than the cross-sectional size of the U-shaped groove 9. When locking the base and the supporting part 1, the connecting part 52 is rotated so that the two connecting parts 52 clamp the seat body 201 and the supporting part 1 in the height direction. In this way, the connection strength between the seat body 201 and the supporting part 1 can be further ensured.

[0048] In this article, specific examples are used to elaborate on the principle and implementation mode of the present utility model. The description of the above embodiments is only used to help understand the core idea of the present utility model. It should be pointed out that for those of ordinary skill in the art of this technology, without departing from the principle of the present utility model, several improvements and modifications can be made to the present utility model, and these improvements and modifications also fall within the protection scope of the claims of the present utility model.
