Description

Technical Field

[0001] This utility model belongs to the field of manufacturing, and specifically relates to a flip-type processing fixture. Background Technology

[0002] During product processing, two workpieces need to be welded. The process requires applying spot welding paste to the end of one workpiece first, and then placing the other workpiece on top of the first workpiece to weld the connection. During this process, the opening and closing control of the fixture is difficult, and it is difficult to align the two workpieces during the opening and closing of the fixture, making it difficult to guarantee the welding quality. If the positioning is inaccurate, it will affect the welding quality. Therefore, the existing processing needs to be improved. Utility Model Content

[0003] Purpose of the utility model: In order to overcome the above shortcomings, the purpose of this utility model is to provide a flip-type processing fixture with simple structure, reasonable design and easy production. By setting the flip-type fixture on the turntable, the product clamped in the clamping assembly is flipped by the flip frame, so that the upper and lower workpieces are set relative to the center, which facilitates subsequent welding processing and improves the stability and welding quality of the product welding.

[0004] Technical solution: To achieve the above objectives, this utility model provides a flip-type machining fixture, comprising:

[0005] The product placement seat is equipped with a lifting and positioning mechanism, and a flip-connecting seat is provided on one side of the product placement seat;

[0006] A flipping frame is hinged to a flipping connecting seat via a connecting shaft, and a clamping assembly is provided on the flipping frame. This utility model discloses a flipping processing fixture with a simple structure and reasonable design. By setting a flipping fixture on a turntable, the flipping frame drives the product clamped in the clamping assembly to flip, allowing the upper and lower workpieces to be positioned relative to each other at the center, facilitating subsequent welding processing, improving the stability and quality of product welding, and also effectively increasing product processing efficiency.

[0007] In addition, a tilting drive device is included. This device comprises a tilting mounting base, a sliding block, a slide rail, a rack, and a tilting drive mechanism. The tilting mounting base is installed below the worktable. The sliding block is mounted on the tilting mounting base, and the slide rail is slidably connected to the sliding block. The rack is located on the side of the slide rail away from the sliding block. The tilting drive mechanism is mounted on the frame. A transmission component is located on the side of the slide rail closest to the tilting drive mechanism, and this transmission component cooperates with the tilting drive mechanism. The drive assembly drives the transmission component to rise and fall, thereby causing the slide rail to move the rack to rise and fall. The rise and fall of the rack drives the gear to rotate forward and backward.

[0008] Furthermore, the flipping connecting seat is provided with a set of connecting ears, and a gear is provided on the connecting shaft between the two connecting ears, the gear meshing with the rack. The flipping drive mechanism drives the slide rail to move along the sliding block, and the slide rail moves during the movement of the slide rail, which in turn drives the gear to rotate, thereby causing the flipping frame to flip.

[0009] Preferably, the tilting drive mechanism includes a set of support columns and a tilting drive cam. The tilting drive cam is mounted on the worktable via the support columns and is located below the turntable. The tilting drive cam has a limiting groove for restricting the running trajectory of the transmission component. The limiting groove allows for good control of the running trajectory of the transmission component, facilitating the opening and closing of the tilting frame.

[0010] More preferably, the product placement seat is provided with at least one limiting member. The limiting member can limit the flipping height of the flipping frame and prevent it from flipping excessively.

[0011] Furthermore, the lifting and positioning mechanism includes a bushing, which is disposed on the flip mounting base and the turntable. A lifting column is provided inside the bushing, and a product placement rack is provided on the lifting column.

[0012] Preferably, the product placement rack is provided with grooves for placing workpieces. The grooves can improve the stability of product placement to a certain extent.

[0013] As can be seen from the above technical solution, this utility model has the following beneficial effects:

[0014] 1. The flip-type processing fixture described in this utility model has a simple structure and reasonable design. By setting the flip-type fixture on the turntable, the product clamped in the clamping assembly is flipped by the flipping frame, so that the upper and lower workpieces are set relative to the center, which facilitates subsequent welding processing, improves the stability and welding quality of the product welding, and also effectively improves the product processing efficiency.

[0015] 2. The flipping drive mechanism drives the slide rail to move along the sliding block. During the movement of the slide rail, the rack moves, and during the movement of the rack, the gear rotates, thereby driving the flipping frame to flip. The cooperation between the gear and the rack ensures that the jig opens and closes more smoothly and stably.

[0016] 3. The setting of the limiting component can limit the tilting height of the tilting frame and prevent it from over-tilting.

[0017] 4. The clamping fixture and product placement seat on the flipping frame can effectively improve the stability of the two workpieces, allowing them to be welded better. Attached Figure Description

[0021] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments. Example

[0022] like Figures 1 to 2 The flip-type processing fixture shown includes: a product placement seat 31 and a flip frame 32. The product placement seat 31 is provided with a lifting and positioning mechanism 311, and a flip connecting seat 312 is provided on one side of the product placement seat 31. The flip frame 32 is hinged to the flip connecting seat 312 through a connecting shaft, and a clamping assembly 33 is provided on the flip frame 32.

[0023] It also includes a tilting drive device 34, which comprises a tilting mounting base 341, a sliding block 342, a slide rail 343, a rack 344, and a tilting drive mechanism 345. The tilting mounting base 341 is mounted below the worktable, the sliding block 342 is mounted on the tilting mounting base 341, the slide rail 343 is slidably connected to the sliding block 342, the rack 344 is located on the side of the slide rail 343 away from the sliding block 342, and the tilting drive mechanism 345 is mounted on the frame. A transmission component 346 is provided on the side of the slide rail 343 near the tilting drive mechanism 345, and the transmission component 346 cooperates with the tilting drive mechanism 345. The drive assembly drives the transmission component to rise and fall, thereby allowing the slide rail to drive the rack to rise and fall, and the rise and fall of the rack drives the gear to rotate forward and backward.

[0024] The flip-connector 312 is provided with a set of connecting ears, and a gear 313 is provided on the connecting shaft between the two connecting ears. The gear 313 meshes with the rack 344.

[0025] The flipping drive mechanism 345 includes a set of support columns 3451 and a flipping drive cam 3452. The flipping drive cam 3452 is mounted on the worktable via the support columns 3451 and is located below the turntable. The flipping drive cam 3452 is provided with a limiting groove 3453 for limiting the running trajectory of the transmission component 346. The limiting groove 3453 is located at the highest point of the welding station, and upward tilting limiting grooves and downward tilting limiting grooves are respectively provided on both sides of the highest point to facilitate the entry and exit of the transmission component 346 into and out of the limiting grooves.

[0026] The product placement seat 31 is provided with at least one limiting member 35.

[0027] The lifting and positioning mechanism 311 includes a bushing 3111, which is mounted on the flipping mounting base 341 and the turntable. A lifting column 3112 is provided inside the bushing 3111, and a product placement rack 3113 is mounted on the lifting column 3112. During operation, when the turntable drives the flipping fixture to rotate the product to the welding station, the lifting drive cylinder located below the turntable (such as...) Figure 3 As shown, the lifting column 3112 in the driving lifting and positioning mechanism 311 will rise, and the lifting column 3112 will drive the product to rise, so that it is in contact with the needle above, making it easier for the welding equipment to weld.

[0028] The product placement rack 3113 is provided with a groove for placing workpieces.

[0029] The working principle of the flip-type machining fixture described in this embodiment is as follows:

[0030] The pipe fitting is placed into the groove of the product placement rack 3113. During the rotation of the turntable, the transmission component 346 enters the limiting groove 3453 of the flipping drive cam 3452. When the turntable rotates, the transmission component 346 runs along the downward inclined limiting groove trajectory of the limiting groove 3453. During this process, when the transmission component 346 moves downward along the limiting groove 3453, it will drive the slide rail 343 to move along the sliding block 342. The slide rail 343 drives the rack 344 to move. During the movement of the rack 344, it drives the gear 313 to rotate, thereby driving the flipping frame 32 to flip and open the clamp.

[0031] When the transmission component 346 moves upward along the upward inclined limiting groove of the limiting groove 3453, it will drive the slide rail 343 to move along the sliding block 342. The slide rail 343 drives the rack 344 to move. During the movement of the rack 344, it drives the gear 313 to rotate, thereby driving the flipping frame 32 to flip so that the workpiece held by the clamping component 33 is aligned with the workpiece on the product placement frame 3113. Then, the product can be welded by the welding mechanism (not shown in the figure).

[0032] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements can be made without departing from the principle of the present utility model, and these improvements should also be considered within the protection scope of the present utility model.
