Wheel frames are welded at equal intervals on the surface of the worktable, and guide rollers are rotatably connected to the outside of the wheel frames. A clamping assembly is installed on the surface of the worktable. Guide rollers are rotatably connected to the wheel frames welded at equal intervals above the worktable. The car seat bracket to be processed is placed directly on the surface of the guide rollers, with one end of the car seat bracket abutting against a limiting seat. A hydraulic push rod pushes a clamping plate, and the clamping seat clamps and fixes the car seat bracket, allowing for drilling.

[0004] When processing car seats, materials of the same specifications are usually processed in batches. The aforementioned patent clamps the car seat bracket, but it lacks a positioning function. It cannot position materials of the same specifications in the same position during processing, which may lead to misalignment and low processing efficiency. Utility Model Content

[0005] In view of this, the present invention provides a positioning device for processing automotive seat brackets, which solves the problem that the existing clamping mechanism has poor positioning consistency for seat bracket materials of the same specification, cannot ensure that all materials of the same specification are accurately fixed at a unified reference position, and is prone to the problem of materials deviating from the preset processing center, thus resulting in low processing efficiency.

[0006] This utility model is implemented as follows:

[0007] This utility model provides a positioning device for processing car seat brackets, which has two side plates, both of which are fixedly installed on the frame. The side plates are provided with push plates that drive the seat material to move vertically, and the push plates are provided with positioning components that clamp the seat material.

[0008] The push plate has a cross-shaped structure. On the left and right sides of the longitudinal plate of the push plate, there are two sets of moving components that are symmetrically arranged relative to the transverse plate. Each set of moving components has multiple synchronously rotating rollers.

[0009] Based on the above technical solution, the positioning device for processing automobile seat brackets of this utility model can be further improved as follows:

[0010] Furthermore, the positioning component includes a horizontally arranged groove A on the horizontal plate of the push plate and a vertically arranged groove B on the vertical plate, wherein two synchronously moving clamping plates are slidably connected at both groove B and groove A.

[0011] Furthermore, both groove A and groove B are rotatably connected to a bidirectional lead screw, and the clamping plate is fixedly installed on the nut of the bidirectional lead screw via a connecting rod. The bottom wall of the clamping plate is slidably connected along the top wall of the push plate.

[0012] Furthermore, a fixed end of a telescopic cylinder is fixedly installed on the frame, the movable end of the telescopic cylinder extends upward and is fixedly installed on the support plate, and the middle part of the top wall of the support plate and the middle part of the bottom wall of the push plate are fixedly connected by a vertical rod.

[0013] Furthermore, the left and right ends of the roller are rotatably connected to the side plate and the support plate, respectively. The support plate is L-shaped and its bottom wall is fixedly installed on the frame.

[0014] Two sprockets are fixedly installed at the left end of the left-side roller and the right end of the right-side roller.

[0015] Furthermore, a chain is connected to two adjacent sprockets for common transmission, and the chains on the same side are staggered inside and outside;

[0016] A main sprocket is provided between the two sets of moving components distributed longitudinally. The two sprockets that are close to each other and the main sprocket are connected to a main chain for transmission. The two main sprockets are fixedly installed at the left and right ends of the drive shaft, and the drive shaft is rotatably connected to the frame.

[0017] Compared with the prior art, the advantages of the positioning device for processing automobile seat brackets provided by this utility model are:

[0018] By setting a vertically moving push plate, the seat material can be detached from the roller for drilling, avoiding material movement during processing on the roller; by setting a bidirectional lead screw with longitudinal and transverse settings on the push plate, the material to be processed can be positioned in the middle of the push plate, preventing the drilling machine from moving back and forth when processing materials of the same size; by setting sprockets, chains, main sprockets, main chains, and drive shafts, the rollers on the moving components on both sides of the push plate can rotate synchronously with consistent speed and direction.

[0031] Example 1

[0032] like Figure 1-4 As shown, this utility model provides a positioning device for processing car seat brackets, which has two side plates 1, both of which are fixedly installed on the frame 11. The side plates 1 are provided with push plates 2 that drive the seat material to move vertically, and the push plates 2 are provided with positioning components for clamping the seat material.

[0033] The push plate 2 has a cross structure. On both the left and right sides of the longitudinal plate of the push plate 2, there are two sets of moving components that are symmetrically arranged relative to the transverse plate. Each set of moving components has multiple synchronously rotating rollers 41.

[0034] Optionally, in the above technical solution, the positioning component includes a horizontally arranged groove A21 on the horizontal plate of the push plate 2 and a vertically arranged groove B22 on the vertical plate, wherein two synchronously moving clamping plates 23 are slidably connected at both groove B22 and groove A21.

[0035] Optionally, in the above technical solution, a bidirectional lead screw 24 is rotatably connected in both groove A21 and groove B22. A clamping plate 23 is fixedly installed on the nut 25 of the bidirectional lead screw 24 through a connecting rod 26. The bottom wall of the clamping plate 23 is slidably connected along the top wall of the push plate 2.

[0036] Optionally, in the above technical solution, the fixed end of the telescopic cylinder 31 is fixedly installed on the frame 11, the movable end of the telescopic cylinder 31 extends upward and the end is fixedly installed on the support plate 32, and the middle part of the top wall of the support plate 32 and the middle part of the bottom wall of the push plate 2 are fixedly connected by a vertical rod 33.

[0037] Optionally, in the above technical solution, the left and right ends of the roller 41 are rotatably connected to the side plate 1 and the support plate 12 respectively. The support plate 12 is L-shaped and its bottom wall is fixedly installed on the frame 11.

[0038] Two sprockets 42 are fixedly installed on the left end of the left roller 41 and the right end of the right roller 41.

[0039] Optionally, in the above technical solution, two adjacent sprockets 42 are connected by a chain 43 for common transmission, and the chains 43 on the same side are staggered inside and outside;

[0040] A main sprocket 44 is provided between two sets of longitudinally distributed moving components. A main chain 441 is connected to two sprockets 42 and the main sprocket 44 that are close to each other. The two main sprockets 44 are fixedly installed at the left and right ends of the drive shaft 45, which is rotatably connected to the frame 11.

[0041] See Figure 4 In this configuration, two sets of longitudinally distributed moving components are connected to a main chain 441 via two sprockets 42 on the inner sides of two adjacent rollers 41. The outer sprocket 42 (on the same roller 41) corresponding to the sprocket 42 (mentioned earlier) and the outer sprocket 42 on the adjacent roller 41 of the same moving component are connected to a chain 43. Similarly, the inner sprocket 42 (on the same roller 41) corresponding to the sprocket 42 (mentioned earlier) and the inner sprocket 42 on the adjacent roller 41 of the same moving component are connected to a chain 43. This process continues. In the longitudinally distributed moving components, the outer sprocket 42 on the roller 41 furthest from the other moving component is not connected to a chain 43.

[0042] The telescopic cylinder 31 can be selected from existing equipment as needed, and the lifting and lowering of the cylinder can be achieved through existing control elements and controllers such as solenoid valves, PLCs and solenoid valves used to control the lifting and lowering of the cylinder.

[0043] Furthermore, baffles 13 are fixedly installed on both the left and right side walls of the frame 11. Both ends of the drive shaft 45 pass through the baffles 13 and are rotatably connected to the baffles 13 via bearings 130 (wherein, the bearings 130 are bearings with diamond-shaped seats). A motor base 14 is fixedly installed on the left baffle 13, and a drive motor 46 is fixedly installed on the motor base 14. The output shaft of the drive motor 46 extends to the right and is connected to the drive shaft 45.

[0044] Furthermore, when the material is clamped by the clamping plate 23 of the positioning component, it may or may not be in contact with the top wall of the push plate 2. When in contact: the telescopic cylinder 31 moves the push plate 2 up to contact the bottom wall of the material, and the clamping plate 23 clamps the material. When not in contact: the telescopic cylinder 31 moves the push plate 2 up to a certain distance from the bottom wall of the material, and the clamping plate 23 is higher than the roller 41, and the clamping plate 23 clamps the material.

[0045] Among them, the two bidirectional lead screws 24 are staggered vertically (the longitudinally arranged bidirectional lead screw 24 is located above the transversely arranged bidirectional lead screw 24), and the height of the connecting rod 26 on the longitudinal bidirectional lead screw 24 is lower than the height of the connecting rod 26 on the transverse bidirectional lead screw 24. The dimensions of the two bidirectional lead screws 24 and their corresponding nuts 25 are the same.

[0046] Among them, telescopic cylinder 31 is a cylinder with a guide rod; and bidirectional lead screw 24 is a left-right turning ball screw.

[0047] Furthermore, drive motors are fixedly installed on the front and right walls of the push plate 2. The output axis of the drive motor extends backward and to the left and is connected to the bidirectional lead screw 24. The drive motor can rotate forward or backward, and its top wall height does not exceed the clamping plate 23.

[0048] Among them, grooves A21 and B22 are vertical through grooves to prevent waste material from accumulating in the push plate 2 during drilling and affecting the rotation of the bidirectional lead screw 24.

[0049] Working principle:

[0050] When using, place the material to be processed onto the front end of push plate 2 (e.g., Figure 1 (The front end is the feeding point). Start the drive motor 46 to make it drive the transmission shaft 45 to rotate in place. The transmission shaft 45 makes the two main sprockets 44 rotate simultaneously. Under the action of the middle main chain 441, it drives the two sprockets 42 on the same main chain 441 as the main sprockets 44 to rotate. Since the sprockets 42 are connected to the front and rear sprockets 42 through the chain 43, a set of moving components makes the sprockets 42 drive all the rollers 41 to rotate counterclockwise synchronously through the staggered chain 43, so that the material moves backward.

[0051] When the material moves to the push plate 2 (i.e., the distance between the two horizontal clamping plates 23 is the farthest, the distance between the two vertical clamping plates 23 is the farthest, and the material is located in the movable area formed by the four clamping plates 23), the drive motor 46 stops working, and the telescopic cylinder 31 drives the support plate 32 to move upward, so that the top wall of the clamping plate 23 is higher than the roller 41. The two drive motors are started to drive the two bidirectional lead screws 24 set horizontally and vertically to rotate. The two nuts 25 on the bidirectional lead screws 24 move closer to each other synchronously, and the clamping plates 23 move closer to each other through the connecting rod 26, clamping the material in the middle. The telescopic cylinder 31 moves its movable end upward, so that the material leaves the moving component and is processed by the drilling machine.

[0052] After processing is completed, the movable end of the telescopic cylinder 31 retracts, causing the push plate 2 to move down until the material is located on the roller 41 of the moving component and the top wall of the clamping plate 23 is lower than the roller 41. At this time, the drive motor 46 is started again, driving the material to move backward.

[0053] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
