Description

Technical Field

[0001] This utility model belongs to the field of camshaft manufacturing, and in particular relates to a clamping and fixing device for camshaft manufacturing. Background Technology

[0002] The clamping and fixing device in camshaft production is mainly used to firmly clamp and fix the camshaft during machining or assembly to ensure its precise positioning, so as to achieve high-precision machining, measurement or inspection.

[0003] According to a public disclosure (CN 210499353 U), a clamping and fixing device for camshaft machining includes columns, a mounting plate, and a base. Two columns are provided, and a mounting plate is fixedly connected between the upper parts of the two columns. A hydraulic cylinder is fixedly installed at the top center of the mounting plate. Guide sleeves are fixedly installed on both sides of the mounting plate, and guide rods are slidably installed inside each guide sleeve. A support plate is fixedly connected to the bottom end of each guide rod. A clamping and fixing mechanism is provided on the upper surface of the base. This invention achieves drilling of the camshaft on the positioning seat through the coordinated use of the hydraulic cylinder, guide rods, guide sleeves, support plate, motor, mounting plate, through hole, bolts, threaded sleeves, and drill bit. When the end of the hydraulic cylinder moves downward, it drives the support plate downward, causing the clamping block to contact the upper surface of the positioning seat, thus fixing the camshaft. Further activation of the motor then completes the drilling of the camshaft.

[0004] The aforementioned application uses a column, a mounting plate, and a base. There are two columns, and the mounting plate assembly is fixedly connected between the top of the two columns. This makes it impossible to clean up the waste generated during processing, which may cause the waste to fly up due to the impact force during processing and obstruct the view. Therefore, we propose a clamping and fixing device for camshaft production. Utility Model Content

[0005] The purpose of this invention is to provide a clamping and fixing device for camshaft production. Through the rotation of a bidirectional threaded rod and the interaction of gears, racks, support bars, brush plates, and bristles within the cleaning device, the clockwise rotation of the bidirectional threaded rod drives the gears to rotate clockwise. When the gears rotate clockwise, they push the rack forward, which in turn moves the support bar forward, which in turn moves the brush plate forward, and finally, the brush bristles move forward. This achieves the goal of using the movement of the brush bristles to clean up waste material on the worktable. Furthermore, the forward movement of the brush bristles pushes the waste material through a channel into a waste bin, thus solving existing problems.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model is a clamping and fixing device for camshaft production, including a worktable, a support leg fixedly connected to the bottom of the worktable, a camshaft placement frame fixedly connected to the top of the worktable, and a clamping device provided on the top of the worktable.

[0008] The clamping device includes a motor, the bottom of which is fixedly connected to the top of the worktable. The output shaft of the motor is fixedly connected to a bidirectional threaded rod. A threaded sleeve is threadedly connected to the circumferential surface of the bidirectional threaded rod. A U-shaped connecting strip is fixedly connected to the circumferential surface of the threaded sleeve. A push block is fixedly connected to the bottom of the U-shaped connecting strip. A first clamping plate is slidably connected to the top of the worktable. A first force-bearing plate is fixedly connected to the top of the worktable. A tension spring is fixedly connected to the back side of the first force-bearing plate. The end of the tension spring away from the first force-bearing plate is fixedly connected to the front side of the first clamping plate.

[0009] Furthermore, a second clamping plate is slidably connected to the top of the worktable, and a second force-bearing plate is fixedly connected to the top of the worktable. A second tension spring is fixedly connected to the back side of the second force-bearing plate. The end of the second tension spring away from the second force-bearing plate is fixedly connected to the front side of the second clamping plate. The function of the second clamping plate is to cooperate with the first clamping plate to clamp the camshaft. The function of the second tension spring is to allow the second clamping plate to reset when the push block stops pushing the second clamping plate.

[0010] Furthermore, a limiting rod is fixedly connected to the side of the motor. The circumferential surface of the limiting rod penetrates the side of the threaded sleeve, and the circumferential surface of the limiting rod is slidably connected to the inner wall of the threaded sleeve. The function of the limiting rod is to restrict the displacement trajectory of the threaded sleeve.

[0011] Furthermore, the number of the threaded sleeve, U-shaped connecting strip, push block, first clamping plate, first force plate, tension spring one, second clamping plate, second force plate, and tension spring two are each set to two, and they are symmetrical to each other along the vertical central axis of the worktable. The sides of the first clamping plate and the second clamping plate are located on the displacement trajectory of the push block. The purpose of setting the number of the threaded sleeve, U-shaped connecting strip, push block, first clamping plate, first force plate, tension spring one, second clamping plate, second force plate, and tension spring two to two, and symmetrical to each other along the vertical central axis of the worktable, is to better clamp the camshaft. The purpose of the sides of the first clamping plate and the second clamping plate being located on the displacement trajectory of the push block is to push the first clamping plate and the second clamping plate when the push block moves.

[0012] Furthermore, a cleaning device is provided on the top of the workbench. The cleaning device includes a gear, the side of which is fixedly connected to the circumferential surface of the bidirectional threaded rod. A rack is slidably connected to the top of the workbench. A support bar is fixedly connected to the front side of the rack. A brush plate is fixedly connected to the top of the support bar. Brush bristles are fixedly connected to the bottom of the brush plate. The function of the brush bristles is to clean the waste generated during processing on the workbench.

[0013] Furthermore, a through groove is provided on the top of the workbench, and a waste bin is slidably connected to the bottom of the workbench. The waste bin is used to collect the waste material cleaned by the brush bristles.

[0014] Furthermore, the circumferential surface of the gear meshes with the top of the rack, and the bottom of the through groove is located above the waste bin. The meshing of the circumferential surface of the gear with the top of the rack is to push the rack to move when the gear rotates. The bottom of the through groove is located above the waste bin so that waste can enter the waste bin through the through groove.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model achieves the following: the rotation of the motor output shaft cooperates with the components inside the clamping device, such as the bidirectional threaded rod, threaded sleeve, U-shaped connecting strip, push block, first clamping plate, and second clamping plate. When the bidirectional threaded rod reverses, it drives the two threaded sleeves to separate to both sides. When the threaded sleeves separate to both sides, the push block is driven to separate to both sides through the U-shaped connecting strip. This results in the first and second clamping plates being reset by the tension springs 1 and 2 due to the loss of the push force from the push block, thus clamping the camshaft placed on the camshaft mounting bracket.

[0017] 2. This utility model utilizes the interaction between the rotation of the bidirectional threaded rod and the internal components of the cleaning device, such as gears, racks, support bars, brush plates, and bristles. When the bidirectional threaded rod rotates clockwise, it drives the gears to rotate clockwise. When the gears rotate clockwise, they push the rack forward. When the rack moves forward, it drives the support bar forward. When the support bar moves forward, it drives the brush plate forward. When the brush plate moves forward, it drives the bristles forward. This achieves the goal of using the movement of the bristles to clean the waste material on the worktable, allowing the bristles to push the waste material through the channel into the waste bin.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0035] A specific application of this embodiment is as follows: First, when the camshaft needs to be machined, the clamping device 4 can be used to clamp the camshaft. The motor 41 is started first. When the output shaft of the motor 41 rotates, it drives the bidirectional threaded rod 42 to rotate. When the bidirectional threaded rod 42 rotates, it drives the two threaded sleeves 43 to move towards the center. When the threaded sleeves 43 move towards the center, they drive the U-shaped connecting strip 44 to move towards the center. When the U-shaped connecting strip 44 moves towards the center, it drives the push block 45 to move towards the center. When the push block 45 moves towards the center, it pushes the first clamping plate 46 and the second clamping plate 49 to separate to both sides. After the camshaft is separated to both sides, it is placed on the camshaft mounting bracket 3. Then, the reverse motor 41 is reversed, so that the output shaft of the motor 41 drives the bidirectional threaded rod 42 to reverse. When the bidirectional threaded rod 42 reverses, it will drive the two threaded sleeves 43 to separate to both sides. When the threaded sleeves 43 separate to both sides, they will drive the push block 45 to separate to both sides through the U-shaped connecting strip 44. Then, the first clamping plate 46 and the second clamping plate 49 will be reset by the tension spring 48 and the tension spring 411 because they lose the pushing force of the push block 45. After the first clamping plate 46 and the second clamping plate 49 are reset, the camshaft placed on the camshaft mounting bracket 3 will be clamped.

[0036] The rotation of the bidirectional threaded rod 42 drives the cleaning device 5. After the camshaft is processed, the cleaning device 5 can be used to clean up the waste generated on the worktable 1. When the bidirectional threaded rod 42 rotates clockwise, it drives the gear 51 to rotate clockwise. When the gear 51 rotates clockwise, it pushes the rack 52 to move forward. When the rack 52 moves forward, it drives the support bar 53 to move forward. When the support bar 53 moves forward, it drives the brush plate 54 to move forward. When the brush plate 54 moves forward, it drives the bristles 55 to move forward, thereby cleaning up the waste generated on the worktable 1. Then, when the bristles 55 move forward, they push the waste on the worktable 1 through the through groove 56 into the waste bin 57.
