Description
Technical Field
[0001] The present application relates to the technical field of mechanical parts processing, and in particular to a fixture for mechanical parts processing. Background Art
[0002] A fixture is a device used to fix the workpiece in the mechanical manufacturing process so that it occupies the correct position for construction or inspection. In a broad sense, any device used to quickly, conveniently and safely install the workpiece in any process can be called a fixture. A fixture usually consists of a positioning element and a clamping device.
[0003] However, firstly, the inventor believes that the scope of use of the existing clamps for processing mechanical parts is too limited. Since different parts have different sizes and do not have an adjustable centering clamping mechanism, it is not convenient to clamp parts of different specifications well, which reduces the scope of use of the clamp structure; secondly, since different positions on the parts need to be processed when processing the parts, the parts need to be removed and clamped again when the parts are changed. This operation method is more cumbersome and does not have a steering mechanism, which makes it inconvenient to quickly change the direction of the parts clamped by the clamp, reducing the convenience of using the clamp. Utility Model Content
[0004] The purpose of the present application is to provide a fixture for machining mechanical parts, so as to improve the problem that the existing fixture structure is not convenient for clamping parts of different specifications well and is not convenient for quickly changing the direction of the parts clamped by the fixture.
[0005] The mechanical parts processing fixture provided in this application adopts the following technical solution:
[0006] A fixture for machining mechanical parts, comprising a base, inner walls on both sides of the base are commonly connected with partitions, the interior of the partitions and the lower inner wall of the base are commonly provided with a steering mechanism, the top end of the steering mechanism is fixedly connected with a vertical shell, the top end of the vertical shell is fixedly connected with a placing table, the top end of the placing table and the interior of the vertical shell are commonly provided with a centering clamping mechanism, the centering clamping mechanism comprises a connecting seat, the top end of the connecting seat is fixedly connected to the upper inner wall of the vertical shell, the bottom end of the connecting seat is fixedly connected with a first motor, and the output of the first motor The output end is fixedly connected with a screw rod, a movable plate is sleeved on the outer surface of the screw rod, and a long rod is fixedly connected to the outer surface of the movable plate, both ends of the vertical shell are provided with limit grooves for matching with two long rods, and one end of the two long rods respectively passes through the two limit grooves and are fixedly connected with a first hinge seat, the inner walls of the two sides of the two first hinge seats are hinged with connecting plates, the two ends of the two connecting plates are hinged with second hinge seats, and the upper inner walls of the two second hinge seats are slidably connected to the bottom end of the placing table, and one end of the two second hinge seats is fixedly connected with a clamping plate.
[0007] By adopting the above technical scheme, the parts to be clamped are first placed on the placement table, and then the first motor is started through the centering clamping mechanism. The output end of the first motor drives the screw to rotate, and the rotation of the screw drives the movable plate to move downward. The downward movement of the movable plate drives the two long rods to move downward at the same time. At the same time, the limit groove serves to facilitate the guiding and limiting of the two long rods when they move. The movement of the two long rods drives the two first hinge seats to move downward respectively. The downward movement of the two first hinge seats is used in conjunction with the second hinge seat through the connecting plate so that the two clamping plates move toward the middle to quickly clamp the parts. When the part clamped by the fixture needs to be turned, the part can be turned through the steering mechanism, thereby improving the convenience of using the fixture structure.
[0008] The top end of the support seat is fixedly connected to the lower inner wall of the base, the top end of the support seat is fixedly connected to the second motor, the output end of the second motor is fixedly connected to the first sprocket, and the top end of the first sprocket is fixedly connected to the first round rod, the top end of the first round rod is fixedly connected to the first gear, the lower inner wall of the base is rotatably connected to the second round rod, and the outer surface of the second round rod is fixedly sleeved with a second sprocket used in conjunction with the first sprocket, the outer surfaces of the first sprocket and the second sprocket are jointly sleeved with a chain, the top end of the second round rod is fixedly connected to a second gear used in conjunction with the first gear, and the outer surfaces of the first gear and the second gear are jointly meshed with a gear ring, the inner wall of the gear ring is fixedly connected to a support column, the top end of the support column passes through the bottom end of the partition and is fixedly connected to the circular plate, and the bottom end of the vertical shell passes through the top end of the partition and is fixedly connected to the top end of the circular plate.
[0009] By adopting the above technical solution, the second motor is started, and the output end of the second motor drives the first sprocket to rotate. The rotation of the first sprocket causes the second sprocket to rotate simultaneously through the chain. The rotation of the second sprocket drives the second round rod to rotate. The rotation of the first sprocket drives the first gear to rotate through the first round rod. The second round rod drives the second gear to rotate. The first gear and the second gear rotate in the same direction at the same time and drive the gear ring to rotate together. The rotation of the gear ring drives the support column to rotate. The rotation of the support column drives the vertical shell to rotate through the circular plate. The rotation of the vertical shell causes the parts clamped by the fixture to turn quickly, thereby improving the efficiency of the fixture.
[0010] Optionally, two mounting plates are fixedly connected to both ends of the base, and mounting holes are provided at the top ends of the four mounting plates.

[0018] Optionally, a positioning groove for cooperating with the circular plate is provided inside the partition, and the outer surface of the circular plate is rotatably connected to the inner wall of the positioning groove.
[0019] By adopting the above technical solution, the positioning groove is used in conjunction with the circular plate to facilitate the positioning of the circular plate when it rotates.
[0020] Optionally, the first sprocket and the second sprocket are flush with each other in height, and the first gear and the second gear are flush with each other in height.
[0021] By adopting the above technical solution, it is convenient for the chain to cooperate with the first sprocket and the second sprocket, so that when the first sprocket rotates, the second sprocket also rotates in the same direction.
