Description

Technical Field

[0001] The utility model relates to the technical field of cam follower processing, and particularly relates to a positioning tooling for small hole machining of a cam follower. Background Technique

[0002] A cam follower is a component that directly obtains motion from a cam in a cam mechanism; during its processing operation, a hole needs to be drilled on the side where the slot of the follower is located.

[0003] After the existing positioning tooling for cam followers positions the follower, it is unable to adjust its angle, resulting in the inability to adjust the drilling position of the follower. Since there are certain differences in the drilling positions of some cam followers, the applicability of the tooling is poor, which is not conducive to the actual requirements of production and processing. Therefore, it is necessary to propose a positioning tooling for small hole machining of a cam follower to solve the above problems. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a positioning tooling for small hole machining of a cam follower, which has the effects of adjustable drilling position and strong applicability.

[0005] The above technical purpose of the utility model is achieved through the following technical solutions: A positioning tooling for small hole machining of a cam follower includes a processing table and a positioning tooling installed on the processing table. The positioning tooling is provided with fixing screws and positioning cylinders that respectively fix both ends of the follower. A drilling positioning block is arranged at the upper end of the positioning tooling, and an adjusting component for adjusting the positioning angle of the follower is arranged on the left side of the positioning tooling. The adjusting component includes a rotating rod that penetrates the positioning tooling and is connected to the fixing screw. A first handle and a positioning member for restricting the rotation of the rotating rod are arranged at the end of the rotating rod away from the fixing screw. A locking member is arranged at the end of the fixing screw, and a connecting rod is installed between the rotating rod and the positioning cylinder.

[0006] By adopting the above technical solutions, one end of the cam follower is placed on the rotating rod, and the other end is placed on the positioning cylinder. The locking member fixes its end to the rotating rod. By controlling the rotation of the rotating rod through the first handle, under the drive of the connecting rod, the inclination angle of the fixed follower can be adjusted, and then its position is fixed by the positioning member, so as to meet the drilling of different positions of the follower and make it more applicable.

[0007] The further setting of the utility model is: The locking member includes a fixing nut and a fixing piece arranged on the fixing screw, and the fixing nut is in threaded fit with the fixing screw.

[0008] By adopting the above technical solutions, the nut is rotated to make the fixing piece press one end of the cam follower tightly, so that its end is fixed to the rotating rod.

[0009] The further setting of the present utility model is as follows: The positioning member includes a fixing plate installed on the side of the processing table. An arc-shaped rack is provided on one side of the fixing plate close to the rotating rod. A gear adapted to the arc-shaped rack is provided on the outer side of the rotating rod. A pushing member for moving the arc-shaped rack closer to the gear is also provided on the fixing plate.

[0010] By adopting the above technical solution, after the position of the follower is adjusted by the rotating rod, the pushing member moves the arc-shaped rack closer to the gear to clamp the gear, thereby preventing the rotating rod from rotating, so that the cam follower can be fixed firmly, facilitating stable drilling.

[0011] The further setting of the present utility model is as follows: The pushing member includes a rotating lead screw threadedly arranged on the fixing plate and connected to the arc-shaped rack. Both ends of the side of the arc-shaped rack are provided with telescopic rods connecting to the fixing plate.

[0012] By adopting the above technical solution, the rotating lead screw is rotated to push the arc-shaped rack. Under the telescopic action of the telescopic rods, the arc-shaped rack slides smoothly.

[0013] The further setting of the present utility model is as follows: A turntable rotatably connected to the positioning tooling is installed on the outer side of the rotating rod. One end of the connecting rod is fixedly connected to the turntable, and the other end is fixedly connected to the positioning cylinder.

[0014] By adopting the above technical solution, when the rotating rod rotates, the turntable on the outer wall rotates, and drives the positioning cylinder to rotate through the connecting rod, thereby stably adjusting the drilling inclination angle of the cam follower.

[0015] The further setting of the present utility model is as follows: The positioning tooling is provided with a limiting groove for the rotation of the positioning cylinder and the connecting rod.

[0016] By adopting the above technical solution, the connecting rod drives the positioning cylinder to rotate, changing the drilling inclination angle of the follower.

[0017] The further setting of the present utility model is as follows: Two threaded columns penetrating the bottom of the positioning tooling are provided on the processing table, and positioning nuts are provided on the threaded columns.

[0018] By adopting the above technical solution, through the cooperation of the threaded columns and the positioning nuts, the positioning tooling can be stably and quickly assembled on the processing table.

[0019] The further setting of the present utility model is as follows: The positioning tooling is provided with an opening for the back-and-forth sliding of the drilling positioning block and an adjusting member for pushing the drilling positioning block to slide.

[0020] By adopting the above technical solution, the adjusting member can push the drilling positioning block to slide left and right, thereby adjusting the drilling position to meet different processing requirements.

[0021] A further setting of the present utility model is that the adjusting member includes an adjusting screw rod rotatably arranged at the upper end of the positioning tooling. One end of the adjusting screw rod passing through to the outside of the positioning tooling is provided with a second handle, and a threaded block threadedly connected to the adjusting screw rod is installed on the side surface of the drilling positioning block.

[0022] By adopting the above technical solution, holding the second handle and rotating the adjusting screw rod can push the threaded block to slide left and right, thereby adjusting the position of the drilling positioning block to meet the drilling at different positions of the follower.

[0023] A further setting of the present utility model is that limiting strips are installed on both the upper and lower sides of the opening, and limiting grooves adapted to the limiting strips are provided at both the upper and lower ends of the threaded block.

[0024] By adopting the above technical solution, when the threaded block slides, the cooperation between the limiting grooves on both sides of it and the limiting strips enables the threaded block to drive the drilling positioning block to slide back and forth more stably.

[0025] The beneficial effects of the present utility model are:

[0026] 1. In the present utility model, one end of the cam follower is placed on the rotating rod, and the other end is placed on the positioning cylinder. The locking member fixes its end to the rotating rod. By controlling the rotation of the rotating rod with the first handle, under the drive of the connecting rod, the inclination angle of the fixed follower can be adjusted, and then its position is fixed by the positioning member, so as to be able to meet the drilling at different positions of the follower and make it more applicable.

[0027] 2. In the present utility model, by holding the second handle and rotating the adjusting screw rod, the threaded block can be pushed to slide left and right, thereby adjusting the position of the drilling positioning block to meet the drilling at different positions of the follower, so as to better meet the actual production and processing requirements.
