Description

Technical Field

[0001] The utility model relates to the technical field of drill jigs, in particular to a general tooling jig for precision part drill jigs. Background Technique

[0002] A drill jig is a machine tool fixture used to guide a cutting tool to drill (see drilling) or ream (see reaming) holes in a workpiece. After retrieval, the patent with the publication number CN218135173U discloses a general tooling jig for precision part drill jigs, including a base. At the center position of the top of the base, a placement table is installed. At the center position of the surface of the placement table, a bearing is provided. At the rear end of the top of the base, an L-shaped bracket is installed. Its structure is reasonable. The utility model installs the tooling jig mechanism on the placement table by providing a screw rod and the tooling jig mechanism, places the precision part on the placement table, rotates the handwheel on the tooling jig mechanism to move two groups of L-shaped clamps inward to clamp the precision part placed on the placement table. After the clamping is completed, adjust the distance between the screw rod and the precision part, rotate the screw rod until the rubber seat presses against the top of the precision part, and cooperate with the positioning drilling on the L-shaped bracket, so as to perform drilling operations on the precision part, effectively improving the stability of the general tooling jig for precision part drill jigs. However, when this drill jig is in use, it is necessary to clamp the part, and the position of the clamping device is relatively high. When the part is clamped, the part is in a suspended state. Therefore, when drilling, due to the downward pressure of the drill bit, the clamped part is likely to slowly move downward between the side walls of the clamping device, resulting in the position movement of the part. Content of the Utility Model

[0003] Aiming at the deficiencies of the prior art, the utility model provides a general tooling jig for precision part drill jigs, which solves the problem that when the drill jig is in use, it is necessary to clamp the part, and the position of the clamping device is relatively high. When the part is clamped, the part is in a suspended state. Therefore, when drilling, due to the downward pressure of the drill bit, the clamped part is likely to slowly move downward between the side walls of the clamping device, resulting in the position movement of the part.

[0004] To achieve the above purposes, the utility model is realized through the following technical solutions: A general tooling jig for precision part drill jigs includes a base and a support seat. Inside the bottom surface of the base, a T-shaped groove is provided. Inside the T-shaped groove, a T-shaped seat is slidably connected. Inside the T-shaped seat, a cylinder is fixedly installed. On both sides inside the T-shaped groove, screw rods are symmetrically rotatably connected. The two ends of the T-shaped seat are respectively threadedly sleeved on the rod walls of the screw rods. On the right end of the base, reciprocating motors are symmetrically fixedly installed. The output shafts of the reciprocating motors respectively pass through the right side wall of the base and are fixedly connected to the right ends of the screw rods. The bottom of the support seat is fixedly connected to the output shaft of the cylinder.

[0005] Preferably, a support frame is fixedly installed on the top surface of the base. The support frame is U-shaped, and L-shaped fixing plates are symmetrically and fixedly installed on the side walls at both ends of the support frame. Limiting rods are symmetrically and fixedly installed between the two L-shaped fixing plates. Clamping plates are symmetrically sleeved on the rod walls of the limiting rods. Screws are rotatably connected to the inner parts of the side walls of both L-shaped fixing plates. Threaded tubes are threadedly connected to the rod walls of the screws. Handwheels are rotatably connected to the inner parts of the side walls of the L-shaped fixing plates. The parts where the handwheels are connected to the L-shaped fixing plates are fixedly connected to the screws. The ends of the threaded tubes are fixedly connected to the side walls of the clamping plates, so that the parts placed can be conveniently clamped.

[0006] Preferably, positioning holes are arranged inside the top surface of the support frame. A positioning tube is arranged below the positioning holes. The positioning tube is arranged between the two limiting rods. Support rods are symmetrically and fixedly installed on the side walls on both sides of the positioning tube. The ends of the support rods are fixedly connected to the side walls of the limiting rods, so as to facilitate the protection of the drill bit for drilling and the positioning of the drilling position.

[0007] Preferably, the bottom surface of the positioning tube is at the same level as the bottom of the limiting rod, so as to prevent the positioning tube from directly pressing against the parts.

[0008] The utility model provides a general tooling fixture for precision part drilling jigs. It has the following beneficial effects:

[0009] 1. When using the general tooling fixture for precision part drilling jigs, through the cooperation between the cylinder and the support base, it can move according to the position of the part. Open the cylinder to make the support base move upward, so that the support base can support the clamped part and prevent the position of the part from falling off during the drilling work.

[0010] 2. When using the general tooling fixture for precision part drilling jigs, through the clamping plates separately arranged on both sides of the device, when drilling at different positions, the clamping plate on one side can be separately controlled to move, which can change the position of the part and clamp it at the same time.
