Description

Technical Field

[0001] The utility model belongs to the technical field of clamps, and in particular relates to a tooling clamp. Background Art

[0002] The brake master cylinder, also known as the hydraulic brake master cylinder, is a vital component in the automobile braking system. In the design of the brake master cylinder, the piston is one of the key components, responsible for generating and transmitting the necessary braking pressure during the braking process. In order to optimize the performance and efficiency of the brake master cylinder, a dual-chamber design is often used in modern braking systems, which includes a first piston and a second piston.

[0003] The first piston and the second piston usually need to have multiple circular holes circumferentially formed thereon. The circular holes are usually called compensation oil holes and bypass oil holes. These holes are designed to increase the speed of liquid flow and improve the sensitivity and efficiency of braking.

[0004] When drilling multiple circular holes on the first piston and the second piston, it is usually necessary to rotate after drilling one circular hole before drilling the next circular hole. The existing traditional tooling fixture only fixes the first piston or the second piston (hereinafter collectively referred to as the workpiece) when clamping it. When rotation is required, the fixation is usually released, which can easily lead to deviations during the secondary clamping, affecting the drilling accuracy and product quality. Utility Model Content

[0005] The purpose of the utility model is to provide a tooling fixture to solve the above-mentioned technical problems, so as to improve the clamping accuracy of the workpiece after the workpiece is rotated to adjust the drilling position when multiple circular holes are drilled on the side of the workpiece.

[0007] a base, mounted with a support block for supporting a workpiece;

[0008] The clamping mechanism is installed on the base and located on the side of the support block, and includes a first limiting component for radially limiting the workpiece and a fixing component for fixing the workpiece;

[0009] The limiting mechanism is installed on the base and located on the side of the supporting block, and comprises a second limiting component for axial limiting of the workpiece and a rotating component for rotating the workpiece.

[0017] A second pressing plate, mounted at the output end of the second driving member and located above the supporting block;

[0018] The pressing block is installed on a side of the second pressing plate close to the supporting block.

[0019] In the above technical solution, further, the second limiting component includes:

[0020] A third driving member is mounted on the base and is located on a side of the supporting block;

[0021] The baffle is installed at the output end of the third driving member and is located on the side of the supporting block.

[0022] In the above technical solution, further, the second limiting component also includes:

[0023] A stop bar, detachably mounted on the base;

[0024] The height of the stop bar will not affect the workpiece extending out of the side of the support block.

[0025] In the above technical solution, further:

[0026] A slide groove parallel to the axial direction of the workpiece is provided on the base, and bolts are provided along the slide groove on the baffle bar to be slidably connected with the base.

[0035] 1. By setting the clamping mechanism into a fixed component and a first limiting component, when the first round hole is drilled in the workpiece and conversion is required, the fixed component is loosened, the workpiece is limited by the first limiting component, and then the workpiece is rotated.
