Description

Technical Field

[0001] This utility model relates to the field of parts casting production technology, and in particular to a tool for inspecting the deformation of caliper cutting edges. Background Technology

[0002] Currently, most modern cars are equipped with disc brakes on their front wheels, and some even have disc brakes on all four wheels. These are the components in the car's braking system that are truly responsible for stopping the vehicle. Disc brakes are hydraulically controlled, and their main components include the brake disc, brake caliper, brake pads, and brake lines. Disc brakes are characterized by rapid heat dissipation, light weight, simple construction, and easy adjustment. The brake caliper (or caliper body) is one of the main components of a car's hydraulic disc brake. After processing, it works in conjunction with the brake piston, brake disc, friction pads, and brake bracket. It is the part of the car with the most concentrated stress and the most frequent exposure to varying loads, directly affecting the car's safety performance; therefore, its design standards are extremely stringent.

[0003] Due to the high requirements for the appearance of the castings, no grinding marks are allowed on any part, but the traces of the burrs must be retained, and the burr height should be as uniform as possible, with a requirement of less than 1.0mm. Traditional manual grinding can easily damage the casting body, while robotic grinding can guarantee quality but is inefficient and difficult to meet the requirements of large-scale production. Existing trimming dies can meet customer quality requirements and can also meet large-scale production schedules, but trimming can occasionally cause deformation or minor fractures, which cannot be directly identified by humans, resulting in high external quality risks.

[0004] In conclusion, it is necessary to design a tool for inspecting the deformation of caliper cutting edges to solve the above problems. Utility Model Content

[0005] The technical problem to be solved by this utility model is that, in the case of caliper cutting edge deformation or minor fracture that may occur, but cannot be directly identified by humans and has a high external quality risk, a new inspection tool for caliper cutting edge deformation is proposed.

[0006] To solve the above-mentioned technical problems, this utility model provides a caliper cutting deformation inspection tool, including: an angle adjuster and a tool platform. The angle adjuster is fixedly installed on the upper part of the bottom side of the tool platform. The upper surface of the tool platform is respectively provided with two vertical cylinder head auxiliary positioning blocks, two pairs of vertical inspection lug positioning blocks, a casting vertical placement platform block, a vertical inspection arc back auxiliary positioning block, two pairs of parallel inspection lug positioning blocks, two parallel inspection riser diameter positioning blocks, two casting parallel placement platform blocks, two casting vertical placement blocks, and a casting parallel placement block. The two vertical cylinder head auxiliary positioning blocks are located on the upper part of the upper surface of the tool platform, and the two pairs of vertical inspection lug positioning blocks are fixedly installed on the upper side of the bottom side of the tool platform. Positioning blocks are located on both sides below the vertical detection cylinder head auxiliary positioning block. The casting vertical placement platform block is located in the center between the two pairs of vertical detection support lug positioning blocks. The vertical detection arc back auxiliary positioning block is located below the casting vertical placement platform block. The two pairs of parallel detection support lug positioning blocks are located on both sides below the vertical detection arc back auxiliary positioning block. The two parallel detection riser diameter positioning blocks are located below the two pairs of parallel detection support lug positioning blocks. The two casting parallel placement platform blocks are located between the two parallel detection riser diameter positioning blocks and the two pairs of parallel detection support lug positioning blocks. The two casting vertical placement blocks are located below the two parallel detection riser diameter positioning blocks. The casting parallel placement blocks are located at the lower part of the upper surface of the inspection platform.

[0007] In a preferred embodiment of this solution, the angle adjuster includes a left adjustment bracket and a right adjustment bracket, which are fixedly connected by a balance bar.

[0008] Furthermore, the left and right adjustment brackets have the same structure, both including: a telescopic frame, a suction cup fixedly installed at the bottom of the telescopic frame, and a universal joint connected to the top. The telescopic frame is fixedly connected to the inspection platform through the universal joint.

[0009] Furthermore, the telescopic frame includes an outer sleeve and an inner rod inserted into the outer sleeve at one end. The outer sleeve has a screw hole, and a fixing bolt is installed in the screw hole to fix the inner rod. The inner rods of the left adjustment bracket and the right adjustment bracket are fixedly connected by a balance bar.

[0010] In a preferred embodiment of this solution, a fixture hook is fixedly installed on the top of the fixture platform.

[0011] Furthermore, positioning ramps are provided at the top of both the vertical detection lug positioning block and the parallel detection lug positioning block.

[0012] Implementing this utility model has the following beneficial effects:

[0013] This caliper edge deformation inspection tool meets the actual caliper inspection needs. Compared with general inspection tools, it adds the inspection of deformation in the parallel and vertical directions as well as riser neck inspection, effectively eliminating the risk of breakage caused by deformation and the problem of assembly interference caused by excessive riser diameter.

[0014] The inspection caliper cutting deformation gauge is designed to follow the contour of the casting. The deformation detection gap is 0.25mm on one side and the riser neck detection gap is 0.9mm on one side. The caliper can confirm the qualification by passing through the gauge in the parallel and perpendicular directions, which reduces the risk of external quality control and reduces quality costs.

[0015] This inspection fixture is equipped with an angle adjuster, which allows the platform angle to be adjusted arbitrarily during inspection, making it suitable for use by various types of workers and providing high comfort. Attached Figure Description
