Description

Technical Field

[0001] The present invention relates to the technical field of detection tooling, in particular to a three-coordinate detection tooling. Background Art

[0002] The brake disc, also known as the brake disc or brake disc, is an important part of the braking system of a motor vehicle. It is usually a disc-shaped metal part installed on the wheel to create friction during braking, slow down or stop the vehicle. The brake disc is inspected by three-coordinate detection. Among them, three-coordinate detection is to use a three-coordinate measuring machine to inspect and measure the form and position tolerances of the workpiece to determine whether the error of the workpiece is within the tolerance range.

[0003] However, in order to facilitate measurement, a special fixture is used during the three-coordinate inspection of the brake disc to fix the workpiece and locate the reference. During actual measurement, the staff uses the fixture to clamp and measure the brake disc, but the movable clamp in the existing fixture is in a suspended state, and the clamping is completed through mechanical cooperation with the lead screw and the support rod. The rotation of the lead screw drives the horizontal movement of the movable plate on its surface. At this time, the horizontal movement of the movable clamp on the support rod makes the movable clamp always in a state of horizontal movement. As the number of times the fixture is used increases, the movement of the movable clamp on the support plate will also increase accordingly. At this time, it will cause wear of the support rod, and the worn support rod will produce a gap with the movable clamp, and the movable clamp will shake when clamping. In addition, since the lead screw is thin, the staff needs to turn the nut multiple times to ensure the clamp workpiece. If the staff does not confirm the clamping condition after clamping, it will cause the brake disc to shake during measurement, thereby affecting the accuracy of the brake disc detection data. Summary of the invention

[0004] The present invention provides a three-coordinate detection tooling, which solves the problems raised by the above-mentioned background technology.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: a three-coordinate detection tooling, including a base, a fixed plate is fixedly installed on the upper end of the base, a positioning plate is fixedly connected to the right side of the fixed plate, and the lower end of the positioning plate is fixedly connected to the upper end surface of the base, a screw seat is fixedly installed on the right side of the upper end surface of the base, the screw seat is connected to the movable plate through a screw, a connecting seat located on the front and rear sides of the screw is fixedly installed on the right side of the movable plate, and a movable component is fixedly connected to the lower end of the connecting seat.

[0006] Optionally, the right end of the screw is fixedly sleeved with a sleeve rod located on the right side of the screw seat, and a rotating knob is fixedly installed on the end of the sleeve rod away from the screw.

[0007] Optionally, the movable component includes a slide seat, and the middle part of the lower end of the slide seat is slidably connected to a slide rail located at the upper end of the base.

[0008] Optionally, the upper end of the slide seat is fixedly connected to the lower end of the connecting seat, and cleaning components located outside the slide rail are fixedly mounted on both left and right sides of the slide seat.

[0009] Optionally, grooves are provided on both the front and rear sides of the upper end surface of the base, and the upper end surface of the groove is fixedly connected to the lower end of the slide rail. The upper end surface of the base is fixedly connected to the lower ends of the fixing plate, the positioning plate, and the screw seat from left to right.

[0010] Optionally, the connecting seat includes a vertical plate, a support plate is fixedly installed on the right side of the vertical plate, a left side plate located above the slide seat is fixedly installed on the left side of the lower end of the vertical plate, and a right side plate is fixedly connected to the right side of the lower end of the left side plate.

[0011] Optionally, the cleaning assembly includes a brush plate, the inner side of which is evenly distributed with bristles located outside the slide rail, the inner wall of the brush plate is threadedly sleeved with a fastening bolt, and the outer wall of the inner end of the fastening bolt is threadedly sleeved with the inner wall of the slide seat.

[0013] The present invention has the following beneficial effects: 1. The three-coordinate inspection fixture effectively solves the problem of support rod wear caused by long-term clamping work through the coordination between the movable plate, slide seat, slide rail, screw and fixed plate. The slide rail slides on the slide seat instead of the movable splint moving on the support rod, avoiding the wear of the support rod and the gap between the movable splint. The sliding of the slide seat on the slide rail not only strengthens the stability of the movable plate during movement, but also improves the stability of the movable plate and the fixed plate after clamping the brake disc, thereby improving the accuracy of the brake disc detection data.

[0014] 2. The three-coordinate inspection tooling realizes the impurity removal function on the slide surface through the coordination between the bristles, fastening bolts, slide and slide, and utilizes the setting of the bristles, effectively solving the problem of wear of the slide caused by impurities on the slide. The movement of the slide drives the bristles to move on the surface of the slide rail, thereby preventing the wear caused by contact with impurities when the slide slides on the slide rail, reducing the damage to the slide rail and the slide seat, and extending the service life of the slide rail and the slide seat.

[0015] 3. The three-coordinate inspection tooling realizes the connection between the bristles and the slide seat through the coordination among the bristles, the fastening bolts and the slide seat and utilizes the setting of the fastening bolts, thereby effectively solving the problem of the bristles being worn after long-term use. By changing the connection method between the fastening bolts and the slide seat or the brush plate, the steps of disassembly and assembly of the bristles are simplified, the worn bristles can be replaced in time, and the cleaning effect of the bristles on the slide rail is improved.

Due to the fixed sleeve connection between the sleeve rod 9 and the screw 5, the rotation of the rotating knob 10 drives the rotation of the screw 5. Due to the threaded sleeve connection between the screw 5 and the screw seat 4, the screw 5 can realize its horizontal movement while rotating in a circular direction. The movement of the screw 5 drives the movable plate 6 to move in the same direction. Then, the movable plate 6 drives the slide 801 to slide on the slide rail 802 through the connection of the connecting seat 7.
