Description

Technical Field

[0001] The utility model relates to the technical field of detection, in particular to a caliper bearing housing diameter detection device. Background Art

[0002] Caliper bearings are mainly used in automotive brakes. Their outer shells are semi-circular. After the outer shells are press-formed, it is necessary to detect the outer diameter.

[0003] In the existing detection methods, manual use of calipers is mostly adopted to measure the lengths on both sides in the width direction of the outer shell respectively, and observe whether the two measurement values are within the technical requirements to judge whether the outer shell diameter is qualified. This detection method not only has low efficiency, but also has low accuracy as the detection results are observed only by the eyes of the detection personnel, and the working intensity is also relatively large. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is: in order to overcome the deficiencies in the prior art, the utility model provides a caliper bearing housing diameter detection device which is convenient to operate and can improve the detection accuracy.

[0005] The technical solution adopted by the utility model to solve its technical problem is: a caliper bearing housing diameter detection device, which has a base. A bracket is installed on the base, and a detection table is fixed on the upper end surface of the bracket. Two support plates are arranged on the detection table at a certain distance left and right. The semi-circular housing of the bearing to be detected is clamped between the support plates. A displacement sensor with a touch rod extending out of the upper end surface of the detection table is arranged at a certain distance front and back on the bottom surface of the detection table. During detection, the top of the touch rod of the displacement sensor contacts the lowest points on the front and back sides of the outer wall surface of the semi-circular housing. A pressure rod is arranged directly above the semi-circular housing and presses against the center of the inner wall of the semi-circular housing during detection.

[0006] Specifically, a cylinder is installed on the rear side surface of the bracket. The top end of the piston rod of the cylinder is fixedly connected with a connecting block. The pressure rod is movably arranged through the front end of the connecting block, and a buffer spring is sleeved on the pressure rod.

[0007] Furthermore, limit pins are arranged at a certain distance front and back on the upper end surface of the support plate. The left and right ends of the semi-circular housing are respectively clamped between the corresponding limit pins.

[0008] The beneficial effect of the utility model is: the utility model uses two displacement sensors to detect the displacement amounts generated after the two sides of the semi-circular housing of the caliper bearing are pressed, so as to quickly determine whether the diameter length of the semi-circular housing is within the range specified by the technical requirements. The detection process is fast and convenient, and the detection accuracy is relatively high. Description of the Drawings

[0013] Now, the present utility model will be further described in detail with reference to the accompanying drawings. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present utility model in a schematic manner, so they only show the components related to the present utility model.

[0014] As Figure 1 , Figure 2 shown, a caliper bearing housing diameter detection device includes a base 1 installed on the ground. A bracket 2 is installed on the base 1, and a detection table 3 is fixed between the upper end faces of the bracket 2. Two support plates 4 are provided at left and right intervals on the upper end face of the detection table 3. Limit pins 11 are provided at front and rear intervals on the upper end face of each support plate 4. The left and right ends of the semi-circular housing 5 of the caliper bearing to be detected are respectively clamped between the corresponding limit pins 11.

[0015] Two displacement sensors 6 are installed at front and rear intervals on the bottom surface of the detection table 3. The touch rods of the two displacement sensors 6 extend out of the upper end face of the detection table 3, and a touch plate is provided at the top of the touch rod.

[0016] A cylinder 8 is installed on the rear side surface of the bracket 2. The top end of the piston rod of the cylinder 8 is fixedly connected with a connecting block 9. The front end part of the connecting block 9 is located directly above the semi-circular housing 5. A through hole is opened in the front end part of the connecting block 9, and a pressing rod 7 is movably inserted through the through hole. The pressing rod 7 includes a rod body, a stop block and a cone which are of an integral structure. The stop block is located at the top of the rod body, and the cone is located at the bottom of the rod body. A buffer spring 10 is sleeved on the rod body between the stop block and the cone.

[0017] The detection principle of this device is: Make a standard part for the upper limit and the lower limit of the diameter size tolerance of the semi-circular housing 5 of the detection product respectively, place them on the displacement sensor 6, and set the corresponding tolerance upper limit and tolerance lower limit on the display control panel connected to the displacement sensor 6. When detecting the product, if the displayed tolerance size is between the upper limit and the lower limit, it is a qualified product.

[0018] During detection, place the semi-circular housing 5 between the limit pins 11 on the upper end faces of the two support plates 4. After positioning the semi-circular housing 5, start the cylinder 8 to drive the pressure rod 7 to descend. When the cone at the bottom of the pressure rod 7 contacts the inner wall surface of the semi-circular housing 5, the cylinder 8 stops. The acting force generated by the compression of the buffer spring 10 presses the tip of the cone of the pressure rod 7 against the center of the inner wall surface of the semi-circular housing 5. The contact plate at the top of the contact rod of the displacement sensor 6 contacts and is pressed by the lowest points on the front and rear sides of the outer wall surface of the semi-circular housing 6. The displacement amount generated by the displacement sensor 6 is transmitted to the display. The detection personnel observe whether the displacement values measured by the two displacement sensors 6 displayed on the control panel are within the set upper tolerance limit and lower tolerance limit, so as to determine whether the diameter length of the semi-circular housing 6 is within the range specified by the technical requirements.

[0019] Inspired by the ideal embodiments of the present utility model described above, through the above description, relevant staff can completely make various changes and modifications without departing from the technical idea of this utility model. The technical scope of this utility model is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
