Technical Field
[0001] This utility model relates to the field of parts height detection technology, specifically a tooling for detecting the height of automotive parts. Background Technology
[0002] The function of automotive parts is to form the body structure and components, such as supporting and installing the car engine and its various parts, so that the car can operate normally and ensure normal driving. After the bearings and pistons are processed, they need to be height checked by a height detection device.
[0003] In the prior art, height detection devices mainly include a base, a scale plate, and a clamping plate. After the part is placed on the base, the clamping plate is moved to contact its top. Then, the position of the clamping plate on the scale plate is read, and the height of the part is detected by comparing it with a standard value. However, during the process of moving the clamping plate back and forth to place and replace the part, the friction between the clamping plate and the scale plate may cause wear on the scale plate, which in turn affects the accuracy of the device in detecting the height of the part.
[0004] Therefore, a height detection fixture for automotive parts is proposed to address the above problems. Utility Model Content
[0005] To overcome the shortcomings of existing technologies and solve the problem that friction between the clamping plate and the scale plate during the placement and replacement of parts by the reciprocating moving clamping plate may cause wear on the scale plate, thereby affecting the accuracy of the device in detecting the height of parts, a height detection fixture for automotive parts is proposed.
[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A height detection fixture for automotive parts, comprising a base, a part to be inspected placed at the top center of the base, a scale side plate fixedly connected to the center of one outer wall of the base, an adjustment component provided on the outside of the scale side plate, a straight groove opening on the side wall of the scale side plate, a lifting plate above the base, a connecting bracket fixedly connected to the center of one outer wall of the lifting plate, the connecting bracket slidably communicating with the straight groove opening, a through hole at the top center of the lifting plate, a guide rod slidably communicating within the through hole, a contact circular plate installed at one end of the guide rod, the bottom of the contact circular plate contacting the top of the part to be inspected, and a displacement scale body installed on the top of the lifting plate, the sensor of the displacement scale body corresponding to the outer wall of the guide rod.
[0007] Preferably, the other end of the guide rod is fixedly connected to a limiting circular plate, and a spring is slidably fitted on the outside of the guide rod.
[0008] Preferably, both ends of the spring are fixedly connected to a ring plate, and both ring plates are slidably fitted onto the outside of the guide rod. One ring plate is in contact with the top of the lifting plate, and the other ring plate is in contact with the bottom of the limiting ring plate.
[0009] Preferably, the adjusting component includes a threaded sleeve, the outer wall of which is fixedly connected to one end of the connecting bracket.
[0010] Preferably, the threaded sleeve is internally threaded with a lead screw, one end of which is fixedly connected to a mounting bracket via a bearing, and the mounting bracket is fixedly connected to the lower side wall of the scale side plate.
[0011] Preferably, an annular groove is formed on the outer wall of the lead screw near the other end edge, and a limiting sleeve is installed inside the annular groove. One side of the limiting sleeve is fixedly connected to the upper side wall of the scale side plate.
[0012] Preferably, a rotating handle is fixedly connected to the other end of the lead screw, and a pressing handle is fixedly connected to the outside of the limiting circular plate.
[0013] The beneficial effects of this utility model are:
[0014] In this invention, the base is used to place the part to be inspected, and the lifting plate is connected to the straight groove opening on the part to be inspected via a connecting bracket. The distance between the base and the lifting plate can be read by the scale on the scale side plate. The displacement scale instrument body can record the displacement after the contact circular plate on the guide rod contacts the top of the part to be inspected. The device can read the relative height of the part to be inspected by comparing the displacement with the scale at the position of the lifting plate. In the above method, it is not necessary to move the lifting plate to replace the part to be inspected, thereby reducing the relative friction between the scale side plate and the lifting plate, reducing the impact of scale wear on the scale side plate on the detection accuracy of the device, and increasing the practicality of the device.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0023] Specific implementation examples are given below.
[0024] Please see Figure 1 - Figure 4This utility model provides a height detection fixture for automotive parts, including a base 1. A part 2 to be inspected is placed at the top center of the base 1. A scale side plate 3 is fixedly connected to the center of one outer wall of the base 1. An adjustment component 4 is provided on the outside of the scale side plate 3. A straight groove opening 31 is formed on the side wall of the scale side plate 3. A lifting plate 5 is provided above the base 1. A connecting bracket 51 is fixedly connected to the center of one outer wall of the lifting plate 5, and the connecting bracket 51 slides through the straight groove opening 31. A through hole 52 is formed at the top center of the lifting plate 5. A guide rod 6 slides through the through hole 52. A contact circular plate 61 is installed at one end of the guide rod 6. The bottom of the contact circular plate 61 contacts the top of the part 2 to be inspected. A displacement scale body 7 is installed on the top of the lifting plate 5. The sensor of the displacement scale body 7 corresponds to the outer wall of the guide rod 6. The part 2 to be inspected is placed on the base 1, and the lifting plate 5 is lifted into place. The lowering plate 5 is connected to the straight groove opening 31 on the part to be inspected 2 via the connecting bracket 51. The relative height between the lowering plate 5 and the scale side plate 3 is adjusted by the adjusting component 4. Before the height of the part to be inspected 2 is measured, the contact round plate 61 at one end of the guide rod 6 does not contact the top surface of the part to be inspected 2. The scale value of the lowering plate 5 on the scale side plate 3 is recorded at this time. Then the guide rod 6 is pressed down to make the contact round plate 61 contact the top surface of the part to be inspected 2. At this time, the displacement scale instrument body 7 can record the displacement of the guide rod 6. The height data of the part to be inspected 2 is obtained by subtracting the reading of the lowering plate 5 from the displacement. During the replacement of the part to be inspected 2, the process of the guide rod 6 moving up and down through the through hole 52 will not cause wear to the scale of the scale side plate 3, so as to reduce the relative friction between the connecting bracket 51 and the scale side plate 3 and reduce the movement loss between the scale side plate 3 and the lowering plate 5.
[0025] like Figure 1 , Figure 3 and Figure 4 As shown, the other end of the guide rod 6 is fixedly connected to a limiting circular plate 62. A spring 8 is slidably fitted on the outside of the guide rod 6. Both ends of the spring 8 are fixedly connected to circular ring plates 81. Both circular ring plates 81 are slidably fitted on the outside of the guide rod 6. One circular ring plate 81 contacts the top of the lifting plate 5, and the other circular ring plate 81 contacts the bottom of the limiting circular plate 62. The outer wall of the guide rod 6 cooperates with the contact circular plate 61 and the scale side plate 3 to install the spring 8 and the circular ring plate 81, providing elastic force for the overall upward movement of the guide rod 6. The two ends of the spring 8 contact the limiting circular plate 62 and the lifting plate 5 through the circular ring plate 81, so that the spring 8 and the circular ring plate 81 can be replaced as a whole after the contact circular plate 61 is removed from one end of the guide rod 6.
[0026] like Figure 1 , Figure 2 and Figure 4As shown, the adjusting assembly 4 includes a threaded sleeve 41. The outer wall of the threaded sleeve 41 is fixedly connected to one end of the connecting bracket 51. A lead screw 42 is installed on the inner thread of the threaded sleeve 41. One end of the lead screw 42 is fixedly connected to a mounting bracket 43 via a bearing. The mounting bracket 43 is fixedly connected to the lower side wall of the scale side plate 3. An annular groove 421 is formed on the outer wall of the lead screw 42 near the other end edge. A limiting sleeve 44 is installed inside the annular groove 421. One side of the limiting sleeve 44 is fixedly connected to the upper side wall of the scale side plate 3. A rotating handle 45 is fixedly connected to the other end of the lead screw 42. A pressing handle 63 is fixedly connected to the outside of the circular plate 62. A threaded sleeve 41 is installed at one end of the connecting bracket 51 and a lead screw 42 is installed. The lead screw 42 is installed on the limiting sleeve 44 through the annular groove 421. The lead screw 42 is installed with the cooperation of the mounting bracket 43 and the limiting sleeve 44. When adjusting the relative height of the lifting plate 5, the rotating handle 45 is rotated. The lead screw 42 only rotates when the rotating handle 45 rotates actively. When the pressing handle 63 is pressed down so that the contacting circular plate 61 contacts the top of the part to be inspected 2, the lead screw 42 will not rotate.
[0027] Working principle: The part to be inspected 2 is placed on the base 1. The lifting plate 5 is connected to the straight groove opening 31 on the part to be inspected 2 via the connecting bracket 51. The relative height between the lifting plate 5 and the scale side plate 3 is adjusted by the adjusting component 4. Before the height of the part to be inspected 2 is measured, the contact circular plate 61 at one end of the guide rod 6 is not in contact with the top surface of the part to be inspected 2. The scale value of the lifting plate 5 on the scale side plate 3 is recorded at this time. Then, the guide rod 6 is pressed down to make the contact circular plate 61 contact the top surface of the part to be inspected 2. At this time, the displacement scale instrument body 7 can record the displacement of the guide rod 6. The height data of the part to be inspected 2 is obtained by subtracting the reading of the lifting plate 5 from the displacement. The outer wall of the guide rod 6 cooperates with the contact circular plate 61 and the scale side plate 3 to control the spring 8 and the ring plate 81. The spring 8 is installed to provide elastic force for the overall upward movement of the guide rod 6. The two ends of the spring 8 are in contact with the limiting circular plate 62 and the lifting plate 5 through the circular plate 81, so that the spring 8 and the circular plate 81 can be replaced as a whole after the contact circular plate 61 is removed from one end of the guide rod 6. The threaded sleeve 41 is installed at one end of the connecting bracket 51 and the lead screw 42 is installed. The lead screw 42 is installed with the limiting sleeve 44 through the circular groove 421. The lead screw 42 is installed with the cooperation of the mounting bracket 43 and the limiting sleeve 44. When adjusting the relative height of the lifting plate 5, the rotating handle 45 is rotated. The lead screw 42 only rotates when the rotating handle 45 is actively rotated. When the pressing handle 63 is pressed down so that the contact circular plate 61 contacts the top of the part to be inspected 2, the lead screw 42 will not rotate.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
