Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of shaft diameter detection devices, specifically relating to a shaft diameter detection device for bearing processing. Background Technology
[0002] A shaft diameter measuring device is a precision instrument specifically designed for measuring the diameter of cylindrical shaft parts. It is widely used in numerous fields, including machinery manufacturing, automotive, aerospace, and bearing production. It can quickly and accurately obtain the diameter data of shaft parts, ensuring that the parts' dimensions meet design standards. It is one of the key pieces of equipment for guaranteeing product quality and assembly accuracy.
[0003] In the field of bearing manufacturing, shaft diameter inspection is equally essential. Existing shaft diameter inspection devices are mainly divided into contact inspection devices, laser scanning inspection devices, and image-based inspection devices. The working principle of a laser scanning inspection device is as follows: a laser beam emitted from a laser emitter is formed into parallel light by an optical system and illuminates the shaft being measured. Part of the light is blocked by the shaft, while the transmitted light is received by a receiver. Based on the width of the blocked light on the receiver, combined with the parameters of the optical system, the shaft diameter can be calculated.
[0004] However, existing laser scanning inspection devices have significant problems. While bearings can be placed on a support platform for inspection, the lack of a fixing device means that when the equipment is affected by external environmental factors, such as vibration, the bearing's position will deviate, thus affecting the accuracy of the measurement data from the laser scanning inspection device. Utility Model Content
[0005] The purpose of this utility model is to provide a shaft diameter detection device for bearing processing, which aims to solve the problem that in the existing technology, although the bearing can be placed on a support platform for detection, the lack of a fixing device causes the bearing position to deviate when the equipment is affected by the external environment, such as vibration, thus affecting the accuracy of the measurement data of the laser scanning detection device.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a shaft diameter detection device for bearing processing, comprising a support, two symmetrical housings mounted on the top of the support, a laser shaft diameter measuring mechanism installed inside the housings, a control panel mounted on the outer wall of one of the housings, a support platform mounted on the top of the support, recesses mounted on the corresponding side walls of the two housings, fastening bolts threaded through the surface of the recesses, a support plate inserted into the recess of the recesses, a threaded rod and a guide rod threaded through the surface of the support plate, a first clamping block rotatably connected to the bottom end of the threaded rod, a second clamping block connected to the bottom end of the guide rod, and connecting blocks connected to the corresponding side walls of the first and second clamping blocks.
[0007] In a preferred embodiment of the bearing machining shaft diameter detection device of this utility model, the support plate can be detachably and fixedly connected to the concave block by fastening bolts.
[0008] In a preferred embodiment of the bearing machining shaft diameter detection device of this utility model, the thickness of the support plate and the recess of the concave block are the same.
[0009] In a preferred embodiment of the bearing machining shaft diameter detection device of this utility model, the threaded rod and the guide rod symmetrically penetrate the surface of the support plate, and the threaded rod and the support plate are threadedly connected.
[0010] As a preferred embodiment of the bearing machining shaft diameter detection device of this utility model, the first clamping block and the second clamping block are the same size, and the bottom ends of the first clamping block and the second clamping block are provided with arc-shaped grooves that are adapted to the top of the support platform.
[0011] In a preferred embodiment of the bearing machining shaft diameter detection device of this utility model, the first clamping block can be connected to the second clamping block via a connecting block.
[0012] In a preferred embodiment of the bearing machining shaft diameter detection device of this utility model, the first clamping block and the second clamping block can be connected to the support plate in a lifting manner through a threaded rod and a guide rod.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] Through the cooperation of the support plate, threaded rod, guide rod, first clamping block, second clamping block, and connecting block, when the bearing is placed on the support platform for shaft diameter measurement, the operator only needs to rotate the threaded rod. The threaded rod will descend along the threaded hole on the surface of the support plate, thereby pushing the first clamping block down. Since the first clamping block is connected to the second clamping block through the connecting block, the second clamping block will also descend, simultaneously driving the guide rod down. Finally, the descending first and second clamping blocks gradually approach the bearing on the support platform and work together with the support platform to firmly fix the bearing. This fixing method will not affect the normal operation of the laser shaft diameter measuring mechanism, ensuring the smooth progress of shaft diameter measurement. At the same time, it can effectively reduce external environmental interference and avoid bearing position displacement caused by vibration and other factors, thereby greatly improving the accuracy and stability of shaft diameter measurement data.
[0015] By using the fit between the recess and the fastening bolt, the operator can easily disconnect the support plate from the recess by simply tightening the fastening bolt. Then, the support plate can be smoothly pulled out from the recess of the recess, which greatly facilitates the placement of the bearing on the support platform and effectively avoids deviation in the bearing placement position due to the obstruction of the support plate, ensuring that the bearing can be placed in the predetermined position.

[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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Please see Figures 1-4 This utility model provides the following technical solution: a shaft diameter detection device for bearing processing, including a support 1, two symmetrical boxes 2 installed at the top of the support 1, a laser shaft diameter measuring mechanism 3 installed inside the box 2, a control panel 4 installed on the outer wall of one of the boxes 2, a support platform 5 installed at the top of the support 1, recesses 6 installed on the corresponding side walls of the two boxes 2, fastening bolts 7 threaded through the surface of the recesses 6, a support plate 8 inserted into the recess of the recesses 6, a threaded rod 9 and a guide rod 10 threaded through the surface of the support plate 8, a first clamping block 11 rotatably connected to the bottom end of the threaded rod 9, a second clamping block 12 connected to the bottom end of the guide rod 10, and connecting blocks 13 connected to the corresponding side walls of the first clamping block 11 and the second clamping block 12.
[0024] In practical use, the shaft diameter detection device mainly consists of a support 1, a housing 2, a laser shaft diameter measuring mechanism 3, a control panel 4, and a support platform 5. The laser shaft diameter measuring mechanism 3 is its core measuring component. It uses a laser beam emitted by a laser emitter, which is processed by an optical system to form parallel light before being projected onto the bearing being measured. At this time, some of the light is blocked by the bearing, while the transmitted light is received by a receiver. By measuring the width of the blocked light on the receiver and combining this with relevant parameters of the optical system, the shaft diameter of the bearing can be accurately calculated. In short, the laser shaft diameter measuring mechanism 3 mainly consists of key components such as a laser emitter and a receiver. Furthermore, the control panel 4 plays a crucial control and feedback role in the entire device. Operators can use it to start the laser shaft diameter measuring mechanism 3 and simultaneously obtain the measurement data fed back by the mechanism.
[0025] Preferably, the support plate 8 can be detachably and fixedly connected to the recessed block 6 by fastening bolts 7. The thickness of the support plate 8 and the recessed block 6 are the same. The threaded rod 9 and the guide rod 10 symmetrically penetrate the surface of the support plate 8, and the threaded rod 9 and the support plate 8 are connected by threads.
[0026] In practical use, the operator only needs to tighten the fastening bolt 7 to quickly disconnect the connection between the support plate 8 and the recess 6. Then, the support plate 8 can be smoothly pulled out from the recess of the recess 6. This operation greatly facilitates the placement of the bearing on the support platform 5 and effectively avoids the problem of bearing placement deviation caused by the obstruction of the support plate 8, thereby ensuring that the bearing can be correctly placed in the preset position.
[0027] Preferably, the first clamping block 11 and the second clamping block 12 are the same size, and both the first clamping block 11 and the second clamping block 12 have an arc-shaped groove at their bottom ends that matches the top of the support platform 5. The first clamping block 11 can be connected to the second clamping block 12 via a connecting block 13. The first clamping block 11 and the second clamping block 12 can be connected to the support plate 8 in a lifting manner via a threaded rod 9 and a guide rod 10.
[0028] In practical use, when the bearing is placed on the support platform 5 for shaft diameter testing, the operator only needs to rotate the threaded rod 9, and the threaded rod 9 will slowly descend along the threaded hole on the surface of the support plate 8. As the threaded rod 9 descends, it will push the first clamping block 11 to descend together. Since the first clamping block 11 is tightly connected to the second clamping block 12 through the connecting block 13, the second clamping block 12 will also descend under the drive of the first clamping block 11, and simultaneously drive the guide rod 10 to descend.
[0029] Ultimately, the descending first clamping block 11 and the second clamping block 12 will gradually approach the bearing on the support platform 5, cooperate with the support platform 5, and firmly fix the bearing.
[0030] This fixing method will not interfere with the normal operation of the laser shaft diameter measuring mechanism 3, ensuring that the shaft diameter detection work can be carried out in an orderly and smooth manner. At the same time, it can effectively reduce the interference from the external environment and avoid the bearing position from shifting due to factors such as vibration, thereby greatly improving the accuracy and stability of the shaft diameter detection data.
[0031] It is worth noting that the guide rod 10 is used to prevent the first clamping block 11 from rotating together with the threaded rod 9, thereby affecting the use of the first clamping block 11.
[0032] Working principle: First, the operator only needs to tighten the fastening bolt 7 to quickly disconnect the connection between the support plate 8 and the recess 6. Then, the support plate 8 is smoothly pulled out from the recess of the recess 6 to make room for the subsequent placement of the bearing.
[0033] Then, the bearing is accurately placed on the support platform 5. Since the support plate 8 has been removed, the bearing placement position is effectively avoided due to the obstruction of the support plate 8, ensuring that the bearing can be placed in the preset position.
[0034] Then, the support plate 8 is pushed back into the recess 6 and firmly fixed with the fastening bolt 7. Next, the operator rotates the threaded rod 9, which slowly descends along the threaded hole on the surface of the support plate 8. As the threaded rod 9 descends, it pushes the first clamping block 11 down as well. Because the first clamping block 11 is tightly connected to the second clamping block 12 through the connecting block 13, the second clamping block 12 will descend synchronously under the action of the first clamping block 11, simultaneously driving the guide rod 10 down.
[0035] Ultimately, the descending first clamping block 11 and the second clamping block 12 will gradually approach the bearing on the support platform 5, cooperating with the support platform 5 to firmly fix the bearing in place and prevent the bearing from shifting during the testing process.
[0036] Finally, the operator uses control panel 4 to start the laser shaft diameter measuring mechanism 3. The laser shaft diameter measuring mechanism 3 then begins working to measure the shaft diameter of the bearing. After the measurement is completed, the relevant data will be fed back to control panel 4 for the operator to view and analyze.
[0037] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
