Description

Technical Field

[0001] This utility model relates to the field of measuring mechanism technology, specifically a six-point measuring mechanism for bearing wall thickness. Background Technology

[0002] The six-point measuring mechanism for bearing wall thickness is a special testing device for accurately measuring the uniformity of bearing wall thickness. It determines the wall thickness by measuring the distance difference between the inner and outer surfaces of the bearing. The six measuring points are measured simultaneously or sequentially to obtain the wall thickness distribution data. Therefore, it can be seen that the existing measuring mechanism basically meets people's needs, but the following problems still exist.

[0003] When an operator is measuring the wall thickness of a bearing bush, the operator places the bearing bush on a support frame and then places the detection probe around the bearing bush to collect information and measure its thickness. However, because the operator may need to adjust the position of the detection probe each time the bearing bush is measured to vary its curvature and size, the inconvenience of adjusting the probe's position may limit the applicability of the testing device. Therefore, a six-point measuring mechanism for bearing bush wall thickness is proposed. Utility Model Content

[0004] The purpose of this invention is to address the current problem of the inability to adjust the angle.

[0005] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0006] A six-point measuring mechanism for bearing wall thickness is provided to improve the above-mentioned problems.

[0007] The application is as follows:

[0008] A six-point measuring mechanism for bearing wall thickness includes a base, a support frame, a probe, a horizontal actuator, and a mounting frame. The horizontal actuator is slidably connected to the end of the base, and the mounting frame is mounted on the end of the horizontal actuator. Probes are arranged around the mounting frame, and the ends of the probes are fixed to the support frame on the base. Several sets of mounting sleeves and collars are sequentially fitted onto the ends of the mounting frame, and the collars are elastically connected to the base. Several sets of abutments are fixed to the surfaces of the mounting frame and the mounting sleeves, and the surfaces of the abutments are fitted with abutment grooves opened on the other side of the mounting sleeve. A fixing frame is fixed to any side of the outer wall of the mounting sleeve, and the surface of the fixing frame is fitted with a mounting ring, and the mounting ring is threadedly connected to the fixing frame. The outer wall of the mounting ring is fixed with a probe.

[0009] As a preferred technical solution of this application, a traction sleeve is fixed to the outer wall of the collar, and a positioning pin passes through the middle of the traction sleeve. The end of the positioning pin is fitted with a positioning groove opened on the mounting bracket, and a traction rod fixed to the inner wall of the traction sleeve passes through the inside of the positioning pin.

[0010] As a preferred technical solution of this application, the positioning pin has a waist-shaped hole in the middle, and the traction rod is configured as a cylinder that matches the inner wall of the waist-shaped hole in the middle of the positioning pin.

[0011] As a preferred technical solution of this application, all the positioning pins are cylindrical, and the ends of the positioning pins are all chamfered.

[0012] As a preferred technical solution of this application, a traction block is fixed on the inner wall of the mounting sleeve near the collar side, and a traction groove is provided on the surface of the traction block on the outer wall of the mounting frame.

[0013] As a preferred technical solution of this application, both the mounting ring and the fixing frame are penetrated by bolts in the middle, and the ends of the bolts are threaded with nuts.

[0014] As a preferred technical solution of this application, a slider is fixed to the inner wall of the collar, and a groove is provided on the surface of the slider in the middle of the mounting frame. A sliding rod is fixed to the inner wall of the groove, passing through the slider, and a spring is wound on the surface of the sliding rod, which abuts against the surface of the slider and the inner wall of the groove respectively.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] In the scheme of this application:

[0017] The system utilizes a set of abutment grooves, sliders, mounting sleeves, and collars. The operator pulls the collar to slide it across the mounting frame surface, preventing the mounting frame from abutting against the various sets of mounting sleeves. The operator then pushes the mounting sleeves, causing them to rotate on the mounting frame surface. This rotation, via the fixing frame, drives the probe head to rotate, facilitating position adjustment of the probe head. Subsequently, the collar is pushed again, and the mounting sleeves engage with the abutment block and abutment groove, securing the collar to the mounting sleeves. This allows the operator to fix the position of the fixing frame and adjust the position of the various sets of probe heads according to the shape of the bearing bush, thus expanding the operator's usability.

[0018] With the help of a positioning pin, a traction sleeve, and a positioning groove, the operator pulls the positioning pin, which slides within the traction sleeve and moves out of the positioning groove. This removes the positioning pin and groove from fixing the collar, allowing the collar to slide on the mounting surface. The operator then inserts the positioning pin back into the positioning groove to fix the collar in place. When adjusting the mounting frame, the operator no longer needs to continuously pull the collar, improving ease of use. Attached Figure Description

[0033] Example 1: Please refer to the appendix of the instruction manual. Figures 1-7As shown, a six-point measuring mechanism for bearing wall thickness includes a base 1, a support frame 2, a probe 3, a horizontal actuator 4, and a mounting frame 5. The horizontal actuator 4 is slidably connected to the end of the base 1, and the mounting frame 5 is mounted on the end of the horizontal actuator 4. Probes 3 are arranged around the mounting frame 5, and the end of each probe 3 is fixed to the support frame 2 on the base 1. Several sets of mounting sleeves 10 and collars 9 are sequentially fitted onto the end of the mounting frame 5, and the collars 9 are elastically connected to the base 1. A slider 13 is welded to the inner wall of the collar 9, and a groove 8 is formed in the middle of the mounting frame 5 on the surface of the slider 13. A sliding rod 6 is welded through the slider 13 on the inner wall of the groove 8, and springs 7 are wound around the surface of the sliding rod 6, respectively abutting against the surface of the slider 13 and the inner wall of the groove 8. The mounting frame 5... Several sets of abutments 11 are welded to the surface of the mounting sleeve 10, and the surface of each abutment 11 is fitted with an abutment groove 12 opened on the other side of the mounting sleeve 10. A fixing frame 14 is welded to any side of the outer wall of the mounting sleeve 10, and a mounting ring 21 is fitted to the surface of each fixing frame 14. The mounting ring 21 is threadedly connected to the fixing frame 14. A bolt 22 passes through the middle of both the mounting ring 21 and the fixing frame 14, and a nut 23 is threaded onto the end of each bolt 22. A probe head 3 is welded to the outer wall of the mounting ring 21. When the operator needs to adjust the position of the fixing frame 14, the operator holds the ring 9 on the surface of the collar 9 and then pulls the collar 9. The collar 9 drives the slider 13 to slide in the groove 8. When the slider 13 slides in the groove 8, The circular through-hole in the middle of the slider 13 slides on the surface of the cylindrical slide rod 6, allowing the slider 13 to slide stably within the slide groove 8. When the slider 13 moves, it compresses the spring 7 wound around the surface of the slide rod 6, causing the spring 7 to elastically deform. After the spring 7 elastically deforms, it avoids the slider 13, causing the slider 13 to drive the collar 9 to slide on the surface of the mounting bracket 5. Once the collar 9 no longer abuts against the mounting sleeve 10, the operator pulls the mounting sleeve 10, causing it to slide on the surface of the mounting bracket 5, separating several sets of mounting brackets 5 from each other. Furthermore, when the mounting sleeve 10 moves, it causes the abutment block 11 to move out of the surface of the abutment groove 12, preventing the abutment block 11 and the abutment groove 12 from interfering with each other. After engagement, the mounting sleeve 10 can drive the fixing frame 14 to rotate on the surface of the mounting frame 5. After the positions of the fixing frames 14 on both sides are adjusted, the operator pushes the mounting sleeve 10 again. The mounting sleeve 10 drives the abutment groove 12 to be fitted onto the surface of the abutment block 11, so that the abutment block 11 and the abutment groove 12 engage with each other, connecting several sets of mounting sleeves 10 together. After the operator releases their hand from the surface of the collar 9, the collar 9 no longer compresses the spring 7 through the slider 13. The spring 7 recovers its elastic deformation and pushes the slider 13 to move, causing the slider 13 to drive the collar 9 to move, causing the collar 9 to push the mounting sleeve 10 to move, so that the collar 9 abuts against several sets of mounting sleeves 10, and the several sets of mounting sleeves 10 engage with each other through the abutment groove 12 and the abutment block 11.The mounting sleeve 10 is positioned on the mounting bracket 5 to facilitate the operator's fixation of the mounting bracket 14, and the angle of the probe head 3 can be adjusted. The base 1, support bracket 2, probe head 3, horizontal actuator 4, and mounting bracket 5 are widely used in the field, and their structure and principles are well known to those skilled in the art; therefore, they will not be described in detail here.

[0034] A traction block 16 is welded to the inner wall of the mounting sleeve 10 near the collar 9, and a traction groove 15 is provided on the surface of the traction block 16 on the outer wall of the mounting frame 5. When the mounting sleeve 10 near the collar 9 moves, the mounting sleeve 10 drives the traction block 16 to slide in the traction groove 15, so that the traction block 16 and the traction groove 15 pull the position of the mounting sleeve 10, increasing the stability of the mounting sleeve 10 in sliding on the surface of the mounting frame 5, and preventing the mounting sleeve 10 from rotating on the surface of the mounting frame 5.

[0035] Example 2: Please refer to the appendix of the instruction manual. Figures 1-7 As shown, a traction sleeve 18 is welded to the outer wall of the collar 9, and a positioning pin 17 passes through the middle of the traction sleeve 18. A positioning groove 19, which is opened on the mounting frame 5, is fitted at the end of the positioning pin 17. A traction rod 20, welded to the inner wall of the traction sleeve 18, passes through the inside of the positioning pin 17. When the operator needs to pull the collar 9 to slide on the surface of the mounting frame 5, the operator first pulls the positioning pin 17, causing it to slide within the traction sleeve 18. While the positioning pin 17 is sliding within the traction sleeve 18, the oblong hole in the middle of the positioning pin 17 slides on the surface of the cylindrical traction rod 20, moving the positioning pin 17 out of the positioning groove 19. The positioning pin 17 and the positioning groove 19... After the mounting bracket 5 and collar 9 are no longer fixed, the collar 9 slides on the surface of the mounting bracket 5. After the collar 9 moves the positioning pin 17 to the front end of the other positioning groove 19 through the traction sleeve 18, the positioning pin 17 is no longer supported by the mounting bracket 5. Under the action of gravity, the positioning pin 17 inserts into the other positioning groove 19. After the positioning pin 17 and the other positioning groove 19 are no longer fixed to the collar 9 and the mounting bracket 5, it is convenient for the operator to fix the position of the collar 9. When the operator needs to adjust the fixing bracket 14, the operator no longer needs to keep pulling the collar 9, which improves the convenience of the operator.

[0036] The positioning pin 17 has a waist-shaped hole in the middle. The traction rod 20 is set as a cylinder that matches the inner wall of the waist-shaped hole in the middle of the positioning pin 17. The waist-shaped hole in the middle of the positioning pin 17 matches the cylinder of the traction rod 20. When the waist-shaped hole in the middle of the positioning pin 17 slides on the cylindrical surface of the traction rod 20, the waist-shaped hole in the middle of the positioning pin 17 avoids the traction rod 20. When the positioning pin 17 moves, the waist-shaped hole in the middle of the positioning pin 17 avoids the traction rod 20. Furthermore, the traction rod 20 passes through the waist-shaped hole in the middle of the positioning pin 17, which restricts the positioning pin 17 and prevents the positioning pin 17 from falling out of the traction sleeve 18 when it slides inside the traction sleeve 18. This makes it convenient for the operator to use.

[0037] All positioning pins 17 are cylindrical, and the ends of all positioning pins 17 are set with semi-circular chamfers. By setting the cylindrical ends of positioning pins 17 with semi-circular chamfers, the surface diameter of the end of positioning pins 17 is reduced, which makes it easier for positioning pins 17 to be inserted into positioning grooves 19, thus increasing the convenience of inserting positioning pins 17 into positioning grooves 19.

[0038] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model in any way. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall fall within the scope of the technical solution of the present utility model.
