Description

Technical Field

[0001] The utility model relates to the field of chassis part detection, and particularly relates to a positioning tooling for automobile chassis part detection. Background Technique

[0002] A positioning tooling for automobile chassis part detection is a tooling used to fix the parts of an automobile chassis in the field of automobile chassis processing to facilitate detection. It mainly serves as an assisting mechanism in the automobile detection process. The Chinese patent with the publication number CN218566906U proposes a positioning tooling for automobile chassis part detection. This positioning tooling for automobile chassis part detection can be adjusted adaptively according to the situation of the top of the automobile chassis part by adjusting the position of the pressure rod on the lifting plate, so that the automobile chassis part can be fixed under the extrusion of the pressure rod, realizing the positioning and fixing of the automobile chassis part in the vertical direction, and having strong fastening ability.

[0003] In the above device, the pressure rod positions the automobile chassis part through the vertical descent of the lifting plate. Although this positioning method can achieve the positioning of the chassis part to a certain extent, there are some obvious disadvantages in actual application: the lifting plate and the pressure rod occupy most of the space above the tooling, which makes it difficult for the staff to fully observe the structure and details of the chassis part during the detection of the chassis part, affecting the accuracy and efficiency of the detection. Due to space limitations, the staff often cannot effectively complete the operation. Therefore, a positioning tooling for automobile chassis part detection is proposed to solve the above problems. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is that in the prior art, the lifting plate and the pressure rod occupy most of the space above the tooling, which makes it difficult for the staff to fully observe the structure and details of the chassis part during the detection of the chassis part.

[0005] To solve the above technical problem, the technical solution of the utility model is to provide a positioning tooling for automobile chassis part detection, including a base. A row of grooves are formed in the base, and roller bodies are rotatably connected in the grooves. Positioning members are arranged on both sides of the base perpendicular to the axis of the roller bodies. The positioning members include a pair of convex blocks arranged on the base. A rotating rod is rotatably connected between the convex blocks. A positioning rod is arranged on the rotating rod. The positioning rod is located above the base. A row of pressure rods are arranged at the bottom of the positioning rod. The rotating rod can drive the positioning rod to rotate. First cylinders are arranged on both sides of the grooves on the base. The telescopic direction of the first cylinders is perpendicular to the axis of the roller bodies. The moving ends of the two first cylinders face each other, and clamping members are fixedly connected to the moving ends of the first cylinders. The first cylinders can push the clamping members to make them approach each other.

[0006] Optionally, the clamping member includes a fixing plate connected to the first cylinder. A groove is provided on the fixing plate. Through holes are provided on the opposite surfaces of the two clamping plates. A spring is provided in the groove. A T-shaped rod is connected to the spring, and one end of the T-shaped rod passes through the through hole.

[0007] Optionally, a connecting member and a driving block are fixedly connected to the rotating rod. The positioning rod is connected above the connecting member. The lower end of the driving block is connected to a second cylinder, and the second cylinder can drive the rotating rod to rotate through the driving block.

[0008] Optionally, a support block is provided below the base. A rotatable rectangular plate is provided on the support block. The second cylinder is fixedly connected to the rectangular plate.

[0009] Optionally, a short shaft is provided on the support block. The rectangular plate is inserted on the short shaft, and the rectangular plate can rotate around the short shaft.

[0010] Optionally, the connecting member includes a cylinder body sleeved on the rotating rod. A short rod is provided at the top of the cylinder body, and the short rod is fixedly connected to the end of the positioning rod.

[0011] Optionally, the positioning rod is in a "U" shape. A row of threaded holes is provided at the bottom of the positioning rod. The pressing rod is in a convex shape. An external thread is provided at one end of the pressing rod, and the pressing rod is threadedly connected to the threaded hole of the positioning rod.

[0012] Optionally, a silica gel sleeve is provided at the end of the pressing rod away from the positioning rod, and a rubber sleeve is provided on the outer surface of the roller body.

[0013] In summary, the present utility model has at least the following beneficial effects:

[0014] 1. By providing positioning members on both sides of the base, while completing the vertical positioning of the automotive chassis parts placed on the base, since the positioning members are located on both sides of the base, they do not occupy the space above the base, thus ensuring that the staff can fully observe the structure and details of the chassis parts during the detection process, improving the accuracy and efficiency of the detection.

[0015] 2. By providing a groove and a roller body on the base, after placing the chassis parts, the automatic centering function of the chassis parts is realized. There is no need for manual position adjustment. The first cylinder pushes the clamping member to move, and the clamping and positioning can be automatically completed. The setting of the roller body enables the chassis parts to achieve rolling contact during the movement process, effectively reducing the wear at the bottom of the chassis parts. Compared with the sliding friction between the chassis parts and the tooling in the traditional tooling, the rolling friction of the roller body greatly reduces the wear degree and extends the service life of the chassis parts.

Specific implementation mode

[0021] The following is a further detailed description of the present utility model in conjunction with Figures 1-4 to further elaborate on the present utility model.

[0022] The present utility model discloses a positioning tooling for detecting automotive chassis parts. Referring to Figure 1 , it includes a base 1. A row of grooves 101 are provided on the base 1. Roller bodies 102 are rotatably connected in the grooves 101. Positioning members 4 are provided on both sides of the base 1 perpendicular to the axis of the roller bodies 102. The positioning member 4 includes a pair of convex blocks 5 provided on the base 1. A rotating rod 6 is rotatably connected between the convex blocks 5. A positioning rod 8 is provided on the rotating rod 6. The positioning rod 8 is located above the base 1. A row of pressing rods 9 are provided at the bottom of the positioning rod 8. The rotating rod 6 can drive the positioning rod 8 to rotate. First cylinders 2 are provided on both sides of the grooves 101 on the base 1. The telescopic direction of the first cylinders 2 is perpendicular to the axis of the roller bodies 102. The moving ends of the two first cylinders 2 face each other, and clamping members 3 are fixedly connected to their moving ends. The first cylinders 2 can push the clamping members 3 and make them approach each other.

[0023] In a further implementation mode, the clamping member 3 includes a fixing plate. The fixing plate is connected to the first cylinder 2. A groove body 31 is provided on the fixing plate. Through holes are provided on the opposite surfaces of the two clamping plates 3. A spring is provided in the groove body 31. A T-shaped rod 33 is connected to the spring. One end of the T-shaped rod 33 passes through the through hole.

[0024] In a further implementation mode, referring to Figure 2 and Figure 3, a connecting piece 7 and a driving block 10 are connected to the rotating rod 6 by interference fit, the positioning rod 8 is connected above the connecting piece 7, and a second cylinder 11 is connected to the lower end of the driving block 10, and the second cylinder 11 can drive the rotating rod 6 to rotate through the driving block 10. A supporting block 103 is provided under the base 1, and a rotatable rectangular plate 104 is provided on the supporting block 103. The second cylinder 11 is fixedly connected to the rectangular plate 104, and a short shaft 105 is provided on the supporting block 103. The rectangular plate 104 is plugged into the short shaft 105, and the rectangular plate 104 can rotate around the short shaft 105. While the positioning piece 4 completes the vertical positioning of the automobile chassis part placed on the base 1, since the positioning piece 4 is located on both sides of the base, it will not occupy the space above the base, thereby ensuring that the staff can fully observe the structure and details of the chassis part during the detection process, thereby improving the accuracy and efficiency of the detection.

[0025] In a further embodiment, referring to Figure 4 The connecting member 7 includes a cylinder sleeved on the rotating rod 6 with an interference fit, and a short rod 71 is arranged on the top of the cylinder, and the short rod 71 is fixedly connected to the end of the positioning rod 8. The positioning rod 8 is in the shape of a "凵" shape, and a row of threaded holes is opened at the bottom of the positioning rod 8. The shape of the pressure rod 9 is convex, and one end of the pressure rod 9 is provided with an external thread. The pressure rod 9 is threadedly connected to the threaded hole of the positioning rod 8 to realize the installation and disassembly of the pressure rod 9. A silicone sleeve is provided on the end of the pressure rod 9 away from the positioning rod 8, which can reduce the friction with the contact point of the chassis part when positioning the chassis part, and reduce the wear on the surface of the chassis part. The outer surface of the roller body 102 is provided with a rubber sleeve. The setting of the roller body 102 enables the chassis part to achieve rolling contact during the movement, which effectively reduces the wear on the bottom of the chassis part. Compared with the sliding friction between the chassis part and the tooling in the traditional tooling, the rolling friction of the roller body 102 greatly reduces the degree of wear and extends the service life of the chassis part.

[0026] When the utility model is in use, firstly, the electrical equipment in the device is connected to an external power supply and switch, and the chassis part to be detected is placed on the base 1 and contacts the roller body 102. At this time, the switch of the first cylinder 2 is turned on to make it work synchronously. The first cylinder 2 works to push the clamping member 3 to move. Under the push of the two clamping members 3, the chassis part moves on the roller body 102 to center it and complete the positioning in the horizontal direction. After the horizontal positioning is completed, the switch of the second cylinder 11 is turned on to make it work. The second cylinder 11 works to push the driving block 10 to make an arc movement. The movement of the driving block 10 drives the rotating rod 6 to rotate. The rotation of the rotating rod 6 causes the connecting member 7 to rotate. The rotation of the connecting member 7 drives the positioning rod 8 to rotate, so that the pressure rod 9 contacts the top surface of the chassis part to complete the positioning of the top of the chassis part.
