Description

Technical Field

[0001] The utility model belongs to the technical field of bearing processing, in particular to an adjustable clamping tool for bearing processing. Background Art

[0002] Bearings are an important component in contemporary mechanical equipment. When processing bearings, clamping tools are usually used to position the bearing components to improve processing stability.

[0003] At present, relatively movable clamps are usually used to position bearings. The clamped surface of the bearing component will be blocked. After the inner or outer wall of the bearing component is processed, the clamping tooling needs to be replaced to position the bearing component so that the blocked surface is exposed to the outside, and then the bearing component is processed. Such complicated operations greatly affect the processing efficiency of the bearing component, the labor intensity is high, and the flexibility of the clamping tooling is poor. Utility Model Content

[0004] In order to overcome the above-mentioned defects, the utility model provides an adjustable clamping tool for bearing processing, which solves the problem that the clamped surface of the bearing component will be blocked. After the inner wall or outer wall processing of the bearing component is completed, the clamping tool needs to be replaced to position the bearing component so that the blocked surface is exposed to the outside before the bearing component can be processed.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an adjustable clamping tool for bearing processing, comprising a support seat, on which two groups of inner ring clamps and outer ring clamps are arranged, the bottoms of the inner ring clamps and the outer ring clamps are respectively hinged with connecting rods 1 and 2 through pins, the bottoms of the connecting rods 1 and 2 are adjusted with supporting plates through pins, a cavity is opened in the support seat, the supporting plate is slidably connected in the cavity, and a supporting assembly is installed in the middle of the supporting plate;

[0006] The support assembly includes a bolt, the external thread of the bolt is connected to a nut, the nut is clamped in the middle of the support plate, bearings are respectively provided at both ends of the bolt, the bearings are clamped in the cavity, a bevel gear 1 is clamped on the outer lower part of the bolt, an adjustment assembly is connected to the bevel gear 1, and the adjustment assembly passes through the support seat.

[0007] As a further solution of the utility model: the number of the inner ring clamps and the outer ring clamps is four respectively, and the positions of the support seat corresponding to the four inner ring clamps and the four outer ring clamps are respectively provided with a slideway 1 and a slideway 2.

[0008] As a further solution of the utility model: four limiting rods are arranged through the support plate, and two ends of the limiting rods are fixed to the inner wall of the cavity.

[0009] As a further solution of the utility model: four through holes are provided at the bottom of the support base, and two mounting holes are provided on both sides outside the support base.

[0010] As a further solution of the utility model: the adjustment component includes a connecting shaft, one end of the connecting shaft is fixedly connected to a second bevel gear, and the second bevel gear is meshed with the first bevel gear.

[0011] As a further solution of the utility model: two fixing blocks are provided through the outside of the connecting shaft, the fixing blocks are fixed to the bottom of the cavity, and a rotating handle is fixed to one end of the connecting shaft away from the second bevel gear.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The adjustable clamping tool for bearing processing places the bearing component on a support seat so that it is located between the inner ring clamping plate and the outer ring clamping plate, and drives the bolt to rotate by rotating the adjusting component. During the rotation of the bolt, the nut can drive the support plate to move upward, and the support plate can push the connecting rod 1 and the connecting rod 2 to rotate, so that the four connecting rods 1 respectively drive the four inner ring clamping plates to move away from each other, so that the inner ring clamping plate can fit tightly with the inner wall of the bearing component, so as to achieve the purpose of positioning the bearing component. When the processing of the outer ring of the bearing component is completed, the adjusting component is rotated in the opposite direction. Similarly, the support plate pulls the inner ring clamping plate and the outer ring clamping plate through the connecting rod 1 and the connecting rod 2, and the four outer ring clamping plates are close to each other to position the outer ring of the bearing component, so that the inner ring of the bearing component is exposed to the outside, which is convenient for processing. Therefore, the purpose of positioning the inner wall or outer wall of the bearing component is achieved by adjusting the position of the support plate, and there is no need to replace the clamping tool for operation, which greatly improves the processing efficiency of the bearing component and improves the flexibility of use of the clamping tool.

[0014] 2. The adjustable clamping tool for bearing processing drives the connecting shaft to rotate by turning the handle, and the connecting shaft drives the bevel gear one to rotate through the bevel gear two. The bolt can be adjusted easily by changing the direction of force transmission. When the outer ring clamp and the inner ring clamp are adjusted by the support plate, the outer ring clamp and the inner ring clamp can move synchronously to improve the stability of the clamping of the bearing component. When the inner ring clamp clamps the bearing component, the corresponding outer ring clamp is away from the bearing component. Similarly, when the outer ring clamp clamps the bearing component, the inner ring clamp is away from the bearing component, which will not cause space obstacles to the processing of the bearing component and improve the use effect of the clamping tool.

DETAILED DESCRIPTION

[0020] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0021] like Figure 1-4 As shown, the utility model provides a technical solution: an adjustable clamping tool for bearing processing, comprising a support seat 1, four through holes 13 are opened at the bottom of the support seat 1, and two mounting holes 14 are respectively opened on both sides of the outside of the support seat 1. Due to the through holes 13, the debris generated by the bearing component processing is conveniently discharged from the support seat 1, and due to the mounting holes 14, the support seat 1 is conveniently fixed on the processing table;

[0022] Two groups of inner ring clamps 2 and outer ring clamps 3 are arranged on the support seat 1, and the number of the inner ring clamps 2 and the number of the outer ring clamps 3 are four respectively. The positions corresponding to the four inner ring clamps 2 and the four outer ring clamps 3 on the support seat 1 are respectively provided with a slideway 1 8 and a slideway 2 9. By arranging the slideway 1 8 and the slideway 2 9, the slideway 1 8 and the slideway 2 9 can support and limit the inner ring clamps 2 and the outer ring clamps 3, thereby improving the stability of the inner ring clamps 2 and the outer ring clamps 3 in clamping the bearing components;

[0023] The bottom of the inner ring clamp 2 and the outer ring clamp 3 are respectively hinged with a connecting rod 1 4 and a connecting rod 2 5 through a pin shaft. The bottom ends of the connecting rod 1 4 and the connecting rod are adjusted with a support plate 6 through a pin shaft. Four limit rods 12 are arranged through the support plate 6. The two ends of the limit rods 12 are fixed to the inner wall of the cavity 7. Because the limit rods 12 are provided and because the limit rods 12 pass through the support plate 6, the support plate 6 will not rotate freely in the cavity 7, thereby improving the stability of the movement of the support plate 6.

[0024] A cavity 7 is provided in the support seat 1, a support plate 6 is slidably connected in the cavity 7, and a support assembly 10 is installed in the middle of the support plate 6;

[0025] The support assembly 10 includes a bolt 101, which is externally threaded with a nut 102. The nut 102 is clamped in the middle of the support plate 6. Bearings 104 are respectively provided at both ends of the bolt 101. Due to the bearings 104, the bolt 101 will not shake during rotation and will be more stable, thereby improving the stability of the nut 102 on the bolt 101 supporting the support plate 6.

[0026] The bearing 104 is clamped in the cavity 7, and a bevel gear 103 is clamped outside and below the bolt 101. The bevel gear 103 is connected to an adjustment component 11, which passes through the support seat 1. The adjustment component 11 includes a connecting shaft 111, and one end of the connecting shaft 111 is fixedly connected to a bevel gear 2 112. The bevel gear 2 112 is meshed with the bevel gear 103. Through the mutual cooperation between the bevel gear 103 and the bevel gear 2 112, the nut 102 on the bolt 101 is conveniently adjusted by changing the force transmission direction;

[0027] Two fixing blocks 113 are provided outside the connecting shaft 111, and the fixing blocks 113 are fixed at the bottom of the cavity 7. A turning handle 114 is fixed to the end of the connecting shaft 111 away from the bevel gear 2 112. The connecting shaft 111 is supported by the fixing blocks 113 to prevent the stability of the adjustment of the bevel gear 2 112 from being affected by the excessive length of the connecting shaft 111.

[0028] The working principle of the utility model is:

[0029] When in use, place the bearing component on the support seat 1 so that it is located between the inner ring clamping plate 2 and the outer ring clamping plate 3. Turn the handle 114 to drive the connecting shaft 111 to rotate. The connecting shaft 111 drives the bevel gear 1 103 to rotate through the bevel gear 2 112. The bevel gear 103 drives the bolt 101 to rotate. During the rotation of the bolt 101, the nut 102 can be used to drive the support plate 6 to move upward. The support plate 6 can push the connecting rod 1 4 and the connecting rod 2 5 to rotate, so that the four connecting rods 1 4 respectively drive the four inner ring clamping plates 2 away from each other, so that the inner ring clamping plate 2 can be clamped with the inner wall of the bearing component. When clamping the outer ring of the bearing component, rotate the handle 114 in the opposite direction. Similarly, the support plate 6 pulls the inner ring clamping plate 2 and the outer ring clamping plate 3 through the connecting rod 1 4 and the connecting rod 2 5. The four outer ring clamping plates 3 approach each other to clamp the outer ring of the bearing component.

[0030] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0031] The above describes in detail the preferred implementation of this patent, but this patent is not limited to the above implementation. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of this patent.
