Description

Technical Field

[0001] This utility model relates to the technical field of connecting rod processing devices, and specifically discloses a tooling positioning and clamping device for grinding connecting rod teeth. Background Technology

[0002] Connecting rods are rigid rods that connect the piston and crankshaft at both ends. Their working principle is to transmit the force received by the piston to the crankshaft, thereby converting the reciprocating motion of the piston into the rotational motion of the crankshaft. They are widely used in internal combustion engines, presses, engineering machinery and other fields. During the machining process of connecting rods, tooth grinding is required.

[0003] When dealing with connecting rods with asymmetrical tooth profiles, existing tooth grinding devices require adjustments and replacements to their structure and position. They are often not easy to directly grind the connecting rod's teeth, and the clamping process can easily cause deformation of the connecting rod, resulting in insufficient tooth profile fit. Utility Model Content

[0004] In view of the shortcomings of the prior art, the present invention provides a tooling positioning and clamping device for connecting rod tooth profile grinding, which can quickly position and clamp the connecting rod, facilitate loading and unloading, and avoid deformation of the connecting rod during the positioning and clamping process, thereby improving the tooth profile fit.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] The tooling positioning and clamping device for connecting rod tooth profile grinding includes a clamping body, on both sides of which a connecting rod cover and a connecting rod body are respectively provided. Several positioning blocks are fixedly provided on both sides of one end of the clamping body, and several hydraulic clamping devices are fixedly provided on both sides of the other end of the clamping body in conjunction with several positioning blocks. A pressing block is fixedly provided on the end of the hydraulic clamping device near the positioning block.

The positioning blocks can abut against the opposite sides of the connecting rod cover and the connecting rod body.

[0007] Furthermore, six sets of positioning blocks are provided, and three sets of positioning blocks are provided on each side of the clamping body. Six sets of hydraulic clamping devices and clamping blocks are provided in coordination, and three sets of hydraulic clamping devices and three sets of clamping blocks are provided on each side of the clamping body.

[0008] Furthermore, the connecting rod cover has an inner hole, and a positioning shaft is installed through the inner hole on the upper part of the clamping body. The positioning shaft can position the inner hole.

[0009] Furthermore, the positioning shaft and the clamping body are interference fits.

[0010] Furthermore, a small hole is provided at the bottom of the connecting rod body, and a positioning shaft two is fixedly installed on the bottom of the clamp body near the connecting rod body in conjunction with the small hole. The positioning shaft two can position the small hole.

[0011] Furthermore, the positioning shaft and the clamping body are fixedly connected by screws.

[0012] Furthermore, a positioning block two is fixedly installed on the side of the clamp body near the connecting rod cover, which can position the connecting rod cover.

[0013] Furthermore, the second positioning block is fixedly connected to the clamping body by screws.

[0014] Furthermore, a positioning block three is fixedly installed on the side of the clamp body near the connecting rod body, which can position the large end of the connecting rod body.

[0015] Furthermore, the positioning block three is fixed to the connecting clamp body by screws.

[0016] The beneficial effects of this utility model are:

[0017] This invention, by setting several positioning blocks and several clamping blocks to abut against the connecting rod cover and connecting rod body, can quickly position and clamp the connecting rod cover and connecting rod body, making it convenient for loading and unloading. The contact area between the positioning blocks and the connecting rod cover and connecting rod body is small, and the clamping blocks are in point contact with the connecting rod cover and connecting rod body, which can avoid the deformation of the connecting rod cover and connecting rod body during the positioning and clamping process, thereby improving the tooth profile fit.

[0026] Example 1

[0027] like Figure 1-6 As shown, the tooling positioning and clamping device for connecting rod tooth profile grinding includes a clamping body 1. The clamping body 1 has a connecting rod cover 2 and a connecting rod body 3 respectively on both sides. Several positioning blocks 4 are fixedly arranged on both sides of one end of the clamping body 1. Several hydraulic clamping devices 5 are fixedly arranged on both sides of the other end of the clamping body 1, in conjunction with the positioning blocks 4. A pressing block 6 is fixedly arranged at the end of the hydraulic clamping device 5 near the positioning blocks 4. The pressing blocks 6 can abut against the opposite sides of the connecting rod cover 2 and the connecting rod body 3. The end of the pressing block 6 abutting against the connecting rod cover 2 and the connecting rod body 3 has a hemispherical structure. The positioning blocks 4 can abut against the opposite sides of the connecting rod cover 2 and the connecting rod body 3.

[0028] This utility model, by setting several positioning blocks 4 and several clamping blocks 6 to abut against the connecting rod cover 2 and the connecting rod body 3, can quickly position and clamp the connecting rod cover 2 and the connecting rod body 3, making it convenient for loading and unloading. The contact area between the positioning blocks 4 and the connecting rod cover 2 and the connecting rod body 3 is small, and the clamping blocks 6 have point contact with the connecting rod cover 2 and the connecting rod body 3, which can avoid the deformation of the connecting rod cover 2 and the connecting rod body 3 during the positioning and clamping process, thereby improving the tooth profile fit.

[0029] Six sets of positioning blocks 4 are provided, and three sets of positioning blocks 4 are provided on each side of the clamping body 1. Six sets of hydraulic clamping devices 5 and three sets of clamping blocks 6 are also provided on each side of the clamping body 1. When clamping and positioning the connecting rod cover 2 and the connecting rod body 3, the clamping blocks 6 must be aligned with the positioning blocks 4 to prevent deformation of the connecting rod cover 2 and the connecting rod body 3.

[0030] The connecting rod cover 2 has an inner hole, and the upper part of the clamp body 1 is fitted with a positioning shaft 7 through the inner hole. The positioning shaft 7 can position the inner hole.

[0031] The positioning shaft 7 and the fixture body 1 are interference fit.

[0032] A small hole is provided at the bottom of the connecting rod body 3. A positioning shaft 8 is fixedly installed on the bottom of the clamp body 1 near the connecting rod body 3 in conjunction with the small hole. The positioning shaft 8 can position the small hole.

[0033] The positioning shaft 2 8 and the clamping body 1 are fixedly connected by screws 9.

[0034] The clamp body 1 is fixedly provided with a positioning block 2 10 on the side near the connecting rod cover 2, which can position the connecting rod cover 2.

[0035] Positioning block 2 10 is fixed to the connecting clamp 1 by screw 9.

[0036] With the above settings, positioning block 210 positions the connecting rod cover 2, and positioning shaft 7 positions the inner hole, thereby achieving pin positioning on both sides of the connecting rod cover 2 and ensuring the stability of the connecting rod cover 2 during the tooth grinding process.

[0037] The clamp body 1 is fixedly provided with a positioning block 3 11 on the side near the connecting rod body 3. The positioning block 3 11 can position the large end of the connecting rod body 3.

[0038] Positioning block 311 is fixed to the connecting clamp 1 by screw 9.

[0039] With the above settings, positioning block 3 11 positions the large end of connecting rod 3, and positioning shaft 2 8 positions the small hole, thereby achieving two-sided pin positioning of connecting rod 3 and ensuring the stability of connecting rod 3 during tooth grinding.

[0040] Working principle and process:

[0041] In operation, this invention first installs the connecting rod cover 2 on one side of the clamp body 1. The side of the connecting rod cover 2 closest to the clamp body 1 contacts three sets of positioning blocks 4, forming a positioning surface. The outer side of the connecting rod cover 2 is positioned by positioning block 10, and the inner hole is positioned by positioning shaft 7, achieving pin positioning on both sides of the connecting rod cover 2. Then, the connecting rod body 3 is installed on the other side of the clamp body 1. The side of the connecting rod body 3 closest to the clamp body 1 contacts three sets of positioning blocks 4, forming a positioning surface. The outer side of the large end of the connecting rod body 3 is positioned by positioning block 11, and the small hole is positioned by positioning shaft 7. Positioning is performed using the second 8, achieving two-sided pin positioning of the connecting rod body 3. After installing the connecting rod cover 2 and the connecting rod body 3, the six sets of hydraulic clamping devices 5 on both sides of the clamping body 1 are activated, so that the six sets of clamping blocks 6 respectively clamp the connecting rod cover 2 and the connecting rod body 3. During the clamping process, the six sets of clamping blocks 6 must be aligned with the six sets of positioning blocks 4 to prevent deformation of the connecting rod cover 2 and the connecting rod body 3. After the clamping and positioning work is completed, the tooth profile grinding work begins. After the tooth profile grinding work is completed, the hydraulic clamping devices 5 are released, and the connecting rod cover 2 and the connecting rod body 3 are removed, thus completing one tooth profile grinding process.
