Description

Technical Field

[0001] The utility model belongs to the technical field of automobile connecting rod processing equipment, and more specifically, particularly relates to automobile connecting rod grinding equipment. Background Art

[0002] The function of the automobile connecting rod is to transmit the force borne by the piston to the crankshaft and convert the reciprocating motion of the piston into the rotational motion of the crankshaft. The connecting rod mechanism of the automobile is a rod member whose two ends are respectively hinged with the active and driven components to transmit motion and force. For example, in reciprocating piston power machinery and compressors, connecting rods are used to connect the piston and the crank. The connecting rod is mostly a steel part, and the cross section of its main part is mostly circular or I-shaped. There are holes at both ends, and bronze bushings or needle bearings are installed in the holes for the shaft pin to be installed to form a hinge. The connecting rod is an important part in the automobile engine. It connects the piston and the crankshaft, and its function is to convert the reciprocating motion of the piston into the rotational motion of the crankshaft.

[0003] In the prior art, when grinding automobile connecting rods, the grinding process is performed by machine tools. Although the grinding work can be completed quickly, it is necessary to manually turn over and fix the connecting rod for a second time after grinding one side, and then grind the other side. The grinding speed needs to be improved, and the debris generated by the grinding is scattered on the fixing table, which needs to be cleaned frequently by humans.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and an automobile connecting rod grinding device is provided to achieve a more practical purpose. Utility Model Content

The telescopic ends of the two electric telescopic rods 407 are fixedly connected to the wall of the rectangular block 408 on the same side. The upper ends of the opposite surfaces of the two clamp limit blocks 406 are clamped with clamp connectors 405, and the middle parts of the other sides of the two clamp connectors 405 are clamped with T-shaped rotating blocks 403. On the right wall of the left T-shaped rotating block 403 A connecting rod small end clamp 401 is fixedly provided, a connecting rod big end clamp 402 is fixedly provided on the left side wall of the right T-shaped rotating block 403, a second motor 409 is installed on the upper wall of the right clamping base 301, the working end of the second motor 409 passes through the middle of the upper end of the clamp limit block 406 on the same side and is fixedly connected to the middle of the right side wall of the clamp connecting head 405 on the same side, a support block 404 installed on the clamping base 301 is also provided between the connecting rod small end clamp 401 and the connecting rod big end clamp 402 and the clamp limit block 406 on the same side, and a rotating groove matching the T-shaped rotating block 403 is opened at the upper end.

[0033] On it, first select the matching connecting rod small end clamp 401 and connecting rod large end clamp 402 according to the specifications of the connecting rod body 2. After selecting the matching connecting rod small end clamp 401 and connecting rod large end clamp 402, pass them through the support block 404 and fix them on the clamp connector 405. Then, according to the length of the connecting rod body 2, slide and adjust the distance between the two clamping bases 301 on the support platform 307 to achieve the purpose of clamping connecting rod bodies 2 of different models. At this time, the electric telescopic rod 407 is extended, so that the clamp limit block 406 clamps and fixes the clamp connector 405, and then use the grinder 1 to start processing one side of the connecting rod body 2.

[0037] As attached Figure 1 and attached Figure 5 As shown, in some embodiments, a T-shaped block is fixedly provided on the bottom surface of the clamp limit block 406, and the T-shaped block is slidably arranged in a T-shaped slide groove opened in the middle of the upper surface of the clamping base 301. The purpose of setting the T-shaped block and the T-shaped slide groove is to cooperate with the clamp limit block 406 to slide left and right while limiting its up and down movement.

[0038] As attached Figure 1 and attached Figure 2 As shown, in some embodiments, a debris collection box 5 is fixedly provided on the bottom surface of the support platform 307 for collecting fallen debris during the processing.

[0039] As attached Figure 1 To Attachment Figure 5 As shown, in some embodiments, dust shielding plates are fixedly installed on the lower ends of the left and right side walls of the clamp limit block 406. During the processing and grinding process, debris splashes everywhere, and the dust shielding plates are used to block the debris and prevent the debris from falling into the T-shaped slide groove and affecting the left and right sliding of the clamp limit block 406.

[0040] The specific usage and function of this embodiment are as follows: first, according to the specifications of the connecting rod body 2, the connecting rod small end clamp 401 and the connecting rod large end clamp 402 are selected, and after the connecting rod small end clamp 401 and the connecting rod large end clamp 402 are selected, they are passed through the support block 404 and clamped in the clamp connector 405, and the T-shaped rotating block 403 is fixed by screws so that the connecting rod small end clamp 401 and the connecting rod large end clamp 402 are fixed, and then the first motor 306 is controlled to rotate according to the length of the connecting rod body 2, so that the two internal thread blocks 302 on the bidirectional threaded rod 303 slide closer to or away from each other, and then the distance between the two clamping bases 301 on the support platform 307 is adjusted to achieve the purpose of clamping the connecting rod body 2;

[0041] By controlling the electric telescopic rod 407 to extend, the clamp limit block 406 clamps and fixes the clamp connector 405, and then the grinder 1 is used to start processing one side of the connecting rod body 2. When the other side of the connecting rod body 2 needs to be processed, the electric telescopic rod 407 is controlled to retract and reset, pulling the clamp limit block 406 away from the clamp connector 405 to disengage it, and the second motor 409 on the right side is used to rotate the connecting rod small end clamp 401, the connecting rod large end clamp 402 and the connecting rod body 2 clamped therebetween to rotate half a circle, thereby realizing the turning over of the connecting rod body 2. At this time, the electric telescopic rod 407 is extended to drive the clamp limit block 406 to approach the clamp connector 405 and clamp it, thereby limiting the rotation of the connecting rod small end clamp 401, the connecting rod large end clamp 402 and the connecting rod body 2, and then the connecting rod body 2 is grinded by the grinder 1.
