Description

Technical Field

[0001] The utility model relates to the technical field of connecting rod arm processing, in particular to a clamping and positioning device for connecting rod arm processing. Background Art

[0002] When clamping and processing a connecting rod arm, the thickness difference between the two end hole walls shall not exceed 1.5 mm. Since it is difficult to ensure the consistency of the product length of the casting blank, the wall thickness difference between the two holes after processing and the blank wall will surely be affected.

[0003] By rotating the nut (M20 positive and reverse threads) clockwise and counterclockwise and the transmission shaft connected thereto, the V-shaped block for positioning is synchronously translated to realize synchronous positioning and clamping of the workpiece. The nut is manually rotated and the workpiece is positioned and pressed by a manual pressing plate to make the transmission support and the transmission shaft hole of the transmission shaft frictionally transmit torque. The frictional resistance is large, the translation is not smooth, the labor intensity of workers is high, the auxiliary time is long, and the efficiency is low.

[0004] Therefore, in view of the deficiencies of the prior art, it is very necessary to provide a clamping and positioning device for connecting rod arm processing to solve the deficiencies of the prior art. Summary of the Utility Model

[0005] The purpose of the utility model is to avoid the deficiencies of the prior art and provide a clamping and positioning device for connecting rod arm processing. The connecting rod arm workpiece to be processed is clamped and positioned by the cooperation of the positioning mechanism and the clamping plate arranged on the workpiece processing table. By operating the two-position five-way hand-operated valve in the positioning mechanism, the synchronous finger cylinders arranged at both ends drive the connecting block and the transmission shaft, so that the positioning block moves to laterally clamp the connecting rod arm workpiece to be clamped, reducing the labor intensity of workers and reducing the clamping auxiliary time. While meeting the technical requirements and ensuring the reliable product quality, the working efficiency is improved.

[0006] The above object of the utility model is achieved by the following technical means.

[0007] Provide a clamping and positioning device for connecting rod arm processing, including a workpiece processing table, a positioning mechanism is arranged at the bottom of the workpiece processing table, two groups of hydraulic cylinders are arranged at the top of the positioning mechanism, and clamping plates are respectively installed on the hydraulic cylinders;

[0034] Embodiment 1

[0035] As Figures 1-2 shown, a clamping and positioning device for connecting rod arm processing includes a workpiece processing table 1. A positioning mechanism 2 is provided at the bottom of the workpiece processing table 1. Two groups of hydraulic cylinders 3 are provided at the top of the positioning mechanism 2, and clamping plates 4 are respectively installed on the hydraulic cylinders 3.

[0036] After installing the connecting rod arm workpiece to be constructed on the workpiece processing table 1, it is vertically clamped by the hydraulic cylinders 3 and the clamping plates 4. At the same time, the two transverse ends of the connecting rod arm workpiece can be positioned and clamped by the positioning mechanism 2.

[0037] The positioning mechanism 2 includes a two-position five-way hand-operated valve 5. The two-position five-way hand-operated valve 5 is installed at the bottom end of the workpiece processing table 1. Synchronous finger cylinders 6 are respectively installed at both ends of the two-position five-way hand-operated valve 5. A connecting block 7 is provided on the synchronous finger cylinder 6. A transmission shaft 8 is installed on the connecting block 7. The end of the transmission shaft 8 is connected to a positioning block 9, and a guide seat 10 is installed beside the positioning block 9.

[0038] When using the positioning mechanism 2, operate the two-position five-way hand-operated valve 5 to control the telescopic movement of the synchronous finger cylinders 6 installed at both ends of the two-position five-way hand-operated valve. The synchronous finger cylinders 6 can drive the connecting block 7 to move. When the rotating shaft installed on the connecting block 7 transmits power, the positioning block 9 displaces, so that the positioning block 9 moves horizontally on the guide seat 10 to position and clamp the connecting rod arm to be processed.

[0039] The guide seat 10 includes a seat body 11. The seat body 11 is installed at both ends of the workpiece processing table 1. Two groups of guide rods 14 are integrally formed on the seat body 11. The two groups of guide rods 14 are installed in parallel. The seat body 11 is fixed at both ends of the workpiece processing table 1. The guide rods 14 installed on the seat body 11 penetrate into the positioning block 9, which can play a guiding role in the movement of the guide seat 10 and improve the accuracy of the movement of the guide seat 10.

[0040] A V-shaped positioning groove 12 is provided on the positioning block 9. The bottom end of the positioning block 9 is connected to the transmission shaft 8. Two groups of positioning holes 13 are provided inside the positioning block 9. The V-shaped positioning groove 12 can clamp the connecting rod arm to be processed.

[0041] A limiting plate 15 is arranged on the transmission shaft 8 between the positioning block 9 and the connecting block 7. The limiting plate 15 is threadedly installed on the workpiece processing plate. The limiting plate 15 can limit the transmission shaft 8 to prevent the transmission shaft 8 from deviating, ensure the linear movement of the transmission shaft 8, and ensure the horizontal movement and clamping of the guide seat 10.

[0042] During the production process, the positioning mechanism 2 arranged on the workpiece processing table 1 cooperates with the clamping plate 4 to clamp and position the connecting rod arm workpiece to be processed. By operating the two-position five-way hand-operated valve 5 in the positioning mechanism 2, the synchronous finger cylinders 6 arranged at both ends drive the connecting block 7 and the transmission shaft, so that the positioning block 9 moves to horizontally clamp the connecting rod arm workpiece to be clamped, reducing the labor intensity of workers and the auxiliary clamping time. While meeting the technical requirements and ensuring the reliable product quality, the work efficiency is improved.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit the protection scope of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the essence and scope of the technical solutions of the present invention.
