Description

Technical Field

[0001] The utility model relates to a clamp, in particular to a shell processing clamp. Background Art

[0002] During the processing of the shell, a clamp is often needed to clamp the workpiece. The clamps currently used are divided into two modes: manual adjustment and electric adjustment. At the same time, the manual mode will not cause excessive extrusion on the workpiece surface, but the speed and efficiency are slow. The electric adjustment speed is fast, but if the adjustment is not in place, it will cause excessive clamping on the shell surface and damage the shell. Therefore, a new type of clamp that will not damage the shell and clamp quickly is needed. Utility Model Content

[0003] The purpose of the utility model is to provide a shell processing fixture to solve the above technical problems.

[0004] To achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A shell processing fixture includes a supporting shell, a replaceable clamping block, an adjusting lever, an operating button, and an adjusting handwheel. The supporting shell is a four-sided rectangular structure with symmetrically distributed replaceable clamping blocks installed on the inner side of the top groove, an embedded slidingly connected adjusting lever is installed in the middle of the front end of the supporting shell, embedded symmetrically distributed operating buttons are installed on the left side of the adjusting lever, and an articulated adjusting handwheel is installed on the right end of the supporting shell.

[0006] On the basis of the above technical solution, the replaceable clamping blocks are of symmetrical distribution structure and are installed with bolt-fixed connecting blocks at the bottom, and movable nuts fixed with bolts are installed on the inner side of the connecting blocks. The two sets of movable nuts are nested on the surface of the bidirectional screw and connected by threads. The right-end driven gear and the left-end driven gear are welded and fixed on both sides of the bidirectional screw and are hingedly installed on the inner side of the supporting shell through the first bearing. The front ends of the bidirectional screw and the right-end driven gear and the left-end driven gear are installed with conversion devices.

[0007] On the basis of the above technical scheme, the conversion device includes a transmission shaft, a right-end driving gear, a left-end driving gear, a hexagonal shaft, a shaft plug-in sleeve, a servo motor, a clamping guide frame, a second bearing, and a guide rail. The right-end driving gear and the left-end driving gear are welded and fixed on both sides of the transmission shaft. The right-end driving gear and the left-end driving gear are welded and fixed on both sides. The two groups of hexagonal shafts are installed with plug-in shaft plug-in sleeves on both sides. The two groups of plug-in shaft sleeves are respectively connected to the adjusting hand wheel and the servo motor. The circumferential surface of the transmission shaft is installed with a clamping guide frame and is hingedly connected through the second bearing. The front end bottom of the clamping guide frame is installed with a welded adjustment lever and the middle of the bottom is installed with an embedded sliding connection guide rail.

[0008] Compared with the prior art, the utility model has the following advantages: the clamp of the utility model combines manual adjustment and electric adjustment and cooperates with the adjustment lever to perform mode conversion, which can not only achieve rapid clamping of the shell but also will not cause damage to the surface of the shell, effectively improving the efficiency and quality of clamping, and at the same time can quickly replace the clamping block or claw, further reducing the time for repair and maintenance.

DETAILED DESCRIPTION

[0013] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0014] like Figure 1-3 As shown, a shell processing fixture includes a supporting shell 1, a replaceable clamping block 2, an adjusting lever 3, an operating button 4, and an adjusting handwheel 5. The supporting shell 1 is a four-sided rectangular structure and the replaceable clamping block 2 is symmetrically installed on the inner side of the top groove. An embedded slidingly connected adjusting lever 3 is installed in the middle of the front end of the supporting shell 1, and embedded symmetrically distributed operating buttons 4 are installed on the left side of the adjusting lever 3. The right end of the supporting shell 1 is installed with a hingedly connected adjusting handwheel 5.

[0015] The replaceable clamping block 2 is a symmetrical distribution structure and is installed with a bolt-fixed connecting block 6 at the bottom. A bolt-fixed moving nut 7 is installed inside the connecting block 6. The two sets of moving nuts 7 are nested on the surface of the bidirectional screw 8 and connected by threads. The right-end driven gear 9 and the left-end driven gear 10 are welded and fixed on both sides of the bidirectional screw 8 and are hingedly installed on the inner side of the supporting shell 1 through the first bearing 11. The front ends of the bidirectional screw 8 and the right-end driven gear 9 and the left-end driven gear 10 are installed with a conversion device 12.

[0016] The conversion device 12 includes a transmission shaft 13, a right-end driving gear 14, a left-end driving gear 15, a hexagonal shaft 16, a shaft inserting sleeve 17, a servo motor 18, a clamping guide frame 19, a second bearing 20, and a guide rail 21. The right-end driving gear 14 and the left-end driving gear 15 are welded and fixed on both sides of the transmission shaft 13. The right-end driving gear 14 and the left-end driving gear 15 are welded and fixed on both sides. The two groups of hexagonal shafts 16 are installed on both sides with plug-in shaft inserting sleeves 17. The two groups of plug-in shaft sleeves 17 are respectively connected to the adjusting hand wheel 5 and the servo motor 18. The circumferential surface of the transmission shaft 13 is installed with a clamping guide frame 19 and is hingedly connected through the second bearing 20. The front end bottom of the clamping guide frame 19 is installed with a welded adjustment lever 3 and the middle of the bottom end is installed with an embedded sliding connection guide rail 21.

[0017] The working principle of the utility model is as follows: when it is necessary to clamp the workpiece, the adjusting lever is first moved to the left, and at the same time, the clamping guide frame is driven to translate to the left along the guide rail during the movement of the adjusting lever, and then the clamping guide frame drives the transmission shaft to move and the hexagonal shaft at the right end of the transmission shaft is disconnected from the plug-in shaft sleeve connected to the adjusting hand wheel, and then the hexagonal shaft at the left end of the transmission shaft is plug-in connected to the plug-in shaft sleeve connected to the servo motor, and then the servo motor drives the plug-in shaft sleeve, the hexagonal shaft, the left end driving gear and the transmission shaft to rotate, and then the left end driving gear is meshed with the left end driven gear at the rear end to drive the bidirectional lead screw to rotate, and then the bidirectional lead screw cooperates with the moving nut to rotate the servo motor The movement is transformed into two sets of connecting blocks and replaceable clamping blocks in two-way horizontal movement to realize rapid clamping of the shell. Then, when the replaceable clamping block is about to contact with the shell, the servo motor is turned off by operating the button and the adjusting lever is operated to move to the far right. Similarly, the plug-in shaft sleeve at the right end of the servo motor is disengaged from the hexagonal shaft at the left end of the transmission shaft, and then the hexagonal shaft at the right end of the transmission shaft is plug-connected with the plug-in shaft sleeve on the left side of the adjusting handwheel. The right-end driving gear at the right end of the transmission shaft is meshed with the right-end driven gear at the front end, and then the clamping force of the shell is controlled by rotating the adjusting handwheel, which ensures the clamping effect while improving the clamping efficiency. The connecting block and the replaceable clamping block are fixed by two sets of bolts for easy replacement.

[0018] The above is a preferred embodiment of the present invention. For ordinary technicians in this field, according to the teachings of the present invention, without departing from the principles and spirit of the present invention, changes, modifications, substitutions and variations made to the implementation methods are still within the scope of protection of the present invention.
