Description

Technical Field

[0001] The utility model relates to the technical field of cylinder tooling, in particular to a cylinder fixing tooling. Background Art

[0002] The cylinder is a cylindrical metal part that guides the piston to perform linear reciprocating motion in the cylinder. The air in the engine cylinder converts heat energy into mechanical energy by expansion; the gas in the compressor cylinder is compressed by the piston to increase the pressure. The shell of turbines, rotary piston engines, etc. are also usually called "cylinders". The application fields of cylinders include: printing (tension control), semiconductors (spot welding machines, chip grinding), automatic control, robots, etc.

[0003] During the processing of existing cylinders, it is often necessary to use fixed tooling to clamp and fix the cylinder to facilitate subsequent processing operations on the cylinder. However, in the process of clamping and fixing the cylinder, it is generally necessary to manually support the cylinder and then clamp and fix the cylinder through a clamping structure. Since manual support of the cylinder may cause shaking, hand shaking can easily cause the cylinder to tilt or shift, which can easily cause the cylinder to tilt or shift after clamping and fixing, affecting the processing effect of the cylinder. Moreover, when clamping and fixing the cylinder, it is impossible to accurately know the clamping force. If the clamping force is too large, it is easy to cause damage to the cylinder. If the clamping force is insufficient, it is easy to cause the cylinder to loosen. Therefore, how to quickly position and install the cylinder and how to clamp and fix the cylinder with accurate and appropriate force need to be improved. Utility Model Content

[0008] Furthermore, an anti-slip pad is connected to the inner wall of the V-shaped clamping plate.

[0009] Furthermore, the upper end of the positioning block is inclined, and the two positioning blocks are symmetrically distributed between the left and right.

[0010] Furthermore, the clamping drive assembly includes a guide rod, an L-shaped push plate, a forward and reverse motor, a main gear, a bidirectional screw and a sub-gear.

DETAILED DESCRIPTION

[0020] Cylinder fixing tooling:

[0021] like Figure 1-3 As shown, in this embodiment, it includes a workbench 1 and two pressing plates 3, the two pressing plates 3 are symmetrically distributed on the left and right and are both arranged on the upper end of the workbench 1, a V-shaped clamp 2 is provided on the inner side of the pressing plate 3, a spring telescopic rod 8 is fixed to the inner end of the V-shaped clamp 2, a positioning block 9 is connected to the end of the spring telescopic rod 8, the upper end of the positioning block 9 is inclined, and the two positioning blocks 9 are symmetrically distributed on the left and right.

[0022] When the cylinder is fixed by the tooling, the cylinder is inserted from top to bottom between the two V-shaped clamps 2. During this process, the cylinder will slide downward along the inclined surface of the positioning block 9, and at the same time, the cylinder will push the positioning block 9 outward, and the positioning block 9 will compress the spring telescopic rod 8 until the cylinder is supported by the tooling table 1. At this time, the elasticity of the spring telescopic rod 8 can drive the positioning block 9 to quickly clamp the cylinder in place, without the need for manual support to clamp the cylinder, which reduces the trouble of operation and prevents the cylinder from being skewed or offset due to hand shaking.

[0023] like Figure 2 , 3 As shown, in this embodiment, a pressure sensing switch 5 and a spring return rod 6 are connected between the pressing plate 3 and the adjacent V-shaped clamping plate 2, a pressure indicator light 7 is fixed on the outside of the pressing plate 3, and a clamping drive assembly is provided outside the pressing plate 3, and the clamping drive assembly includes a guide rod 10, an L-shaped push plate 4, a forward and reverse motor 13, a main gear 14, a bidirectional screw rod 12 and a sub-gear 15. The guide rod 10 is provided with two and fixed one by one to the left and right ends of the tooling table 1, and the L-shaped push plate 4 is provided with two and sliding one by one. The forward and reverse motors 13 are fixed in the mounting cavity 11, and the main gear 14 is connected to the power end of the forward and reverse motors 13. The bidirectional screw rod 12 is arranged in the mounting cavity 11, and the sub-gear 15 is fixedly sleeved on the periphery of the bidirectional screw rod 12. The main gear 14 is meshed with the sub-gear 15. The left and right ends of the bidirectional screw rod 12 are rotated to pass through the outside of the workbench 1, and the L-shaped push plate 4 is threadedly sleeved with the bidirectional screw rod 12.

[0024] Then, the main gear 14, the sub-gear 15 and the bidirectional screw 12 are driven to rotate through the operation of the forward and reverse motor 13. The bidirectional screw 12 will drive the L-shaped push plate 4 to slide along the guide rod 10 and make the two L-shaped push plates 4 approach each other. Therefore, the L-shaped push plate 4 will drive the telescopic rod 19, the adjustment plate 18, the pressure plate 3, the pressure sensing switch 5, the spring return rod 6 and the V-shaped clamping plate 2 to approach the outer surface of the cylinder, which is conducive to quickly positioning and installing the cylinder through the V-shaped clamping plate 2. The V-shaped clamping plate 2 is conducive to clamping and fixing cylinders of various outer diameters, effectively ensuring the applicability of the tooling.

[0025] like Figure 2 As shown, in this embodiment, a pressure sensing switch 5 and a spring return rod 6 are connected between the pressing plate 3 and the adjacent V-shaped clamping plate 2, and a pressure indicator light 7 is fixed to the outer side of the pressing plate 3.

[0026] And under the premise that the pressure sensing switch 5 is set to be connected to the signal of the pressure indicator light 7, and the starting value of the pressure sensing switch 5 is set in advance to the force when the V-shaped clamp 2 just clamps the cylinder, so when the cylinder is completely clamped and fixed by the V-shaped clamp 2, when the V-shaped clamp 2 presses to start the pressure sensing switch 5, the pressure sensing switch 5 will control the pressure indicator light 7 to light up after reaching the starting value. By checking the lighting of the pressure indicator light 7, the staff can know in time that the cylinder is clamped and fixed, avoiding the situation where the clamping force is too large or too small, thereby facilitating the clamping and fixing of the cylinder with precise and appropriate force, and the operation is convenient.

[0027] like Figure 2 As shown, in this embodiment, an adjustment plate 18 fixed to the outside of the pressure plate 3 is provided above the L-shaped push plate 4, and a telescopic rod 19 is connected between the adjustment plate 18 and the adjacent L-shaped push plate 4. The upper end of the L-shaped push plate 4 is rotatably connected with a threaded adjustment rod 17, and the threaded adjustment rod 17 is threaded upward through the adjustment plate 18.

[0028] When it is necessary to adjust the clamping height of the V-shaped clamp 2 to the cylinder, the threaded adjusting rod 17 is turned to drive the adjusting plate 18, the pressure plate 3, the spring return rod 6, the pressure sensing switch 5 and the V-shaped clamp 2 to move up and down. During this process, the adjusting plate 18 will stretch or compress the telescopic rod 19, thereby smoothly adjusting the clamping height of the V-shaped clamp 2. This is conducive to clamping the cylinder of corresponding height through the V-shaped clamp 2, effectively ensuring the practicability of the fixed tooling.

[0029] like Figure 3 As shown, in this embodiment, the inner wall of the V-shaped clamping plate 2 is connected with an anti-slip pad 16.

[0030] By arranging the anti-skid pad 16 on the inner wall of the V-shaped clamping plate 2, the anti-skid pad 16 contacts the surface of the cylinder, which is beneficial to increase the friction after contact, thereby better ensuring the firmness of the V-shaped clamping plate 2 to clamp and fix the cylinder.
