Description

[0002] The refrigeration compressor is the core component of the refrigeration cycle. It compresses the refrigerant gas to increase its pressure and temperature in order to achieve the transfer of heat energy. The refrigeration compressor is composed of multiple key components. Different types of compressors (such as piston, screw, scroll, centrifugal, etc.) have different specific components.

[0003] When processing compressors, clamping equipment is often used to assist in processing or assembling the compressors. However, the compressors have a complex structure and many parts, among which sensors, shaft seals, seals, crankshafts, connecting rods, etc. are all fragile parts, and secondly, they are of different shapes. The existing clamping equipment generally relies on friction or extrusion stress between the workpiece and the workpiece to achieve clamping and fixing, but this method can only be used for hard parts with low appearance requirements. Once the workpiece is relatively fragile and has high appearance requirements, the existing clamping equipment is easy to cause damage to the workpiece. Secondly, most of them can only clamp cylindrical or rectangular workpieces, and the clamping range is limited.

[0028] For details, see Figure 3 and Figure 6 As shown, a plurality of telescopic grooves 11 are evenly provided in the clamping arm 9 along a direction perpendicular to the movable plate 6, a hydraulic telescopic rod 17 is provided in the telescopic groove 11, a push rod 18 is rotatably connected to the top of the hydraulic telescopic rod 17, and a rubber ball 19 is provided at the top of the push rod 18; a receiving groove 14 is provided just above the telescopic groove 11, a ring-shaped airbag 23 is slidably connected in the receiving groove 14, avoidance grooves 16 are provided through the upper and lower ends of the receiving groove 14, and slide grooves 15 are symmetrically provided on the telescopic groove 11 at the upper and lower ends of the receiving groove 14, and the slide grooves 15 are provided on the telescopic groove 11. 5 is slidably connected to the limiting assembly 22, and the annular airbag 23 is arranged on the limiting assembly 22. The top rod 18 is provided with a slot 20 adapted to the limiting assembly 22 to drive the limiting assembly 22 to slide along the slide groove 15; the second mounting plate 7 is provided with an air pump 26 for inflating and sucking the annular airbags 23, and the connecting pipe between the air pump 26 and the annular airbag 23 is made of a hose material. It should be noted here that the detailed connection method between the air pump 26 and the annular airbag 23 is not shown in the figure, but only in the figure. Figure 2 The air pump 26 is used to inflate and inhale the annular airbag 23.

[0029] Among them, see Fig. 9As shown, the limiting assembly 22 includes a guide block 224 slidably connected in the slide groove 15, the guide block 224 is fixedly connected to the limiting cylinder 221, the limiting cylinder 221 is slidably connected to the limiting rod 222, and a spring 223 is arranged in the limiting cylinder 221, one end of the spring 223 is fixedly connected to the limiting cylinder 221, and the other end is fixedly connected to the inner wall of the top end of the limiting cylinder 221, the bottom end of the limiting rod 222 extends into the telescopic groove 11 to form a wedge-shaped structure, and is adapted to the card slot 20, and the top end of the limiting rod 222 extends to the outside of the avoidance groove 16, so that when the hydraulic telescopic rod 17 drives the push rod 18 to slide and retract along the telescopic groove 11, the push rod 1 The card slot 20 on 8 will clamp the wedge-shaped structure at the bottom end of the limit rod 222, thereby driving the limit rod 222 and the limit cylinder 221 to slide along the avoidance groove 16, and then driving the guide block 224 to slide in the slide groove 15. The guide block 224 and the slide groove 15 are provided to control the stability of the limit rod 222 and the limit cylinder 221 sliding in the avoidance groove 16 to prevent them from moving up and down; by fixing the annular airbag 23 to the limit cylinder 221, the annular airbag 23 can be driven to extend out of the accommodating groove 14, and then inflated by the air pump 26, and the opposite annular airbag 23 works together to achieve a tight clamping of the fragile workpiece.

[0030] Further, by Figure 3 , Figure 6 and Figure 7As shown, a limit block 21 is fixedly arranged on the push rod 18, a first limit groove 12 adapted to the limit block 21 is provided on one side of the telescopic slot 11, and a second limit groove 13 adapted to the limit block 21 is provided on the bottom side of the telescopic slot 11, the angle between the first limit groove 12 and the second limit groove 13 is 90 degrees, and the second limit groove 13 is an L-shaped structure, one end of which is perpendicular to the axial direction of the telescopic slot 11 is connected to the first limit groove 12, and the position of the end of the L-shaped structure of the second limit groove 13 which is perpendicular to the axial direction of the telescopic slot 11 is adapted to the end position of the guide block 224 sliding to the slide groove 15 in the clamping arm 9, so that when only the push rod 18 and the rubber ball 19 are working, it is temporarily set (taking the limit block 21 and the first limit groove 12 in the figure as an example) that the limit block 21 is stuck in the second limit groove 12 as the initial state, that is, when the hydraulic telescopic rod 17 drives the push rod When 18 is extended or retracted, the annular airbag 23 does not need to be involved. The push rod 18 is rotated (there is a specially matched sleeve, which is inserted into the telescopic groove 11, and then there is an avoidance opening on the sleeve, which is adapted to the limit block 21. The rotating sleeve can drive the push rod 18 to rotate, which is not specifically drawn in the figure), so that the limit block 21 rotates to the second limit groove 13 through the horizontal end of the second limit groove 13 of the L-shaped structure (the end perpendicular to the axial direction of the telescopic groove 11). In this way, when the push rod 18 is extended or retracted, the slot 20 on the push rod 18 will not be stuck in the wedge-shaped structure at the bottom end of the limit rod 222, so that only the push rod 18 is extended or retracted. On the contrary, when the limit block 21 is in the first limit groove 12, the slot 20 on the push rod 18 will be engaged with the limit rod 222, thereby driving the limit rod 222 to slide in the avoidance groove 16, thereby driving the annular airbag 23 to move out of the work.

[0031] It is worth mentioning that see Figure 3 and Figure 4 As shown, an anti-skid pad 24 is fixedly provided on the opposite side of the two clamping arms 9, and an opening compatible with the telescopic slot 11, the first limit slot 12, the second limit slot 13, the slide slot 15 and the avoidance slot 16 is opened on the anti-skid pad 24, so that it is convenient for the push rod 18, the rubber ball 19 and the annular airbag 23 to extend out of their respective slots and then clamp the workpiece, and a number of anti-skid grooves 25 are also opened on the anti-skid pad 24 to increase the friction between the workpiece and the anti-skid pad 24. The reason for setting the anti-skid pad 24 is that when clamping ordinary workpieces with high hardness and low appearance requirements, it is necessary to use the push rod 18, rubber ball 19 or annular airbag 23 for flexible clamping. The above-mentioned drive motor 81 drives the two clamping arms 9 to move toward each other for clamping. At this time, it is necessary to increase a certain amount of friction and simple protection, and the anti-skid pad 24 can meet the daily clamping needs.

[0032] In addition, by Figure 7It can be seen that the annular airbag 23 is adapted to the receiving groove 14 in the fully inflated state, and the outer edge of the annular airbag 23 is larger than the outer edge of the rubber ball 19. This arrangement is for when the annular airbag 23 is needed to work, after the annular airbag 23 is filled with air, when the two opposite annular airbags 23 are pressed tightly to clamp the fragile workpiece, the rubber ball 19 cannot participate in the work, because its texture is rubber material, which is still harder than the annular airbag 23. Therefore, after the annular airbag 23 is fully inflated, it needs to be larger than the outer edge of the rubber ball 19, so that after the annular airbag 23 is squeezed in the fully inflated state, it can still ensure that the rubber ball 19 does not participate in the clamping. holding work; secondly, it should be added that, if the workpiece is not too fragile, the inflation degree of the annular airbag 23 can be adjusted, so that the rubber ball 19 and the annular airbag 23 can participate in the clamping work together, so that the material range of the clamped workpiece can be further increased; so if it is a very ordinary workpiece, the anti-slip pad 24 is directly used for contact clamping. If it is generally fragile and needs to protect the appearance, the rubber ball 19 is needed to participate in the work. For relatively fragile workpieces, only the annular airbag 23 is allowed to participate in the clamping work. For the rest, the inflation degree of the annular airbag 23 can be adjusted according to the specific situation to adapt it to the material of the workpiece.

[0033] It should also be added that the reason for using several groups of push rods 18, rubber balls 19 and corresponding annular air bags 23 is to enable the entire clamping system to adapt to the clamping of most workpieces, so that it is not only limited to rectangles and cylinders. Because each hydraulic telescopic rod 17 works independently, the workpiece can be clamped from all directions by several rubber balls 19 or annular air bags 23, and the material of the rubber balls 19 and the annular air bags 23 can further increase the clamping area with the workpiece, making it flexible to adapt to the clamping of most workpieces.

[0034] This effectively solves the problems that the existing clamping equipment is prone to damage fragile workpieces when clamping workpieces, and most of them can only clamp rectangular and circular workpieces.

[0035] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the present invention and are not intended to limit the present invention.
