[0046] In order to facilitate understanding by those skilled in the art, the present invention will be further described below with reference to the accompanying drawings.

[0047] Please refer to Figures 1-4 , which is an embodiment of a tooling for machining porous workpieces of shafts, a key component of a reciprocating compressor, provided by the present invention, comprising a base 1, a rolling support assembly 2, a clamping assembly, and a fixed support assembly 4; wherein, the base 1 provides space for installation and support, and the rolling support assembly 2, the clamping assembly, and the fixed support assembly 4 are all mounted on the base 1. The workpiece 8 has a flange end 801 and a long axis end 802. The workpiece 8 is placed on the rolling support assembly 2 and the fixed support assembly 4. The rolling support assembly 2 supports the flange end 801, and the fixed support assembly 4 supports the long axis end 802. The clamping assembly comprises a gasket 7 and a clamping structure 3, which cooperate to clamp and tighten the flange end 801 of the workpiece 8, thereby achieving axial limitation of the workpiece 8.

[0048] The base 1 includes a bottom plate 101 and a vertical plate 105. The bottom plate 101 can be fixedly connected to the workbench of the equipment using bolts; the vertical plate 105 is fixedly installed on the bottom plate 101; an avoidance channel 108 is provided on the vertical plate 105 for installation and removal of the workpiece 8; the avoidance channel 108 can be circular, and preferably the avoidance channel 108 is a U-shaped shape with an upper opening, which is convenient for loading and unloading the workpiece 8, and can also take into account the processing of radial holes on the workpiece 8, providing sufficient operating space. When the upper part of the avoidance channel 108 is open, the vertical plate 105 has two support arms, and the two support arms are located on both sides of the avoidance channel 108. The vertical plate 105 can be an integral structure; or the two support arms can be processed separately, independently set and respectively fixed on the bottom plate 101. The vertical plate 105 and the bottom plate 101 can be an integral structure, or they can be fixedly connected by welding or other methods.

[0049] A rib 106 can be positioned between the base plate 101 and the uprights 105. Ribs 106 connect the two and support them. The ribs 106, base plate 101, and uprights 105 form a triangular structure, enhancing the rigidity of the base 1. Ribs 106 can be welded to the base plate 101 to ensure stability and minimize vibration during machining of the workpiece 8. Ribs 106 are provided with various weight-reducing grooves to reduce the overall weight of the tooling.

[0050] The rolling support assembly 2 includes two driving wheels 202, which are located on both sides of the avoidance channel 108 and jointly support the flange end 801 of the workpiece 8. Preferably, the driving wheels 202 are slidably set on the base plate 101 through a movable bracket 204, and the two driving wheels 202 can be slidably moved closer or separated, thereby adapting to the support requirements of workpieces 8 with different outer diameters. Specifically, a first guide rail 103 and a second guide rail 104 are provided on the base plate 101, and the first guide rail 103 and the second guide rail 104 are parallel to each other, and the movable bracket 204 is slidably set on the first guide rail 103 and the second guide rail 104. For example, the first guide rail 103 and the second guide rail 104 are T-slots, and the movable bracket 204 is connected to the base plate 101 using T-bolts extending into the T-slots. The head of the T-bolt slides in the T-slot, while the threaded portion passes through the movable bracket 204 and connects to the nut. When the nut and T-bolt are loosely fitted, the movable bracket 204 can be moved and adjusted relative to the base plate 101. When the nut and T-bolt are tightly fitted, the relative position of the movable bracket 204 and the base plate 101 is locked. Of course, the sliding connection between the movable bracket 204 and the base plate 101 can also adopt other existing structures. For example, the first guide rail 103 and the second guide rail 104 are dovetail guide rails, and the movable bracket 204 is slidingly arranged on the dovetail guide rails and locked with bolts. This is a conventional structure.

[0051] Furthermore, an adjustment element 203 is provided between the two mobile supports 204. This adjustment element 203 can be a bidirectional screw, with two threaded portions of the screw threadedly connected to the two mobile supports 204. After unlocking the mobile supports 204, the adjustment element 203 is rotated, causing the two mobile supports 204 to move closer or further apart, thereby driving the two driving wheels 202 closer or further apart. The adjustment element 203 can also be an electric telescopic rod, a pneumatic cylinder, a hydraulic cylinder, or other retractable element, as long as it can controllably adjust the distance between the two mobile supports 204.

[0052] The driving wheel 202 is rotatably mounted on a mobile bracket 204, on which a driving element 201 is mounted. The driving element 201 may be a servo motor, which is connected to the driving wheel 202 through a reducer and other components. The driving element 201 is controlled to drive the driving wheel 202 to rotate, thereby rotating the workpiece 8 located on its upper side, so that different positions of the workpiece 8 correspond to the processing tools to complete the processing.

[0053] The clamping assembly is mounted on the vertical plate 105 and distributed circumferentially around the avoidance channel 108, and can be located on both support arms of the vertical plate 105. The clamping assembly includes a plurality of pads 7 and a plurality of clamping structures 3. The pads 7 and clamping structures 3 are positioned on either side of the flange end 801 of the workpiece 8, respectively, to clamp and secure the flange end 801 of the workpiece 8. The number of pads 7 and clamping structures 3 can be set as needed. Preferably, there is a one-to-one correspondence between pads 7 and clamping structures 3, i.e., one pad 7 corresponds to one clamping structure 3, applying a clamping force at corresponding locations on either side of the flange of the workpiece 8, providing good stability.

[0054] The pad 7 is fixed on the vertical plate 105, and the side of the pad 7 facing away from the vertical plate 105 is the supporting surface. The supporting surfaces of several pads 7 are in the same plane, and they jointly support the workpiece 8. The pad 7 and the vertical plate 105 can be an integral structure, with the pad 7 protruding from the surface of the vertical plate 105; the pad 7 can also be detachably connected to the vertical plate 105, for example, by bolts, screws and other connecting parts. The shape of the pad 7 is not limited to Figure 2 The cylindrical shape shown can also be a rectangular table, an arc table, etc.

[0055] Please refer to Figure 5 The clamping structure 3 includes a pressure plate 303, which is mounted on the vertical plate 105 via a connecting assembly. The connecting assembly allows the pressure plate 303 to partially clamp the workpiece 8 when clamping it. During loading and unloading, the pressure plate 303 avoids the loading and unloading space of the workpiece 8. For example, the connecting assembly includes a first support rod 304. The pressure plate 303 is provided with a first adjustment hole 306, which extends through the pressure plate 303 and is positioned within the first adjustment hole 306. One end of the first support rod 304 is connected to the vertical plate 105, and the other end is threadedly connected to the first locking member 305. The first adjustment hole 306 can be a circular hole. When loading and unloading the workpiece 8, the pressure plate 303 can be rotated relative to the first support rod 304 to avoid the loading and unloading area of ​​the workpiece 8. When clamping the workpiece 8, one side of the workpiece 8 rests on the pad 7, and the pressure plate 303 is rotated so that it partially presses on the other side of the workpiece 8. Then, the first locking member 305 is tightened to achieve stable clamping of the workpiece 8. The first adjustment hole 306 can also be an elongated hole extending in the length direction of the pressure plate 303. By moving the pressure plate 303 along the length direction of the first adjustment hole 306, the pressure plate 303 can be moved away from the loading and unloading area of ​​the workpiece 8 or partially press on the workpiece 8.

[0056] Furthermore, the position of the pressing plate 303 relative to the vertical plate 105 can be adjusted, thereby ensuring that the pressing plate 303 is clamped at a portion of the workpiece 8 that does not require processing. Specifically, a sliding track 107 is provided on the vertical plate 105, and the first support rod 304 is slidably arranged on the sliding track 107. For example, the sliding track 107 is a T-slot, and a first connecting block 301 is fixed to one end of the first support rod 304 connected to the vertical plate 105. The first connecting block 301 is T-shaped and slides within the sliding track 107; a second locking member 302 is threadedly connected to the first support rod 304, and the second locking member 302 is located on the outside of the sliding track 107. After the position of the pressing plate 303 is adjusted, the second locking member 302 can be used to fix the position of the pressing plate 303 on the vertical plate 105. The sliding track 107 can also use a dovetail guide rail protruding from the vertical plate 105, and the first connecting block 301 needs to be provided with a dovetail groove accordingly to achieve a sliding connection between the two; at this time, the sliding track 107 and the first connecting block 301 can be locked in position by tightening screws. This sliding connection method between the sliding track 107 and the first connecting block 301 is an existing technology, so it is not shown in the drawings and will not be explained in detail here.

[0057] The sliding track 107 surrounds the avoidance channel 108 and is preferably arc-shaped; this allows the pressing plates 303 to be evenly distributed in the circumferential direction of the workpiece 8 , resulting in good clamping force stability.

[0058] Please refer to Figure 6 An auxiliary adjustment track 109 is also provided on the outside of the sliding track 107, on which an auxiliary support rod 307 is slidably mounted. When the pressure plate 303 is locked, the auxiliary support rod 307 and the pad 7 are located on either side of the sliding track 107, further improving the stability of the clamping of the pressure plate 303. The auxiliary adjustment track 109 can be a guide rail protruding from the vertical plate 105 or a groove formed by a partial inward concave portion of the vertical plate 105, depending on the actual assembly requirements.

[0059] The fixed support assembly 4 includes two driven wheels 402 . The two driven wheels 402 are respectively located on both sides of the avoidance channel 108 . The driven wheels 402 are rotatably mounted on the base plate 101 through a fixed bracket 401 .

[0060] Furthermore, an adapter bracket 403 is provided between the fixing bracket 401 and the bottom plate 101, such as Figure 7 and Figure 8As shown, a second adjustment hole 404 is provided on the adapter bracket 403, and the fixed bracket 401 is connected to the adapter bracket 403 by a bolt located in the second adjustment hole 404; since the second adjustment hole 404 is a long hole and extends in the direction of the connection line of the two driven wheels 402, that is, extends along the X-axis direction of the three-coordinate axis, the position of the fixed bracket 401 can be adjusted to increase or decrease the distance between the two driven wheels 402, thereby meeting the support requirements of workpieces 8 with different outer diameters; it plays a role in supporting the center of gravity of the workpiece 8 and rotating the workpiece 8 to reduce friction and prevent the workpiece 8 from rotating and deflecting.

[0061] The bottom plate 101 is also provided with an end clamping assembly 6, such as Figure 9 As shown, the end clamping assembly 6 includes a first support column 603 , the lower end of the first support column 603 is connected to the base plate 101 , and the upper end is provided with an end pressure plate 604 , which is used to assist in clamping the workpiece 8 .

[0062] Preferably, the upper end of the first support column 603 is provided with an external thread, and the end pressure plate 604 is sleeved on the external thread of the first support column 603 and fixed in position by a third locking member 605 located on the upper side of the end pressure plate 604 and a fourth locking member 608 located on the lower side of the end pressure plate 604; wherein the third locking member 605 and the fourth locking member 608 are both threadedly connected to the first support column 603. The third locking member 605 and the fourth locking member 608 can be nuts.

[0063] Furthermore, the first support column 603 is slidably mounted on the base plate 101. Specifically, the base plate 101 is provided with a third guide rail 110, which is a T-slot. A slider 601 is fixed to the lower end of the first support column 603 and slides within the T-slot. Furthermore, to lock the position of the first support column 603, the lower end of the first support column 603 is provided with an external thread, which is screwed onto a fifth locking member 602. Adjustment or position locking of the first support column 603 is achieved by loosening or tightening the fifth locking member 602.

[0064] The end clamping assembly 6 also includes a second support column 606, the upper end of which is connected to the end pressure plate 604, and the lower end is resting on the base plate 101 through a pad 607 or is slidably connected to the third guide rail 110; the second support column 606 is located on the side of the first support column 603 away from the workpiece 8, which can improve the clamping stability of the end pressure plate 604 and prevent the workpiece 8 from moving.

[0065] An automatic probe 5 is mounted on the vertical plate 105 to detect the position of the workpiece 8. Preferably, the automatic probe 5 is located on the inner side of the slide track 107, near the side of the avoidance channel 108. This allows the automatic probe 5 to detect parts of all sizes. Depending on the structure of the workpiece 8, the automatic probe 5 can employ appropriate detection elements. For example, the automatic probe 5 can be a laser detection device with a built-in proximity switch sensor and a laser-reflecting infrared device. This allows the position of the blank's features to be aligned as the workpiece 8 rotates, eliminating the need for manual measurement and alignment using a dial gauge or height gauge.

[0066] When using this tool,

[0067] The workpiece 8 is hoisted and placed on the rolling support assembly 2 and the fixed support assembly 4, with the flange end 801 located on the rolling support assembly 2 and the long axis end 802 located on the fixed support assembly 4;

[0068] Place the flange end 801 of the workpiece 8 against the pad 7, adjust the driving wheel 202 to rotate the workpiece 8 to the laser calibration position of the automatic probe 5, then stop rotating, adjust the position of the pressure plate 303 and press the flange end 801 of the workpiece 8, and after the end clamping assembly 6 presses the long axis end 802 of the workpiece 8, you can start processing. During the processing process, if you need to change the processing position, first release the clamping of the pressure plate 303 and the end clamping assembly 6, then control the driving wheel 202 to rotate the workpiece 8 to the next processing position; after reaching the position, adjust the pressure plate 303 to press the flange end 801 of the workpiece 8, and after the end clamping assembly 6 presses the long axis end 802 of the workpiece 8, you can start processing the next position.

[0069] When replacing a different outer cylindrical workpiece 8, the upper and lower heights of the workpiece 8 can be controlled by controlling the adjustment element 203 to synchronously adjust the distance between the two driving wheels 202; controlling the driving wheel 202 to rotate drives the workpiece 8 to rotate to the correct position, replacing manual rotation.

[0070] Furthermore, several fourth guide rails 102 are provided on the base plate 101 to reserve installation positions for expanding the clamping function of the tooling. For example, the fourth guide rail 102 is located on the base plate 101 near the driving wheel 202, and is used to apply a tightening clamping force on the end face of the flange end 801 of the workpiece 8 through a rod or other structure located in the fourth guide rail 102 when the end face of the flange end 801 of the workpiece 8 needs to be positioned or clamped.

[0071] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
