[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-4This utility model provides a technical solution: a mechanical XYZ compensation module, including a housing 1. The housing 1 is internally provided with an X / Y arbitrary position storage mechanism 2, an X / Y center locking mechanism 3, and a Z-axis locking mechanism 6. The 2 includes a storage block 201, a first sealing ring 202, a second sealing ring 203, and a plunger 204. The 3 includes a positioning sleeve 301, a centering pin 302, a third sealing ring 303, a fourth sealing ring 304, a sixth sealing ring 305, a piston 306, and a magnetic ring 307. The 6 includes a limit block 601, a piston shaft 602, and a seventh sealing ring 603. The side of the housing 1 is provided with an X / Y center stabilization monitoring mechanism 4 and a Z-axis monitoring mechanism 5. The 4 includes a first sensor 401, a second sensor 402, a first mounting block 403, and a second mounting block 404. The 5 includes a third sensor 501, a third mounting block 502, a bolt 503, and a fourth mounting block 504. A robot mounting flange 7 is installed on the top of the housing 1.

[0022] Furthermore, housing 1 includes housing one 101, housing two 102 and housing three 103. A slider one 104 is installed on the top of housing one 101. A positioning sleeve 301 is installed in the positioning hole of housing one 101. A slide rail one 105 is movably fitted inside the slider one 104. X-axis compensation is performed by the movement between the slide rail one 105 and the slider one 104. The X-axis compensation range is ±10mm. A step is provided on housing one 101 and a limiting groove is provided on housing two 102 to limit the X-axis compensation.

[0023] Furthermore, a slide rail 106 is installed on the top of housing 2 102, and a slider 107 is movably fitted inside the slide rail 2 106. The bottom of housing 3 103 is connected to slider 2 107. A sealing ring 5 111 is placed in the hole at the top of housing 3 103. A pin 108 is installed at the bottom of housing 3 103. Linear bearing 113 and linear bearing 2 114 are provided at the top of housing 3 103. Snap ring 109 and snap ring 4 115 are connected between housing 3 103 and linear bearing 113. Snap ring 2 110 and snap ring 5 116 are connected between linear bearing 2 114 and 103. Snap ring 3 112 is connected between piston shaft 602 and housing 3 103. Y-axis compensation is achieved through the movement between slide rail 2 106 and slider 2 107. The Y-axis compensation range is ±10mm. The four pins 108 installed at the lower end of housing 3 103 limit the Y-axis compensation.

[0024] Furthermore, a connector 11 is installed on the side of the housing 103. Air is introduced through the connector 11 to make the lower end of the storage block 201 contact the upper end of the step set on the housing 101. The friction between the two achieves pneumatic locking at any eccentric position. When the air is cut off by the connector 11, the elastic force inside the four plungers 204 separates the lower end of the storage block 201 from the upper end of the housing 101.

[0025] Furthermore, connectors 1 and 2 9 are installed on the side of housing 3 103 away from connector 4 11. Sensor 1 401 and sensor 2 402 are installed in the holes of housing 3 103 near connector 4 11. Sensor 1 401 is fixed by mounting block 1 403, and sensor 2 402 is fixed by mounting block 2 404. Connector 2 9 is vented, causing piston 306 and centering pin 302 to move downwards, and centering pin 302 to be positioned with positioning sleeve 301. The connection is made via slide rail 1 105 and slider 1 104, and slide rail 2 106. The movement between the slider 107 and the housing 101 and housing 2 102 achieves center locking in the X / Y direction. The sensor 2 402 senses the magnetic ring 307 to monitor whether the piston 306 is in position, thereby confirming whether the center lock has been achieved. The connector 8 allows air to flow, causing the piston 306 and the centering pin 302 to move upward, disengaging the centering pin 302 from the positioning sleeve 301, thereby unlocking the X / Y lock of the housing 101 and housing 2 102. The sensor 401 senses the magnetic ring 307 to monitor whether the piston 306 is in position, thereby confirming whether the center lock has been unlocked.

[0026] Furthermore, springs 117 are installed inside housing 101, housing 2 102, and housing 3 103. The top of spring 117 is connected to the bottom of robot mounting flange 7. Guide shaft 118 and guide shaft 2 119 are installed in the bottom hole of robot mounting flange 7. A positioning bolt is connected between spring 7 and housing 3 103. Spring 117 enables housing 101, housing 2 102, and housing 3 103 to perform Z-axis compensation, with the Z-axis compensation range being 14mm.

[0027] Furthermore, a connector 3 10 is installed on one side of the robot mounting flange 7, a mounting block 3 502 is installed on the side of the housing 3 103 away from the connector 3 10, a sensor 3 501 is installed on the mounting block 3 502, a mounting block 4 504 is installed on the side of the robot mounting flange 7 away from the connector 3 10, and a bolt 503 is installed at the bottom of the mounting block 3 502. When the sensor 3 501 senses the bolt 503, it determines that the Z-axis compensation has reached its maximum value. The connector 3 10 is vented, so that a force is generated between the robot mounting flange 7 and the piston shaft 602, thereby ensuring that the two are always in the end position.

[0028] Working Principle: A mechanical XYZ compensation module mainly consists of a housing 1, an X / Y arbitrary position storage mechanism 2, an X / Y center locking mechanism 3, an X / Y center locking monitoring mechanism 3, a Z-axis monitoring mechanism 5, a Z-axis locking mechanism 6, and a robot mounting flange 7. The housing 1 is made of 7075 high-strength aluminum alloy, primarily for weight reduction in the mechanical XYZ compensation module. The X / Y arbitrary position storage mechanism 2 achieves pneumatic locking at any eccentric position through friction connection. The X / Y center locking mechanism 3 achieves center locking at the eccentric position through conformal positioning. The X / Y center locking monitoring mechanism 3 monitors the opening and closing of the center lock. The Z-axis locking mechanism 6 uses pneumatic drive to lock the Z-axis compensation at the terminal position, thus stopping Z-axis compensation operation. The Z-axis monitoring mechanism 5 monitors whether the Z-axis compensation is locked at the terminal position. The robot mounting flange 7 adopts a standardized ISO9409 robot interface design, meeting standardization requirements.

Slide rail 206 is installed on the upper end face of housing 202, and slide rail 105 is installed on the lower end face of housing 206. X-axis compensation is achieved through the movement between slide rail 105 and slider 104, with an X-axis compensation range of ±10mm. A step is provided on housing 101, and a limiting groove is provided on housing 202 to limit the X-axis compensation. Sealing ring 202 is installed in the inner hole of storage block 201, and sealing ring 203 is installed on the outer diameter of storage block 201. Four plungers 204 are installed on the screws of storage block 201. In the perforated hole, the storage block 201, which has been installed as described above, is fitted into the cylinder at the lower end of the housing 3 103; the sealing ring 303 is fitted into the outer groove of the centering pin 302, and the sealing ring 4 304 is placed in the upper groove of the centering pin 302; the sealing ring 6 305 is fitted into the outer groove of the piston 306, and the magnetic ring 307 is fitted into the outer groove of the piston 306; in summary, the lower end of the piston 306 is connected to the upper end of the centering pin 302, and the piston 306 and the centering pin 302, which have been installed as described above, are fitted into the cylinder of the housing 3 103 from the upper end; the sealing ring 5 111 is placed into the hole at the upper end of the housing 3 103; the limiting block 601 is installed on the lower end face of the piston shaft 602, and the piston shaft 602 is connected to the housing 3 103 through the snap ring 3 112; the outer groove of the piston shaft 602 is fitted with the sealing ring 7 603;

[0030] Four pins 108 are installed into the holes on the lower end face of housing 3 103. Two linear bearings 113 are connected to housing 3 103 from the top and bottom ends via snap rings 109 and 115. Two linear bearings 214 are connected to housing 3 103 from the top and bottom ends via snap rings 110 and 116. Slider 2 107 is fitted onto slide rail 2 106. The lower end face of housing 3 103 is then connected to the upper end face of slider 2 107. Y-axis compensation is achieved through the movement between slide rail 2 106 and slider 2 107. The Y-axis compensation range is ±10mm. The four pins 108 installed on the lower end of housing 3 103 limit the Y-axis compensation.

[0031] Install connector 411 onto the left side of housing 3103. Air is introduced through connector 411 to make the lower end of storage block 201 contact the upper end of the step set on housing 101. The friction between the two achieves pneumatic locking at any eccentric position. When the air is cut off by connector 411, the elastic force inside the four plungers 204 separates the lower end of storage block 201 from the upper end of housing 101.

Fix sensor 1 (401) with mounting block 1 (403) and sensor 2 (402) with mounting block 2 (404). Connector 2 (9) allows air to pass through, causing piston 306 and centering pin 302 to move downwards and positioning pin 302 with positioning sleeve 301. The movement between slide rail 1 (105) and slider 1 (104), and between slide rail 2 (106) and slider 2 (107) achieves center locking of housing 1 (101) and housing 2 (102) in the X / Y direction. Sensor 2 (402) senses magnetic ring 307 to monitor whether piston 306 is in position, thus confirming whether center locking has been achieved.

[0033] Vent 8 allows the piston 306 and centering pin 302 to move upwards, disengaging the centering pin 302 from the positioning sleeve 301, thereby unlocking the X / Y locks of housing 101 and housing 202. Sensor 401 senses the magnetic ring 307 to monitor whether the piston 306 is in position, thus confirming whether the center lock has been unlocked. The upper faces of the two guide shafts 118 and 119 are respectively installed into the lower holes of the robot mounting flange 7. Six springs 117 are placed on the upper face of housing 303.
