[0036] The bottom of the outer frame 12 is provided with a positioning groove 15 for guiding and positioning with the main equipment; the top is provided with a slot 16, through which the hooking and conveying mechanism of the main equipment can hook and convey the clamp; a plug 17 is provided on one side of the slot 16. The plug 17 is a Harding quick plug 17, which includes a gas grid interface, floating installation design and self-guiding.

[0037] Example 2

[0038] Because changing the shape of large fixtures is difficult, relying on professional personnel to assemble them manually is time-consuming, labor-intensive, and unsafe; or, if the equipment is not changed, new equipment needs to be invested, which greatly increases costs. Therefore, based on Embodiment 1, this utility model proposes a large fixture changing device that can ensure that operators can safely, easily, and quickly complete the fixture changing when the equipment needs to change the shape of large fixtures.

[0039] like Figures 1-5 As shown, a large fixture changing device includes a frame 1, a base plate 2 is horizontally fixedly installed inside the frame 1, an electric cylinder parallel to the Z-axis is installed on the base plate 2, and the output end of the electric cylinder is connected to a support plate 3, which is located above the base plate 2.

[0040] The support plate 3 is provided with a frame 7 and a push hook mechanism 4 that can move horizontally along the X-axis. Guide plates 6 are fixedly installed on the inner walls of both sides of the frame 7. Rollers 5 are provided on the upper and lower sides of each guide plate 6, and the rollers 5 and the guide plates 6 are located on the left and right sides of the push hook mechanism 4.

[0041] Specifically, the base plate 2 divides the internal space of the frame 1 into two independent chambers. The support plate 3 and the frame 7 are both located in the upper chamber, and the two can be raised and lowered synchronously under the drive of the electric cylinder. Furthermore, under the drive of the push hook mechanism 4, the outer frame 12 and the clamps on its inner side can move back and forth inside and outside the frame 7.

[0042] The inner side of the front end of the guide plate 6 is provided with a chamfer, and the guide plate 6 is located on the outer side of the outer frame 12, and the guide plate 6 is used for limiting and guiding the clamp. The guide strip 14 of the outer frame 12 is overlapped on the roller 5. The roller 5 adopts a cam follower, and the clamp can be conveyed forward through rolling friction, thereby reducing the friction resistance. Two layers of rollers 5 can make the clamp compatible with a part of the height difference when the clamp is docked with the main equipment. The electric cylinder can also be replaced by an oil cylinder or an air cylinder according to the needs.

[0043] The push hook mechanism 4 is used for pushing and hooking the clamp. The push hook mechanism 4 includes a base 401, a push plate 402, and a check block 404. The base 401 can move along the X-axis direction. The push plate 402 is fixedly installed on the base 401 and is used for pushing the clamp. The check block 404 located on the front side of the push plate 402 is used for hooking and pulling back the clamp.

[0044] The front side of the push plate 402 is provided with a support 403. The check block 404 is rotationally connected with the support 403 through a rotation shaft parallel to the Y-axis direction. A torsional spring for driving the check block 404 to flip upward and reset is installed on the rotation shaft. The top surface of the check block 404 is a slope.

[0045] When the base 401 moves forward, the driving block 13 at the bottom of the outer frame 12 is in contact with the slope of the check block 404. With the forward movement of the base 401, extrusion occurs between the driving block 13 and the check block 404. The check block 404 is pressed and flips downward around the rotation shaft until the driving block 13 passes the check block 404, and the extrusion disappears. Under the action of the torsional spring, the check block 404 resets and hooks the outer frame 12 through the driving block 13. At this time, the push plate 402 is in contact with the rear end surface of the outer frame 12. Under the support of the roller 5 and the drive of the push plate 402, the outer frame 12 can carry the large clamp to move forward along the X-axis to the installation position of the equipment. Then, the support plate 3 moves downward, so that the highest part of the check block 404 passes the bottom of the driving block 13, and the unlocking is completed.

[0046] Similarly, when the check block 404 hooks the driving block 13 and the base 401 moves backward, the outer frame 12 can be moved to the inside of the frame body 7, thereby assisting the workers to remove the large clamp.

[0047] The support plate 3 is fixedly installed with two slide rails 301 parallel to the X-axis direction. The base 401 is slidingly installed on the two slide rails 301. One side of the slide rail 301 is rotationally installed with a lead screw 302. A connecting plate 303 is rotatably installed on the lead screw 302. One end of the connecting plate 303 is fixedly connected with the base 401.

[0048] The rear end of the lead screw 302 is fixedly connected with a handle wheel 304. The operator only needs to shake the handle to easily pull back and push out the clamp. The rear end of the lead screw 302 can also be connected with a motor. The motor drives the lead screw 302 to rotate, and then drives the base 401 to move along the slide rail 301 through the connecting plate 303.

[0049] The limiting plate 305 capable of abutting against the base 401 is fixedly installed on the side of the support plate 3 close to the handle wheel 304, and the buffer assembly 9 for positioning is installed on the front end of the support plate 3 close to the lead screw 302. The buffer assembly 9 adopts the prior art, and the limiting and buffering are combined, so that the operator only needs to send the clamp to the limiting position through the handle when pushing out; and the limiting plate 305 is used for blocking the base 401 to avoid excessive rear movement of the base 401.

[0050] In order to guarantee the stability of the support plate 3 during lifting, the guide rod 10 parallel to the Z-axis direction is slidably arranged on the bottom plate 2, and the upper end of the guide rod 10 is fixedly connected with the bottom plate 2; and the guide rod 10 is externally sleeved with the sleeve 11, the sleeve 11 is fixedly arranged on the bottom plate 2, and the linear bearing is arranged between the guide rod 10 and the sleeve 11. Through the sleeve 11 and the linear bearing, the friction and wear between the guide rod 10 and the bottom plate 2 can be reduced, and the position accuracy of lifting can also be improved.

[0051] As described above, the foot wheels are installed on the bottom of the rack 1, which facilitates the operator to move the rack 1; the precisely processed positioning plate is installed on the front side of the rack 1, which is used for left-right positioning of the rack 1, and facilitates the operator to push the rack 1 into the groove of the main equipment for replacing the clamp.

[0052] The front end of the support plate 3 is also provided with the locking plate 8, when the operator pushes the rack 1 to the position, the sensor of the main equipment detects the locking plate 8, and automatically extends the latch to lock the locking plate 8, so that the rack 1 cannot be accidentally shaken during replacement of the clamp.

[0053] Working principle:

[0054] Firstly, the rack 1 is moved to the groove of the main equipment for replacing the clamp through the foot wheels and the positioning plate, and then the latch locks the locking plate 8, and then the replacement of the clamp is carried out.

[0055] When the clamp is removed, the handle wheel 304 drives the lead screw 302 to rotate, so that the base 401 moves forward, the driving block 13 at the bottom of the outer frame 12 is in contact with the inclined surface of the check block 404, and the extrusion between the driving block 13 and the check block 404 occurs with the forward movement of the base 401, the check block 404 is pressed and rotates downward around the rotating shaft, until the driving block 13 passes the check block 404, the extrusion disappears, and under the action of the torsional spring, the check block 404 is reset and hooks the outer frame 12 through the driving block 13; then the handle wheel 304 is reversely shaken, so that the base 401 moves backward along the slide rail 301, until the base 401 is in contact with the limiting plate 305.

[0056] When the mounting clamp is installed, the handle wheel 304 is rotated to drive the base 401 to move forward, the push plate 402 is in contact with the rear end surface of the outer frame 12, and under the support of the roller 5 and the drive of the push plate 402, the outer frame 12 can carry the large clamp to move forward along the X axis to the installation position of the equipment, at this time, the base 401 is located at the buffer assembly 9; then the support plate 3 is lowered, so that the highest part of the check block 404 is higher than the bottom of the drive block 13, thereby completing the unlocking, and the base 401 can move backward to the limiting plate 305.

[0057] In conclusion, the large clamp changing device can help personnel to easily push the clamp to the predetermined position by the labor-saving structure of the lead screw 302, the hook pulling clamp assembly of the push hook mechanism 4 is designed by using the check mechanism, the clamp can be automatically hooked and unlocked, the height of the outer frame 12 can be adjusted by the lifting of the support plate 3 to adapt to different equipment heights, the rack 1 is automatically positioned after being positioned, the main equipment is completely closed to ensure the safety of personnel, and the special clamp outer frame 12 design ensures the positioning accuracy of the clamp.

[0058] Therefore, the device has the following advantages: good safety, meeting the CE requirements of European customers; simple operation and high efficiency, only simple handle shaking is needed to receive and send the clamp, and professional manual loading and debugging are not needed; good accuracy, low personnel participation rate and good consistency; good compatibility, equipped with the air-electricity network quick plug 17, and compatible with any complex clamp.
