Description

Technical Field

However, when the die-casting is placed between the two clamps, there is a situation where the die-casting is placed upside down. When the upside-down die-casting is clamped by the clamp and enters the next station, the tool is not accurate enough in processing the die-casting, which makes the processing accuracy of the die-casting low. At the same time, it is easy to cause the tool to process the position of the die-casting that does not need to be processed, which leads to the problem of tool damage.

Otherwise, the horizontal driving member works to make the die-casting move along the extension direction of the guide rail and then enter the next workstation, thereby improving the accuracy of the clamping of the die-casting and thereby improving the yield rate of the die-casting processing in the subsequent workstations.

[0032] In order to better understand the technical solutions and beneficial effects of the present invention, the present invention is further described in detail below in conjunction with specific embodiments:

[0033] like Figure 1 , Figure 2 and Figure 4As shown, an automatic clamping device 10 of an embodiment includes a frame 100, a horizontal driving member 200, a guide bar 300 and a clamping assembly 400. The horizontal driving member 200 and the guide bar 300 are both installed on the frame 100, and the guide bar 300 is arranged adjacent to the horizontal driving member 200. Further, the automatic clamping device 10 also includes an anti-foolproofing induction detection member 500, and the clamping assembly 400 includes a first clamping plate 410, a second clamping plate 420 and a bottom plate 430. The power output end of the horizontal driving member 200 is connected to the bottom plate 430. The first clamping plate 410 and the second clamping plate 420 are respectively installed at both ends of the bottom plate 430. The first clamping plate 410 is provided with a first positioning clamping groove 411, and the second clamping plate 420 is provided with a second positioning clamping groove 421. The first positioning clamping groove 411 and the second positioning clamping groove 421 are arranged correspondingly. Specifically, The notch of the first positioning clamping groove 411 is arranged opposite to the notch of the second positioning clamping groove 421, and the first positioning clamping groove 411 and the second positioning clamping groove 421 are used together to clamp the die-casting. The bottom plate 430 is slidably connected to the guide bar 300, and the anti-foolproofing sensing detection component 500 is installed on the first clamping plate 410. The anti-foolproofing sensing detection component 500 is electrically connected to the horizontal driving component 200, and the anti-foolproofing sensing detection component 500 is used to detect the clamping direction of the die-casting so that the horizontal driving component 200 drives the bottom plate 430 to move along the extension direction of the guide bar 300.

[0034] In this embodiment, there are two guide rails 300, and the horizontal driving member 200 is located between the two guide rails 300. The horizontal driving member 200 drives the bottom plate 430 to move along the extension direction of the guide rails 300, thereby driving the die-casting on the bottom plate 430 to move. The first clamping plate 410 and the second clamping plate 420 are respectively located at the two ends of the top of the bottom plate 430, and the first positioning clamping groove 411 and the second positioning clamping groove 421 are used together to clamp and position the die-casting, so that the die-casting is fixed between the first clamping plate 410 and the second clamping plate 420. Further, the foolproof sensing detection member 500 is installed on the first clamping plate 410. The foolproof sensing detection member 500 detects the side of the die-casting close to the first clamping plate 410, and because the outer contours of the two sides of the die-casting are inconsistent, it can detect whether the die-casting is installed upside down. When the external equipment robot fixes the die-casting on the first clamping plate 410 and the second clamping plate 420, if the anti-foolproof sensing detection component 500 detects that the die-casting is installed upside down, the anti-foolproof sensing detection component 500 releases a signal to the horizontal driving component 200, and controls the horizontal driving component 200 to stop working, and manually adjusts the die-casting; on the contrary, if the die-casting is installed correctly, the anti-foolproof sensing detection component 500 releases a signal to control the horizontal driving component 200 to work, and then transports the die-casting to the next workstation.

[0035] It should be noted that the method of detecting the outer contour of the die-casting by the anti-foolproof sensing detection component 500 and the control method of controlling the movement of the horizontal driving component 200 are both prior arts and are not within the protection scope of this application. This application only protects the structure and position connection relationship of the device.

[0036] In the above-mentioned automatic clamping device 10, the power output end of the horizontal driving member 200 is connected to the base plate 430, the first clamping plate 410 and the second clamping plate 420 are installed at the two ends of the top of the base plate 430, and the external manipulator places the die-casting on the base plate 430, and the two ends are fixed by the first positioning clamping groove 411 and the second positioning clamping groove 421. The anti-foolproofing sensing detection member 500 is installed on the first clamping plate 410. The anti-foolproofing sensing detection member 500 detects the outer contour of the die-casting to determine whether the die-casting is installed upside down. When the anti-foolproofing sensing detection member 500 detects that the die-casting is installed upside down, the anti-foolproofing sensing detection member 500 releases a signal to stop the horizontal driving member 200. Otherwise, the horizontal driving member 200 works to move the die-casting along the extension direction of the guide bar 300, and then enters the next workstation, thereby improving the accuracy of the clamping of the die-casting, and thereby improving the yield rate of the die-casting processing in the subsequent workstations.

[0037] like Figure 4 As shown, in one embodiment, the foolproof inductive detection member 500 includes a connecting plate 510 and a sensor 520, wherein the connecting plate 510 is connected to the first clamping plate 410, and the sensor 520 is mounted on the connecting plate 510. In this embodiment, the sensor 520 is a contour sensor 520, so as to detect the contour of the die casting near the first clamping plate 410, and then determine whether the die casting is installed upside down.

[0038] like Figure 4 As shown, in one embodiment, the number of the first positioning clamping grooves 411 is multiple, the number of the second positioning clamping grooves 421 is multiple, the number of the sensors 520 is multiple, the multiple first positioning clamping grooves 411 and the multiple second positioning clamping grooves 421 are arranged one by one, the multiple sensors 520 are all located on the connecting plate 510, and each of the sensors 520 is used to detect the clamping direction of the die-castings located in the first positioning clamping grooves 411 and the second clamping grooves. It can be understood that the first clamping plate 410 is provided with multiple first positioning clamping grooves 411, the second clamping plate 420 is provided with multiple second positioning clamping grooves 421, the multiple sensors 520 are all located on the connecting plate 510, and each sensor 520 is used to detect the die-castings in the corresponding first positioning clamping grooves 411 and the second positioning clamping grooves 421, that is, the manipulator can grab multiple die-castings into the clamping assembly 400 at the same time, and judge whether the clamping is correct through multiple sensors 520, thereby improving production efficiency.

[0039] like Figure 5As shown, in one embodiment, the bottom plate 430 includes a bottom plate body 431, a sliding seat 432 and a connecting seat 433, the connecting seat 433 and the sliding seat 432 are respectively connected to the bottom of the bottom plate body 431, the first clamping plate 410 and the second clamping plate 420 are installed on the top of the bottom plate body 431, the connecting seat 433 is connected to the power output end of the horizontal driving member 200, the sliding seat 432 is provided with a sliding guide groove 432a, and the guide rail 300 is embedded in the sliding guide groove 432a so that the guide rail 300 is slidably connected with the sliding seat 432. It can be understood that when the power output end of the horizontal driving member 200 is working, the connecting seat 433 is driven to move, thereby driving the bottom plate body 431 and the sliding seat 432 to move, and the guide rail 300 and the sliding guide groove 432a cooperate with each other to play a guiding role.

[0040] In one embodiment, the bottom plate further comprises a screw connection member, the bottom plate body is provided with a first screw connection hole, the sliding seat is provided with a second screw connection hole, and the screw connection member passes through the first screw connection hole and the second screw connection hole in sequence, so that the sliding seat is screwed to the bottom plate body. In this embodiment, the screw connection member is a screw, and the bottom plate body and the sliding seat are fixed by the screw.

[0041] like Figure 5 As shown, in one embodiment, the connecting seat 433 is connected to the edge of the base body 431 so that the output end of the horizontal driving member 200 can better push the base body 431 to move.

[0042] like Figure 2 , Figure 3 and Figure 5 As shown, in one embodiment, the connecting seat 433 is provided with a position-avoiding groove 433a, and the horizontal driving member 200 has an output shaft 210 and a clamping sleeve 220, the clamping sleeve 220 is sleeved on the output shaft 210, the output shaft 210 passes through the position-avoiding groove 433a, and the clamping sleeve 220 is clamped with the connecting seat 433. It can be understood that the horizontal driving member 200 also includes a horizontal driving motor arranged on the frame, and the motor telescopic rod of the horizontal driving motor is the output shaft 210. When the horizontal driving member 200 is working, the output shaft 210 telescopically moves and drives the clamping sleeve 220 to move accordingly, and because the clamping sleeve 220 is clamped with the connecting seat 433, the connecting seat 433 moves together.

[0043] like Figure 3As shown, in one embodiment, the clamping sleeve 220 includes a first clamping sleeve 221 and a second clamping sleeve 222, the first clamping sleeve 221 and the second clamping sleeve 222, the first clamping sleeve 221 and the second clamping sleeve 222 are both sleeved on the output shaft 210, and the distance between the first clamping sleeve 221 and the second clamping sleeve 222 forms a clamping gap, and the connecting seat 433 is located in the clamping gap. In this embodiment, the connecting seat 433 is clamped by the first clamping sleeve 221 and the second clamping sleeve 222, so that the output shaft 210 telescopic movement drives the connecting seat 433 to move together.

[0044] In one embodiment, the horizontal driving member 200 is a motor. In other embodiments, the horizontal driving member 200 can also be a cylinder.

[0045] The present application also provides a die-casting processing equipment, comprising the automatic clamping device 10 described in any of the above embodiments.

[0046] Compared with the prior art, the present invention has at least the following advantages:

[0047] In the above-mentioned automatic clamping device 10, the power output end of the horizontal driving member 200 is connected to the base plate 430, the first clamping plate 410 and the second clamping plate 420 are installed at the two ends of the top of the base plate 430, and the external manipulator places the die-casting on the base plate 430, and the two ends are fixed by the first positioning clamping groove 411 and the second positioning clamping groove 421. The anti-foolproofing sensing detection member 500 is installed on the first clamping plate 410. The anti-foolproofing sensing detection member 500 detects the outer contour of the die-casting to determine whether the die-casting is installed upside down. When the anti-foolproofing sensing detection member 500 detects that the die-casting is installed upside down, the anti-foolproofing sensing detection member 500 releases a signal to stop the horizontal driving member 200. Otherwise, the horizontal driving member 200 works to move the die-casting along the extension direction of the guide bar 300, and then enters the next workstation, thereby improving the accuracy of the clamping of the die-casting, and thereby improving the yield rate of the die-casting processing in the subsequent workstations.

[0048] The above-mentioned embodiments only express several implementation methods of the present disclosure, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present disclosure, and these all belong to the protection scope of the present disclosure. Therefore, the protection scope of the patent of the present disclosure shall be based on the attached claims.
