Description

Technical Field

[0001] The present invention relates to the field of machining equipment, and in particular to a rapid replacement structure for the workbench of a horizontal machining center for automotive parts. Background Art

[0002] In the manufacturing process of automotive front and rear subframes, machining is often involved. Generally, a workpiece to be machined is installed on a workbench through a machine tool fixture, so that the workpiece to be machined is located at a fixed and correct position, facilitating more accurate positioning and cutting of the workpiece by a tool.

[0003] In the related art, the Chinese utility model patent with the publication number CN215280967U discloses a machine tool clamping device, including a workbench; and a clamping assembly, including two clamping structures oppositely and spaced apart in the left-right direction and installed at the upper end of the workbench. Each clamping structure includes a mounting seat provided at the upper end of the workbench, a fixing member detachably installed on the mounting seat, and a holding rod provided on the fixing member. At least one holding rod is movably installed in the corresponding fixing member in the left-right direction, so that the distance between the two holding rods is adjustable for jointly clamping a workpiece located between the two holding rods; the holding rod includes a rod body and a holding cap detachably installed at the end of the rod body, and the two holding caps are used to jointly clamp the workpiece.

[0004] In view of the above related art, when the workpiece on the machine tool is processed, the staff needs to rotate the rod body in sequence to separate the holding cap from the workpiece, so that the workpiece can be removed from the machine tool workbench. After removing the processed workpiece, a new workpiece to be processed is placed on the mounting seat, and then the rod body is rotated in the reverse direction so that the holding cap can clamp the workpiece. During the installation and disassembly of the workpiece, it is necessary to rotate multiple rod bodies repeatedly, making the installation and disassembly process of the workpiece relatively cumbersome, reducing the disassembly and assembly efficiency of the workpiece, and thus reducing the processing efficiency of the workpiece. Summary of the Invention

[0005] In order to improve the disassembly and assembly efficiency of the workpiece and thus improve the processing efficiency of the workpiece, the present application provides a rapid replacement structure for the workbench of a horizontal machining center for automotive parts.

[0006] The rapid replacement structure for the workbench of a horizontal machining center for automotive parts provided by the present application adopts the following technical solutions:

[0007] A quick replacement structure for the workbench of a horizontal machining center for automotive parts, including a workbench, on which a workpiece is installed. A rotating seat for driving the workbench to turn is arranged on one side of the workbench. Accommodation grooves are provided on both the top surface and the bottom surface of the workbench. Installation templates for installing workpieces are installed in both of the accommodation chutes. A locking device for preventing the installation template from detaching from the accommodation groove is arranged on the workbench. A sliding groove is provided on the side surface of the accommodation groove, and a locking groove is provided on the side surface of the installation template. The locking device includes a locking pin whose one end can be inserted into the locking groove. The locking pin is slidably arranged in the sliding groove. The locking device further includes a driving mechanism for driving one end of the locking pin to be inserted into the locking groove and a reset mechanism for pulling the locking pin out of the locking groove.

[0008] By adopting the above technical solution, accommodation grooves are provided on both the top surface and the bottom surface of the workbench, and installation templates are slidably arranged in the accommodation grooves. When the workpiece on one side is being processed, the staff can remove another installation template and install a new workpiece to be processed by taking advantage of the machining time of the machine tool. Then, the installation template with the new workpiece to be processed is installed in the accommodation groove on the other side of the workbench. At this time, the driving mechanism pushes the locking pin, so that one end of the locking pin is inserted into the locking groove, thereby preventing the installation template from detaching from the accommodation groove, and further fixing the position of the workpiece. When the processed workpiece is completed, the rotating seat drives the workbench to rotate half a circle, so that the newly installed workpiece is in the machining position. At this time, the reset mechanism drives the sliding pin, so that the installed template that has been processed can slide out of the accommodation groove, and the replacement installation work of the workpiece is carried out by using the machining time of the machine tool for the workpiece, improving the efficiency of workpiece disassembly and assembly, and thus improving the machining efficiency of the workpiece.

[0009] Preferably, an annular sliding groove is provided on the inner peripheral wall of the sliding groove. A retaining ring is installed at the end of the locking pin away from the locking groove. The reset mechanism includes an attracting block fixed to the retaining ring and an electromagnet for generating an attractive force on the attracting block. The electromagnet is fixed to the end wall of the annular sliding groove away from the locking groove. The reset mechanism further includes a control component for controlling the on-off of the electromagnet circuit.

[0010] By adopting the above technical solution, the attracting block is fixed on the retaining ring, and the electromagnet is fixed on the end wall of the annular chute away from the locking groove. When the workbench drives the workpiece to be flipped to the working position, the control component controls the disconnection of the electrical circuit of the electromagnet, so that the sliding pin is inserted into the locking groove under the driving action of the driving mechanism, preventing the mounting template from detaching from the workbench, and thus enabling the workpiece to be stably in the machining position. After the workpiece is machined, the workbench drives the machined workpiece and the mounting template to be flipped downward, making the electrical circuit of the electromagnet conduct again, so that the electromagnet generates an attractive force on the attracting block, thereby causing the attracting block to drive the locking pin to slide away from the mounting template, making the locking pin disengage from the locking groove, facilitating the disassembly of the mounting template.

[0011] Preferably, a control chute is formed on the side surface of the workbench close to the rotating seat. The control component includes a control block slidably disposed in the control chute and an elastic member for preventing the control block from sliding into the control chute. A fixed contact is embedded on the inner wall of the control chute, and a moving contact for contacting the fixed contact is embedded on the side surface of the control block. A power supply is installed on the workbench. One end of the internal coil of the electromagnet is electrically connected to the fixed contact, and the other end of the internal coil of the electromagnet is electrically connected to one electrode of the power supply. The other electrode of the power supply is electrically connected to the moving contact.

[0012] By adopting the above technical solution, the control block is slidably disposed in the control chute. One end of the internal coil of the electromagnet is electrically connected to the fixed contact, the other end of the internal coil of the electromagnet is electrically connected to one electrode of the power supply, and the other electrode of the power supply is electrically connected to the moving contact. When the workpiece to be machined located below the workbench is flipped to the machining position, under the elastic force of the elastic member, one end of the control block protrudes outside the control chute. At this time, the moving contact is separated from the fixed contact, so that the sliding pin is inserted into the locking groove under the driving action of the driving mechanism, preventing the mounting template from detaching from the workbench, and thus enabling the workpiece to be stably in the machining position. After the workpiece located above the workbench is machined, the rotating seat drives the workbench together with the workpiece to be flipped. When the control block corresponding to the workpiece located below the workbench after flipping is pushed into the control chute, the moving contact contacts the fixed contact. At this time, the locking pin disengages from the locking groove on the mounting template, releasing the locking of the mounting template, facilitating the disassembly of the mounting template.

[0013] Preferably, a trigger plate is fixed on the side surface of the rotating seat close to the workbench. A first inclined surface for abutting against the control block is provided on the trigger plate, and the side surface of the trigger plate away from the rotating seat abuts against the side surface of the workbench.

[0014] By adopting the above technical solution, during the process of the workpiece processed above the workbench flipping downward, the control block will abut against the first inclined surface on the trigger plate. As the workbench flips, under the abutting action between the control block and the first inclined surface, the control block gradually slides into the control chute against the elastic force of the elastic member, so that the moving contact piece contacts the fixed contact piece. And when the workpiece located below the workbench flips upward, the corresponding control block gradually disengages from the trigger plate, and under the elastic force of the elastic member, the moving contact piece is separated from the fixed contact piece.

[0015] Preferably, the elastic member is a first spring. One end of the first spring is fixed on the side surface of the control chute away from the rotating seat, and the other end of the first spring is fixed on the side surface of the control block away from the rotating seat.

[0016] By adopting the above technical solution, one end of the first spring is fixed on the side surface of the control chute away from the rotating seat, and the other end of the first spring is fixed on the side surface of the control block away from the rotating seat, so that the first spring can apply an elastic force to the control block to hinder the control block from sliding into the control chute.

[0017] Preferably, a strip-shaped chute is provided on the inner wall of the accommodating groove. The strip-shaped chute and the accommodating groove are both communicated with the side surface of the workbench. A limiting block is installed on the side surface of the installation template. The limiting block is slidably arranged in the strip-shaped chute. A protection device for preventing the limiting block from disengaging from the strip-shaped chute is provided on the workbench.

[0018] By adopting the above technical solution, the strip-shaped chute and the accommodating groove are both communicated with the side surface of the workbench, and the limiting block is slidably arranged in the strip-shaped chute, which facilitates the disassembly and installation of the installation template.

[0019] Preferably, a limiting chute is provided on the side wall of the strip-shaped chute away from the accommodating groove. The protection device includes a retaining strip slidably arranged in the limiting chute and a second spring located in the limiting chute. One end of the second spring is fixed on the end wall of the limiting chute away from the accommodating groove, and the other end of the second spring is fixed on the retaining strip. The retaining strip is used to abut against the limiting block.

[0020] By adopting the above technical solution, the limiting chute is provided on the side wall of the strip-shaped chute, and the retaining strip is slidably arranged in the limiting chute. Under the elastic force of the second spring, one end of the retaining strip is located outside the limiting chute. After the retaining strip is pushed into the limiting chute, the limiting block can slide in the strip-shaped chute, which facilitates the installation of the installation template. When the limiting block slides past the limiting chute, the end of the retaining strip away from the second spring slides out of the limiting chute under the elastic force of the second spring and abuts against the limiting block, thereby hindering the movement of the installation template during the flipping of the workbench and improving the stability of the installation template on the workbench.

[0021] Preferably, a clamping groove is provided on the side of the strip slide close to the workpiece, and a clamping mechanism is provided in the clamping groove. The clamping mechanism includes a clamping rod slidably arranged in the clamping groove and a thrust piece for pushing the clamping rod toward the limiting block, and the end of the clamping rod is used to interfere with the limiting block.

[0022] By adopting the above technical solution, the clamping rod is slidably set in the clamping groove. When the mounting template is installed in place, the thrust piece can generate thrust on the thrust piece, so that the end of the clamping rod contacts the limiting block, hindering the movement of the limiting block, and further improving the stability of the mounting template on the workbench.

[0023] Preferably, the sliding groove is connected with the clamping groove, and a connecting hole connected with the sliding groove is provided on the clamping rod, and a second inclined surface is provided on the side of the connecting hole close to the thrust piece, and the second inclined surface faces the side close to the mounting template, and the locking pin passes through the connecting hole, and a yielding groove is provided on the side wall of the clamping groove, and the yielding groove is connected with the sliding groove, and an unlocking block is slidingly provided in the yielding groove, and the unlocking block is fixed to the locking pin, and a third inclined surface is provided on the unlocking block for interfering with the second inclined surface.

[0024] By adopting the above technical solution, the locking pin passes through the connecting hole, and the unlocking block is fixed to the locking pin. When the reset mechanism drives the locking pin to slide in the direction away from the locking groove, the third inclined surface can interfere with the second inclined surface, and as the locking pin continues to slide, the unlocking block can push the clamping rod in the direction away from the limiting block through the interference between the third inclined surface and the second inclined surface, so that the locking pin disengages from the locking groove and the clamping rod releases the interference with the limiting block, thereby facilitating the replacement of the installation template.

[0025] Preferably, the thrust member is a third spring, one end of the third spring abuts against the inner wall of the pressing groove away from the limiting block, and the other end of the third spring abuts against the end face of the pressing rod.

[0026] By adopting the above technical solution, one end of the third spring abuts against the inner wall of the clamping slot away from the limiting block, and the other end of the third spring abuts against the end face of the clamping rod. Under the thrust of the third spring, the end of the clamping rod can be tightly pressed against the limiting block.

[0027] In summary, the present application includes at least one of the following beneficial technical effects:

[0028] 1. The top and bottom surfaces of the workbench are provided with receiving grooves, and mounting templates are slidably arranged in the receiving grooves. When the workpiece on one side is being processed, the staff can use the processing time of the machine tool to remove the other mounting template and install the new workpiece to be processed, and then install the mounting template with the new workpiece to be processed into the receiving groove on the other side of the workbench. At this time, the driving mechanism pushes the locking pin so that one end of the locking pin is inserted into the locking groove, thereby preventing the mounting template from being separated from the receiving groove, thereby fixing the position of the workpiece. When the workpiece being processed is completed, the rotating seat drives the workbench to rotate half a circle so that the newly installed workpiece is in the processing position. At this time, the reset mechanism drives the sliding pin so that the processed mounting template can slide out of the receiving groove, and the time when the machine tool is processing the workpiece is used to replace and install the workpiece, thereby improving the efficiency of workpiece disassembly and assembly, thereby improving the processing efficiency of the workpiece;

[0029] 2. The control block is slidably arranged in the control slide groove, the fixed contact piece is electrically connected to one end of the internal coil of the electromagnet, the other end of the internal coil of the electromagnet is electrically connected to one of the electrodes of the power supply, and the other electrode of the power supply is electrically connected to the moving contact piece. When the workpiece to be processed located below the workbench is flipped to the processing position, under the elastic force of the elastic member, one end of the control block protrudes from the outside of the control slide groove. At this time, the moving contact piece is disengaged from the fixed contact piece, so that the sliding pin is inserted into the locking groove under the driving action of the driving mechanism, preventing the installation template from leaving the workbench, thereby allowing the workpiece to be stably in the processing position. After the workpiece located above the workbench is processed, the rotating seat drives the workbench to flip together with the workpiece, and when the control block corresponding to the flipped workpiece located below the workbench is pushed into the control slide groove, the moving contact piece contacts the fixed contact piece. At this time, the locking pin disengages from the locking groove on the installation template, releasing the lock on the installation template, making it easier to disassemble the installation template.

[0030] 3. As the workpiece processed above the workbench flips downward, the control block comes into contact with the first inclined surface of the trigger plate. As the workbench flips, the control block, under the interference of the first inclined surface, overcomes the elastic force of the elastic member and gradually slides into the control slot, bringing the movable contact piece into contact with the fixed contact piece. During the flip, the workpiece to be processed below the workbench flips upward, and the corresponding control block gradually disengages from the trigger plate. Under the elastic force of the elastic member, the movable contact piece disengages from the fixed contact piece. BRIEF DESCRIPTION OF THE DRAWINGS

[0058] The implementation principle of the quick replacement structure of the workbench of a horizontal machining center for automotive parts in the embodiment of the present application is as follows: when the workbench 1 drives the workpiece 200 to flip from bottom to top to the working position, the control component 433 controls the electric circuit of the electromagnet 432 to be disconnected, so that the sliding pin is inserted into the locking groove 22 under the driving action of the driving mechanism 42, preventing the mounting template 2 from detaching from the workbench 1, and thus enabling the workpiece 200 to be stably in the machining position. After the workpiece 200 is machined, the workbench 1 drives the machined workpiece 200 and the mounting template 2 to flip downward, making the electric circuit of the electromagnet 432 conduct again, so that the electromagnet 432 generates an attractive force on the attracting block 431, thereby enabling the attracting block 431 to drive the locking pin 41 to slide in a direction away from the mounting template 2, so that the locking pin 41 disengages from the locking groove 22, facilitating the disassembly of the mounting template 2.

[0059] When the workpiece 200 above the workbench 1 is being processed, the staff can, during the machining time of the machine tool, remove the installation template 2 that has been flipped to the lower part of the workbench 1 and install a new workpiece 200 to be processed, and use the machining time of the machine tool for the replacement and installation work of the workpiece 200, improving the disassembly and assembly efficiency of the workpiece 200, and thus improving the machining efficiency of the workpiece 200.

[0060] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
