Description

Technical Field

[0001] This invention belongs to the field of engraving machine technology, and particularly relates to an engraving machine for processing mold parts. Background Technology

[0002] A CNC engraving machine is a type of CNC machine tool. It can perform non-contact cutting and drilling on metal or non-metal sheets and pipes, and is particularly suitable for laser cutting of materials such as stainless steel, iron, silicon wafers, ceramic sheets, titanium alloys, epoxy resin, A3 steel, and diamond.

[0003] When processing molds, precision engraving machines are often used to perform precision machining on the molds. Due to the heavy weight of the molds, hoisting equipment is needed to lift them onto the precision machining worktable. Then, tooling fixtures are used to fix the molds onto the moving mechanism on the worktable.

[0004] Because the engraving machine's worktable is equipped with an engraving head, the mold cannot be placed in the center of the tooling fixture in one go. Tools such as a copper hammer are needed to finely adjust the position of the mold. Furthermore, since the engraving machine's worktable has a movable height, there are safety hazards in lifting the mold to a high position using a hoisting device. Summary of the Invention

[0005] The purpose of this invention is to provide a CNC engraving machine table for processing mold parts, which aims to solve the problems that, since the CNC engraving machine table is equipped with an engraving head, it is impossible to place the mold in the center of the tooling fixture at once, and tools such as a copper hammer are needed to finely adjust the position of the mold. Furthermore, since the CNC engraving machine table has a movable height, there are safety hazards when the hoisting device lifts the mold to a high position.

[0006] This invention is implemented as follows: a precision engraving machine for processing mold parts includes a mounting plate, on which a support leg is fixed, and at the end of the support leg is a worktable surface, and further includes:

[0012] The transmission component is mounted on the movable frame and is used to drive the sliding wedge to retract into the second guide groove.

[0013] The clamping assembly is mounted on the clamping table and is used to fix the mold.

[0014] In a further technical solution, the workstation switching mechanism includes a guide component and a lifting component, both of which are mounted on a mounting plate. The guide component guides the movement of the support platform, and the lifting component drives the lifting frame to move up and down.

[0015] In a further technical solution, the guiding assembly includes a first guide plate and a first push shaft. The first guide plate is fixed on the mounting plate, and a fourth guide groove is provided on the first guide plate. The first push shaft is slidably connected to the fourth guide groove, and the first push shaft is fixed on the support platform.

[0016] In a further technical solution, the lifting assembly includes a telescopic cylinder, a connecting rod, a second guide plate, and a second push shaft. The telescopic cylinder and the connecting rod are both rotatably connected to the mounting plate. The telescopic end of the telescopic cylinder is rotatably connected to the middle part of the connecting rod. The end of the connecting rod is fixed with the second push shaft. The second guide plate is fixed on the lifting frame. A fifth guide groove is provided on the second guide plate. The second push shaft is slidably connected to the fifth guide groove.

[0017] A further technical solution includes a transmission assembly comprising a first slider, a first pull rope, a push rod, a tension spring, a mounting block, a steering wheel, a second pull rope, a push block, a push frame, and a guide rod. A first groove is provided on the side wall of the movable frame, and the first slider is slidably connected to the first groove. A wire groove is provided on the movable frame, and the first pull rope is disposed on the wire groove, with both ends of the first pull rope connected to the sliding wedge and the first slider, respectively. The push rod and the guide rod are both slidably connected to the worktable surface. The push frame is fixed to the lower end of the guide rod, and a limit block is installed on the upper end of the guide rod. Both ends of the tension spring are connected to the worktable surface and the lower end of the push rod, respectively. The mounting block is fixed to the lower end of the worktable surface, and the steering wheel is rotatably connected to the lower end of the mounting block. One end of the second pull rope is fixed to the lower end of the push rod, and the other end of the second pull rope passes around the steering wheel and is fixed to the push frame.

[0020] This invention provides a precision engraving machine for processing mold parts. A hoisting device places the mold on a clamping table, and a clamping assembly fixes the mold to the table. A station switching mechanism drives the clamping table to switch positions, first tilting the support platform to the upper right and then moving it vertically upwards. When the support platform and the clamping table extend into the moving frame, the contact transmission assembly restricts the movement of the sliding wedge. A first spring pushes the sliding wedge to move, inserting it into the connecting slot. At this point, the support platform stops moving upwards, and the sliding wedge pushes the inclined plane, causing the inclined plane to move the clamping table upwards, disengaging it from the placement slot (thus not affecting the horizontal movement of the clamping table) and fixing it in place. The moving assembly drives the moving frame to move horizontally, thus cooperating with the engraving head to perform precision engraving on the mold. This application allows the mold to be transported to the processing position from the outside of the worktable, simplifying mold loading and eliminating the need to hoist the mold to a high position, thereby improving the efficiency of mold precision engraving.

Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0029] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0030] like Figures 1-5 As shown, an embodiment of the present invention provides a precision engraving machine for processing mold parts, including a mounting plate 101, a support leg 102 fixed on the mounting plate 101, and a worktable 103 fixed to the end of the support leg 102, and further including:

[0031] The components include a movable frame 104, a clamping table 105, a first guide post 106, a lifting frame 107, a first guide groove 108, a support platform 109, a sliding wedge 112, a first spring 115, a workstation switching mechanism, a transmission assembly 4, a moving assembly 6, and a clamping assembly 7.

[0032] The movable frame 104 is mounted on the workbench 103 via the movable component 6, which is used to drive the movable frame 104 to move horizontally.

[0033] The first guide post 106 is fixed on the mounting plate 101, the lifting frame 107 is slidably connected to the first guide post 106, the lifting frame 107 is provided with a first guide groove 108, the support platform 109 is slidably connected to the first guide groove 108, the support platform 109 is provided with a placement groove 110, and the clamping table 105 is provided on the placement groove 110.

[0034] The movable frame 104 is provided with a second guide slide groove 111, and a sliding wedge 112 is slidably connected to the second guide slide groove 111. The clamping table 105 is provided with a connecting groove 113, and a pushing inclined surface 114 is provided on the connecting groove 113. The first spring 115 is provided on the second guide slide groove 111.

[0035] The workstation switching mechanism is mounted on the mounting plate 101, and the workstation switching mechanism is used to drive the clamping table 105 to switch workstations.

[0036] The transmission component 4 is disposed on the movable frame 104, and the transmission component 4 is used to drive the sliding wedge 112 to retract into the second guide groove 111;

[0037] The clamping assembly 7 is disposed on the clamping table 105 and is used to fix the mold.

[0038] In this embodiment of the invention, during use, a hoisting device is used to place the mold on the clamping table 105. The clamping assembly 7 fixes the mold on the clamping table 105. The station switching mechanism drives the clamping table 105 to switch positions, that is, it drives the support platform 109 to first tilt to the upper right corner and then move vertically upward. When the support platform 109 drives the clamping table 105 into the moving frame 104, it contacts the transmission assembly 4 to restrict the movement of the sliding wedge 112. The first spring 115 pushes the sliding wedge 112 to move, and the sliding wedge 112 inserts into the connecting groove 113. At this time, the support platform 109 stops moving upward, the sliding wedge 112 pushes the inclined plane 114, which in turn causes the inclined plane 114 to move the clamping table 105 upward, so that the clamping table 105 is disengaged from the placement slot 110 (therefore it does not affect the horizontal movement of the clamping table 105), and the clamping table 105 is fixed. The moving component 6 drives the moving frame 104 to move horizontally, and then cooperates with the engraving head to engrave the mold. This application can transport the mold to the processing position on the outside of the worktable 103, thereby simplifying the mold loading and improving the efficiency of mold engraving.

[0039] like Figures 1-4 As shown, in a preferred embodiment of the present invention, the workstation switching mechanism includes a guide component 2 and a lifting component 3. Both the guide component 2 and the lifting component 3 are mounted on the mounting plate 101. The guide component 2 is used to guide the movement of the support platform 109, and the lifting component 3 is used to drive the lifting frame 107 to move up and down. The guide component 2 includes a first guide plate 201 and a first push shaft 203. The first guide plate 201 is fixed on the mounting plate 101, and a fourth guide groove 202 is provided on the first guide plate 201. The first push shaft 203 is slidably connected to the fourth guide groove 202, and the first push shaft 203 is fixed on the support platform 109.

[0040] The lifting assembly 3 includes a telescopic cylinder 301, a connecting rod 302, a second guide plate 303, and a second push shaft 305. The telescopic cylinder 301 and the connecting rod 302 are rotatably connected to the mounting plate 101. The telescopic end of the telescopic cylinder 301 is rotatably connected to the middle part of the connecting rod 302. The end of the connecting rod 302 is fixed with the second push shaft 305. The second guide plate 303 is fixed to the lifting frame 107. A fifth guide groove 304 is provided on the second guide plate 303. The second push shaft 305 is slidably connected to the fifth guide groove 304.

[0041] In this embodiment of the invention, the support platform 109 is initially positioned at the left end of the first guide groove 108 and the fourth guide groove 202. The telescopic cylinder 301 extends and drives the connecting rod 302 to rotate. The connecting rod 302 pushes the lifting frame 107 to move upward through the fifth guide groove 304 and the second push shaft 305. When the lifting frame 107 moves upward, the support platform 109 moves along the trajectory of the fourth guide groove 202 under the guidance of the first push shaft 203, that is, it first moves tilted to the upper right corner and then moves vertically upward.

[0042] like Figures 1-5 As shown, in a preferred embodiment of the present invention, the transmission assembly 4 includes a first slider 402, a first pull rope 404, a push rod 405, a tension spring 406, a mounting block 501, a steering wheel 502, a second pull rope 503, a push block 504, a push frame 505, and a guide rod 506. A first groove 401 is provided on the side wall of the moving frame 104, and the first slider 402 is slidably connected to the first groove 401. A wire groove 403 is provided on the moving frame 104, and the first pull rope 404 is disposed on the wire groove 403. Both ends of the first pull rope 404 are respectively connected to the sliding wedge 112 and the first slider 402. The push rod... Both 405 and guide rod 506 are slidably connected to the worktable 103. The push frame 505 is fixed to the lower end of the guide rod 506. A limit block is installed on the upper end of the guide rod 506. The two ends of the tension spring 406 are respectively connected to the worktable 103 and the lower end of the push rod 405. The mounting block 501 is fixed to the lower end of the worktable 103. The steering wheel 502 is rotatably connected to the lower end of the mounting block 501. One end of the second pull rope 503 is fixed to the lower end of the push rod 405. The other end of the second pull rope 503 passes around the steering wheel 502 and is fixed to the push frame 505. The push block 504 is fixed to the support platform 109.

[0043] In this embodiment of the invention, the tension spring 406 pulls the push rod 405 upward, and the push rod 405 pushes the first slider 402 upward. The first slider 402 overcomes the elastic force of the first spring 115 and pulls the sliding wedge 112 into the second guide groove 111 through the wire groove 403. When the support platform 109 drives the clamping table 105 to move vertically upward, and the clamping table 105 extends into the moving frame 104, the support platform 109 pushes the push frame 505 upward through the push block 504. The push frame 505 pulls the push rod 405 downward through the second pull rope 503, thereby preventing the push rod 405 from pushing the first slider 402. At this time, the first pull rope 404 is not under force, and the first spring 115 pushes the sliding wedge 112 to move. The sliding wedge 112 inserts into the connecting groove 113. At this time, the support platform... 109 stops moving upward, and the sliding wedge 112 pushes the inclined plane 114, which in turn causes the inclined plane 114 to move the clamping table 105 upward, so that the clamping table 105 is disengaged from the placement groove 110 (therefore without affecting the horizontal movement of the clamping table 105), and the clamping table 105 is fixed. After the mold is finished, the support table 109 moves downward, so that the support table 109 does not push the push frame through the push block 504. The tension spring 406 pulls the push rod 405 upward, and the push rod 405 overcomes the elastic force of the first spring 115 and pushes the first slider 402. The first slider 402 pulls the sliding wedge 112 into the second guide groove 111 through the first pull rope 404. At this time, the clamping table 105 drives the mold to fall on the placement groove 110 of the support table 109.

[0044] like Figure 1 As shown, in a preferred embodiment of the present invention, the moving component 6 includes a side plate 601, a rotating shaft 602, a moving plate 603, and a transmission rod 605. The side plate 601 is fixed on the worktable 103. The rotating shaft 602 is rotatably connected to the side plate 601. The moving plate 603 is threadedly connected to the rotating shaft 602. A third guide groove 604 is provided on the moving plate 603. The moving frame 104 is slidably connected to the third guide groove 604. The transmission rod 605 is rotatably connected to the third guide groove 604 and threadedly connected to the moving frame 104. Servo motors are installed on both the side plate 601 and the moving plate 603, and the rotating ends of the two servo motors are respectively connected to the rotating shaft 602 and the transmission rod 605.

[0045] In this embodiment of the invention, when the servo motor drives the rotating shaft 602 or the transmission rod 605 to rotate, the rotating shaft 602 or the transmission rod 605 drives the moving plate 603 or the moving frame 104 to move through the threaded transmission, thereby driving the clamping table 105 to move horizontally, so as to facilitate the precision engraving machine head to perform precision engraving on the mold.

[0046] like Figure 1 and Figure 6As shown, in a preferred embodiment of the present invention, the clamping assembly 7 includes a first clamping plate 701, a fixing plate 702, a second clamping plate 703, and a lead screw 704. The first clamping plate 701 and the fixing plate 702 are both fixed on the clamping table 105. The second clamping plate 703 is slidably connected to the clamping table 105. The lead screw 704 is threadedly connected to the fixing plate 702, and one end of the lead screw 704 is rotatably connected to the second clamping plate 703.

[0047] In this embodiment of the invention, the mold is placed on the clamping table 105, and then the lead screw 704 is rotated. The lead screw 704 drives the second clamping plate 703 to move through the threaded transmission. The second clamping plate 703 cooperates with the first clamping plate 701 to fix the mold.

[0048] The above embodiments of the present invention provide a precision engraving machine for processing mold parts. In use, a hoisting device is used to place the mold on the clamping table 105. The lead screw 704 is rotated, and the lead screw 704 drives the second clamping plate 703 to move via a threaded transmission. The second clamping plate 703, in conjunction with the first clamping plate 701, fixes the mold. The telescopic cylinder 301 extends, driving the connecting rod 302 to rotate. The connecting rod 302 pushes the lifting frame 107 upward through the fifth guide groove 304 and the second push shaft 305. When the lifting frame 107 moves upward, the support platform 109 moves along the trajectory of the fourth guide groove 202 under the guidance of the first push shaft 203, i.e., first tilting to the upper right and then moving vertically upward. When the support platform 109 drives the clamping table 105 to move vertically upward, and the clamping table 105 extends into the moving frame 104, the support platform 109 pushes the pushing frame 505 upward through the push block 504. The pushing frame 505 is then pushed upward through the second pull rope 503. Pulling the push rod 405 downwards prevents it from pushing the first slider 402. The first pull rope 404 is then unloaded, and the first spring 115 pushes the sliding wedge 112 to move. The sliding wedge 112 inserts into the connecting groove 113, at which point the support platform 109 stops moving upwards. The sliding wedge 112 pushes the inclined plane 114, causing the inclined plane 114 to move the clamping platform 105 upwards, disengaging the clamping platform 105 from the placement groove 110 (thus not affecting the clamping platform 105). The servo motor drives the rotating shaft 602 or the transmission rod 605 to rotate, and the rotating shaft 602 or the transmission rod 605 drives the moving plate 603 or the moving frame 104 to move through the threaded transmission, thereby driving the clamping table 105 to move horizontally, so as to facilitate the precision engraving head to perform precision engraving on the mold. This application can transport the mold to the processing position on the outside of the worktable 103, thereby simplifying the mold loading and improving the efficiency of mold precision engraving.

[0049] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
