Description

Technical Field

[0001] This utility model relates to sheet metal processing technology, specifically to an adjustable sheet metal cutting fixture. Background Technology

[0002] Sheet metal parts are products manufactured using sheet metal processing technology. Sheet metal is a comprehensive cold working process for thin metal sheets. Cutting is an important step in the production of sheet metal parts. To ensure the stability of sheet metal parts during processing, fixtures are needed to fix them during cutting.

[0003] A search revealed that the Chinese patent "A Sheet Metal Part Cutting Fixture" (authorization announcement number CN218081454U) involves placing the sheet metal part on the upper surface of two sets of fixed plates, then activating an electric telescopic rod via a control panel. This telescopic rod moves an L-shaped connecting plate two, and the control panel then activates a hydraulic cylinder one to push a protective pad against the upper surface of the sheet metal part. This fixes the sheet metal part between the L-shaped connecting plate one and the L-shaped connecting plate two, thus minimizing movement of the sheet metal part during the cutting process.

[0004] Although the above application can fix sheet metal parts, since the fixing plate is fixed, the contact area of ​​the fixing plate supporting the sheet metal parts cannot be adjusted when fixing sheet metal parts of different sizes. When the size of the fixed sheet metal parts is large, the supporting area of ​​the fixing plate on the sheet metal parts is small, which affects the stability of the sheet metal parts during cutting.

[0005] Based on this, the present invention designs an adjustable sheet metal cutting fixture to solve the above problems. Utility Model Content

[0006] In view of the above-mentioned shortcomings of the existing technology, the present invention provides an adjustable sheet metal cutting fixture.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] An adjustable sheet metal cutting fixture includes an operating table. A movable plate is slidably connected to the top of the operating table. An electric push rod is fixedly connected to the top of the movable plate. A fixed plate is fixedly connected to the bottom of the electric push rod. Support plates are fixedly connected to opposite sides of the two movable plates. The fixture is characterized by having two adjustment mechanisms, each disposed on opposite sides of the two support plates. Each adjustment mechanism includes multiple connecting plates, which are hinged to opposite sides. One side of one connecting plate is hinged to the other side of a support plate. A circular block is fixedly connected to one end of each support plate and one end of each of the multiple connecting plates. Two locking holes are formed on the surface of each circular block.

[0009] Furthermore, the adjustment mechanism also includes a round rod fixedly connected to one end of the rotating shaft of the connecting plate, the other end of the round rod passing through a round block, a cylinder slidably connected to the surface of the round rod, a spring fixedly connected between the other end of the round rod and the inner wall of the cylinder, and a locking rod fixedly connected to one end of the cylinder.

[0010] Furthermore, the inner wall of the cylinder is provided with a sliding groove, and a limiting block is fixedly connected to the upper surface of the circular rod, with the surface of the limiting block slidably connected to the inner wall of the sliding groove.

[0011] Furthermore, the bottom end of the support plate and the bottom ends of the multiple connecting plates are all fixedly connected with limit rods, and the overall shape of the limit rods is "L".

[0012] Furthermore, a bidirectional lead screw is rotatably connected to one side of the inner wall of the operating table, and two sliders are threaded onto the surface of the bidirectional lead screw. The top of each slider is fixedly connected to the bottom of the corresponding moving plate.

[0013] Furthermore, the bottom end of the fixing plate, the top end of the support plate, and the top ends of the multiple connecting plates are all fixedly connected with contact pads, and the surface of the contact pads is provided with multiple grooves.

[0014] Furthermore, the opening of the card hole is funnel-shaped, and the diameter of the card rod matches the inner wall diameter of the card hole.

[0015] Furthermore, baffles are fixedly connected to both sides of the top of one of the support plates. Beneficial effects

[0016] 1. In this solution, when fixing sheet metal parts, two fixing plates and two support plates are used to fix the sheet metal parts. Under the action of the adjustment mechanism, it is convenient for the staff to select the appropriate number of connecting plates and support plates to connect. This allows for adjustment of the contact surface when supporting sheet metal parts of different sizes, improving the utilization of the device. When supporting larger sheet metal parts, multiple connecting plates and support plates are selected to form a whole to support the sheet metal parts, improving the support effect when fixing larger sheet metal parts and thus enhancing the stability when fixing sheet metal parts.

[0017] 2. Using two adjustment mechanisms and corresponding support plates to support the sheet metal parts helps to ensure that the surface of the sheet metal parts is evenly stressed after they are fixed, thus guaranteeing the cutting effect of the sheet metal parts. Attached Figure Description

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0027] The present invention will be further described below with reference to the embodiments.

[0028] In some embodiments, please refer to the appendix to the instruction manual. Figure 1-5An adjustable sheet metal cutting fixture includes an operating table 100, a movable plate 200 slidably connected to the top of the operating table 100, an electric push rod 300 fixedly connected to the top of the movable plate 200, a fixed plate 400 fixedly connected to the bottom of the electric push rod 300, and a support plate 500 fixedly connected to the opposite sides of the two movable plates 200.

[0029] In this embodiment of the utility model, a collection box is fixedly connected to the bottom of the operating table 100. An openable sealing plate is provided on one side of the collection box. When cleaning the collection box, the sealing plate can be opened. The width of the support plate 500 is smaller than the width of the collection box through groove.

[0030] A movable frame is mounted on one side of the top of the operating table 100 via an electric slide rail. A laser cutting machine is slidably connected to the surface of the movable frame. The laser cutting machine is installed on the electric slide rail set on the inner wall of the movable frame. The electric slide rail includes a motor, a lead screw, and a moving block. The motor is started by the controller, and the output shaft of the motor drives the lead screw to rotate, thereby causing the moving block to drive the corresponding movable frame and laser cutting machine to move. After the sheet metal part is fixed, the laser cutting machine can be started by the controller to cut the sheet metal part. The laser cutting motor does not interfere with the movable plate 200 during the cutting process.

[0031] Two adjustment mechanisms 600 are respectively disposed on opposite sides of two support plates 500. Each adjustment mechanism 600 includes multiple connecting plates 610, which are hinged to opposite sides. The other side of one of the connecting plates 610 is hinged to the other side of the support plate 500. A circular block 620 is fixedly connected to one end of the support plate 500 and one end of each of the multiple connecting plates 610. Two locking holes 621 are provided on the surface of the circular block 620.

[0032] In this embodiment of the utility model, the included angle between the center points of the two card holes 621 on the circular block 620 is 90 degrees. In the initial state, the multiple connecting plates 610 in the adjustment mechanism 600 are all in a horizontal state. The tops of the multiple connecting plates 610 and the tops of the support plate 500 are on the same horizontal plane, and the multiple connecting plates 610 in the adjustment mechanism 600 and the corresponding support plate 500 form an integral whole.

[0033] First, drive the two moving plates 200 to move according to the size of the sheet metal. After the moving plates 200 move to the appropriate position, place the sheet metal part on the two support plates 500 and the multiple connecting plates 610 of the two adjustment mechanisms 600. At this time, the operator can select the appropriate number of connecting plates 610 according to the size of the sheet metal part and keep them horizontal. Rotate the excess connecting plates 610 to the vertical position to avoid affecting the cutting of the sheet metal part. After the adjustment is completed, continue to drive the two moving plates 200 to move closer to each other to limit the sheet metal part from both sides. After this operation is completed, start the two electric push rods 300 through the controller to push the fixed plate 400 to move downward to clamp and fix the sheet metal part from the top.

[0034] Select the corresponding number of connecting plates 610 and support plates 500 to form a whole to support the sheet metal parts according to different sizes, so as to ensure the support effect when fixing sheet metal parts of different sizes and enhance the stability of fixing sheet metal parts.

[0035] In some embodiments, such as Figure 4-5 As shown, in a preferred embodiment of the present invention, the adjusting mechanism 600 further includes a round rod 630 fixedly connected to one end of the rotating shaft of the connecting plate 610, the other end of the round rod 630 passing through the round block 620, a cylinder 640 slidably connected to the surface of the round rod 630, a spring 650 fixedly connected between the other end of the round rod 630 and the inner wall of the cylinder 640, and a locking rod 660 fixedly connected to one end of the cylinder 640.

[0036] In this embodiment of the utility model, in the initial state, the locking rods 660 at one end of the multiple cylinders 640 engage with one of the locking holes 621 on the corresponding circular block 620, thereby connecting the multiple connecting plates 610 into a whole and simultaneously fixing the connecting plates 610 and the support plate 500.

[0037] When the excess connecting plate 610 is rotated to a vertical position, the cylinder 640 at one end of the corresponding connecting plate 610 is pulled away from the connecting plate 610. During the pulling process, the spring 650 is compressed, which causes the locking rod 660 to disengage from the corresponding locking hole 621. At this time, the operator rotates the cylinder 640, which drives the round rod 630 and the connecting plate 610 to rotate synchronously. When the excess connecting plate 610 is rotated to a vertical position, the operator releases the force on the cylinder 640. At this time, the spring 650 returns to its original position and drives the locking rod 660 to automatically return to its original position and enter another locking hole 621 on the corresponding round block 620, thus completing the fixation of the rotated connecting plate 610.

[0038] The interaction between the locking rod 660 and the two locking holes 621 is beneficial for fixing the connecting plate 610 in both states, ensuring the stability of the device during operation. Under the action of the cylinder 640 and the spring 650, it is also beneficial for the operator to complete the fixing of the connecting plate 610 synchronously after rotation, making the operation more convenient.

[0039] In some embodiments, such as Figure 5 As shown, in a preferred embodiment of the present invention, a groove 641 is provided on the inner wall of the cylinder 640, and a limiting block 642 is fixedly connected to the upper surface of the round rod 630. The surface of the limiting block 642 is slidably connected to the inner wall of the groove 641.

[0040] In this embodiment of the utility model, when the worker rotates the cylinder 640, the interaction between the slide groove 641 and the limiting block 642 will drive the rod 630 to rotate synchronously, thereby driving the corresponding connecting plate 610 to rotate.

[0041] The stability of the device during use is ensured by the action of the slide 641 and the limiting block 642.

[0042] In some embodiments, such as Figure 4-5 As shown, in a preferred embodiment of the present invention, the bottom end of the support plate 500 and the bottom ends of the multiple connecting plates 610 are all fixedly connected to a limiting rod 670, and the overall shape of the limiting rod 670 is "L".

[0043] In this embodiment of the utility model, when it is necessary to shorten the overall length of multiple connecting plates 610 in the adjustment mechanism 600, the connecting plates 610 at the corresponding positions are rotated. During the rotation, when the bottom end of the uppermost rotating connecting plate 610 in its initial state is in contact with the other end of the limiting rod 670, the rotating connecting plate 610 is in a vertical state.

[0044] This helps to limit the rotation angle of the connecting plate 610, so that the corresponding locking rod 660 of the connecting plate 610 can be better aligned with the locking hole 621 after rotation.

[0045] In some embodiments, such as Figure 2 As shown, in a preferred embodiment of the present invention, a bidirectional lead screw 110 is rotatably connected to one side of the inner wall of the operating table 100. Two sliders 120 are threadedly connected to the surface of the bidirectional lead screw 110. The top of the slider 120 is fixedly connected to the bottom of the corresponding moving plate 200.

[0046] In this embodiment of the utility model, the threads connecting the two sliders 120 and the bidirectional lead screw 110 are opposite. Therefore, when fixing the sheet metal parts, the operator rotates the bidirectional lead screw 110 to make the two sliders 120 drive the two moving plates 200 to move synchronously and move closer to each other to fix the sheet metal parts.

[0047] By setting two identical movable plates 200, it is beneficial to ensure that the surface of the sheet metal parts is subjected to uniform force after the sheet metal parts are fixed.

[0048] In some embodiments, such as Figure 3-4 As shown, in a preferred embodiment of the present invention, the bottom end of the fixing plate 400, the top end of the support plate 500 and the top ends of the multiple connecting plates 610 are all fixedly connected to contact pads 680, and the surface of the contact pads 680 is provided with multiple grooves.

[0049] In this embodiment of the utility model, the contact pad 680 is a rubber component. When fixing the sheet metal part, the contact pad 680 at the bottom of the fixing plate 400 contacts the top of the sheet metal part, and the contact pad 680 at the top of the support plate 500 and the connecting plate 610 contacts the bottom of the sheet metal plate.

[0050] The contact pad 680 helps to increase the friction between the fixing plate 400, the support plate 500, and the connecting plate 610 and the surface of the sheet metal part when fixing the sheet metal part, thereby enhancing the stability of fixing the sheet metal part.

[0051] In some embodiments, such as Figure 5 As shown, in a preferred embodiment of the present invention, the opening of the card hole 621 is funnel-shaped, and the diameter of the card rod 660 matches the inner wall diameter of the card hole 621.

[0052] In this embodiment of the utility model, the other end of the locking rod 660 is bent into an arc shape, which makes it easier for the locking rod 660 to enter the locking hole 621 to complete the locking.

[0053] In some embodiments, such as Figure 4 As shown, in a preferred embodiment of the present invention, baffles 510 are fixedly connected to both sides of the top end of one of the support plates 500.

[0054] In this embodiment of the utility model, when fixing the sheet metal part, when the sheet metal part is placed on the support plate 500, the two baffles 510 will limit the placement position of the sheet metal part, thereby ensuring the stability of fixing the sheet metal part.

[0055] It should be noted that the laser cutting machine, motor, and electric actuator mentioned above are all components with relatively mature existing technologies. The specific model can be selected according to actual needs. At the same time, the laser cutting machine, motor, and electric actuator can be powered by the built-in power supply or by AC power. The specific power supply method should be selected according to the situation, which will not be elaborated here.

[0056] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
