Description

Technical Field

[0001] This utility model relates to the field of automotive processing equipment technology, and in particular to a production device for an anti-deformation frame for a freezer door. Background Technology

[0002] The anti-deformation frame of a freezer door is a plastic frame embedded around the perimeter of the freezer door. After the anti-deformation frame is installed on the freezer door, holes need to be drilled during the production process to ensure a proper fit with the frame. Currently, drilling for the anti-deformation frame is mostly done manually with a handheld electric drill. This requires aligning the anti-deformation frame, marking points, and then drilling, making the entire process cumbersome and inefficient.

[0003] CN 214686937 U discloses a production apparatus for an anti-deformation frame of a freezer door, including a support mechanism and a drilling mechanism. The support mechanism includes a support frame and a support assembly. The drilling mechanism includes a moving assembly and a first drilling assembly. The moving assembly includes two moving seats, two moving slide rods, and a moving lead screw. The first drilling assembly includes a first drilling support and a first drilling drill. The first drilling support is slidably connected to both moving slide rods and threadedly connected to the moving lead screw. The first drilling drill is mounted on the first drilling support and is horizontally positioned. This production apparatus places the anti-deformation frame of the freezer door to be drilled onto the support assembly. Then, the first drilling drill is started, and the moving lead screw is rotated to move the first drilling support closer to the anti-deformation frame, allowing the first drilling drill to drill a hole in the anti-deformation frame. This reduces manual operation and improves production efficiency.

[0004] However, when the above-mentioned production device fixes the workpiece, it only drives the clamping block to press the upper surface of the frame by the clamping cylinder, and uses the friction between the clamping block and the frame to limit the workpiece laterally. This fixing method has poor stability. When drilling the frame, the frame is prone to lateral displacement, which affects the processing accuracy of the frame. In addition, the positioning block and the first drilling component need to be adjusted manually. The manual adjustment has poor accuracy and the adjustment process is cumbersome, resulting in the low production efficiency of the freezer door anti-deformation frame. Utility Model Content

[0005] In order to overcome the above-mentioned defects in the existing technology, this utility model provides a production device for anti-deformation frame of refrigerator door.

[0006] The technical solution adopted by this utility model to solve its technical problem is: a production device for anti-deformation frame of a freezer door, including a frame and a support mechanism. The support mechanism includes two sets of support plates, which are movably installed on the top of the frame. A movable block is movably installed on the support plate.

The sliders are slidably installed on the guide rails, which are fixedly installed on the frame. The guide rails extend along the length of the frame, and locking bolts are fitted on the front sliders.

[0009] Furthermore, the transverse drive mechanism includes two sets of horizontal plates, which are respectively fixedly installed on the front and rear sides of the frame. Several sets of first guide rods are fixedly installed between the two sets of horizontal plates. A first slide is fixedly installed on the first guide rod. The first slide is fixedly installed on the bottom of the mounting platform. A first lead screw nut is fixedly installed at the center of the bottom of the mounting platform. A first lead screw is fitted on the first lead screw nut. The first lead screw is rotatably installed on the horizontal plate. A first motor is fixedly installed on the front horizontal plate.

[0010] Furthermore, the drilling mechanism also includes a support base plate, the support frame is fixedly installed at one end of the support base plate near the support plate, a plurality of smooth rods are fixedly installed between the support frame and the support base plate, the drill bit assembly includes a drill bit support, the drill bit support is slidably installed on the smooth rod, the power output shaft of the electric telescopic rod is fixedly connected to the drill bit support, a drill bit seat is rotatably installed on the side of the drill bit support near the support frame, a gearbox is fixedly installed on the side of the drill bit support away from the support frame, and a drill motor is fixedly installed on the gearbox.

[0011] Furthermore, the bidirectional drive mechanism includes a bidirectional lead screw, with second lead screw nuts fitted at both ends of the bidirectional lead screw.

[0012] Furthermore, a control console is fixedly installed on the front side of the frame, and the control console is electrically connected to the cylinder, the first motor, the second motor, the electric telescopic rod, and the drill bit motor.

[0013] The beneficial effects of this utility model are that, through the design of a limiting platform on the side of the movable block, when the frame is clamped and fixed by the movable block and the fixed block, the limiting platform abuts against the inner side wall of the frame, thereby limiting the left and right sides of the frame and preventing the frame from shifting laterally during processing. This helps to improve the processing accuracy of the frame. Furthermore, the height of the drill bit assembly can be adjusted by the electric telescopic rod, which helps to improve the adjustment accuracy and speed of the drill bit assembly, thereby improving production efficiency.

[0022] To more clearly illustrate the technical solution of this utility model, the following description is made in conjunction with the accompanying drawings. Obviously, the drawings described below are only one embodiment of this utility model. For those skilled in the art, other embodiments can be obtained based on these drawings and embodiments without creative effort, and all of them fall within the protection scope of this utility model.

[0023] according to Figure 1-6 As shown, a production device for an anti-deformation frame of a freezer door includes a frame 1 and a support mechanism 2. The support mechanism 2 includes two sets of support plates 21. The support plates 21 are movably installed on the top of the frame 1. A movable block 22 is movably installed on the support plate 21. A limiting platform 221 is provided at one end of the movable block 22 near the outer side of the frame 1. A fixing block 23 is fixedly installed at the rear end of the support plate 21. A transverse drive mechanism 3 is provided below the support mechanism 2. A mounting platform 4 is provided on the transverse drive mechanism 3. Drilling mechanisms 5 are provided at both ends of the mounting platform 4. A bidirectional drive mechanism 6 for driving the drilling mechanism 5 to move is provided on the mounting platform 4. The drilling mechanism 5 includes a support frame 51. A drill bit assembly is movably installed on the support frame 51. An electric telescopic rod 52 for driving the drill bit assembly to move is fixedly installed on the top of the support frame 51.

[0024] In this embodiment, a groove 211 is provided at the rear end of the support plate 21. A connecting frame 24 is slidably installed in the groove 211. A movable block 22 is fixedly installed at the top of the connecting frame 24. A cylinder 25 is fixedly installed at the bottom of the support plate 21. The power output shaft of the cylinder 25 is fixedly connected to the bottom end of the connecting frame 24. The connecting frame 24 is driven to move in the groove 211 by the cylinder 25, so that the movable block 22 moves closer to the fixed block 23. Thus, the movable block 22 cooperates with the fixed block 23 to clamp and fix the frame.

[0025] In this embodiment, connecting seats 26 are fixedly installed at the front and rear ends of the support plate 21, and a slider 27 is fixedly installed at the bottom of the connecting seat 26. The slider 27 is slidably installed on the guide rail 28, which is fixedly installed on the frame 1. The guide rail 28 extends along the length of the frame 1. A locking bolt 29 is installed on the front slider 27. By loosening the locking bolt 29, the position of the support plate 21 on the frame 1 can be adjusted to process different specifications of the frame. When drilling is required on both sides of the frame at the same time, the distance between the two sets of support plates 21 and their adjacent drilling mechanisms 5 is adjusted to be equal. If drilling is only required on one side of the frame, the support mechanism 2 is moved closer to the drilling mechanism 5 on the drilling side.

[0026] In this embodiment, the transverse drive mechanism 3 includes two sets of horizontal plates 31, which are fixedly installed on the front and rear sides of the frame 1 respectively. Several sets of first guide rods 32 are fixedly installed between the two sets of horizontal plates 31. Preferably, there are two sets of first guide rods 32. A first slide block 33 is fixedly installed on the first guide rod 32. The first slide block 33 is fixedly installed on the bottom of the mounting platform 4.

The power output shaft of the first motor 36 is connected to the rotating shaft of the first lead screw 35 through a coupling. The first motor 36 drives the first lead screw 35 to rotate. With the cooperation of the first lead screw 35 and the first lead screw nut 34, the mounting platform 4 moves along the first guide rod 32, thereby adjusting the front and rear position of the drilling mechanism 5 to realize drilling processing at different positions of the frame.

[0027] In this embodiment, the drilling mechanism 5 further includes a support base plate 53, a support frame 51 fixedly installed at one end of the support base plate 53 near the support plate 21, and a plurality of sets of guide rods 54 fixedly installed between the support frame 51 and the support base plate 53. Preferably, there are two sets of guide rods 54, which are located at the front and rear ends of the support frame 51, respectively. The drill bit assembly includes a drill bit support 55, which is slidably installed on the guide rods 54. The power output shaft of the electric telescopic rod 52 is fixedly connected to the drill bit support 55. The drill bit support 55 is moved along the polished rod 54 by the electric telescopic rod 52, thereby adjusting the height of the drill bit assembly. A drill bit seat 56 is rotatably mounted on the side of the drill bit support 55 near the support frame 51, and a gearbox 57 is fixedly mounted on the side of the drill bit support 55 away from the support frame 51. A drill bit motor 58 is fixedly mounted on the gearbox 57, and a drill bit is mounted on the drill bit seat 56. The power of the drill bit motor 58 is transmitted to the drill bit seat 56 through the gearbox 57, thereby driving the drill bit to rotate for drilling.

[0028] In this embodiment, the bidirectional drive mechanism 6 includes a bidirectional lead screw 61, with second lead screw nuts 62 fitted at both ends of the bidirectional lead screw 61. The second lead screw nuts 62 are fixedly installed at the bottom of the adjacent support base plate 53. Second slide blocks 63 are fixedly installed at the front and rear ends of the bottom of the support base plate 53. The second slide blocks 63 are slidably mounted on the second guide rod 64. The second guide rod 64 is fixedly mounted on the mounting platform 4. A second motor 65 is fixedly mounted on the left side of the mounting platform 4 via a motor bracket. The power output end of the second motor 65 is connected to the rotating shaft of the bidirectional lead screw 61 via a coupling. The second motor 65 drives the bidirectional lead screw 61 to rotate. With the cooperation of the bidirectional lead screw 61 and the second lead screw nuts 62, the two sets of drilling mechanisms 5 move closer or further apart. By adjusting the position of the support mechanism 2 on the frame 1, drilling can be performed on both sides or one side of the frame.

[0029] In this embodiment, a control console 7 is fixedly installed on the front side of the frame 1. The control console 7 is connected to the cylinder 25, the first motor 36, the second motor 65, the electric telescopic rod 52 and the drill motor 58 through wires. Through the control console 7, the operator can automatically process the frame.

[0030] In use, the movable block 22 is driven by the cylinder 25 to move closer to the fixed block 23. The movable block 22 and the fixed block 23 work together to clamp and fix the frame. At the same time, the limiting platform 221 abuts against the inner side wall of the frame, thereby limiting the left and right sides of the frame and preventing lateral displacement of the frame during processing. This helps to improve the processing accuracy of the frame. When it is necessary to adjust the height of the drill hole, the drill bit support 55 is driven by the electric telescopic 52 to move along the guide rod, thereby adjusting the height of the drill bit assembly. This helps to improve the adjustment accuracy and speed of the drill bit assembly, thereby improving production efficiency.
