A control cabinet machining auxiliary positioning mechanism

Abstract

This utility model relates to the field of control cabinet processing technology, specifically, to an auxiliary positioning mechanism for control cabinet processing. It includes a base with a U-shaped frame mounted on its upper side. This utility model uses a lifting mechanism to drive the U-shaped frame vertically, adjusting the overall height to match the installation position of control cabinets of different sizes. Simultaneously, during the lifting of the U-shaped frame, the adjusting mechanism utilizes the meshing transmission between a large gear and a fixed second rack to drive a small gear to rotate, causing the two moving plates to move away from each other and automatically expanding the spacing between several clamping blocks. This increases the clamping area and disperses the support force, preventing cabinet door warping due to leverage. The feeding mechanism pushes the clamping plates horizontally via a threaded rod, pressing the control cabinet body and cabinet door firmly onto the clamping blocks, ensuring stable alignment of the hinge bolt holes and achieving stable clamping at key stress points. Ultimately, this maintains the relative positional stability of the cabinet door and cabinet body in three-dimensional space, improving the installation accuracy and efficiency of the cabinet door and cabinet body.

Description

Technical Field

[0001] This utility model relates to the field of control cabinet processing technology, and more specifically, to an auxiliary positioning mechanism for control cabinet processing. Background Technology

[0002] During the manufacturing process of the control cabinet, the cabinet door needs to be precisely installed onto the cabinet body. In order to ensure that the hinge bolt holes on the cabinet door and the cabinet body can be accurately aligned and the bolts can be smoothly inserted, the cabinet door and the cabinet body must be firmly fixed in space to prevent them from shifting during operation. The common practice is to rely on manual support or use simple support blocks for positioning.

[0003] However, existing fixing methods have shortcomings. This is mainly because the support area and clamping position of the support blocks or clamps used are often fixed. Their structure itself does not have the ability to automatically adjust according to the size of the cabinet door. When dealing with small cabinet doors, the fixed support points can cope, but when installing larger and heavier cabinet doors, the limited and fixed support area cannot distribute the support force, resulting in the support points being too concentrated. This can easily cause the part of the cabinet door outside the fixed points to warp or sway due to the lever principle. At the same time, the fixed clamping position cannot be adapted to the installation height of different cabinet door hinges, making it impossible to effectively clamp at key force points. As a result, it is difficult to stably maintain the relative position of the cabinet door and the cabinet body in three-dimensional space, ultimately affecting the accuracy and efficiency of the installation. Summary of the Invention

[0004] The purpose of this utility model is to provide an auxiliary positioning mechanism for control cabinet processing to solve the problems mentioned in the background art.

[0005] To address the above problems, the present invention aims to provide an auxiliary positioning mechanism for control cabinet processing, comprising a base, a U-shaped frame on the upper side of the base, a lifting mechanism for driving the U-shaped frame to move vertically on the upper side of the base, an assembly frame fixedly installed on the upper side wall of the U-shaped frame, two movable plates symmetrically slidably installed inside the assembly frame, and two clamping blocks fixedly installed on the sides of the two movable plates that are far apart from each other, and an adjustment mechanism for driving the two movable plates to move closer or further apart from each other inside the assembly frame. When the lifting mechanism drives the U-shaped frame to move upward, the adjustment mechanism drives the two movable plates to move further apart from each other. A clamping plate and a feeding mechanism are provided on the upper side of the U-shaped frame, and the feeding mechanism is used to drive the clamping plate closer or further away from the clamping blocks.

[0006] As a further improvement to this technical solution, the adjustment mechanism includes a large gear rotatably installed inside the assembly frame, and a second rack is fixedly installed on the upper side wall of the base, the second rack meshing with the large gear.

[0007] As a further improvement to this technical solution, a small gear is coaxially fixedly installed on one side of the large gear, and a third rack is meshed with both the front and rear sides of the small gear. One end of each of the two third racks is fixedly installed on two movable plates.

[0008] As a further improvement to this technical solution, the feeding mechanism includes two slide rods fixedly installed on the side of the clamp plate away from the assembly frame. Slide sleeves are slidably sleeved on the slide rods, and the slide sleeves are fixedly installed on the upper side wall of the U-shaped frame.

[0009] As a further improvement to this technical solution, a threaded rod is rotatably installed on the side of the clamp away from the assembly frame, and a nut is threaded onto the threaded rod, which is fixedly installed on the upper side wall of the U-shaped frame.

[0010] As a further improvement to this technical solution, the lifting mechanism includes a column and two guide rods that are vertically fixedly installed on the upper side wall of the base, and the U-shaped frame is slidably sleeved on the column and the two guide rods.

[0011] As a further improvement to this technical solution, a first rack is fixedly installed on one side of the column, and two side plates are fixedly installed on the upper side wall of the U-shaped frame. A rotating shaft is rotatably installed between the two side plates, and a drive gear is coaxially fixedly installed on the rotating shaft. The drive gear meshes with the first rack.

[0012] As a further improvement to this technical solution, one end of the rotating shaft rotates through the side plate and is fixedly mounted with a crank handle. The crank handle is threaded with a positioning pin, and several positioning grooves are arranged in a circular array around the rotating shaft on one of the side plates.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. The auxiliary positioning mechanism for the control cabinet machining uses a lifting mechanism to drive the U-shaped frame to move vertically, adjusting the overall height to match the installation position of control cabinets of different sizes. During the lifting of the U-shaped frame, the adjustment mechanism uses the meshing transmission of the large gear and the fixed second rack to drive the small gear to rotate, causing the two moving plates to move away from each other and automatically expanding the spacing of several clamping blocks, thereby increasing the clamping area and dispersing the support force, avoiding the cabinet door warping due to the leverage effect. The feeding mechanism pushes the clamping plate to move horizontally through the threaded rod, pressing the control cabinet body and cabinet door tightly onto the clamping blocks, ensuring stable alignment of the hinge bolt holes, and achieving stable clamping at key stress points. Ultimately, it maintains the relative positional stability of the cabinet door and cabinet body in three-dimensional space, improving the installation accuracy and efficiency of the cabinet door and cabinet body.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0017] Please see Figure 1 As shown, the purpose of this embodiment is to provide a control cabinet processing auxiliary positioning mechanism, including a base 1, a U-shaped frame 2 is provided on the upper side of the base 1, and a lifting mechanism 3 is provided on the upper side of the base 1 for driving the U-shaped frame 2 to move vertically. By adjusting the height of the U-shaped frame 2 through the lifting mechanism 3, the positioning requirements of control cabinets of different heights can be adapted.

[0018] The structure of lifting mechanism 3 is described in detail below, with reference to... Figure 2 and Figure 3The lifting mechanism 3 includes a column 32 and two guide rods 31 that are vertically fixedly installed on the upper side wall of the base 1. The U-shaped frame 2 is slidably sleeved on the column 32 and the two guide rods 31, so that the U-shaped frame 2 can only move in the vertical direction. A first rack 33 is fixedly installed on one side of the column 32. Two side plates 34 are fixedly installed on the upper side wall of the U-shaped frame 2. A rotating shaft 35 is rotatably installed between the two side plates 34. A drive gear 36 is coaxially fixedly installed on the rotating shaft 35. The drive gear 36 meshes with the first rack 33. One end of the rotating shaft 35 rotates through the side plate 34 and is fixedly installed with a crank handle 38. A positioning pin 39 is threadedly connected to the crank handle 38. Several positioning slots 37 are arranged in a ring array around the rotating shaft 35 on one of the side plates 34.

[0019] During operation, turning the crank handle 38 will drive the rotating shaft 35 and the drive gear 36 to rotate. With the meshing of the drive gear 36 and the first rack 33, the U-shaped frame 2 can be driven to move in the vertical direction. After the U-shaped frame 2 is adjusted to a suitable height, turn the crank handle 38 slightly to align the axis of the positioning pin 39 with the axis of any positioning groove 37. Then rotate the positioning pin 39 and use its threaded engagement with the crank handle 38 to insert the end of the positioning pin 39 into the positioning groove 37. This will restrict the rotation of the crank handle 38, the rotating shaft 35 and the drive gear 36, thereby locking the height of the U-shaped frame 2.

[0020] An assembly frame 6 is fixedly installed on the upper side wall of the U-shaped frame 2. Two movable plates 7 are symmetrically slidably installed inside the assembly frame 6. Two uprights are vertically fixed inside the assembly frame 6. The two ends of the movable plates 7 are slidably sleeved on the two uprights, restricting the movable plates 7 to only move vertically. Two clamping blocks 8 are fixedly installed on the sides of the two movable plates 7 that are far apart from each other. An adjustment mechanism 9 is provided inside the assembly frame 6 to drive the two movable plates 7 to move closer or further apart from each other. A clamping plate 4 and a feeding mechanism 5 are provided on the upper side of the U-shaped frame 2. The feeding mechanism 5 is used to drive the clamping plate 4 to move closer or further away from the clamping blocks 8.

[0021] In use, first align the cabinet door with the installation position on the control cabinet, then place the entire unit on the base 1 and within the internal space of the U-shaped frame 2. It should be noted that the initial height of the U-shaped frame 2 is precisely designed, roughly positioned in the middle of the door of a medium-sized control cabinet. When clamping and positioning larger control cabinets and doors, the lifting mechanism 3 moves the U-shaped frame 2 upwards. At this time, the adjusting mechanism 9 moves the two moving plates 7 away from each other, and the moving plates 7 move the clamping blocks 8 synchronously, widening the distance between the four clamping blocks 8 on the two moving plates 7. With the increased distance between the four clamping blocks 8, the clamping range correspondingly increases, enabling... It can better match the width of large cabinet doors, so that the clamping force is distributed over a wider area of ​​the cabinet door, avoiding the four clamping blocks 8 from applying pressure to the same area of ​​the cabinet door and causing the cabinet door to deform. This improves the overall clamping stability of all clamping blocks 8 on the cabinet door and cabinet body. When the U-shaped frame 2 moves to the approximate position of the middle of the cabinet door, the feeding mechanism 5 is activated to push the clamping plate 4 towards the clamping block 8. After the clamping plate 4 contacts the control cabinet body, it pushes the cabinet body and cabinet door closer to the clamping block 8 until the cabinet door and clamping block 8 are tightly fitted, clamping and fixing the control cabinet body and cabinet door. At this time, the hinge bolt holes on the cabinet door and control cabinet body can be stably aligned, which is convenient for bolt installation.

[0022] The structure of the adjustment mechanism 9 is described in detail below, with reference to... Figure 5 and Figure 6 The adjusting mechanism 9 includes a large gear 91 rotatably mounted inside the assembly frame 6. A second rack 92 is fixedly mounted on the upper side wall of the base 1. The second rack 92 meshes with the large gear 91. A small gear 93 is coaxially fixedly mounted on one side of the large gear 91. The outer diameter and number of teeth of the large gear 91 are both larger than the outer diameter and number of teeth of the small gear 93, thus forming a speed-increasing transmission pair. The front and rear sides of the small gear 93 are meshed with third racks 94. One end of each of the two third racks 94 is fixedly mounted on two moving plates 7. A through groove is opened on the moving plate 7 at the position corresponding to the second rack 92. The side of the second rack 92 away from the large gear 91 slides in contact with the inner wall of the through groove, limiting the second rack 92 from shifting and ensuring stable meshing between the second rack 92 and the large gear 91.

[0023] When the U-shaped frame 2 lifts the assembly frame 6, the large gear 91 inside the assembly frame 6 also rises, while the second rack 92 remains in a fixed position. This causes the large gear 91 to rotate through meshing transmission. The large gear 91 drives the small gear 93 to rotate synchronously. Since the large gear 91 has more teeth than the small gear 93, it forms a speed-increasing transmission pair, making the speed of the small gear 93 higher than that of the large gear 91. Therefore, within the same lifting stroke of the U-shaped frame 2, the small gear 93 can drive the two third racks 94 to generate a larger relative displacement of the moving plate 7, thereby quickly expanding the distance between the clamping blocks 8 on the two moving plates 7 to meet the clamping requirements of larger cabinet doors.

[0024] In addition, limit blocks can be installed on the large gear 91 at positions above and below the assembly frame 6 to limit the vertical movement of the assembly frame 6 to the upper and lower limits. This can prevent the assembly frame 6 from moving too much, causing the third rack 94 to disengage from the pinion 93, thereby ensuring the normal use of the adjustment mechanism 9.

[0025] The structure of feed mechanism 5 is described in detail below, with reference to... Figure 4 The feeding mechanism 5 includes two slide rods 51 fixedly installed on the side of the clamping plate 4 away from the assembly frame 6. Slide sleeves 52 are slidably sleeved on the slide rods 51. The slide sleeves 52 are fixedly installed on the upper side wall of the U-shaped frame 2, so that the clamping plate 4 can only move horizontally along the axis of the slide rods 51. A threaded rod 53 is rotatably installed on the side of the clamping plate 4 away from the assembly frame 6. A nut 54 is threadedly connected to the threaded rod 53. The nut 54 is fixedly installed on the upper side wall of the U-shaped frame 2. An external hexagon block is coaxially fixedly installed on the end of the threaded rod 53 away from the clamping plate 4. When the operator uses an electric wrench to rotate the external hexagon block and the threaded rod 53, the clamping plate 4 is moved horizontally towards the clamping block 8 through the cooperation of the threaded rod 53 and the nut 54, thereby contacting the control cabinet and achieving clamping and fixing.
