Description

Technical Field

[0001] This utility model relates to the field of fire door technology, specifically a positioning and clamping fixture for fire door processing. Background Technology

[0002] Fire doors are doors that can meet the requirements of fire resistance stability, integrity, and heat insulation within a certain period of time. They are fire-resistant partitions with a certain degree of fire resistance installed in fire compartments, evacuation stairwells, vertical shafts, etc., in buildings to isolate fire sources. They play a vital role in fire prevention, allowing people to escape through fire doors in the event of a fire. Fire doors require positioning and clamping fixtures for fixation during manufacturing.

[0003] The existing positioning and clamping fixtures have the following problems: The existing positioning and clamping fixture uses a moving column to drive the pressure head against the edge of the fire door, and then presses it against the baffle for positioning and clamping. In order to avoid damaging the door edge, the pressure head is made of rubber, which is prone to deformation or damage after long-term use. In order to avoid skewing during pushing, the pressure head needs to be replaced. However, the existing pressure head is not easy to disassemble and assemble, which leads to the problem of inconvenience in disassembly and assembly during replacement. Utility Model Content

[0004] The purpose of this invention is to provide a positioning and clamping fixture for fire door processing, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a positioning and pressing fixture for processing fire doors, comprising a frame, a guide roller disposed in the frame, a backing plate fixed on the surface of the frame, a driver disposed at the lower end of the frame, a moving column disposed on the driver, a pressing head disposed on the moving column, an installation structure disposed on the moving column, the installation structure comprising a column, a column disposed on the surface of the moving column, a locking rod connected in the column, an insert connected in the column, a sliding groove provided on the insert, a mating sleeve fixed in the pressing head, and a locking groove provided in the mating sleeve.

[0006] Preferably, the depths of the upper and lower ends of the groove are not the same.

[0007] Preferably, a bearing is fixed inside the mating sleeve, and the slot is located on the inner ring surface of the bearing.

[0008] Preferably, the slot is annular.

[0009] Preferably, a limit ring is provided on the surface of the clamp rod.

[0010] Preferably, the upper end of the insertion post is provided with an elastic plate, the surface of the elastic plate is provided with a locking block, and the inner side of the post is provided with a limiting groove.

[0011] Preferably, the elastic plate is in an unfolded state when it is in a natural, unforced state.

[0012] Compared with the prior art, the beneficial effects of this utility model are: During installation, the clamping head is placed on the column. Since the slot is annular, alignment is unnecessary, improving installation convenience. The insert is then pushed downwards, causing the sliding groove to move downwards. The clamping rod is located inside the sliding groove, allowing it to slide outwards within the column as the groove moves downwards, eventually engaging with the slot. The clamping block, under the action of the elastic plate, engages with the limiting groove, limiting the insert and facilitating easy installation. For disassembly, pressing the elastic plate moves the clamping block out of the limiting groove, releasing the limiting effect on the insert. The insert is then slid upwards, preventing the sliding groove from pushing the clamping rod, allowing the clamp to be removed for easy disassembly. This significantly improves the convenience of clamp replacement. Attached Figure Description

Detailed Implementation

[0015] To further explain the technical solution of this utility model, a detailed description is provided below through specific embodiments.

[0016] Please see Figure 1 and Figure 2 This utility model provides a positioning and pressing fixture for fire door processing, including a frame 1, a rotatably connected guide roller 2 in the frame 1, a backing plate 3 fixed on the surface of the frame 1, a driver 4 at the lower end of the frame 1, a moving column 5 on the driver 4, the moving column 5 serving as the power output shaft of the driver 4, driven by the driver 4 to move the moving column 5 back and forth in the frame 1, a pressure head 6 on the moving column 5, and an installation structure 7 on the moving column 5.

[0017] Specifically, when the fire door frame is coated, it needs to be transported by guide roller 2 and conveyed to the platform 1, which is located at the lower end of the spraying equipment. Then, the driver 4 drives the moving column 5 to move, which pushes the pressure head 6. The pressure head 6 pushes the fire door frame and presses it against the backing plate 3. Then, under the pressure of the pressure head 6, the positioning and pressing of the fire door frame is completed.

[0018] Please see Figure 3 and Figure 4 This utility model provides a positioning and clamping fixture for fire door processing. The installation structure 7 includes a column 71, the surface of the movable column 5 is fixed with the column 71, and the column 71 is equipped with a locking rod 72 that is laterally slidably connected.

[0019] The column 71 is slidably connected to the upper and lower parts by an insert 73. The surface of the insert 73 is provided with a groove 74, and the depths of the upper and lower ends of the groove 74 are different.

[0020] A mating sleeve 75 is fixed in the pressure head 6. A groove 76 is provided in the mating sleeve 75. A bearing 77 is fixed inside the mating sleeve 75. The groove 76 is located on the inner ring surface of the bearing 77 and is annular.

[0021] Among them, a limit ring 78 is provided on the surface of the locking rod 72 to prevent the locking rod 72 from protruding excessively.

[0022] The upper end of the insert 73 is provided with an elastic plate 79, the surface of the elastic plate 79 is provided with a locking block 710, and the inner side of the column 71 is provided with a limiting groove 711. When the elastic plate 79 is in a natural state without force, it is in an unfolded state. When the elastic plate 79 is under force, it will press against the inner side of the column 71, which improves the stability of the limiting.

[0023] Specifically, during the installation of the pressure head 6, the mating sleeve 75 is placed on the column 71. Since the slot 76 is annular, there is no need for alignment, improving the ease of installation. Then, the insertion post 73 is pushed downward, causing the sliding groove 74 to move downward. The locking rod 72 is located inside the sliding groove 74, so when the sliding groove 74 moves downward, it can push the locking rod 72 outward in the column 71 and then lock into the slot 76. Then, the locking block 710 is locked into the limiting groove 711 under the action of the elastic plate 79, thus limiting the insertion post 73 to facilitate the installation of the pressure head 6. During disassembly, the elastic plate 79 is pressed to move the locking block 710 out of the limiting groove 711, releasing the limitation on the insertion post 73. Then, the insertion post 73 is slid upward so that the sliding groove 74 does not push the locking rod 72. Then, the pressure head 6 can be removed for convenient disassembly, achieving the beneficial effect of making the disassembly and replacement of the pressure head 6 more convenient.
