Description

Technical Field

[0001] This utility model relates to the field of door frame transition frame technology, and in particular to a door frame transition frame. Background Technology

[0002] In the door frame production and assembly process, the transition jig is a key piece of equipment that connects door frame processing, transportation and subsequent assembly. Its core function is to provide temporary support for the door frame, realize position adjustment and stable transportation, and ensure the continuity and accuracy of the door frame flow between various processes.

[0003] Traditional door frame transition frames generally use the "waist-shaped groove double-panel bolt locking structure" as the core adjustment and fixing method. By setting a waist-shaped groove in the main body of the frame, the relative position of the two sides of the frame can be manually adjusted to adapt to door frames of different widths by using the cooperation of double panels and bolts.

[0004] Traditional door frame transition frames rely on manual pushing during use, which is not safe enough and can easily cause workers' hands to be squeezed between the corner pieces and the frame. In addition, traditional transition frames have poor adaptability to ultra-wide boxes, the adjustment process is cumbersome and time-consuming, and stepless adjustment cannot be achieved, making it difficult to accurately adapt to the diverse size requirements of ultra-wide box door frames. Furthermore, the transmission system of traditional door frame transition frames has great limitations and cannot adapt to width adjustment simultaneously.

[0005] Based on this, a door frame transition frame is proposed for improvement. Utility Model Content

[0006] In view of the above-mentioned existing devices, which have insufficient operational safety, are prone to causing personal injury, have poor compatibility with ultra-wide boxes, have complicated and time-consuming adjustment procedures, and have great limitations in the transmission system, which cannot synchronously adapt to width adjustment, this utility model is proposed.

[0007] To solve the above technical problems, the present invention provides the following technical solution: a door frame transition frame, including a base frame, wherein a plurality of dovetail seats are symmetrically arranged on both sides of the top of the base frame, a dovetail plate is slidably connected to the top of the dovetail seat, and the same frame is fixedly connected to the top of the dovetail plate on the same side; the base frame includes a width adjustment mechanism, a transport mechanism and a height adjustment mechanism.

[0008] Several handheld reducers are symmetrically arranged at the top center of the base frame. A handwheel is fixedly sleeved at the input end of each handheld reducer. Adjacent handheld reducers on the same side are connected by a synchronizing rod. A lead screw is fixedly sleeved at the output end of each handheld reducer. A threaded sleeve is threaded onto the surface of the lead screw. A fixing plate is symmetrically arranged on one side of the frame. The threaded sleeve is fixedly installed on the lower part of the fixing plate.

[0009] Several bearing seats are symmetrically arranged on both sides of the top of the base frame, and one end of the lead screw is rotatably connected to the inside of the bearing seat.

[0010] As a preferred embodiment, the top of the tire frame is rotatably connected to several shafts, one end of each shaft is fixedly fitted with a copper roller, and two adjacent copper rollers are connected by a first sprocket transmission assembly.

[0011] As a preferred embodiment, a motor is fixedly installed on one side of the base frame, a reducer is provided on one side of the motor, the output shaft of the motor is connected to the input end of the reducer, a transmission shaft is fixedly sleeved on the output end of the reducer, a sleeve shaft is sleeved on the surface of the transmission shaft, and one end of the sleeve shaft is connected to one of the rotating shafts through a second sprocket transmission assembly.

[0012] As a preferred embodiment, a fixing block is fitted onto the surface of the sleeve shaft, and the top end of the fixing block is fixedly connected to the bottom of the tire frame.

[0013] As a preferred embodiment, a hydraulic cylinder and a fixed seat are respectively provided on the other side of the base frame. A rotating frame is rotatably connected to the inner wall of the fixed seat. A rotating roller is rotatably connected to one end of the rotating frame. The telescopic shaft of the hydraulic cylinder is hinged to the pull rod at the other end of the rotating frame.

[0014] As a preferred embodiment, two L-shaped mounting plates are fixedly connected to one end of the top of the tire frame, and a cylinder is fixedly mounted on one end of each L-shaped mounting plate.

[0015] As a preferred embodiment, the cylinder telescopic shaft passes through the horizontal plate of the L-shaped mounting plate and is fixedly connected to a light axis slider, which is slidably connected to the top of the L-shaped mounting plate.

[0016] Compared with the prior art, the present invention has at least the following beneficial effects:

[0017] 1. This utility model can achieve stepless adjustment through the design of the width adjustment mechanism. The two sides of the tire frame can slide synchronously by simply turning the handwheel. It can quickly adapt to the size of the extra-wide box without disassembly. The hand-held reducer outputs power after reducing the speed by 1:15. At the same time, it uses its self-locking characteristics to prevent the tire frame from shifting after adjustment, which greatly optimizes production efficiency and shortens the adjustment and transportation time.

[0018] 2. This utility model achieves mechanized conveying of the door frame through a transport mechanism. With the help of a cylinder to push the optical axis slider for rapid positioning, no manual contact with the door frame or corner pieces is required throughout the process, which improves operational safety, avoids the risk of human-caused damage, and greatly improves the adaptability of production rhythm. In addition, the transport mechanism uses copper rollers 52 as ground wires, which can effectively prevent the bearings of the transport rollers on both sides from being burned out.

[0019] 3. When the door panel is topped up, uneven height can easily lead to poor flatness. By using a hydraulic cylinder to drive the rotating frame and raise and lower the rollers, the height of the door panel can be precisely adjusted to ensure that the door panel remains flat after being topped up, thus improving assembly accuracy.

[0020] 4. This utility model uses a main beam structure for the internal design of the frame, which makes the main body of the frame more robust and durable, significantly improving the overall load-bearing capacity and deformation resistance of the frame, and extending the service life of the equipment.

[0027] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0028] Reference Figures 1-4 This is the first embodiment of the present utility model, which provides a door frame transition frame, including a base frame 1. Several dovetail seats 2 are symmetrically arranged on both sides of the top of the base frame 1. A dovetail plate 21 is slidably connected to the top of the dovetail seat 2. The same frame 3 is fixedly connected to the top of the dovetail plate 21 on the same side. The base frame 1 includes a width adjustment mechanism 4, a transport mechanism 5 and a height adjustment mechanism 6.

[0029] Several handheld reducers 41 are symmetrically arranged at the top center of the base frame 1. A handwheel 42 is fixedly sleeved at the input end of the handheld reducer 41. Adjacent handheld reducers 41 on the same side are connected by a synchronizing rod 43. A lead screw 44 is fixedly sleeved at the output end of the handheld reducer 41. A threaded sleeve 46 is threaded on the surface of the lead screw 44. A fixing plate 45 is symmetrically arranged on one side of the frame 3. The threaded sleeve 46 is fixedly installed at the lower part of the fixing plate 45.

[0030] Several bearing seats 47 are symmetrically arranged on both sides of the top of the base frame 1, and one end of the lead screw 44 is rotatably connected to the inside of the bearing seat 47.

[0031] Specifically, the operator turns the handwheel 42 to transmit power to the hand-held reducer 41. Adjacent hand-held reducers 41 on the same side achieve synchronous operation through the synchronizing rod 43. The hand-held reducer 41 outputs power after reducing the speed by a ratio of 1:15, and at the same time, it uses its self-locking characteristic to prevent the adjustment of the tire frame 3 from shifting.

[0032] The handheld reducer 41 drives the lead screw 44 to rotate in the bearing seat 47. The thread on the surface of the lead screw 44 meshes with the screw sleeve 46, converting the rotational motion into the linear motion of the screw sleeve 46. The screw sleeve 46 drives the frame 3 to move through the fixed plate 45. The frame 3 drives the dovetail plate 21 to slide along the dovetail seat 2, ultimately achieving stepless adjustment of the outer width of the frame 3 on both sides.

[0033] This device can achieve stepless adjustment through the width adjustment mechanism 4. Simply turn the handwheel 42 to make the two side frames 3 slide synchronously. It can quickly adapt to the size of the ultra-wide box without disassembly. The handheld reducer 41 outputs power after reducing the speed by 1:15. At the same time, it uses its self-locking characteristic to prevent the frame 3 from shifting after adjustment, which greatly optimizes production efficiency and shortens the adjustment and transportation time.

[0034] Reference Figures 1-4 This is the second embodiment of the present utility model. The difference between this embodiment and the first embodiment is that: a number of rotating shafts 51 are rotatably connected to the top of the frame 3, and a copper roller 52 is fixedly sleeved on one end of the rotating shaft 51. Two adjacent copper rollers 52 are connected by transmission through the first sprocket transmission assembly 53.

[0035] A motor 54 is fixedly installed on one side inside the base frame 1. A reducer 55 is provided on one side of the motor 54. The output shaft of the motor 54 is connected to the input end of the reducer 55. A transmission shaft 56 is fixedly sleeved on the output end of the reducer 55. A sleeve shaft 57 is sleeved on the surface of the transmission shaft 56. One end of the sleeve shaft 57 is connected to one of the rotating shafts 51 through the second sprocket transmission assembly 59.

[0036] A fixing block 58 is fitted onto the surface of the sleeve shaft 57, and the top of the fixing block 58 is fixedly connected to the bottom of the frame 3.

[0037] Hydraulic cylinder 61 and fixed seat 62 are respectively provided on the other side of the base frame 1. Rotating frame 63 is rotatably connected to the inner wall of fixed seat 62. Rotating roller 64 is rotatably connected to one end of rotating frame 63. The telescopic shaft of hydraulic cylinder 61 is hinged to the pull rod at the other end of rotating frame 63.

[0038] Two L-shaped mounting plates 7 are fixedly connected to one end of the top of the tire frame 3, and a cylinder 71 is fixedly installed on one end of the L-shaped mounting plate 7;

[0039] The cylinder 71 telescopic shaft passes through the horizontal plate of the L-shaped mounting plate 7 and is fixedly connected to the optical axis slider 72, which is slidably connected to the top of the L-shaped mounting plate 7.

[0040] Specifically, the motor 54 starts and transmits power to the reducer 55. After being reduced in speed by the reducer 55, the power is transmitted to the drive shaft 56. The drive shaft 56 drives the sleeve shaft 57 to rotate. The sleeve shaft 57 slides along the axial direction of the drive shaft 56 as the width of the frame 3 is adjusted to ensure continuous power transmission. The sleeve shaft 57 drives one of the rotating shafts 51 to rotate through the second sprocket transmission assembly 59. The rotating shaft 51 drives the adjacent rotating shaft 51 and the copper roller 52 to rotate synchronously through the first sprocket transmission assembly 53. The door frame is placed on the copper roller 52 and rotates with the copper roller 52 to achieve smooth transition transportation.

[0041] When the door frame is transported to the preset positioning position near the end of the frame 3 by the copper roller 52 of the transport mechanism 5, the cylinder 71 drives the telescopic shaft to extend. The telescopic shaft drives the optical axis slider 72 to slide away from the cylinder 71 along the top of the L-shaped mounting plate 7. When the optical axis slider 72 reaches the preset position, its end away from the cylinder 71 directly contacts the end of the door frame, blocking the door frame and restricting the door frame from continuing to move, thus achieving precise positioning and stopping of the door frame.

[0042] When the door panel height needs to be raised to ensure flatness, the hydraulic cylinder 61 is activated, and its telescopic shaft extends outward, applying a thrust to the pull rod at the other end of the rotating frame 63. Since the rotating frame 63 uses the fixed seat 62 as a fulcrum, it rotates upward around the fixed seat 62 under the action of the thrust, driving the rotating roller 64 at one end to rise synchronously. The rotating roller 64 contacts the bottom of the door panel and lifts the door panel until the door panel reaches the preset flat height. When the door panel height needs to be lowered, the telescopic shaft of the hydraulic cylinder 61 retracts, the thrust on the pull rod of the rotating frame 63 decreases or disappears, and the rotating frame 63 rotates downward around the fixed seat 62 under the action of the door panel's gravity or its own restoring force. The rotating roller 64 descends with the rotating frame 63, and the door panel height decreases accordingly until it is adjusted to the target position.

[0043] After being adjusted to the target height, the telescopic shaft can maintain a fixed length, so that the rotating frame 63 and the rotating roller 64 maintain the current support state, ensuring that the door panel always remains flat in subsequent operations and avoiding production errors caused by height deviation.

[0044] This device achieves mechanized conveying of the door frame through the transport mechanism 5, and works with the cylinder 71 to push the optical axis slider 72 for rapid positioning. The entire process does not require manual contact with the door frame or corner pieces, which improves operational safety, avoids the risk of human-caused damage, and greatly improves the adaptability of production rhythm. In addition, the transport mechanism 5 uses copper rollers 52 as ground wires, which can effectively prevent the bearings of the transport rollers on both sides from being burned out. The hydraulic cylinder 61 drives the rotating frame 63 to drive the rotating roller 64 to rise and fall, which can precisely adjust the height of the door panel and ensure that the door panel remains flat after it is topped up, thus improving assembly accuracy.

[0045] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
