Description

Technical Field

[0001] The utility model relates to the technical field of elevator production, in particular to an adjustable assembly fixture. Background Art

[0002] Elevator door panels refer to the door panels of elevator hall doors, which are key components of elevator exterior design and elevator safety protection. Its main function is to separate the elevator door from the elevator hall to prevent people from entering or exiting by mistake. In order to smoothly install the elevator door panels so that the elevator can operate normally, during the production process of the elevator door panels, it is necessary to open assembly holes and other processing operations on the elevator door panels, which is also convenient for installing door locks, door handles, sensors and other equipment on the elevator door panels.

[0003] When drilling holes in elevator door panels, workers need to use clamping jigs to fix the door panels to ensure the accuracy of processing. At present, the spacing between the clamping plates of some clamping jigs on the market is relatively fixed and cannot be adjusted, which means that the jig can only clamp door panels of specific sizes and shapes. Its scope of application is relatively limited. When door panels of different sizes need to be processed, the jig needs to be replaced, which affects the processing efficiency and cost of the total door panel production line.

[0004] Therefore, in order to solve the above problems, an adjustable assembly fixture is proposed. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides an adjustable assembly fixture, which has the advantages of adjustable clamping plate spacing, etc., and solves the problem that the application scope of traditional clamping fixtures is relatively limited.

[0006] To achieve the above purpose, the utility model provides the following technical solutions: an adjustable assembly jig includes an infeed conveyor belt, a base and an outfeed conveyor belt, wherein the infeed conveyor belt, the base and the outfeed conveyor belt are arranged in a "one" shape in sequence along the transverse direction of the base;

[0007] The upper surface of the base is provided with a frame, and the lower surface of the frame top plate is provided with a clamping assembly and a lifting assembly spaced along the longitudinal direction of the base, and the clamping assembly is installed at the center of the lower surface of the frame top plate;

[0008] Wherein, the clamping assembly includes two mounting plates, the two mounting plates are respectively mounted on the lower surface of the frame top plate at the opposite edges on the longitudinal direction of the base, the two mounting plates are respectively mounted on the opposite surfaces thereof, a reciprocating motor and a bearing seat are respectively mounted, a forward and reverse screw is rotatably connected between the reciprocating motor and the bearing seat, a first slider and a second slider are respectively meshed and slidably engaged on the threads on both sides of the forward and reverse screw, and clamping plates are respectively mounted on the lower surfaces of the first slider and the second slider;

[0009] Among them, the lifting assembly includes a cylinder, which is installed on the edge of the lower surface of the frame top plate close to the side of the discharge conveyor belt. The cylinder output shaft is arranged downward and a baffle is installed at the bottom end. The baffle is installed along the longitudinal direction of the base between two adjacent support legs of the frame along the longitudinal direction.

[0010] Furthermore, the first sliding block and the second sliding block are symmetrically distributed on the left and right sides of the outer surface of the forward and reverse screws at the center of the forward and reverse screws.

[0011] Furthermore, one end of the forward and reverse screw is connected to the tail end of the output shaft of the reciprocating motor, and the outer wall of the other end of the forward and reverse screw is connected to the inner wall of the inner ring of the bearing inside the bearing seat.

[0012] Furthermore, two limit rods are installed between the two mounting plates and are located on both sides of the forward and reverse screw rods. The two limit rods both pass through the first slider and the second slider, and the first slider and the second slider are slidably connected to the two limit rods.

[0015] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0016] 1. The adjustable assembly jig utilizes a clamping component installed at the bottom of the frame top plate. By controlling the operation of the reciprocating motor, the forward and reverse screws can be driven to rotate clockwise and counterclockwise, so that the distance between the two clamping plates can be adjusted to clamp door panels of different sizes, thereby increasing the application scope of the jig, avoiding the limitation of the relatively fixed clamping size of traditional jigs, and improving the overall production efficiency of door panel processing.

[0017] 2. The adjustable assembly fixture, with the cooperation of the clamping component and the lifting component, can keep the fixed position of door panels of the same size on the base consistent, which helps to ensure the consistency and accuracy of the processing of door panels of the same size and improve the overall quality of door panel processing.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-3 In this embodiment, an adjustable assembly jig is provided, which utilizes a clamping assembly 3 installed at the bottom of the top plate of the frame 2. By controlling the operation of the reciprocating motor 32, the forward and reverse screws 34 can be driven to rotate clockwise and counterclockwise, so that the spacing between the two clamping plates 38 can be adjusted to clamp door panels of different sizes, thereby increasing the applicable scope of the jig and avoiding the limitation of the relatively fixed clamping size of the traditional jig; at the same time, with the cooperation of the lifting assembly 4, the fixed position of the door panels of the same size on the base 1 can be kept consistent. This design helps to ensure the consistency and accuracy of door panel processing and improve the overall production efficiency of door panel processing.

[0024] Specifically, an adjustable assembly jig in this embodiment includes an infeed conveyor belt 11, a base 1 and an outfeed conveyor belt 12, wherein the infeed conveyor belt 11, the base 1 and the outfeed conveyor belt 12 are arranged adjacent to each other in a "one" shape in the transverse direction of the base 1;

[0025] A frame 2 is installed on the upper surface of the base 1, and a clamping assembly 3 and a lifting assembly 4 are installed on the lower surface of the top plate of the frame 2 at intervals along the longitudinal direction of the base 1. The clamping assembly 3 is installed at the center of the lower surface of the top plate of the frame 2;

[0026] The clamping assembly 3 includes two mounting plates 31, which are respectively mounted on the lower surface of the top plate of the frame 2 at the longitudinally opposite edges of the base 1, and the reciprocating motor 32 and the bearing seat 33 are respectively mounted on the opposite surfaces of the two mounting plates 31. A forward and reverse screw 34 is rotatably connected between the reciprocating motor 32 and the bearing seat 33. The threads on both sides of the forward and reverse screw 34 are respectively meshed and slid with a first slider 35 and a second slider 36, and the lower surfaces of the first slider 35 and the second slider 36 are both mounted with a clamping plate 38;

[0027] Among them, the lifting assembly 4 includes a cylinder 41, which is installed on the edge of the lower surface of the top plate of the frame 2 close to the side of the discharge conveyor belt 12. The output shaft of the cylinder 41 is arranged downward and a baffle 42 is installed at the bottom end. The baffle 42 is installed along the longitudinal direction of the base 1 between two adjacent support legs of the frame 2 along the longitudinal direction.

[0028] During actual use, the elevator door panel can be moved to the base 1 under the transmission of the feed conveyor belt 11; then the staff controls the operation of the cylinder 41, and the output shaft of the cylinder 41 can drive the baffle 42 to perform reciprocating movements; the staff controls the output shaft of the cylinder 41 to push the baffle 42 down, so that the bottom of the baffle 42 fits with the upper surface of the base 1, and then the staff pushes the door panel so that the opposite surface of the door panel and the baffle 42 fits, thereby, the same size of door panels can be fixed on the base 1 at the same horizontal position, which helps to ensure the consistency and accuracy of the door panel processing; the staff then controls the reciprocating motor 32 is running, the reciprocating motor 32 can drive the forward and reverse screws 34 to rotate clockwise and counterclockwise, so that the first slider 35 and the second slider 36 can respectively drive the two clamping plates 38 to move in opposite directions and back directions on the forward and reverse screws 34, thereby making the distance between the two clamping plates 38 adjustable to suit door panels of different sizes; the staff controls the reciprocating motor 32 to adjust the distance between the two clamping plates 38, and fixes the door panel on the base 1 to prevent the staff from shaking the door panel under the impact of the punching machine during the subsequent punching process of the door panel, thereby affecting the accuracy of the punching of the door panel. When the staff completes the processing of the door panel, they control the cylinder 41 to drive the baffle 42 to rise, and the staff pushes the door panel onto the discharge conveyor belt 12 again, and performs subsequent operations on the door panel under the transmission of the discharge conveyor belt 12.

[0029] The first slider 35 and the second slider 36 are symmetrically distributed on the left and right sides of the outer surface of the forward and reverse screw rods 34 at the center of the forward and reverse screw rods 34 .

[0030] The first slider 35 and the second slider 36 are symmetrically distributed on the forward and reverse screws 34. When the forward and reverse screws 34 rotate, the first slider 35 and the second slider 36 move toward and away from each other along the center of the forward and reverse screws 34, so that when the two clamps 38 clamp the door panels, the door panels of the same size can be kept in the same longitudinal position fixed on the base 1. With the joint action of the baffle, the door panels of the same size can be kept in the same fixed position on the base 1, which helps to ensure the consistency and accuracy of the door panel processing and improve the overall production efficiency of the door panel processing.

[0031] One end of the forward and reverse screw rod 34 is connected to the tail end of the output shaft of the reciprocating motor 32 , and the outer wall of the other end of the forward and reverse screw rod 34 is connected to the inner wall of the inner ring of the bearing inside the bearing seat 33 .

[0032] The operation of the reciprocating motor 32 can drive its output shaft to rotate clockwise and counterclockwise. With the cooperation of the bearing inside the bearing seat 33, the forward and reverse screws 34 can rotate clockwise and counterclockwise between the reciprocating motor 32 and the bearing seat 33.

[0033] Two limiting rods 37 are installed between the two mounting plates 31 and are located on both sides of the forward and reverse screw rods 34 . The two limiting rods 37 both penetrate the first slider 35 and the second slider 36 . The first slider 35 and the second slider 36 are slidably connected to the two limiting rods 37 .

[0034] Under the restriction of the limiting rod 37 , when the forward and reverse screw rods 34 rotate to drive the first slider 35 and the second slider 36 to move, the first slider 35 and the second slider 36 can be prevented from rotating and damaging the two clamping plates 38 .

[0035] Two slide grooves 43 are installed on the opposite surfaces of the two supporting legs at the lower end of the top plate of the frame 2 close to the discharge conveyor belt 12, and the baffle 42 is respectively embedded in the two slide grooves 43 at the opposite ends along the longitudinal direction of the base 1, and the baffle 42 is slidably connected to the two slide grooves 43 through the cylinder 41.

[0036] Under the constraint of the slide groove 43 , the consistency of the movement trajectory of the baffle 42 during the lifting process can be ensured, avoiding the baffle 42 from shaking or deflecting during the lifting process, and further ensuring the consistency of the horizontal position of the door panel fixed on the base 1 .

[0037] At least one pulley 5 is installed on the upper surface of the base 1 to make it more convenient for the staff to push the door panel horizontally on the base 1.

[0038] The working principle of the above embodiment is:

[0039] The elevator door panel can be moved to the base 1 under the transmission of the feeding conveyor belt 11; then the staff controls the output shaft of the cylinder 41 to push the baffle 42 down, so that the bottom of the baffle 42 fits with the upper surface of the base 1, and the staff pushes the door panel so that the opposite surface of the door panel and the baffle 42 fits, thereby, the door panels of the same size can be kept in the same horizontal position fixed on the base 1, which helps to ensure the consistency and accuracy of the door panel processing; the staff then controls the operation of the reciprocating motor 32, and the operation of the reciprocating motor 32 can drive the forward and reverse screws 34 to rotate clockwise and counterclockwise, thereby making the first slider 35 and the second slider 36 move in opposite and reverse directions with the center of the forward and reverse screws 34 as the center. The staff controls the operation of the reciprocating motor 32 to adjust the distance between the two clamping plates 38, and fix the door panel on the base 1 to prevent the staff from shaking under the impact of the punching machine during the subsequent punching of the door panel, thereby affecting the accuracy of the door panel punching. When the staff has finished processing the door panel, the cylinder 41 is controlled to operate to drive the baffle 42 to rise, and the staff pushes the door panel onto the discharge conveyor belt 12 again, and performs subsequent operations on the door panel under the transmission of the discharge conveyor belt 12.
