Description

Technical Field

[0001] The utility model relates to the technical field of wooden door processing equipment, and particularly relates to a two-way clamping and fixing device for a door pocket hinge machine. Background Art

[0002] The wooden door pocket has a boss, which is not easy to position, clamp and is easily damaged during secondary processing. Therefore, the door pocket hinge machine has relatively high requirements for positioning and clamping functions. In the prior art, when positioning and clamping the door pocket, manual loading and unloading is usually adopted. The front end of the door pocket is flush with the front baffle of the door pocket hinge machine, the right end or the left end is flush with the side baffle of the door pocket hinge machine, and the back end is tightly pressed by manual external pushing to complete the final positioning, and then the pressing plate clamps. This requires relatively high processing technology for the operator, and at the same time, always maintain concentration to ensure accurate positioning. If the door pocket is not accurately positioned, the hole size on the finished door pocket exceeds the tolerance range, increasing the probability of defective products; in addition, two workers are required for loading, clamping and positioning of a larger-sized door pocket. Relying on manual positioning and controlling clamping is difficult to synchronize operations, and requires constant mental concentration, which is uneconomical and cannot meet the requirements of clamping and positioning door pocket boards of various size specifications.

The telescopic end of the first positioning cylinder 73 is connected to a pressing plate 74, and a pressing pad 75 mounted on the lower surface of the pressing plate 74 is connected. To ensure the stable up and down movement of the pressing plate 74, there are no less than two groups of pressing optical axes 76 that are movably matched with the pressing plate 74 and are provided on the cylinder sleeve of the first positioning cylinder 73. Additionally, to ensure that the pressing assembly 7 can be effectively and stably mounted on the guide rail 6, a locking handle 77 that cooperates with a positioning plate 5 mounted on the conveyor belt support 41 is provided on the material pressing cylinder seat 72. Referring to the attached drawings, the locking handle 77 includes a rotating handle 771 and a positioning rod 772. A plurality of positioning holes 51 that cooperate with the positioning rod 772 are provided on the positioning plate 5. By tightening the locking handle 77, the positioning rod 772 is inserted into the positioning hole 51, so that the pressing assembly 7 is fixed on the guide rail 6.

[0043] In one or more embodiments of the present utility model, the positioning assembly 10 includes a positioning slider 1001 mounted on the top of a positioning assembly seat 12. The positioning slider 1001 is movably and cooperatively connected to a positioning guide rail 1002 extending in the second direction. The upper surface of the positioning guide rail 1002 is connected to a positioning slide pillow 1003. The end of the positioning slide pillow 1003 extending towards the conveyor belt assembly 4 is provided with a positioning connecting plate 1004. The positioning connecting plate 1004 is connected to a second positioning cylinder 1006 that expands and contracts in the first direction through an end positioning seat 1005.

A positioning telescopic cylinder 1008 located on one side of the positioning slide pillow 1003 is mounted on the top of the positioning assembly seat 12 through a slide pillow cylinder seat. The telescopic end of the positioning telescopic cylinder 1008 is connected to the positioning connecting plate 1004. By the expansion and contraction of the positioning telescopic cylinder 1008, the movement of the positioning slide pillow 1003 in the second direction is controlled, and by the expansion and contraction of the second positioning cylinder 1006, the door pocket sent to the conveyor belt assembly 4 is positioned.

[0044] In one or more embodiments of the utility model, the side-pushing assembly 11 includes a side-pushing cylinder seat 111 installed on one side of the conveyor belt assembly 4, and a side-pushing telescopic cylinder 112 that can be extended and retracted along the second direction is installed on the side-pushing cylinder seat 111. The telescopic end of the side-pushing telescopic cylinder 112 passes through the side-pushing cylinder seat 111 and is connected to a side-pushing roller seat 113. Two groups of rubber pressure wheels 114 are installed on the lower surface of the side-pushing roller seat 113. The side-pushing roller seat 113 is equipped with two groups of optical axes 115 located on both sides of the side-pushing telescopic cylinder 112. The two optical axes 115 correspond to and flexibly cooperate with two linear bearings 116 installed on the side-pushing cylinder seat 111 to ensure the stability of the side-pushing direction; through the extension and retraction of the side-pushing telescopic cylinder 112, the outer circumferential side walls of the two rubber pressure wheels 114 are movably connected with the door frame, and the door frame is side-pushed to a predetermined processing position.

[0045] In one or more embodiments of the present invention, when the door cover hinge machine is loaded from the left, the diffuse reflection photoelectric sensor 9 at the right end is powered on. All cylinders are in the retracted state by default.

[0046] The first step is to realize the door frame positioning function: the door frame is conveyed from the left by the conveyor belt to the position of the diffuse reflection photoelectric sensor 9 on the right end. When the diffuse reflection photoelectric sensor 9 senses the door frame, it immediately gives an instruction to stop the operation of the conveyor belt. At this time, combined with the attached drawings, it can be seen that the 4 groups of side push components 11 are linked to push the door frame to the positioning plate 5 on the conveyor belt bracket 41 of this machine, and then the positioning component 10 on the right side is linked to push the end positioning plate 1007 to the right side of the door frame to align and complete the positioning.

[0047] First, when the conveyor belt stops, the side push telescopic cylinder 112 of the side push assembly 11 is immediately extended, and the rubber pressure wheel connected to the end of the cylinder pushes the front end of the door cover to the positioning plate 5 on the conveyor belt bracket 41 of the machine, and then the positioning telescopic cylinder 1008 of the right positioning assembly 10 is immediately extended (the extension length is adjusted in advance by the sensor according to the width of the door cover to the middle of the width of the door cover), and then the second positioning cylinder 1006 fixed on the positioning slide 1003 is extended and pushes the side of the door cover to the maximum stroke of the cylinder and keeps it still. At this point, the door cover positioning function has been realized.

[0048] The second step is to realize the door cover clamping function: after the positioning is completed, the first positioning cylinder 73 is retracted from the default extended state to return to the original position, driving the pressure plate 74 on the cylinder to press down and clamp the door cover, and the door cover clamping function is realized. In order to achieve a better clamping effect, the four groups of pressure plates 74 can be moved on the guide rail 6, and after debugging in the appropriate position, they are tightened with the locking handle 77 to prevent the pressure plate 74 assembly from lateral displacement during operation.

[0049] After the door pocket board is positioned and clamped, start the processing and general assembly 2 to process the door pocket, and thus the whole process is completed.
