[0030] In order to more clearly understand the technical means of the present invention and implement it according to the contents of the specification, the specific implementation methods of the present invention are further described in detail below in conjunction with the drawings and examples. The following examples are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0031] A high-precision semi-automatic assembly, lamination and pressure-maintaining fixture comprises: a support platform 1; a first material tooling 2 located at the material discharge position of the support platform 1, wherein the first material tooling 2 is used for positioning and fixing static assembly materials.

[0032] The first material tooling 2 includes: a mounting block 21 embedded in the support platform 1; a static material placement platform 22 fixedly connected to the mounting block 21 for placing static assembly materials, and a plurality of positioning blocks protruding from the static material placement platform 22 for positioning; a plurality of suction nozzles 23 opened on the static material placement platform 22; and a first vacuum adsorption device 24 arranged under the support platform 1 and connected to the suction nozzles 23.

[0033] After the static assembly parts are placed on the static part placement table 22, the static parts can be preliminarily positioned by their shape, and then the static parts can be adsorbed and fixed on the static part placement table 22 by the first vacuum adsorption device 24 in cooperation with the suction nozzle 23. The adsorption fixation method can make the parts be fixed while remaining motionless, avoiding position deviation during fixation.

[0034] A side pressure mechanism 3 capable of performing side pressure maintenance on a statically assembled material placed on a first material fixture 2; the side pressure mechanism 3 includes: a first slide rail 31 fixed on the support platform 1 and close to the first material fixture 2; a first slider 32 slidably connected to the first slide rail 31 and capable of reciprocating toward the first material fixture 2; and a side pressure head 33 provided on the first slider 32 and facing the first material fixture 2.

[0035] When a force is applied, the first slide block 32 can slide on the first slide rail 31 , so that the side pressure head 33 can contact the static assembly part placed on the first part tooling 2 , and the side edge thereof can be pressed.

[0036] The side pressure mechanism 3 also includes: a second slide rail 34 arranged on the support platform 1 and parallel to the first slide rail 31; a second slider 35 slidably connected to the second slide rail 34; a pushing portion 36 fixed to the second slider 35 for easy handholding; and a resistance rod 37 arranged inside the first slider 32 and with one end exposed to the resistance connecting block, the resistance rod 37 is slidably connected to the first slider 32, and the other end of the resistance rod 37 is connected to the first slider 32 through a spring.

[0037] After the dynamic assembly parts and the static assembly parts are spliced, the operator can hold the pushing part 36 and apply a certain pressure to make the second slider 35 move on the second slide rail 34, and the pushing part 36 can move smoothly. When the pushing part 36 moves, it will squeeze the resistance rod 37, and the resistance rod 37 will drive the first slider 32 to move on the first slide rail 31 through the spring, so that the side pressure head 33 squeezes the side of the material to achieve the purpose of side pressure maintenance, and the applied force can be buffered by the spring to avoid damage to the material.

[0038] A second material fixture 4 for positioning and fixing dynamic assembly parts is mounted on the support table 1. The second material fixture 4 can drive the dynamic assembly parts to flip after being positioned and fixed, and the flipped dynamic assembly parts can be spliced ​​and assembled with the static assembly parts fixed on the first material fixture 2. The second material fixture 4 includes: a fixed seat 41 fixed on the support table 1; a mounting table 42 rotatably connected to the fixed seat 41 through a hinge shaft; a dynamic material placement table 43 provided on the mounting table 42 for positioning the dynamic assembly parts; a pressure-maintaining adsorption component that can reciprocate in the vertical direction and penetrate the dynamic material placement table 43; and a control component that drives the pressure-maintaining adsorption component to move.

[0039] After the dynamic assembly parts are placed on the dynamic assembly part placement table 43, the dynamic assembly parts can be adsorbed and fixed by the pressure-maintaining adsorption component, and then the mounting table 42 is manually flipped over to make it rotate with the fixed seat 41 as the center. The flipped mounting table 42 can make the dynamic assembly parts cover the fixed static assembly parts, so as to achieve the fitting and splicing of the dynamic assembly parts and the static assembly parts. Then, the movement of the pressure-maintaining adsorption component can be achieved through the control component. When the mounting table 42 is fixed, the movable pressure-maintaining adsorption component can apply pressure to achieve pressure maintenance after the parts are assembled.

[0040] The assembly of static assembly parts and dynamic assembly parts is realized by flipping, which can improve the accuracy of fitting assembly. During the fitting process, the parts will not be shifted in position, which further improves the splicing accuracy. The operation is simple and the material unloading is convenient after the assembly is completed.

[0041] A fixing mechanism 5 is arranged on the support table 1 and can fix the flipped second material tooling 4; the fixing mechanism 5 includes: a transmission frame 51 vertically embedded in the support table 1; a sheet metal part 52 arranged inside the transmission frame 51 and capable of reciprocating in the vertical direction, and a fixed pressure head 53 extending from the top of the sheet metal part 52 can expose the transmission frame 51, and the fixing mechanism 5 also includes: an arcuate groove 54 opened on the sheet metal part 52; a fixing column 55 fixed inside the transmission frame 51 and slidably connected to the arcuate groove 54, and the sheet metal part 52 can make the fixed pressure head 53 expose the transmission frame 51 while descending through the fixing column 55 and the arcuate groove 54; and a small cylinder 56 vertically arranged at the bottom of the transmission frame 51 and the output end of which is movably connected to the sheet metal part 52.

[0042] When the mounting table 42 is flipped over, the small cylinder 56 can be used to drive the sheet metal part 52 to descend. When the sheet metal part 52 descends, the fixed column 55 is located inside the arc groove 54, so that the shape of the arc groove 54 changes during descent, so that the fixed pressure head 53 on the top of the sheet metal part 52 is exposed to the inside of the transmission frame 51 during descent. The fixed pressure head 53 that is pressed down and exposed can fix the flipped mounting table 42. After fixation, the assembled parts can be pressure-maintained by the pressure-maintaining adsorption component.

[0043] And a pressing mechanism 6 vertically arranged on the support platform 1, which can maintain the pressure of the assembled parts and statically assembled parts, the pressing mechanism 6 includes: a support plate 61 vertically arranged on the support platform 1; a fixed plate 62 arranged on the support plate 61 and reciprocating along its vertical direction; a counterweight frame 63 arranged on the fixed plate 62; a pressing head 64 arranged at the bottom of the counterweight frame 63 and facing the first material tooling 2; a connecting part 65 fixed on the fixed plate 62; a counterweight block 66 detachably arranged on the counterweight frame 63; and a hydraulic cylinder 67 vertically arranged on the support plate 61 and the output end of which is fixedly connected to the connecting part.

[0044] When working, the hydraulic cylinder 67 can drive the fixed plate 62 to rise and fall through the connecting part 65. When the fixed plate 62 descends, the counterweight frame 63 will drive the pressure head 64 to descend. The descent of the pressure head 64 can realize the pressure maintenance of the static assembly parts before assembly and the pressure maintenance of the parts after assembly.

[0045] The use of the counterweight block 66 can achieve the purpose of maintaining pressure by its own weight when the hydraulic cylinder 67 stops working or reaches a predetermined position.

[0046] Furthermore, the pressure-maintaining adsorption assembly includes: a pressure-maintaining column 44 that reciprocates in the vertical direction and penetrates the moving material placement table 43; a vacuum air hole that penetrates the pressure-maintaining column 44; and a second vacuum adsorption device 45 that is arranged on the pressure-maintaining column 44 and connected to the vacuum air hole.

[0047] When the moving assembly parts are placed on the moving assembly placement table 43, the second vacuum adsorption device 45 can use the vacuum air holes to enable the pressure-maintaining column 44 to adsorb and fix the moving assembly parts. Since the pressure-maintaining column 44 is raised and lowered, the adsorbed moving assembly parts can be driven to rise and fall, which is convenient for subsequent pressure maintenance.

[0048] Furthermore, the control component includes: a connecting frame 46 vertically fixed on the mounting platform 42; a driving cylinder 47 arranged on the connecting frame 46 along the vertical direction; and a transmission member 48 arranged on the output shaft of the driving cylinder 47 and fixed to the pressure-maintaining adsorption component, and the transmission member 48 is connected to the output shaft of the driving cylinder 47 through a buffer spring 49.

[0049] When working, the driving cylinder 47 can drive the pressure-maintaining column 44 to rise and fall through the transmission member 48. Since a buffer spring 49 is provided between the transmission member 48 and the driving cylinder 47, the buffer spring 49 can provide buffering when the pressure-maintaining column 44 is maintaining pressure to avoid damage to the material.

[0050] Furthermore, a positioning seat 57 is provided on the mounting platform 42 , a positioning groove 58 is formed on the positioning seat 57 , and a positioning protrusion 59 that can be matched with the positioning groove 58 is provided on the transmission frame 51 .

[0051] When the mounting platform 42 is turned over, the positioning groove 58 on the positioning seat 57 will engage with the positioning protrusion 59 , and the fixed pressing head 53 will press on the positioning seat 57 when pressing down.

[0052] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the technical principles of the present invention, and these improvements and modifications should also be regarded as within the scope of protection of the present invention.
