Description

Technical Field

[0001] This utility model relates to the field of needle processing technology, specifically to a needle assembly fixture. Background Technology

[0002] A needle generally refers to a component that allows fluid to flow out precisely, such as a dispensing machine needle. The dispensing machine needle is installed at the top of the syringe of the dispensing machine, and its main function is to precisely control the amount and position of glue dispensed.

[0003] A needle typically consists of a needle hub and a needle tip, with the tip being a thin tubular structure. During needle assembly, a clamp is needed to hold the needle hub in place before inserting the needle tip. Current clamps usually only hold a single needle hub, leading to reduced efficiency during needle assembly. Therefore, there is an urgent need to design a needle assembly clamp to solve these problems. Utility Model Content

[0004] The purpose of this invention is to provide a needle assembly fixture to address the aforementioned shortcomings in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A needle assembly fixture includes a support plate. Evenly distributed fixed blocks are fixed to the top outer wall of the support plate. A movable block is provided on one side of each fixed block. Positioning grooves are provided on the side walls of the fixed blocks and movable blocks that are close to each other. A needle seat is provided inside each positioning groove. Two support plates are fixed to the top outer wall of the support plate. A screw is connected to the two support plates by a bearing. A slider is fixed to one side outer wall of the movable block. A nut is fixed to one side outer wall of the slider. The nut is threadedly connected to the screw. A rotating mechanism is provided at one end of the screw.

[0007] Furthermore, the rotating mechanism includes a mounting shell fixed to the top of the support plate, one end of the screw extending into the interior of the mounting shell where a worm gear is fixed, and a worm connected to an internal bearing of the mounting shell, the worm gear meshing with the worm gear.

[0008] Furthermore, a handwheel is rotatably connected to the outer wall of the mounting housing, and the output shaft of the handwheel is connected to a worm gear key.

[0009] Furthermore, a slide rail is fixed between the two support plates, and the slider is slidably connected to the slide rail.

[0010] Furthermore, a mounting plate is fixed to the bottom of the support plate, and mounting holes are opened on the top outer wall of the mounting plate.

[0011] Furthermore, an oil inlet is welded to one side of the outer wall of the mounting housing, and a sealing cap is threaded to one end of the oil inlet.

[0012] In the above technical solution, the needle assembly fixture provided by this utility model has the following advantages: the rotation of the screw can drive multiple moving blocks to move, thereby enabling the fixture to fix multiple needle seats at one time, which facilitates the simultaneous assembly of multiple needles and improves the assembly efficiency of the needles; the worm gear drives the worm wheel to rotate, which in turn drives the screw to rotate. The self-locking effect of the worm gear and the worm wheel can prevent the needle seats from loosening, making the needle seats more stable when fixed. Attached Figure Description

[0019] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0020] like Figure 1-3 As shown, the needle assembly fixture provided in this embodiment of the present invention includes a support plate 1. The top outer wall of the support plate 1 is fixed with uniformly distributed fixed blocks 2. A movable block 3 is provided on one side of the fixed blocks 2. The side walls of the fixed blocks 2 and the movable blocks 3 that are close to each other are provided with positioning grooves 12. A needle seat 4 is provided inside the positioning groove 12. Two support plates 9 are fixed on the top outer wall of the support plate 1. A screw 5 is connected between the two support plates 9 by a bearing. A slider 6 is fixed on one side outer wall of the movable block 3. A nut 7 is fixed on one side outer wall of the slider 6. The nut 7 is threadedly connected to the screw 5. A rotating mechanism is provided at one end of the screw 5.

[0021] Specifically, in this embodiment, a support plate 1 is included. The top outer wall of the support plate 1 is fixed with evenly distributed fixed blocks 2. A movable block 3 is provided on one side of the fixed blocks 2. There are multiple fixed blocks 2 and movable blocks 3. The side walls of the fixed blocks 2 and movable blocks 3 that are close to each other are provided with positioning grooves 12. The positioning grooves 12 are "V" shaped. A needle seat 4 is provided inside the positioning groove 12. When in use, the needle seat 4 is fixed between the fixed blocks 2 and the movable blocks 3. Two support plates 9 are fixed on the top outer wall of the support plate 1. A screw 5 is connected between the two support plates 9 by a bearing. A slider 6 is fixed on one side outer wall of the movable block 3. A nut 7 is fixed on one side outer wall of the slider 6. The nut 7 is threadedly connected to the screw 5. When the screw 5 rotates, it can drive the slider 6 to move. A rotating mechanism is provided at one end of the screw 5. The rotating mechanism is used to rotate the screw 5.

[0022] The needle assembly fixture provided by this utility model can drive multiple moving blocks 3 to move by rotating the screw 5, thereby enabling the fixture to fix multiple needle seats 4 at one time, which facilitates the simultaneous assembly of multiple needles and improves the assembly efficiency of needles.

[0023] In another embodiment of this utility model, the rotating mechanism includes a mounting shell 13 fixed to the top of the support plate 1. One end of the screw 5 extends into the interior of the mounting shell 13 and is fixed with a worm gear 15. A worm 14 is connected to the bearing inside the mounting shell 13. The worm 14 meshes with the worm gear 15, and the worm 14 drives the worm gear 15 to rotate, which in turn drives the screw 5 to rotate. The self-locking effect of the worm 14 and the worm gear 15 can prevent the needle seat 4 from loosening, making the needle seat 4 more stable when fixed. A handwheel 16 is rotatably connected to the outer wall of the mounting shell 13. The output shaft of the handwheel 16 is keyed to the worm 14, and the handwheel 16 allows the worm 14 to be rotated by hand. An oil inlet 17 is welded to one side of the outer wall of the mounting shell 13, which facilitates the injection of lubricating oil into the interior of the mounting shell 13, thereby reducing the wear when the worm 14 and the worm gear 15 mesh and transmit power. A sealing cap 18 is threaded to one end of the oil inlet 17.

[0024] In another embodiment of this utility model, a slide rail 8 is fixed between the two support plates 9, and the slider 6 is slidably connected to the slide rail 8. By sliding the slider 6 to the slide rail 8, the moving block 3 is more stable when it moves. A mounting plate 10 is fixed to the bottom of the support plate 1. A mounting hole 11 is opened on the top outer wall of the mounting plate 10. The mounting hole 11 is an open hole, which makes it easy to fix the mounting plate 10 with bolts.

[0025] Working principle: When it is necessary to fix the needle holder 4, first place the needle holder 4 between the fixed block 2 and the moving block 3, and then rotate the worm 14 by the handwheel 16, so that the worm 14 drives the worm wheel 15 and the screw 5 to rotate. The rotation of the screw 5 drives the slider 6 and the moving block 3 to move, thereby fixing the needle holder 4 with the clamp.

[0026] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
