Description

Technical Field

[0001] This utility model belongs to the field of needle processing technology, specifically a needle clamping and positioning device before grinding. Background Technology

[0002] Currently, in the field of medical device manufacturing, needles are the core components of medical consumables such as syringes and infusion sets. Their surface finish and dimensional accuracy directly affect the safety of use and patient comfort. Needles often need to undergo external surface polishing during the production process to remove burrs and improve surface quality.

[0003] However, existing needle clamping and positioning devices still have the following prominent problems in practical applications:

[0004] (1) Low clamping efficiency and difficulty in achieving synchronous positioning of multiple needle tubes: Traditional clamping methods cannot meet the needs of batch grinding. Operators need to repeatedly adjust the position of each needle tube, which is not only inefficient, but also prone to uneven clamping force, causing the needle tubes to deviate or loosen during the grinding process, affecting the consistency of grinding and processing quality.

[0005] (2) Lack of polishing fluid spraying structure: Most existing equipment does not integrate cooling and chip removal functions. During the polishing process, frictional heat can easily cause local overheating of the needle surface, leading to micro-cracks or material deformation. At the same time, if the polishing debris is not removed in time, it will scratch the needle surface, reduce product yield, cause uneven spraying, and make operation cumbersome.

[0006] To address this, we provide a needle clamping and positioning device before grinding. Utility Model Content

[0007] To overcome the shortcomings of existing technologies, solve the problems of synchronous clamping and positioning of multiple needle tubes, reduce friction temperature during polishing, and reduce scratches on the needle tube surface, a needle tube clamping and positioning device before polishing is proposed.

[0008] The technical solution adopted by this utility model to solve its technical problem is:

[0009] The needle tube clamping and positioning device before grinding includes:

[0010] The base has mounting plates fixedly installed on both sides, and fixing bolts are provided inside the mounting plates. The upper end of the base has multiple needle tube grooves, and a first anti-slip pad is provided inside the needle tube grooves.

[0011] A synchronous clamping and positioning assembly is disposed in the middle of both sides of the base and is used to synchronously clamp and position the needle tube before grinding.

[0012] The synchronous clamping and positioning component includes:

[0013] The frame is bolted to the middle of both sides of the base. The frame has travel grooves on both sides and a groove on the inner top. The motor housing is bolted to the upper end of the frame.

[0014] Preferably, the synchronous clamping and positioning component further includes:

[0015] A motor is fixedly installed inside the motor housing. A rotating rod is splined to the output end of the motor. A first sprocket is fixedly installed at one end of the rotating rod, and a chain is engaged on the surface of the first sprocket.

[0016] Preferably, a second sprocket is engaged with the inner sidewall of the chain, the upper end of the second sprocket is disposed in a groove via a bearing, and a transmission rod is fixedly installed on the lower ends of the second sprocket and the first sprocket.

[0017] Preferably, a lead screw is fixedly installed at one end of the transmission rod, and one end of the lead screw is disposed in the stroke groove through a bearing.

[0018] Preferably, the surface of the lead screw is threadedly connected to a threaded block through a threaded hole, the threaded block is partially adapted to the stroke groove, and a clamping plate is fixedly installed on one side of the threaded block.

[0019] Preferably, the lower end of the clamping plate is provided with a plurality of upper needle tube grooves, and the upper needle tube grooves correspond to the lower needle tube grooves. A second anti-slip pad is provided inside the upper needle tube groove.

[0020] Preferably, it further includes:

[0021] A polishing fluid spraying assembly is disposed at the upper end of the clamping plate and is used to spray polishing fluid onto the polishing needle.

[0022] The polishing fluid spraying assembly includes:

[0023] A pump plate is bolted to the upper end of the clamping plate, and a liquid pump is fixedly installed on the upper end of the pump plate. A first delivery pipe is connected to the back of the liquid pump, and a second delivery pipe is connected to the front of the liquid pump.

[0024] Preferably, one end of the second delivery pipe is connected to a hollow plate, and both sides of the hollow plate are bolted to one side of the upper end of the clamping plate. Multiple spray heads are connected to the front of the hollow plate.

[0025] The beneficial effects of this utility model are:

[0026] The synchronous clamping and positioning assembly of this utility model places multiple needle tubes into the lower needle tube slot. An external power supply to the motor drives a rotating rod and a first sprocket to rotate synchronously. The first sprocket then drives a chain and a second sprocket to rotate synchronously. The second sprocket, in turn, drives a transmission rod to rotate synchronously with the first sprocket. This transmission rod then drives a lead screw to rotate, which in turn drives a threaded block to move stably within a travel groove. The threaded block then drives a clamping plate to move synchronously with the upper needle tube slot, clamping and positioning the needle tubes. The reverse operation removes the restriction on the needle tubes, thus achieving synchronous clamping and positioning of multiple needle tubes, improving clamping stability, preventing displacement and skewing during grinding, and improving grinding quality.

[0027] The polishing fluid spraying assembly of this utility model, when the needle tube is clamped and polished, delivers polishing fluid to the second delivery pipe through a pump and a first delivery pipe, then to the hollow plate through the second delivery pipe, and finally to the spray head through the hollow plate. The polishing fluid is then sprayed onto the needle tube through the spray head, thereby reducing the friction temperature during the polishing process, reducing scratches on the needle tube surface, washing away polishing debris, and improving the polishing smoothness and processing quality of the needle tube.

[0041] The base 1 has mounting plates 2 fixedly installed on both sides. The mounting plates 2 have fixing bolts inside. The upper end of the base 1 has multiple needle tube grooves 3. The needle tube grooves 3 have first anti-slip pads 4 inside. The synchronous clamping and positioning components 5 are set in the middle of both sides of the base 1 for synchronously clamping and positioning the needle tubes before polishing. The polishing fluid spraying component 6 is set in the upper end of the clamping plate 513 for spraying polishing fluid onto the needle tubes to be polished.

[0042] In this embodiment, the synchronous clamping and positioning component 5 is first used to achieve synchronous clamping and positioning of multiple needle tubes, thereby improving clamping stability, avoiding displacement and skewing during the grinding process, and improving grinding quality. Then, the grinding fluid spraying component 6 is used to reduce the friction temperature during the grinding process, reduce scratches on the needle tube surface, and wash away grinding debris, thereby improving the grinding smoothness and processing quality of the needle tubes.

[0043] Example 2:

[0044] Based on Embodiment 1, a synchronous clamping and positioning component 5 is further disclosed.

[0045] like Figure 1 , Figure 2 and Figure 3 As shown, the synchronous clamping and positioning component 5 includes:

[0046] The frame 501 is bolted to the middle of both sides of the base 1. The frame 501 has a stroke groove 502 on both sides and a groove on the top inner side. The motor housing 503 is bolted to the upper end of the frame 501.

[0047] The synchronous clamping and positioning component 5 also includes:

[0048] A motor 504 is fixedly installed inside the motor housing 503. A rotating rod 505 is splinedly connected to the output end of the motor 504. A first sprocket 506 is fixedly installed at one end of the rotating rod 505. A chain 507 meshes with the surface of the first sprocket 506. A second sprocket 508 meshes with the inner wall of the chain 507. The upper end of the second sprocket 508 is set in a groove via a bearing. A transmission rod 509 is fixedly installed at the lower ends of the second sprocket 508 and the first sprocket 506. One end of the transmission rod 509... A lead screw 510 is fixedly installed. One end of the lead screw 510 is set in the stroke groove 502 through a bearing. A threaded block 512 is threadedly connected to the surface of the lead screw 510 through a threaded hole 511. The threaded block 512 is partially adapted to the stroke groove 502. A clamping plate 513 is fixedly installed on one side of the threaded block 512.

A second anti-slip pad is provided inside the upper needle tube grooves 514.

[0049] In this embodiment, multiple needle tubes are placed in the lower needle tube slot 3. The motor 504, powered by an external power source, drives the rotating rod 505 and the first sprocket 506 to rotate synchronously. The first sprocket 506 then drives the chain 507 and the second sprocket 508 to rotate synchronously. The second sprocket 508, in sync with the first sprocket 506, drives the transmission rod 509 to rotate. The transmission rod 509 then drives the lead screw 510 to rotate. The rotation of the lead screw 510 causes the threaded block 512 to move stably within the stroke groove 502. Subsequently, the threaded block 512 drives the clamping plate 513 and the upper needle tube slot 514 to move synchronously, clamping and positioning the needle tubes. The reverse operation removes the restriction on the needle tubes, thereby achieving synchronous clamping and positioning of multiple needle tubes, improving clamping stability, preventing displacement and skewing during grinding, and improving grinding quality.

A hollow plate 605 is connected to one end of the second delivery pipe 604. Both sides of the hollow plate 605 are bolted to one side of the upper end of the clamping plate 513. Multiple spray heads 606 are connected to the front of the hollow plate 605.

[0054] In this embodiment, when the needle tube is clamped and polished, the polishing fluid is transported to the second delivery pipe 604 through the pump 602 and the first delivery pipe 603, and then to the hollow plate 605 through the second delivery pipe 604. The polishing fluid is then transported to the spray head 606 through the hollow plate 605, and then sprayed onto the needle tube through the spray head 606. This reduces the friction temperature during the polishing process, reduces scratches on the needle tube surface, washes away the polishing debris, and improves the polishing smoothness and processing quality of the needle tube.
