Description

Technical Field

[0001] This utility model relates to the field of circular knitting needle cylinder processing technology, and more specifically, to a deburring device for circular knitting needle cylinders. Background Technology

[0002] In existing technology, before the production of cylindrical syringes, the cylindrical syringes of the cylindrical syringes are machined to remove burrs from the outer and inner walls. After that, the cylindrical syringes need to be grouted to create needle grooves on the outer wall. After grooving, burrs may be generated at the edges of the grooves. The existing method is to remove burrs by grinding the outer wall of the syringe. However, burrs may deform and enter the grooves. Grinding the outer wall alone cannot effectively remove burrs. Therefore, a technical solution is needed to solve the above problems. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art, achieve better deburring effect, and provide a deburring device for a circular needle cylinder.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] This utility model discloses a deburring device for a circular syringe, including a base plate, a first polishing component, and a deburring component. A rotating chuck is installed at the center of the base plate. The rotating chuck is rotatable and can hold the syringe. The first polishing component and the deburring component are located in the rotation direction of the syringe. The first polishing component includes a rotatable first polishing wheel and a first lifting device. The outer wall of the first polishing wheel abuts against the outer wall of the syringe. The first lifting device drives the first polishing wheel to move up and down reciprocally. The deburring component includes a second lifting device and a cutting component. The cutting component includes a cutting blade. The outer wall of the syringe is provided with multiple needle grooves. The cutting blade can enter and pass through the needle grooves. The blade of the cutting blade can adhere to the inner sidewall of the needle groove.

[0006] Furthermore, the cutting blade includes a blade head, which includes two cutting edges. The two cutting edges are arranged at an angle, and the far ends of the two cutting edges are attached to the sidewall of the needle groove.

[0007] Furthermore, the blade is provided in two parts, arranged vertically, with the cutting edges of the two blades being far apart from each other.

[0008] Furthermore, the needle groove connects the upper end face and the lower end face of the syringe.

[0009] Furthermore, the cutting assembly includes a mounting plate, the cutting blade is mounted on the mounting plate and extends radially toward the syringe, the mounting plate is connected to the second lifting device, and the second lifting device drives the mounting plate to move up and down.

[0010] Furthermore, the cutting assembly includes a limiting assembly located between the cutting blade and the syringe. The limiting assembly includes two limiting plates. When the cutting blade corresponds to one needle groove, the two limiting plates correspond to two adjacent needle grooves on both sides of the needle groove corresponding to the cutting blade.

[0011] Furthermore, there are two limiting components, which are located above and below the cutting blade, respectively.

[0012] Furthermore, the end of the limiting plate away from the cutting blade is a plug-in end, and the width of the plug-in end gradually decreases in the direction away from the cutting blade.

[0013] Furthermore, it includes a second polishing assembly, which includes a rotatable second polishing wheel. The outer wall of the syringe is provided with an annular groove. The second polishing wheel includes a first polishing surface and a second polishing surface. The first polishing surface contacts the upper and lower end faces of the annular groove, and the second polishing surface contacts the inner wall of the annular groove.

[0014] The beneficial effects of this utility model are:

[0015] This invention utilizes a cutting blade that can move up and down. By moving the blade against the side wall of the needle groove, it can deburr the inner side of the needle groove. The cutting blade can be closely attached to the side wall of the needle groove by the limiting plate, resulting in a better deburring effect. The deburring component can work with the polishing wheel to better deburr the syringe. Attached Figure Description

[0023] The technical solutions in this embodiment will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] like Figures 1-6 As shown, this embodiment discloses a deburring device for a circular knitting syringe, including a base plate 1, a first polishing assembly 2, a deburring assembly 3, and a second polishing assembly 4. A rotating chuck 11 is mounted at the center of the base plate 1. The rotating chuck 11 is rotatable and can clamp the syringe 101. The first polishing assembly 2, the deburring assembly 3, and the second polishing assembly 4 are located in the rotation direction of the syringe 101. The first polishing assembly 2 includes a rotatable first polishing wheel 22 and a first lifting device 21. The outer wall of the first polishing wheel 22 abuts against the outer wall of the syringe 101. The first lifting device 21 is a motor-driven lead screw. The first polishing wheel 22 is powered by a motor. The first lifting device 21 drives the motor connected to the first polishing wheel 22 to move up and down. The side wall of the first polishing wheel 22 is tangent to the outer wall of the syringe 101. The axial direction of the first polishing wheel 22 is perpendicular to the radial direction of the syringe 101. The first lifting device 21 drives the first polishing wheel 22 to move up and down reciprocally. The first polishing wheel 22 can polish and grind along the height direction of the syringe 101 while rotating and moving up and down. The first lifting device 21 is installed on the base plate 1. The first lifting device 21 can be manually adjusted to move closer to or further away from the syringe 101.

[0025] like Figure 1 , Figure 6As shown, the outer wall of the syringe 101 is provided with an annular groove 1012. Because the annular groove 1012 is recessed inward, the first polishing wheel 22 cannot contact the inner wall of the annular groove 1012. The second polishing assembly 4 includes a rotatable second polishing wheel 41. The second polishing wheel 41 is driven to rotate by a motor. The second polishing wheel 41 includes a first polishing surface 411 and a second polishing surface 412. The first polishing surface 411 is the annular sidewall of the second polishing wheel 41. The first polishing surface 411 contacts the upper and lower end faces of the annular groove 1012. The rotation of the second polishing wheel 41 can polish the upper and lower end faces of the annular groove 1012. The second polishing surface 412 is the end face of the second polishing wheel 41. A polishing material layer is also installed on the end face of the second polishing wheel 41. The second polishing surface 412 contacts the inner wall of the annular groove 1012. The second polishing surface 412 can grind and polish the inner wall of the annular groove 1012.

[0026] like Figure 1 As shown, the outer wall of the syringe 101 is provided with a plurality of needle grooves 1011. The needle grooves 1011 connect the upper end face and the lower end face of the syringe 101. The lower end face of the syringe 101 is spaced apart from the rotating chuck 11. The deburring assembly 3 includes a second lifting device 31 and a cutting assembly 32. The second lifting device 31 can drive the cutting assembly 32 to move up and down reciprocally. For example, after the cutting assembly 32 cuts and deburrs once through the needle grooves 1011 from top to bottom, it stops below the syringe 101. The rotating chuck 11 drives the syringe 101 to rotate, so that the cutting assembly 32 corresponds to the next adjacent needle groove 1011. The second lifting device 31 drives the cutting assembly 32 to cut and deburr once from bottom to top.

[0027] The cutting assembly 32 includes a mounting plate 321 and a cutting blade 322. The cutting blade 322 is mounted on the mounting plate 321 and extends radially toward the syringe 101. The mounting plate 321 is connected to a second lifting device 31, which drives the mounting plate 321 to move up and down. The cutting blade 322 can enter and pass through the needle groove 1011. The blade 3222 of the cutting blade 322 can adhere to the inner wall of the needle groove 1011. The cutter head 3221 includes two cutting edges 3222. The two cutting edges 3222 are inclined and their far ends are attached to the side wall of the needle groove 1011. The two cutting edges 3222 are V-shaped and can simultaneously deburr the two side wall edges of the needle groove 1011. The length of the cutting blade 322 is greater than the depth of the annular groove 1012, ensuring that the cutting blade 322 can deburr the edge of the needle groove 1011 located in the annular groove 1012.

[0028] To save travel time, the cutting assembly 32 can reciprocate. It has two cutter heads 3221, which are arranged vertically. The cutting edges 3222 of the two cutter heads 3221 are far apart from each other, and the four cutting edges 3222 are X-shaped, which can perform deburring work in two directions.

[0029] The cutting assembly 32 includes a limiting assembly 323 located between the cutting blade 322 and the syringe 101. The limiting assembly 323 includes two limiting plates 3231. When the cutting blade 322 corresponds to one needle groove 1011, the two limiting plates 3231 respectively correspond to two adjacent needle grooves 1011 on both sides of the needle groove 1011 corresponding to the cutting blade 322. The limiting plates 3231 contact and insert into the needle groove 1011 earlier than the cutting blade 322, thus providing a positioning function for the cutting blade 322. Meanwhile, the limiting plate 3231 can support the needle groove 1011 and provide support when the cutting blade 322 enters to cut and deburr, preventing deformation of the part between the two needle grooves 1011, so that the cutting blade 322 can better contact the side wall of the needle groove 1011 for operation. The end of the limiting plate 3231 away from the cutting blade 322 is the insertion end 3232. The width of the insertion end 3232 gradually decreases in the direction away from the cutting blade 322, so that the limiting plate 3231 can be better inserted into the needle groove 1011.

[0030] Since the cutting assembly 32 can reciprocate to save stroke, two limiting components 323 are provided. The two limiting components 323 are located above and below the cutting blade 322 respectively, which can limit the cutting blade 322 and support the part between the two needle grooves 1011 when operating in both directions.

[0031] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
