Description

Technical Field

[0001] This utility model relates to the field of shaft sleeve processing technology, and in particular, to a bearing sleeve groove processing equipment. Background Technology

[0002] In the production of bushing-type parts, it is often necessary to create annular grooves on the outer wall of the workpiece. These grooves serve various purposes, such as for inserting sealing rings, snap rings, or retaining rings, and also as storage spaces for lubricating oil to reduce friction. Traditional manufacturing methods involve creating these grooves using machine tools such as lathes, grinders, or milling machines. However, these methods require clamping each workpiece individually, resulting in low efficiency and unsuitability for mass production.

[0003] People gradually discovered that thread rolling machines could be used to create annular grooves on bushing-type parts, simply by replacing the threads on the thread rolling plate with protrusions. The protrusions press against the workpiece, causing it to rotate during the rolling motion, thus creating the annular groove. However, the protrusions are usually integrated with the plate, which means that the entire thread rolling plate needs to be replaced when machining annular grooves of different sizes, ultimately increasing production costs. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a bearing sleeve groove processing equipment.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] A bearing sleeve groove processing device includes a thread rolling machine body. A grooving plate is provided on the execution end of the thread rolling machine body. The grooving plate includes a plate body. A plurality of mounting grooves are arranged side by side on the plate body. Connecting pieces are detachably provided in the mounting grooves. The plurality of connecting pieces are assembled to form grooving protrusions.

[0007] Preferably, the lengths of the connecting pieces increase sequentially in the transverse direction, and each connecting piece has a mating surface at its end, and the mating surfaces are joined together to form a guide slope.

[0008] Preferably, the mounting groove is a dovetail groove.

[0009] Preferably, at least one end of the mounting groove along the longitudinal direction is open.

[0010] Preferably, one end of the mounting groove along the longitudinal direction is open, and the other end forms an abutment surface.

[0011] Preferably, the longitudinal positions of the plurality of abutment surfaces are aligned.

[0012] Preferably, an electromagnet is provided inside the plate, and the electromagnet uses magnetic force to attract and fix the connecting piece.

[0013] Preferably, the electromagnet is a power-off retention type electromagnet.

[0014] Preferably, the connecting piece is fixed to the plate by bolts.

[0015] The beneficial effects of this utility model are: compared with the prior art, the grooving protrusion is composed of several connecting pieces, so the size of the grooving protrusion can be adjusted by adjusting the number of connecting pieces and the height of the connecting pieces, thus eliminating the need to replace the entire grooving plate and greatly reducing production costs.

[0019] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. 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.

[0020] like Figure 1 , Figure 2 As shown, a bearing sleeve groove processing device includes a thread rolling machine body 1, which may include a machine body and a feeding mechanism, a pushing mechanism, and a rolling mechanism disposed on the machine body. As those skilled in the art will know, the rolling mechanism has a reciprocating actuator end, on which a movable thread rolling plate is disposed, and the rolling mechanism also has a fixed thread rolling plate, and the processing of the external thread of the workpiece is achieved by the cooperation of the two thread rolling plates.

[0021] Unlike the conventional use of a thread rolling machine, the aforementioned actuator is equipped with a grooving plate 2. The grooving plate 2 specifically includes a plate body 3, on which several mounting grooves 4 are arranged side by side, and connecting pieces 5 are detachably installed in the mounting grooves 4. Grooving protrusions 6 can be formed by assembling several connecting pieces 5.

[0022] The connecting piece 5 may include an embedded portion and a protruding portion from bottom to top. The embedded portion is snapped into the mounting groove 4, while the protruding portion extends out of the mounting groove 4 and is spliced ​​with the adjacent protruding portion. In a specific example, the mounting groove 4 may be a dovetail groove, and the embedded portion has a cross-sectional structure adapted to it to prevent the connecting piece 5 from detaching from the plate 3 vertically.

[0023] Furthermore, the mounting groove 4 can be specifically constructed such that both ends are open (9) along the longitudinal direction. This facilitates the processing of the mounting groove 4, for example, it can be cut out quickly and at low cost using wire cutting. Alternatively, the mounting groove 4 can also be a blind groove, that is, one end of the mounting groove 4 along the longitudinal direction is open (9), and the other end is closed, with an abutment surface (10) formed at the closed end. In this case, the connecting piece 5 can be easily slid in and engaged with the mounting groove 4 through the opening (9), and achieves positioning in the length direction after contacting the abutment surface (10).

[0024] For example, the abutments of several mounting slots 4 can be in relatively accurate positions in the longitudinal direction, which makes it easier to control and measure the length of each connecting piece 5 to ensure that it is in place.

[0025] In a preferred embodiment, the grooving protrusion 6 can be formed by splicing together several connecting pieces 5 of varying lengths. Specifically, the lengths of the connecting pieces 5 increase sequentially along the transverse direction, and each connecting piece 5 has a mating surface 7 at its end. The mating surfaces 7 are then spliced ​​together to form a guiding inclined surface 8. Furthermore, during grooving, the narrower end of the grooving protrusion 6 first abuts against the workpiece, which is equivalent to creating a grooving operation with gradually increasing cutting amount on the workpiece, ensuring that the impact between the workpiece and the grooving plate 2 is not excessive.

[0026] In some embodiments, an electromagnet (not shown) may be provided inside the plate 3 to attract and fix the connecting piece 5 using its magnetic force. For example, the electromagnet is preferably a power-off retention type electromagnet. A power-off retention type electromagnet is a special type of electromagnet designed to maintain a certain level of magnetism even after the power is off, thus maintaining its original attraction. This is usually achieved by adding a permanent magnet to the electromagnet. When the electromagnet is energized, the magnetic field generated by the coil weakens the magnetic field of the permanent magnet, allowing the electromagnet to attract or release the attracted object. When the power is off, the magnetic field of the permanent magnet is restored, thus maintaining the electromagnet's attraction. This eliminates the need for a constant power supply to the grooving plate 2, providing greater ease of use. Of course, the magnetic force range of the electromagnet can be optimized to prevent workpieces from being attracted.

[0027] As an alternative, the connecting piece 5 can also be fixed to the plate 3 by bolt pressing, a method that is well known to those skilled in the art and will not be described in detail here. In one possible example, a bent portion can be provided at the end of the connecting piece 5, the bent portion fitting against the side wall of the plate 3, and bolts can be fitted onto the bent portion to press and fix the bent portion to the plate 3.

[0028] The above description is merely a preferred embodiment of this utility model. It should be understood that this utility model is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the concept described herein through the above teachings or related technologies or knowledge. Modifications and variations made by those skilled in the art that do not depart from the spirit and scope of this utility model should be protected within the scope of the appended claims.
