Description

Technical Field

[0001] The utility model relates to the technical field of shaft sleeve processing, in particular to a shaft sleeve processing tool. Background Art

[0002] The shaft sleeves of stainless steel stamping pumps are mostly processed directly from profiles. Since there is no tolerance requirement for the outer diameter of the shaft sleeve, there is no need to process the outer circle of the shaft sleeve. It is only necessary to ensure the parallelism of the two end surfaces of the shaft sleeve.

[0003] At present, factories generally use grinders to process the end faces of sleeves, that is, inserting the sleeve into the mandrel, then clamping the mandrel through the clamping mechanism on the grinder, and then grinding the two end faces through the grinder. However, with this processing method, only one sleeve can be ground at a time, the work efficiency is low, and there are processing tolerances between the sleeves due to the processing amount, resulting in poor consistency. Utility Model Content

[0004] In order to solve the above-mentioned deficiencies of the prior art, the utility model provides a shaft sleeve processing tooling to achieve batch grinding of shaft sleeves, improve processing efficiency and ensure processing consistency.

[0005] The technical solution of the utility model is: a sleeve processing tool, including a base, a clamping seat and a positioning baffle, the upper surface of the base is provided with a plurality of positioning grooves spaced along the length direction, the lower surface of the clamping seat has a positioning surface that cooperates with the positioning groove to clamp the sleeve, the clamping seat is connected to the base via a driving member and moves in the direction of approaching / moving away from the base, the positioning baffle is detachably mounted on one side of the base and there is a processing gap between the positioning baffle and the base. The base and the clamping seat are clamped and fixed with the positioning grooves and the positioning surface, thereby realizing batch grinding of the sleeves and improving processing efficiency. At the same time, the positioning baffle can align the end faces of one side of the plurality of sleeves before processing, ensuring that the processing amount of the batch sleeves is the same and improving the consistency between the sleeves.

[0006] The lower end of one side of the base extends outward to form a reference portion, the inner side of the positioning baffle abuts against the outer side of the reference portion, and the positioning baffle is detachably connected to the base via a positioning bolt.

[0007] The lower end of one side of the base extends outward to form a reference portion, the upper surface of the reference portion is provided with a slot along the length direction, and the lower end of the positioning baffle is provided with a plug-in portion matched with the slot.

[0008] The driving member is an adjusting bolt, a through hole is provided in the middle of the clamping seat, a thread groove is provided in the middle of the upper surface of the base, and the adjusting bolt passes through the through hole and is matched with the thread groove.

[0009] It includes a pressure cover, and hinged parts are extended downward from both ends of the clamping seat. The top of the pressure cover is hinged to the hinged part through an ear plate, and the hinge axis direction of the hinged part is perpendicular to the length direction of the base. The bottom of the pressure cover forms the positioning surface.

[0010] There are four positioning grooves, each positioning surface corresponds to two positioning grooves, and there is a movable gap between the through hole and the adjusting bolt. The movable gap between the through hole of the clamping seat and the adjusting bolt provides an offset margin for both ends of the clamping seat, and the hinged connection of the pressure cover enables the pressure cover to have an adaptive offset capability, which can ensure the stability of the tooling clamping when clamping four shaft sleeves with outer diameter tolerances.

[0011] The positioning groove is a V-shaped groove with its opening facing upward. The design of the V-shaped groove can be used to clamp shaft sleeves with different outer diameters to improve the applicability of the tooling.

[0012] The base is made of a metal material that can be attracted by a magnet, and a base extending toward the periphery of the base is formed at the bottom of the base, and the base is adsorbed on the magnetic absorption table of the grinder through the base. The size of the base is larger than the base, which can increase the contact area between the tooling and the magnetic absorption table, thereby ensuring that it is stably adsorbed on the magnetic absorption table.

[0013] An anti-skid pad is adhered to the bottom of the gland.

[0014] The beneficial effects of the utility model are as follows: multiple sleeves are clamped and fixed by the positioning grooves and positioning surfaces on the base and the clamping seat, thereby realizing batch grinding of the sleeves and improving processing efficiency; at the same time, the positioning baffle can align one side end faces of multiple sleeves before processing, ensuring that the processing amount of batch sleeves is the same and improving the consistency between the sleeves.

[0020] In order to enable those skilled in the art to better understand the technical solution in the utility model, the technical solution in the utility model is clearly and completely described below in conjunction with the accompanying drawings. Other embodiments obtained by those skilled in the art without making any creative work should all fall within the protection scope of the utility model.

[0021] like Figure 1 As shown, the utility model provides a shaft sleeve processing tool, including a base 1, a clamping seat 2 and a positioning baffle 6. The upper surface of the base 1 is provided with a plurality of positioning grooves 101 at intervals along the length direction. The lower surface of the clamping seat 2 has a positioning surface that cooperates with the positioning grooves 101 to clamp the shaft sleeve 5. The clamping seat 2 is connected to the base 1 via a driving member and moves in a direction approaching / away from the base 1. The positioning grooves 101 and the positioning surfaces on the base 1 and the clamping seat 2 are used to clamp and fix a plurality of shaft sleeves 5, thereby realizing batch grinding of the shaft sleeves 5 and improving the processing efficiency. The positioning baffle 6 is detachably mounted on one side of the base 1 and there is a processing gap between the positioning baffle 6 and the base 1. Preferably, the length of the shaft sleeve 5 is greater than the sum of the width of the base 1 and the processing gap. The positioning baffle 6 is used to position and align the portion of the shaft sleeve 5 extending out of the base 1 on one side, so that the portion of the shaft sleeve 5 extending out of the base 1 has the same processing amount, thereby ensuring the consistency of processing between the shaft sleeves 5.

[0022] like Figure 3 In Example 1, the lower end of one side of the base 1 extends outward to form a reference portion 102, and the height of the reference portion 102 is lower than the height of the lowest point of the positioning groove 101. The inner side of the positioning baffle 6 abuts against the outer side of the reference portion 102, and the positioning baffle 6 is detachably connected to the base 1 via the positioning bolt 7. At this time, the width of the reference portion 102 is the processing gap.

[0023] Further preferably, the driving member is an adjusting bolt 3, a through hole is provided in the middle of the clamping seat 2, a thread groove is provided in the middle of the upper surface of the base 1, and the adjusting bolt 3 passes through the through hole and is connected with the thread groove. By tightening the adjusting bolt 3, a downward clamping force is provided to the clamping seat 2, so that the sleeve 5 is clamped between the positioning surface of the clamping seat 2 and the positioning groove 101 of the base 1.

[0024] like Figure 2 As shown, the processing tool also includes a pressure cover 4, and hinged parts 201 are extended downward at both ends of the clamping seat 2. The top of the pressure cover 4 is hinged to the hinged part 201 through an ear plate, and the hinge axis direction of the hinged part 201 is perpendicular to the length direction of the base 1. The bottom of the pressure cover 4 forms the positioning surface. Preferably, in order to avoid interference of the pressure cover 4 with the processing amount of the shaft sleeve 5 during grinding, the width of the pressure cover 4 is smaller than the width of the base 1.

[0025] Further preferably, there are four positioning grooves 101, each positioning surface corresponds to two positioning grooves 101, and there is a movable gap between the through hole and the adjusting bolt 3. The movable gap between the through hole of the clamping seat 2 and the adjusting bolt 3 provides an offset margin for both ends of the clamping seat 2, and the hinged mode of the gland 4 enables the gland 4 to have an adaptive offset capability. When clamping four sleeves 5 with outer diameter tolerances, the positioning surface of the gland 4 can always be in line contact with the upper surface of each sleeve 5, and at least two line contacts exist between the lower surface of the sleeve 5 and the groove wall of the positioning groove 101, thereby ensuring that the sleeve 5 is stably clamped between the gland 4 and the positioning groove 101.

[0026] In order to enable the processing tool to clamp the shaft sleeves 5 of different sizes (ie different models), the positioning groove 101 is a V-shaped groove with the opening facing upward.

[0027] In order to ensure the stability of the processing tool on the grinding machine, the base 1 is made of metal material that can be attracted by a magnet. Preferably, an iron base 1 is selected, and the bottom of the base 1 is integrally formed with a base 103 extending to the side of the base 1. The large-sized base 103 allows the base 1 to be more stably adsorbed on the magnetic suction table of the grinder.

[0028] In order to ensure the clamping force of the gland 4 on the shaft sleeve 5, an anti-skid pad is adhered to the bottom of the gland 4.

[0029] like Figure 4 As shown, the difference between Example 2 and Example 1 is that the lower end of one side of the base 1 extends outward to form a reference portion 102, a slot is provided on the upper surface of the reference portion 102 along the length direction, and the lower end of the positioning baffle 6 has a plug-in portion 601 that matches the slot. At this time, the distance between the slot and the base 1 is the processing gap.

[0030] Taking Example 1 as an example, when implementing the technical solution, the processing device is placed on the magnetic suction table of the grinding machine, the positioning baffle 6 is fixed to the base 1 through the positioning bolt 7, and the inner side of the positioning baffle 6 is against the outer side of the reference part 102 of the base 1. At this time, the four shaft sleeves 5 to be processed are placed on the positioning groove 101 of the base 1, and one end of the shaft sleeve 5 is against the inner side of the positioning baffle 6. The adjusting bolt 3 is tightened. At this time, each gland 4 is respectively pressed on the upper surface of the two lower shaft sleeves 5, and the lower surface of the gland 4 and the V-shaped positioning groove 1 The groove surfaces on both sides of 01 form three line contacts with the sleeve 5, completing the fixation of the sleeve 5 on the tooling, removing the positioning baffle 6, grinding the positioned end face of the sleeve 5 with the grinding tool, grinding the end face of the sleeve 5 to be flush with the side face of the base 1, turning the processing tooling over, and grinding the other end face of the sleeve 5, grinding the other end face of the sleeve 5 to be flush with the other side of the base 1, completing the grinding process, loosening the adjusting bolt 3, taking out the bearing, and then putting in the next four sleeves 5 to be processed, and repeating the above steps.
