Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of bushing chamfering equipment, and in particular to a bushing chamfering device. Background Technology
[0002] Chamfering of bushings refers to the process of cutting the edges of bushings into a certain bevel. Chamfering is used to remove burrs generated by machining on parts and to facilitate assembly. Generally, chamfers need to be made at the ends of bushings. Existing bushing chamfering devices typically grind and chamfer the bushing from both ends. However, during the chamfering process, metal chips fly, which is not conducive to cleaning and tidying up the machining workshop and the chamfering device. Over time, this may lead to a decrease in the chamfering accuracy of the entire chamfering device. Based on this, a bushing chamfering device is proposed. Utility Model Content
[0003] To solve the technical problem of metal shavings splashing during the chamfering process, this utility model provides a chamfering device for bushing processing.
[0004] This utility model is achieved using the following technical solution: a bushing chamfering device, comprising a processing table, an arc-shaped limiting plate fixedly connected to the lower side of the processing table, a limiting groove formed inside the arc-shaped limiting plate, an arc-shaped baffle slidably connected to the inner side of the limiting groove, a baffle pushing mechanism provided on the lower side of the processing table, chamfering and grinding mechanisms provided on both sides of the processing table, a clamping mechanism for installing and fixing the bushing provided on the upper side of the processing table, and a clamping and positioning unit provided on the upper side of the processing table.
[0005] As a further improvement to the above solution, the baffle pushing mechanism includes a limiting plate fixedly connected to the lower side of the processing table, a threaded sleeve rotatably connected between the limiting plate and the lower side of the processing table, and a push rod mechanism provided on the outer side of the threaded sleeve.
[0006] As a further improvement to the above solution, the push rod mechanism includes a swing rod fixedly connected to the outer sides of both ends of the threaded sleeve, and push rods fixedly connected to both sides of the bow-shaped baffle. Each push rod extends outward along the limiting groove, and the end of each push rod away from the bow-shaped baffle is rotatably connected to one end of the swing rod.
[0007] As a further improvement to the above solution, the chamfering and grinding mechanism includes multiple slide rods fixedly connected to both sides of the processing table. A slide table is slidably connected to multiple slide rods on each side. A grinding unit is fixedly connected to the upper side of two slide tables. A threaded sleeve rotating mechanism for rotating the threaded sleeve is provided on the side of one of the slide tables near the processing table. A slide table pushing mechanism for reciprocating left and right movement of the slide table is provided at one end of the slide rod.
[0008] As a further improvement to the above solution, the threaded sleeve rotating mechanism includes a threaded column fixedly connected to one of the slides, and the threaded column is configured to cooperate with the threaded sleeve.
[0009] As a further improvement to the above solution, the slide push mechanism includes a fixed plate that is fixedly connected to one end of a plurality of slide rods on each side. A hydraulic cylinder is installed on the side of the fixed plate away from the slide, and the output end of the hydraulic cylinder on each side passes through the fixed plate and is connected to the slide.
[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0011] 1. This utility model uses a threaded column to drive the threaded sleeve to rotate, which indirectly drives the swing rod to push the bow-shaped cover out from the inside of the limiting slide groove. When chamfering, the bow-shaped cover is located in the space above the clamping and positioning unit, which can effectively prevent iron filings from splashing during chamfering and facilitate the cleaning and tidying of the process by the workers.
[0012] 2. When the grinding units on both sides of the bushing are in contact with the grinding units on both sides during chamfering, the clamping and positioning units are located below the bow-shaped guard at the same time. The sharp metallic noise generated by chamfering can be effectively reduced by the bow-shaped guard. Attached Figure Description

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.
[0020] Example:
[0021] Please combine Figure 1 - Figure 4 This embodiment of a bushing chamfering device includes a machining table 1, with an arc-shaped limiting plate 4 fixedly connected to the lower side of the machining table 1, such as... Figure 4 As shown, a limiting groove 5 is provided inside the arc-shaped limiting plate 4. The limiting groove 5 on the arc-shaped limiting plate 4 is through-cut. An arc-shaped baffle 15 is slidably connected to the inner side of the limiting groove 5. The arc-shaped baffle 15 can freely enter and exit the arc-shaped limiting plate 4. The hidden design helps to reduce the space occupied by the device. A baffle pushing mechanism is provided on the lower side of the processing table 1. Chamfering and grinding mechanisms are provided on both sides of the processing table 1. A clamping mechanism for installing and fixing the bushing is provided on the upper side of the processing table 1. A clamping and positioning unit 2 is provided on the upper side of the processing table 1.
[0022] When the two ends of the push shaft sleeve are ground and chamfered, the flying metal chips generated can be effectively blocked by the bow-shaped baffle 15, so that the generated metal chips fall onto the processing table 1, which makes it easier for the staff to clean up the metal chips uniformly.
[0023] Please combine Figure 3 As shown, the baffle pushing mechanism includes a limiting plate 12 fixedly connected to the lower side of the processing table 1. The limiting plate 12 is a semi-cylindrical design, and its outline is similar to that of the threaded sleeve 6. The threaded sleeve 6 is rotatably connected between the limiting plate 12 and the lower side of the processing table 1. A bearing assembly is provided between the threaded sleeve 6 and the processing table 1 to reduce wear. A push rod mechanism is provided on the outer side of the threaded sleeve 6.
[0024] It should be noted that the threaded sleeve 6 has a helical structure inside, which meshes with the threaded column 7 for drive, and can rotate in both forward and reverse directions.
[0025] Please combine Figure 3 As shown, the push rod mechanism includes a swing rod 13 that is fixedly connected to the outer sides of both ends of the threaded sleeve 6. Push rods 14 are fixedly connected to both sides of the bow-shaped cover 15. Each push rod 14 extends outward along the limiting slide groove 5, and the end of each push rod 14 away from the bow-shaped cover 15 is rotatably connected to one end of the swing rod 13.
[0026] Please combine Figure 1As shown, the chamfering and grinding mechanism includes two slide rods 3 fixedly connected to both sides of the processing table 1. A slide table 8 is slidably connected to each of the two slide rods 3 on each side. A grinding unit 11 is fixedly connected to the upper side of each of the two slide tables 8. The grinding unit 11 mainly consists of a motor and a chuck structure. Different chamfering grinding tools can be loaded through the chuck structure. A threaded sleeve rotating mechanism that rotates the threaded sleeve 6 is provided on the side of one of the slide tables 8 near the processing table 1. A slide table pushing mechanism that moves the slide table 8 back and forth is provided at one end of the slide rod 3.
[0027] Please combine Figure 1 As shown, the threaded sleeve rotating mechanism includes a threaded post 7 fixedly connected to one of the slides 8. The threaded post 7 is configured to cooperate with the threaded sleeve 6. When the threaded post 7 is inserted into the threaded sleeve 6, the threaded sleeve 6 rotates clockwise, and the bow-shaped cover 15 rises from the limiting groove 5 on one side. Conversely, when the threaded post 7 is pulled out from the threaded sleeve 6, the threaded sleeve 6 rotates counterclockwise, and the bow-shaped cover 15 is hidden back inside the limiting groove 5.
[0028] Please combine Figure 1 As shown, the slide push mechanism includes a fixed plate 10 that is fixedly connected to one end of a plurality of slide rods 3 on each side. A hydraulic cylinder 9 is installed on the side of the fixed plate 10 away from the slide 8. In this embodiment, the hydraulic cylinder 9 is used to push the slide 8. In other embodiments, electric cylinders, pneumatic cylinders or other drive structures can be used. The output end of the hydraulic cylinder 9 on each side passes through the fixed plate 10 and is connected to the slide 8.
[0029] The implementation principle of the bushing chamfering device in this embodiment is as follows: When the chamfering process is started, the hydraulic cylinder 9 pushes the slides 8 on both sides to move to one side along the slide rod 3, so that the grinding wheel on the grinding unit contacts and grinds the two ends of the bushing. At this time, the threaded post 7 on one side of one of the slides 8 is gradually inserted into the threaded sleeve 6. During the insertion of the threaded sleeve 6, the threaded sleeve 6 rotates, which drives the rocker arm 13 to rotate. One end of the rocker arm 13 pushes the push rod 14 to rotate circumferentially, so as to push the bow-shaped cover 15 out of the limiting slide groove 5. The bow-shaped cover 15 appears from one side of the arc-shaped limiting plate 4 and rotates to the other side of the processing table 1, so as to block the space above the clamping and positioning unit 2. The metal chips generated by chamfering can be effectively blocked by the bow-shaped cover 15, so as to prevent the metal chips from splashing.
[0030] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
