Moreover, the bushing 1 is clamped on the milling machine by using a bench vise or similar clamping tools. However, this clamping method will damage the outer wall of the bushing 1, and the operation is time-consuming and labor-intensive, which is not convenient for the rapid loading and unloading of the bushing 1, and will also affect the processing efficiency of the bushing 1.

[0028] To make the technical means, creative features, objectives, and effects of this invention clearer and easier to understand, the invention will be further described below in conjunction with the accompanying drawings and specific embodiments:

[0029] like Figure 2 , Figure 4 as well as Figure 6 As shown, an embodiment of the present invention provides a bushing oil groove processing device, comprising: a base 2, on which an adjustment mechanism is provided; a support mechanism, which is disposed on the base 2 and movably connected to the adjustment mechanism, the adjustment mechanism being used to drive the support mechanism to move to any position on a horizontal plane; an installation mechanism, comprising a plurality of parallelly arranged installation components, each installation component comprising a plurality of installation parts arranged linearly at intervals, each installation part comprising a telescopic member, a limiting member, and a spreading member, the fixed end of the telescopic member being installed inside the support mechanism, the telescopic end of the telescopic member vertically and freely passing through the support mechanism and being fixedly connected to the spreading member, the limiting member being sleeved outside the telescopic end of the telescopic member and located between the spreading member and the support mechanism, the telescopic member being used to drive the spreading member to embed into the limiting member and spread it open; and a milling mechanism, which is located directly above the plurality of installation parts of any installation component.

[0030] Each bushing 1 is fitted onto the corresponding limiting member. Then, each telescopic member is activated to drive the opening member to embed into the limiting member, opening the limiting member so that it abuts against the inside of the bushing 1, thus fixing the position of the bushing 1. Subsequently, each bushing 1 is machined with an oil groove 11 using a milling mechanism. After machining, each telescopic member is activated again to drive the opening member to exit the limiting member, so that the limiting member disengages from the inside of the bushing 1. Then, the bushing 1 can be removed and replaced. The operation is simple and convenient, can quickly fix the bushing 1, and can process multiple bushings 1 at once, improving the machining efficiency of the bushing 1 and saving time and effort.

[0031] like Figure 2-5As shown in another embodiment of the present invention, the bushing oil groove processing device further optimizes the limiting member, telescopic member, and opening member included therein. The limiting member includes an elastic limiting sleeve 52 sleeved on the outside of the telescopic end of the telescopic member. The side wall of the elastic limiting sleeve 52 has a plurality of first opening through grooves 53 vertically downward from its upper end, and a plurality of second opening through grooves 54 vertically upward from its lower end. The plurality of first opening through grooves 53 and the plurality of second opening through grooves 54 are arranged alternately along the circumference of the elastic limiting sleeve 52. Preferably, the elastic limiting sleeve 52 is made of elastic metal, and the groove width of the first opening through groove 53 is greater than the groove width of the second opening through groove 54, so that the opening member can more stably open the elastic limiting sleeve 52 during the insertion process, and the elastic limiting sleeve 52 can autonomously return to its original position after the opening member is removed from the elastic limiting sleeve 52.

[0032] The telescopic component includes a telescopic cylinder 5. The fixed end of the telescopic cylinder 5 is fixedly installed in the support mechanism. The telescopic end of the telescopic cylinder 5 freely passes through the support mechanism and is fixedly connected to the expansion component. The elastic limiting sleeve 52 is sleeved on the outside of the telescopic end of the telescopic cylinder 5. The telescopic cylinder 5 is connected to the air pipe 56 and the external air source through the connector 57.

[0033] The spreading member includes a spreading disc 51 that is coaxially and fixedly connected to the telescopic end of the telescopic cylinder 5. The spreading disc 51 is used to be embedded in the elastic limiting sleeve 52 and to be interference-fitted with it. Preferably, the end face radius of the spreading disc 51 near the elastic limiting sleeve 52 is small, which makes it easier for the spreading disc 51 to be embedded in the elastic limiting sleeve 52.

[0034] When fixing the bushing 1, the telescopic cylinder 5 is activated to drive the spreading disc 51 to move downward and embed into the elastic limiting sleeve 52, so as to spread the elastic limiting sleeve 52 and make the elastic limiting sleeve 52 abut against the inner wall of the bushing 1, thereby fixing the bushing 1; when removing the bushing 1, the telescopic cylinder 5 is activated to drive the spreading disc 51 to move upward to remove the elastic limiting sleeve 52. At this time, since the elastic limiting sleeve 52 itself is elastic, it can recover on its own, so that the elastic limiting sleeve 52 disengages from the inner wall of the bushing 1, and then the bushing 1 can be removed.

[0035] like Figure 2 As shown, according to another embodiment of the present invention, the bushing oil groove processing device further optimizes its supporting mechanism. The supporting mechanism includes a horizontally arranged supporting plate 3 and a fixed frame 4 fixedly installed above the supporting plate 3. The fixed frame 4 is U-shaped. The fixed end of each telescopic cylinder 5 is located inside the fixed frame 4 and fixedly connected to the supporting plate 3. The telescopic end of each telescopic cylinder 5 freely extends out of the fixed frame 4. The adjusting mechanism is located between the bottom of the supporting plate 3 and the base 2.

[0036] like Figure 2 as well as Figure 6-7 As shown in another embodiment of the present invention, the bushing oil groove processing device further optimizes its adjustment mechanism. The base 2 has an upper mounting groove 21, and the support plate 3 has a connecting block 31 fixedly mounted at its bottom. The adjustment mechanism includes two sliding plates 22, two screws 24, and two motors 25. The two sliding plates 22 are cross-shaped and each sliding plate 22 is slidably mounted between two opposing inner walls of the mounting groove 21. Each sliding plate 22 has a vertically extending sliding hole 23 along its length. The two screws 24 are threadedly connected to one end of each of the two sliding plates 22. Each screw 24 is rotatably mounted on... Between the two opposing inner walls of the mounting groove 21, two motors 25 are fixedly installed in the upper part of the base 2. One end of each of the two screws 24 freely passes through the mounting groove 21 and is coaxially and fixedly connected to the power output shaft of the two motors 25. The connecting block 31 freely passes through the intersection of the two sliding holes 23 and is slidably connected to both sliding holes 23. When the two motors 25 are started, the two screws 24 are driven to rotate. The rotation of the screws 24 drives the two sliding plates 22 to slide, thereby causing the connecting block 31 to slide relative to the two sliding holes 23, so that the support plate 3 can move to any position on the horizontal plane, so that the milling mechanism can process the oil groove 11 on the bushing 1.

[0037] like Figure 2 As shown, according to another embodiment of the present invention, the bushing oil groove processing device further optimizes the milling mechanism, which includes a bracket 6 fixedly connected to the base 2, a drive member fixedly mounted on the bracket 6, and a plurality of milling parts 8 connected to the power output end of the drive member. The plurality of milling parts 8 are located one-to-one above the elastic limiting sleeve 52 of each mounting component. The drive member is used to drive the plurality of milling parts 8 to move in the vertical direction. The specific structure of each milling part 8 is disclosed in Chinese Utility Model Patent No. CN212264664U, and will not be described in detail here.

[0038] The driving component includes a hydraulic rod 7 and a connecting plate 71. The hydraulic rod 7 is arranged vertically, with its fixed end fixedly connected to the bracket 6 and its telescopic end fixedly connected to the connecting plate 71. Several milled groove parts 8 are arranged linearly at intervals on the lower part of the connecting plate 71. The hydraulic rod 7 is driven by an external hydraulic oil station.

[0039] The bracket 6 has an L-shaped structure. The free end of the vertical section of the bracket 6 is fixedly connected to the base 2. The horizontal section of the bracket 6 is arranged towards the elastic limiting sleeve 52. The fixed end of the hydraulic rod 7 is fixedly installed on the upper part of the horizontal section of the bracket 6. The telescopic end of the hydraulic rod 7 freely passes through the horizontal section of the bracket 6 and is fixedly connected to the connecting plate 71.

[0040] like Figure 2 and Figure 4As shown, according to another embodiment of the present invention, the bushing oil groove processing device preferably has a plurality of fixing plates 55 fixedly installed on the fixing frame 4, and the plurality of fixing plates 55 are respectively sleeved on the outer side of the telescopic end of the telescopic cylinder 5; when the telescopic cylinder 5 drives the opening plate 51 to be embedded in the elastic limiting sleeve 52, the elastic limiting sleeve 52 abuts against the fixing plate 55, so that the fixing plate 55 can support the elastic limiting sleeve 52, so that the elastic limiting sleeve 52 does not directly contact the fixing frame 4, thereby preventing the elastic limiting sleeve 52 from causing wear to the fixing frame 4 after long-term use.

[0041] The working principle of this invention is as follows: When using this invention, several bushings 1 are fitted one-to-one onto several limiting sleeves. Then, the telescopic cylinder 5 is activated to drive the spreading disc 51 downwards and embed it into the elastic limiting sleeve 52, thus spreading the elastic limiting sleeve 52 so that it abuts against the inner wall of the bushing 1, thereby fixing the bushing 1. Subsequently, the hydraulic rod 7 is activated to drive the connecting plate 71 and several milled groove parts 8 downwards to process the oil groove 11 in each elastic limiting sleeve 52. During the processing, two motors 25 are activated to drive two screws 24 to rotate. 24. Rotation drives the two sliding plates 22 to slide, causing the connecting block 31 to slide relative to the two sliding holes 23, so that the support plate 3 can move to any position on the horizontal plane, thereby enabling the milling part 8 to process each oil groove 11 on each elastic limiting sleeve 52; after processing, the hydraulic rod 7 is started to drive the connecting plate 71 and several milling parts 8 to move upward, and then the telescopic cylinder 5 is started to drive the opening plate 51 to move upward and exit the elastic limiting sleeve 52, so that the elastic limiting sleeve 52 returns to its original state. Then the bushing 1 can be removed and replaced.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
