DETAILED DESCRIPTION

[0029] In order to further understand the features, technical means, specific objectives and functions achieved by the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] like Figure 1 、 Figure 2 and Figure 3 As shown, the present invention provides:

[0031] A clamping device for processing an adapter shaft hole includes a clamping platform 1, a driving component 2, a first clamping component 3 and a second clamping component 4. The driving component 2 is arranged on the clamping platform 1, and the first clamping component 3 and the second clamping component 4 are synchronously slidably arranged on the clamping platform 1. The first clamping component 3 and the second clamping component 4 can both be driven by the driving component 2 and clamp the adapter 5 in a releasable manner. The first clamping component 3 and the second clamping component 4 are in a released state after being separated from the driving component 2.

[0032] The adapter 5 has a flange ring section and an externally threaded pipe section. When in use, the externally threaded pipe section is inserted vertically upward into the first clamping component 3. At this time, the first clamping component 3 is not connected to the drive component 2, and the second clamping component 4 is connected to the drive component 2, so that the first clamping component 3 is in a released state and the second clamping component 4 is in a clamped state. When the first clamping component 3 and the second clamping component 4 are pushed relative to the clamping table 1, the first clamping component 3 is connected to the drive component 2, so that the first clamping component 3 clamps and positions the adapter 5 placed therein, and at the same time, another adapter 5 can be placed in the second clamping component 4, which is convenient for processing. After the processing is completed, the first clamping component 3 and the second clamping component 4 are reset, so that the first clamping component 3 is disconnected from the drive component 2, and the processed rotating head can be taken out. At the same time, the second clamping component 4 can clamp another adapter 5 for continuous clamping, processing and material removal.

[0033] In this embodiment, the driving component 2 is arranged on the clamping table 1, so that the first clamping component 3 and the second clamping component 4 can clamp and position the adapter 5 when they are respectively connected to the driving component 2. At the same time, when the first clamping component 3 and the second clamping component 4 are not connected to the driving component 2, the adapter 5 can be removed from the first clamping component 3 and the second clamping component 4 to facilitate continuous clamping processing and higher work efficiency.

[0034] like Figure 4 、 Figure 5 and Figure 8As shown, the structures of the first clamping assembly 3 and the second clamping assembly 4 are the same. The first clamping assembly 3 includes a sliding plate 311, a first clamping plate 312, a second clamping plate 313, a first guide column 314, a second guide column 315 and a tension spring 316. The sliding plate 311 is slidably arranged on the top of the clamping platform 1. The first clamping plate 312 and the second clamping plate 313 are slidably arranged on the sliding plate 311 toward or away from each other. A clamping opening 317 is provided on each of the first clamping plate 312 and the second clamping plate 313. The first clamping plate 312 and the second clamping plate 313 can be staggered to clamp the adapter 5 passing through the clamping opening 317. The first guide column 314 is fixedly arranged on the first clamping plate 312 along the longitudinal direction. The second guide column 315 is fixedly arranged on the first clamping plate 312 along the longitudinal direction. It is longitudinally fixedly arranged on the second clamping plate 313, the first guide column 314 passes through the sliding plate 311 and slides with it, the second guide column 315 passes through the sliding plate 311 and slides with it, the driving component 2 has a first guide surface and a second guide surface symmetrically arranged at the top of the clamping platform 1, the first guide surface and the second guide surface both have a transverse section 21, and a first inclined surface section 22 and a second inclined surface section 23 symmetrically arranged on both sides of the transverse section 21, the first guide column 314 slides with the first guide surface, the second guide column 315 slides with the second guide surface, the two ends of the tension spring 316 are fixedly connected to the first guide column 314 and the second guide column 315 respectively, and the second clamping component 4 slides with the second inclined surface section 23.

[0035] When the first and second clamping assemblies 31 and 31 are in a state of being rotated with each other, the first guide post 314 and the second guide post 315 can move closer to or away from each other by overcoming the tension of the tension spring 316, thereby making the first clamping assembly 3 and the second clamping assembly 4 slidingly arranged at the top of the sliding plate 311 move toward or away from each other. At the same time, after the adapter 5 passes through the clamping opening 317 of the first clamping plate 312 and the second clamping plate 313, the first clamping plate 312 and the second clamping plate 313 are intertwined to form a clamping force on the adapter 5, and the second clamping assembly 4 slides with the second inclined surface section 23, so that when the first clamping assembly 3 and the second clamping assembly 4 slide on the clamping platform 1, the clamping opening 317 of the first clamping assembly 3 and the second clamping assembly 4 can be opened or closed, thereby facilitating continuous loading, clamping and unloading.

[0036] like Figure 4 and Figure 5 As shown, the first clamping assembly 3 further includes a roller 32 , which is rotatably disposed at the bottom ends of the first guide column 314 and the second guide column 315 , and the roller 32 is in rolling engagement with the first guide surface and the second guide surface.

[0037] By coaxially rotatably arranging the roller 32 at the bottom ends of the first guide column 314 and the second guide column 315 , the friction between the first guide column 314 and the second guide column 315 and the first guide surface and the second guide surface is reduced, thereby improving the stability of the structure.

[0038] like Figure 9 and Figure 10 As shown, the clamping opening 317 has a V-shaped groove and a placement groove extending along the expansion direction of the V-shaped groove, and the width of the placement groove is greater than the diameter of the adapter 5.

[0039] Because the clamping opening 317 has a V-shaped groove and a placement groove extending along the expansion direction of the V-shaped groove, when the clamping opening 317 moves toward each other, the V-shaped grooves on the clamping opening 317 on the first clamping plate 312 and the second clamping opening 317 can move toward each other to position and clamp the adapter 5, thereby preventing self-rotation during processing of the adapter 5.

[0040] like Figure 9 and Figure 10 As shown, the first clamping assembly 3 also includes a first positioning plate 33 and a second positioning plate 34, and the first positioning plate 33 and the second positioning plate 34 are arranged at the top end of the sliding plate 311 towards each other or slidingly in back to back, and the first positioning plate 33 and the second positioning plate 34 are both provided with a avoidance opening for avoiding the adapter 5, and the first positioning plate 33 is also provided with a first clamping block 331, and the first clamping block 331 is provided with a first arc-shaped inclined groove 332 inclined downward on the side facing the rotating head, and the second positioning plate 34 is also provided with a second clamping block 341, and the second clamping block 341 is provided with a second arc-shaped inclined groove 342 inclined downward on the side facing the adapter 5, one end of the first positioning plate 33 is elastically connected to the first guide column 314, and one end of the second positioning plate 34 is elastically connected to the second guide column 315.

[0041] When the first guide post 314 and the second guide post 315 move toward or away from each other, the first guide post 314 can drive the first positioning plate 33 to slide on the sliding plate 311, and the second guide post 315 can drive the second positioning plate 34 to slide on the sliding plate 311, so that the first positioning plate 33 and the second positioning plate 34 slide toward or away from each other on the sliding plate 311, thereby causing the first clamping block 331 and the second clamping block 341 to move toward or away from each other. When the adapter 5 is clamped, the first arcuate bevel 332 of the first clamping block 331 and the second arcuate bevel 342 of the second clamping block 341 move toward each other to abut against the top edge of the flange ring section of the adapter 5. Under the action of the first arcuate bevel 332 and the second arcuate bevel 342, the adapter 5 stably abuts against the top end of the sliding plate 311 in the longitudinal direction to prevent the adapter 5 from sliding in the longitudinal direction during processing.

[0042] like Figure 10 As shown, the first clamping assembly 3 also includes a first elastic connector and a second elastic connector, the first elastic connector includes a first connecting head 351, a first spring 352 and a first limiting ring 353, the outer end of the first positioning plate 33 is provided with a first placement plate extending longitudinally, the first connecting head 351 is fixedly connected to the first guide column 314, one end of the first connecting head 351 is provided with a first sliding column 3511 that horizontally passes through the first placement plate and slides with it, the first spring 352 is sleeved on the first sliding column 3511, the first spring 352 is located between the first placement plate and the first connecting head 351, and the first limiting ring 353 is set at the first sliding column 3511 The outer end is located on the outer side of the first positioning plate; the second elastic connecting member includes a second connecting head 361, a second spring 362 and a second limiting ring 363, and the outer end of the second positioning plate 34 is provided with a second positioning plate extending in the longitudinal direction, the second connecting head 361 is fixedly connected to the second guide column 315, and the two ends of the second connecting head 361 are provided with a second sliding column 3611 that horizontally passes through the second positioning plate and slides with it, the second spring 362 is sleeved on the second sliding column 3611, and the second spring 362 is located between the second positioning plate and the second connecting head 361, and the second limiting ring 363 is arranged at the outer end of the second sliding column 3611 and is located on the outer side of the second positioning plate.

[0043] When the first guide post 314 slides, it can drive the first sliding post 3511 to slide on the first mounting plate through the first connecting head 351, and the first limiting ring 353 can prevent the first sliding post 3511 from detaching from the first mounting plate. The first positioning plate 33 overcomes the elastic force of the first spring 352 and drives the first clamping block 331 to elastically abut against the flange ring section of the adapter 5 in the radial direction. Similarly, when the second guide post 315 slides, it can drive the second sliding post 3611 to slide on the second mounting plate through the second connecting head 361, and the second limiting ring 363 can prevent the second sliding post 3611 from detaching from the second mounting plate. The second positioning plate 34 overcomes the elastic force of the second spring 362 and drives the second clamping block 341 to elastically abut against the flange ring section of the adapter 5 in the radial direction, thereby improving the clamping stability of the adapter 5.

[0044] like Figure 10 As shown, both sides of the bottom end of the first clamping plate 312 are provided with engaging strips 3121 extending along its sliding direction, and both sides of the top end of the second clamping plate 313 are provided with engaging grooves 3131 extending along its sliding direction, and the engaging strips 3121 and the engaging grooves 3131 are slidably matched.

[0045] By slidingly engaging the engaging strip 3121 of the first clamping plate 312 with the engaging groove 3131 of the second clamping plate 313 , when the first clamping plate 312 and the second clamping plate 313 move toward or away from each other, the clamping openings 317 of the first clamping plate 312 and the second clamping plate 313 can be retracted to clamp the adapter 5 .

[0046] like Figure 6 and Figure 7 As shown, the driving assembly 2 also includes two driving plates 24 sliding toward or away from each other on the clamping table 1, and a movable adjustment member for adjusting the distance between the two driving plates 24, the first guide surface and the second guide surface are respectively located on the back sides of the two driving plates 24, and the movable adjustment member is arranged on the clamping table 1 and connected to the driving plate 24.

[0047] The clamping state of the first clamping plate 312 and the second clamping plate 313 can be driven by the driving plate 24. At the same time, the distance between the two driving plates 24 can be adjusted by moving the adjusting member, thereby adjusting the diameter of the clamping opening 317 of the first clamping plate 312 and the second clamping plate 313 to facilitate clamping adapters 5 of different diameters.

[0048] like Figure 7 As shown, the movable adjustment member includes a first sliding block 251, a second sliding block 252, a bidirectional screw rod 253, a first connecting rod 254 and a second connecting rod 255. The first sliding block 251 and the second sliding block 252 are arranged on the clamping platform 1 to slide toward or away from each other along the sliding direction of the first clamping plate 312 and the second clamping plate 313. The bidirectional screw rod 253 is rotatably arranged on the clamping platform 1 and is threadedly connected to the first sliding block 251 and the second sliding block 252. The two ends of the first connecting rod 254 are rotatably connected to the driving plate 24 and the first sliding block 251 respectively, and the two ends of the second connecting rod 255 are rotatably connected to the driving plate 24 and the second sliding block 252 respectively.

[0049] When the distance between the two driving plates 24 is required, the bidirectional screw rod 253 is rotated so that the first sliding block 251 and the second sliding block 252 threadedly connected to the bidirectional screw rod 253 can move toward or away from each other, and then the first connecting rod 254 and the second connecting rod 255 can drive the driving plate 24 to slide on the clamping table 1, so that the distance between the two clamping tables 1 can be adjusted.

[0050] like Figure 8 As shown, the driving assembly 2 also includes a slide cylinder 26 and a connecting plate 27. The connecting plate 27 is fixedly connected to the first clamping assembly 3 and the second clamping assembly 4. The slide cylinder 26 is arranged on the clamping table 1, and the output end of the slide cylinder 26 is fixedly connected to the connecting plate 27.

[0051] By starting the slide cylinder 26, the output end of the slide cylinder 26 can drive the first clamping assembly 3 and the second clamping assembly 4 to slide synchronously on the clamping table 1 through the connecting plate 27, thereby facilitating continuous loading, clamping and unloading.

[0052] The above embodiments merely represent one or several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the spirit of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
