The base main body 11 is used for being mounted on an external frame. The track plate 12 is fixed on the base table main body 11 in a threaded manner, and the length of the track plate 12 is smaller than that of the base table main body 11. A locking plate 121 is convexly arranged on the end surface of the track plate 12, which faces away from the base table main body 11. The locking plate 121 is used for clamping and fixing the driving module 20. The track pressing plate 13 is an L-shaped metal plate, one end of which is abutted against the end of the track plate 12, and the other end of which is fixed to the base station main body 11 in a screwing manner, so that the purpose of fixing the track plate 12 is achieved. The fine adjustment assembly 14 includes a scale plate 141 disposed on an end surface of the track pressing plate 13 facing away from the track plate 12, a dial indicator 142 disposed on the scale plate 141, and an angle indicator 143 pivotally connected to the scale plate 141. The fine adjustment assembly 14 is used for fine adjustment in cooperation with the driving module 20.

The driving module 20 includes a headstock 21 disposed on one end of the track plate 12, a tailstock 22 disposed on the other end of the track plate 12, and two clamping mechanisms 23 disposed on opposite end surfaces of the headstock 21 and the tailstock 22, respectively.

The headgear 21 includes a headgear body 211 disposed at an end of the track plate 12, a headgear spindle 212 inserted in the headgear body 211, a headgear motor mount 213 disposed at an end of the headgear body 211 opposite the track plate 12, a headgear motor 214 secured to the headgear motor mount 213, the headgear motor 214 and the headgear spindle 212 connected by a set of headgear drive trains 30. And drives the headstock spindle 212 to rotate through the cooperation of the headstock motor 214 and the drive pulley set 30.

At least two headgear locking feet 215 are provided between the headgear body 211 and the track plate 12. The headgear locking feet 215 mate the fit between the headgear body 221 and the track plate 12. A headgear locking bar 216 projects from an end surface of the headgear body 221 remote from the headgear locking leg 215. The same purpose is to provide a tight fit between the head body 221 and the rail plate 12, and to fit the head locking foot 215, thereby preventing the head body 221 from wobbling after it is fitted to the rail plate 12.

A diamond conditioner 23 is provided on the end surface of the head body 211 adjacent the head locking bar 216. The diamond dresser 23 is used for dressing a machining tool easily.

The tailstock 22 includes a slide table 221 disposed at an end of the track plate 12 remote from the headstock 21, a pushing mechanism 222 disposed between the slide table 221 and the track plate 12, a tailstock body 223 disposed on the slide table 221, a tailstock spindle 224 inserted in the tailstock body 223, a tailstock motor support 225 disposed on an end surface of the tailstock body 224 facing away from the slide table 221, and a tailstock motor 226 disposed on the tailstock motor support 225.

It is contemplated to avoid slip caused by the lack of synchronization of the rotation speeds of the headstock motor 214 and the tailstock motor 226 during rotation. Therefore, the same control unit, such as a PLC, is used between the headstock motor 214 and the tailstock motor 226, and even if the tailstock motor 226 follows the headstock motor 214, when the headstock motor 214 rotates, the tailstock motor 226 follows the headstock motor, so that a motor with a higher rotation speed can follow a motor with a lower rotation speed. At the same time, the 224 motor will receive 214 motor related data feedback to make fine speed corrections to ensure that the headstock motor 214 and the tailstock motor 226 rotate at the same speed.

At least four sliding blocks 2211 are arranged between the sliding table 221 and the track plate 12, and two guide rails 2212 are arranged between the four sliding blocks 2211 and the track plate 12. The sliding table 221 slides on the two guide rails 2212 through the sliding block 2211, so as to adjust the spacing distance between the tailstock 22 and the headstock 21.

The pushing mechanism 222 includes a single lug 2221 connected to the track plate 12, two lugs 2222 pivotally connected to the single lug 2221, and an air cylinder 2223 disposed on the two lugs 2222. The output end of the cylinder 2223 is connected with the end surface of the sliding table 221 facing the track plate 12. The cylinder 2223 drives the sliding table 221 to slide along the guide rail 2212.

The clamping mechanism 23 includes a clamp seat 231 sleeved on the headstock spindle 212 and the tailstock spindle 224, a clamping jaw 232 disposed on an end surface of the clamp seat 231, and a thimble 233 disposed on a central region of the headstock spindle 212 and the tailstock spindle 224.

The fixture mount 231 follows the headstock spindle 212 and tailstock spindle 224 for rotation. The clamping jaw 232 includes two ear seats 2321 spaced apart from each other on the clamp seat 231, two piston rods 2322 inserted into the clamp seat 231 and penetrating through the ear seats 2321, two connecting seats 2323 respectively embedded in the ear seats 2321 on two sides, two pivoting blocks 2324 pivoted to two ends of the connecting seat 2323, and a connecting bridge 2325 connected to the pivoting blocks 2324 on two sides.

Two clamping blocks 2326 are arranged on the opposite end faces of the connecting bridges 2325, and a buffer block 2327 is arranged on the opposite end faces of the two clamping blocks 2326. And the clamping blocks 2326 are detachable, so that the clamping blocks 2326 with different specifications can be replaced conveniently to adapt to the sizes of workpieces with different sizes. The buffer block 2327 is used for protecting the surface of the workpiece and avoiding damaging the surface of the workpiece during clamping.

The piston rod 2322 is driven through an oil passage provided in the jig seat 231. When the connecting device is used, the piston rod 2322 ejects the connecting seat 2323, so that the pivoting block 2324 pivoted with the connecting seat 2323 is turned over to drive the connecting bridge 2325 to turn over, and accordingly a workpiece is loosened. When the piston rod 2322 drives the connecting seat 2323 to move toward the end surface of the clamp seat 231, the workpiece is clamped.

The thimble 233 is used to push against the center points of the two ends of the workpiece, so as to further improve the stability during processing.

Compared with the prior art, the utility model provides a pair of head-tail frame double tops are two to drive workstation is through the design headstock 21 and tailstock 22 mutually support to synchronous the rotation, so that better cutting process. And the two clamping mechanisms 23 can greatly improve the rigidity of the workpiece. Compared with the conventional machine tool workbench, the equipment has higher cutting and machining efficiency and higher practicability.
