[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] See also Figure 1 In this embodiment, a surface grinder for bent shaft parts includes a roller frame 1 and a side frame 2 located at the back and tail end of the roller frame 1. The table top of the roller frame 1 is divided into two, and multiple wheel groups are installed on the opposite sides of the two tables. A carrier 4 attached to the wheel group is placed between the two tables. A mobile positioning mechanism 5 is installed in the middle of the roller frame 1, and a lifting mechanism 6 is installed on the side frame 2. The movable end of the lifting mechanism 6 is installed with a grinding mechanism 3 located above the carrier 4.

[0025] In the above mechanism, the carrier that holds the parts is placed on the roller frame, the carrier can be moved by the wheel group, and the mobile positioning mechanism can move the carrier until it moves to the specified position to complete the positioning of the carrier. Then the lifting mechanism drives the grinding mechanism to move down to the appropriate position. During the grinding process of the parts, the grinding mechanism can also adjust the grinding position according to needs, thereby realizing automation, which can effectively reduce the errors caused by processing. At the same time, the carrier is flexible and can be replaced. After the processing is completed, it can be connected to the processing, avoiding the time wasted waiting for unloading and loading, and thus can effectively improve the processing efficiency.

[0026] Further, we can know that Figure 4-5 The mobile positioning mechanism 5 is divided into a pushing end and a positioning part. The pushing end moves the carrier to walk on the roller frame until it is located above the positioning part, and the positioning part fixes the carrier.

[0027] Among them, the pushing end includes a bottom plate 501 fixed under the roller frame 1, a side shift screw device 502 is installed on the back of the bottom plate 501, and an opening is opened on the bottom plate 501, and a side shift plate 503 is slidably connected to the front of the bottom plate 501 and fixed to the moving end of the side shift screw device 502 through the opening. The side shift plate 503 also has an opening, and there is a gap between the side shift plate 503 and the bottom plate 501. An upward push cylinder 504 is installed on the inner side of the opening of the side shift plate 503. The piston rod of 504 is fixed with an upper push plate 505 which is slidingly connected to the side shift plate 503. Two limit blocks 506 are fixed to the plate surface of the upper push plate 505. The front of the upper push plate 505 is slidingly connected to two counter-sliding plates 507. The left counter-sliding plate 507 is located between the two limit blocks 506. A chuck 508 is fixed on the top of the counter-sliding plate 507. Two counter-sliding cylinders 509 are installed on the left counter-sliding plate 507. The piston rod of the counter-sliding cylinder 509 is fixedly connected to the right counter-sliding plate 507.

[0028] As mentioned above, the push cylinder can drive the two shift plates to move relative to each other or move away from each other, so that the two chucks can be opened and located on both sides below the carrier, and then the upper push cylinder drives the upper push plate to push up, so that the carrier can be located between the two chucks, and the push cylinder can retract to clamp the bottom of the carrier, and then the side shift screw device drives the side shift plate to move, so that the chuck can drive the carrier to move on the roller frame until it moves to the specified position and stops, and at the same time it can also play the role of limiting and positioning the carrier;

[0029] And when the parts on the carrier are processed, it can be driven to move to the tail end of the roller frame, and then quickly reset to the head end of the roller frame, and repeat the above operation with the next set of prepared carriers, thus achieving continuous processing and polishing to improve processing efficiency.

[0030] The positioning unit also includes an upper cylinder 7 fixed to the two surfaces of the roller frame 1. Two guide tubes 8 are fixed to each surface, one on each side of the upper cylinder 7. The piston rod of the upper cylinder 7 is fixed to an electromagnetic suction plate 9 connected to the telescopic ends of the two guide tubes 8. When the pusher moves the carrier above the two electromagnetic suction plates, the upper cylinder, guided by the guide tubes, drives the electromagnetic suction plates upward and abuts against the bottom of the carrier. The electromagnetic suction plates then operate to attract and position the carrier, while also improving the firmness of the carrier's positioning.

[0031] like Figure 2-3The lifting mechanism 6 includes a fixed plate 602 fixed to the front of the side frame 2. The fixed plate 602 also has an opening, and a lifting cylinder 601 is installed on the back of the fixed plate 602. The piston rod of the lifting cylinder 601 passes through the opening and fixes a lifting plate 603 that slides with the fixed plate 602. The grinding mechanism 3 is mounted on the lifting plate 603. The operation of the lifting cylinder drives the lifting plate to move up and down on the fixed plate, so the grinding mechanism will also rise and fall with the lifting plate, so that the grinding mechanism can be lowered to the appropriate grinding point according to the grinding requirements.

[0032] Two sets of sprockets 604 are fixed to the top of the side frame 2, each set of sprockets 604 consisting of two sprockets. Two guide rods 607 are fixed to the inner bottom wall of the side frame 2, along with a counterweight 606 that slides between the two guide rods 607. Two chains 605 are fixed to the top of the counterweight 606, each meshing with the two sets of sprockets 604 and fixed to the lifting plate 603. A stopper is fixed to the surface of the fixed plate 602, positioned above the lifting plate 603. When the lifting mechanism drives the grinding mechanism to reset, the counterweight, guided by the guide rods and in conjunction with the sprocket chain, pulls up the lifting plate, thereby reducing the load on the lifting cylinder after it resets, thereby effectively extending the service life of the lifting cylinder.

[0033] In addition, the grinding mechanism 3 includes a transverse screw assembly 301 fixed to a lifting plate 603. The left end of the transverse screw assembly 301 extends from the lifting plate 603. The bottom movable end of the transverse screw assembly 301 is fixed to the transverse plate 302. The bottom of the transverse plate 302 is mounted with a longitudinal screw assembly 303. The movable end of the longitudinal screw assembly 303 is fixed to the grinding device 304. During the grinding process, the height of the grinding device can be adjusted through the lifting mechanism. At the same time, the transverse and longitudinal screw assemblies can drive the grinding device to move left and right and forward and backward to adjust the grinding position, thereby improving the grinding flexibility.

[0034] The working principle of the above embodiment is:

[0035] The upper cylinder drives the electromagnetic suction plate to move up, and it is attached to and adsorbed with the bottom of the carrier. Then the lifting cylinder is operated to drive the grinding device to descend to the appropriate height to grind the parts. During the grinding process, both the transverse screw device and the longitudinal screw device can drive the grinding device to adjust the grinding position, thereby improving the flexibility of grinding. At the same time, automation can also reduce the error of grinding parts and improve the quality of products.

[0036] At the same time, when the grinding is completed, the electromagnetic suction plate stops running, the upper cylinder retreats, the side-moving screw device runs, and the carrier is moved to the tail end through the chuck, and then the side-moving screw device is reset. The above operation is repeated to move the carrier at the head end to the top of the electromagnetic suction plate again, so that continuous processing can be achieved, which can save a lot of time and improve processing efficiency.
