Description

Technical Field

[0001] The utility model relates to the field of ball screw nut processing jigs, in particular to a ball screw nut multi-station production jig. Background Art

[0002] In the current ball screw nut processing process, the traditional single-station processing method has many shortcomings. For example, each processing step needs to be carried out on a separate device, and frequent clamping and positioning not only consumes a lot of time, but also easily introduces processing errors, affecting the accuracy and quality consistency of the product. In order to improve the processing efficiency and quality of ball screw nuts, multi-station workbenches have been widely used in the processing process.

[0003] However, in the processing of ball screw nuts, the nut blank is usually installed on the surface of the rotary table, and then the rotary table is clamped on the surface of the base, and then the base is drilled and fixed to the multi-station workbench with bolts. First, the bolt fixing needs to tighten or loosen the bolts one by one, which is cumbersome and consumes a lot of time and manpower. In addition, this inconvenience is particularly prominent when the rotary table needs to be replaced or repaired and maintained, which seriously affects the production efficiency. The bolt connection is prone to loosening after long-term use, thereby affecting the positioning accuracy of the rotary table. Even if strict calibration is performed during installation, it is difficult to avoid the accuracy deviation caused by loose bolts. When the bolt fixing method is subjected to large cutting forces and vibrations, deformation or fatigue damage of the connection parts is prone to occur, affecting the stability of the entire workbench system.

[0004] Therefore, a multi-station production jig for ball screw nut is proposed. Utility Model Content

[0005] In view of the above problems, the utility model provides a multi-station production fixture for ball screw nuts to solve the problems raised in the above background technology.

[0006] The technical solution of the utility model is:

[0007] A multi-station production jig for ball screw nuts comprises a processing table, a top surface of which is symmetrically provided with a plurality of equally spaced bases, a baffle fixedly connected to the middle of the top surface of the processing table, a bottom surface of the base fixedly connected to an elliptical bolt, two side walls of the processing table are provided with a plurality of equally spaced clamps, opposite surfaces of the clamps and the processing table are provided with sockets, the elliptical bolt is located between two opposite sockets and is clamped with the sockets.

[0008] During work, first install the splint on the two side walls of the processing table in turn, and form an opening for inserting the elliptical bolt by the sockets on the side walls of the splint and the side walls of the processing table. Then, fix the splint to the processing table with bolts through the fastening port, and then insert the elliptical bolt into the inner wall of the socket. The socket in this state will interfere with the surface of the elliptical bolt, thereby forming a rotation restriction, thereby maintaining the stability of the base. Then, place the rotary worktable on the inner wall of the installation port, and then put the nut into the rotary worktable for preparation for processing.

[0009] In a further technical solution, a mounting opening is provided on the top surface of the base, a rotating worktable is provided on the inner wall of the mounting opening, and a chip guide opening communicating with the rotating worktable is provided at the bottom end of the elliptical bolt.

[0010] Through the above technical solution, it is convenient for the chips generated during the processing of the nut to fall out of the chip guide port smoothly from the rotating worktable.

[0011] In a further technical solution, both ends of the processing table are detachably connected to bearing support tables, and the outer surface of the bottom end of the bearing support table is fixedly connected to a support seat.

[0012] Through the above technical solution, the processing table can be supported for use conveniently, and when the processing table needs to be flipped, the bearing support table can be connected to an external motor for flipping.

[0013] In a further technical solution, a slide seat is fixedly connected between the two support seats, a slide table is arranged on the bottom surface of the slide seat, and the slide seat slides on the top surface of the slide table.

[0014] Through the above technical solution, it is convenient to move the slide to adjust the position of the nut on the surface of the processing table, which is beneficial to the efficiency of multi-station processing.

[0015] In a further technical solution, the bottom surfaces at both ends of the processing table are fixedly connected with protrusions, and the surfaces of the protrusions and the processing table are provided with reserved holes. The protrusions and the processing table are detachably connected by bolts passing through the reserved holes, and the processing table is connected to the bearing support platform through the reserved holes on the surface of the protrusions and the bolts.

[0016] The above technical solution makes it easy to install the processing table.

[0017] In a further technical solution, a fastening opening is provided on the side wall of the clamping plate, and the clamping plate is connected to the processing table by bolts passing through the fastening opening.

[0018] The above technical solution makes it easy to install the splint.

[0019] Compared with the prior art, the utility model has the following beneficial effects:

[0020] The use of the oval bolt and the socket for matching connection allows the base to be quickly installed and disassembled. Compared with the existing technology, there is no need to process the bolts one by one, saving a lot of time and manpower. In addition, the oval bolt is oval in shape and can fit tightly with the socket to provide more stable positioning, reduce the precision deviation caused by loose bolts, and improve the processing accuracy of the ball screw nut. In addition, the clamping method can make the base more evenly stressed on the surface of the processing table. When subjected to cutting force and vibration, it is not easy to have local deformation or fatigue damage, thereby enhancing stability, better resisting vibration during processing, and reducing the impact of vibration on processing accuracy and surface quality.

[0032] During operation, first install the splint 6 on the two side walls of the processing table 4 in turn, and form an opening for inserting the elliptical bolt 8 by the socket 7 on the side wall of the splint 6 and the socket 7 on the side wall of the processing table 4. Then, fix the splint 6 to the processing table 4 with bolts passing through the fastening port 12, and then insert the elliptical bolt 8 into the inner wall of the socket 7. In this state, the socket 7 will interfere with the surface of the elliptical bolt 8, thereby forming a rotation restriction, thereby maintaining the placement stability of the base 9. Then, place the rotating workbench 11 on the inner wall of the installation port 10, and then put the nut into the rotating workbench 11 for preparation for processing.

[0033] See also Figure 1 and Figure 3 The top surface of the base 9 is provided with a mounting opening 10 , the inner wall of the mounting opening 10 is provided with a rotating worktable 11 , and the bottom end of the elliptical bolt 8 is provided with a chip guide opening 81 communicating with the rotating worktable 11 .

[0034] This facilitates the chips generated during the processing of the nut to smoothly fall out of the chip guide opening 81 from the rotary worktable 11 .

In this state, the socket 7 will interfere with the surface of the elliptical bolt 8, thereby forming a rotation restriction, thereby maintaining the placement stability of the base 9, and then place the rotating worktable 11 on the inner wall of the installation opening 10, and then put the nut into the rotating worktable 11 for preparation for processing. After each completion, the processing table 4 can be rotated so that the processing table 4 rotates between the two bearing support platforms 3. This method can directly flip the processing table 4, which can facilitate direct unloading. In summary, the base 9 with the rotating worktable 11 is directly connected to the socket 7 through the elliptical bolt 8. The inner wall uses an elliptical bolt 8 and a socket 7 to cooperate with each other, so that the base 9 can be quickly installed and disassembled. Compared with the prior art, there is no need to process the bolts one by one, which saves a lot of time and manpower. In addition, the elliptical bolt 8 is elliptical and can fit tightly with the socket 7 to provide more stable positioning, reduce the precision deviation caused by the loosening of the bolts, and improve the processing accuracy of the ball screw nut. In addition, the clamping method can make the base 9 more evenly stressed on the surface of the processing table 4, and it is not easy to have local deformation or fatigue damage when subjected to cutting force and vibration, thereby enhancing stability, better resisting vibration during processing, and reducing the influence of vibration on processing accuracy and surface quality.
