Description

Technical Field

[0001] The invention relates to the technical field of mechanical processing, in particular to a linked rolling processing device. Background Art

[0002] Rolling is a chipless process that applies a certain pressure to the surface of the workpiece to be processed through a certain form of rolling tool, causing a small amount of local plastic deformation on the surface, thereby achieving the purpose of changing the roughness of the surface to be processed. During rolling, in order to improve the rolling quality of the workpiece surface to be processed, multiple rolling is usually required, but the existing rolling processing device can only roll the surface of the workpiece to be processed once within one rotation stroke, and the rolling efficiency is low. Summary of the invention

[0003] In order to solve the problem of low rolling efficiency in the existing rolling processing device, the present invention provides a new linked rolling processing device.

[0004] The present invention is achieved by adopting the following technical solutions: A linked rolling processing device comprises a cylindrical connecting base, a radial synchronous adjustment mechanism, and four rolling mechanisms; The radial synchronous adjustment mechanism includes multiple gear shafts, four positioning bases, and a positioning pressure block. A lower annular groove is provided on the top surface of the connecting base. The top of the inner groove wall and the top of the outer groove wall of the lower annular groove are circumferentially evenly provided with multiple lower semicircular holes. The positioning pressure block is pressed and fixed on the connecting base. An upper annular groove matching the lower annular groove is provided on the bottom surface of the positioning pressure block. The top of the inner groove wall and the top of the outer groove wall of the upper annular groove are circumferentially evenly provided with multiple upper semicircular holes matching the lower semicircular holes. The upper semicircular holes and the corresponding lower semicircular holes form a rotating hole. Multiple gear shafts are arranged along the radial direction of the connecting base and the two end portions of the multiple gear shafts The gear shafts are rotatably connected to the corresponding rotating holes, and an end face of at least one gear shaft away from the center of the connecting base is provided with an inner hexagonal hole. The middle parts of the multiple gear shafts are sleeved with small bevel gears. A large bevel gear meshing with the multiple small bevel gears is coaxially arranged in the upper annular groove. A cross slide is provided on the top of the positioning block. The cross slide is formed by a cross arrangement of two strip grooves. The four positioning bases are radially slidably connected to the cross slide. An Archimedean spiral slide is coaxially fixed on the non-bevel gear surface of the large bevel gear. The bottom surface of each positioning base is provided with a plurality of radially distributed sliders adapted to the Archimedean spiral slide. Each rolling mechanism comprises a rolling seat, and four rolling seats are respectively fixed on four positioning bases. A roller is rotatably mounted on each rolling seat, and the four rollers are adapted to the inner cylindrical surface or the outer cylindrical surface to be processed.

[0005] When in use, the connecting base is fixed on the machine tool spindle (how to fix the connecting base on the machine tool spindle belongs to the conventional technical means of technical personnel in this field, that is, the connecting base can be heat-fitted on the machine tool spindle after the center hole of the connecting base is opened, or the connecting base can be fixed on the machine tool spindle by a clamping tool). Since there are four rolling columns on the device, when rolling the inner cylindrical surface or outer cylindrical surface to be processed, the machine tool spindle rotates one circle, which is equivalent to rolling the inner cylindrical surface or outer cylindrical surface to be processed four times, and the rolling efficiency is greatly improved; at the same time, the device cleverly adopts a radial synchronous adjustment mechanism, and a hexagonal wrench is inserted into the inner hexagonal hole of one of the gear shafts. When the hexagonal wrench is turned, the corresponding gear shaft rotates, and the corresponding small bevel gear rotates, thereby driving the large bevel gear to rotate. The rotation of the large bevel gear drives the Archimedean spiral slide rail to rotate, and then drives the four positioning bases to move radially synchronously, so that the device can roll inner cylindrical surfaces or outer cylindrical surfaces of different diameters.

[0006] Furthermore, a reversing base is fixed between each rolling seat and the corresponding positioning base, and the reversing base and the positioning base are fixedly connected by fixing bolts, and the reversing base can still be fixed to the positioning base by fixing bolts after reversing in the radial direction of the connecting base. After the four reversing bases are all reversed, the four rollers are adapted to the outer cylindrical surface or inner cylindrical surface to be processed instead of being adapted to the inner cylindrical surface or the outer cylindrical surface to be processed before reversing. The design of the reversing base structure increases the processing application range of the device, so that the rolling processing device can process both the inner cylindrical surface to be processed and the outer cylindrical surface to be processed. When reversing, it is only necessary to remove the fixing bolts, then reverse the reversing base, and finally fix the positioning base and the reversing base again by fixing bolts.

[0007] Furthermore, the positioning base is in an inverted T shape as a whole, and the cross section of each strip groove is an inverted T shape that matches the positioning base. The structure in which the positioning base is radially slidably connected to the cross groove is specific, simple and easy to implement.

[0008] Furthermore, limit blocks are provided at both ends of the radial direction of the top surface of the positioning base, the bottom end of the reversing base is clamped between the two limit blocks and both ends of the reversing base in the radial direction are fixed to the middle part of the positioning base by fixing bolts, which is convenient for quickly positioning the position of the reversing base during reversing installation.

[0009] Furthermore, a rotating base is provided between each rolling seat and each reversing base. The reversing base is U-shaped as a whole. Both side arms of each reversing base are arranged along the radial direction of the connecting base. Both side arms of each reversing base are provided with a reversing center hole and a reversing positioning hole. The bottom of the steering base is a steering block placed between the two side arms of the reversing base. The steering block is provided with a steering center hole adapted to the reversing center hole and a plurality of steering positioning holes uniformly distributed in the circumference and adapted to the reversing positioning holes. The reversing center hole and the reversing center hole are adapted with a center bolt and a center nut. The reversing positioning hole and the steering positioning hole are adapted with a positioning bolt and a positioning nut. When the chamfered surface needs to be rolled, the rolling mechanism needs to adjust the angle, loosen the center nut, remove the positioning bolt and the positioning nut, rotate the rotating base to a suitable position and make the position of a certain steering positioning hole adapted to the reversing positioning hole, install and fix the positioning bolt and the positioning nut, tighten the center nut, and complete the angle rotation of the rolling mechanism.

[0010] Furthermore, the positioning block can be removably pressed onto the connecting base. When a conical surface needs to be rolled, the three positioning bases and the corresponding reversing base, steering base, and rolling mechanism are removed, and one positioning base and the corresponding reversing base, steering base, and rolling mechanism are used to roll the surface to be processed, thereby widening the scope of application of the device.

[0011] Furthermore, the top of the rotating base is a fan-shaped block, which is a 1 / 4 disk. A rotating through groove with an inverted T-shaped cross section is provided on the arc surface of the fan-shaped block. Multiple adjustment holes evenly distributed circumferentially are provided on the groove walls on both sides of the rotating through groove. The bottom of the rolling seat is an inverted T-shaped block adapted to the rotating through groove. The inverted T-shaped block is provided with two rolling positioning holes adapted to the adjustment holes. The two rolling positioning holes and the adjustment holes are adapted with adjusting bolts and adjusting nuts, which facilitate better adjustment of the angle of the rolling mechanism so that it can better adapt to the angle of the surface to be processed.

[0012] Furthermore, a C-shaped rolling groove is provided on the top of the rolling seat, and the roller is rollingly installed in the C-shaped rolling groove. One end of the C-shaped rolling groove is open and a detachable sealing cover is provided at the opening to facilitate the removal and replacement of the roller.

[0013] Furthermore, a central connecting hole adapted to the machine tool spindle is provided in the center of the connecting base and the positioning block, so that the rolling device can be clamped on the tool handle adapted to the machine tool spindle through the central connecting hole during use.

[0014] Furthermore, there are four gear shafts, and the end faces of the four gear shafts away from the center of the connecting base are all provided with hexagonal holes to avoid the situation where the hexagonal hole is turned to an angle that is inconvenient for the operator to use a hexagonal wrench to rotate as the machine tool spindle rotates when there is only one hexagonal hole.

[0015] The beneficial effects produced by the present invention are as follows: the linked rolling device described in the present invention improves the rolling efficiency through four rolling mechanisms, realizes the rolling of the inner cylindrical surface and the outer cylindrical surface to be processed through the reversing mechanism, and at the same time realizes the rolling of the inner cylindrical surface or the outer cylindrical surface to be processed of different diameters through the radial synchronous adjustment mechanism. In addition, the adjustment of the rolling angle is realized through the cooperation of the steering mechanism, the rolling mechanism and the reversing mechanism. BRIEF DESCRIPTION OF THE DRAWINGS
