DETAILED DESCRIPTION

[0016] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0017] The present invention discloses a cylindrical part finishing equipment, which performs finishing on the height, flatness and parallelism of the cylindrical parts after rolling. The specific structure is as follows: Figure 1 As shown, it includes a feeding component 1, a stamping component 2, a finishing component 3, a buffer unloading component 4 and a control component 5, wherein the feeding component realizes the loading of cylindrical parts one by one by means of vibration, and the cylindrical parts are in a vertical state during the loading process, so as to facilitate the subsequent stamping process, the stamping component is a CNC punch press, which is used to generate downward stamping force, the finishing component is installed on the working table of the stamping component, and a turntable is used to realize continuous feeding processing, and the pressure block cooperates with the limiter and other structures to realize high-precision processing of the parts, ensuring that the height of the processed parts, the flatness of the end face and the parallelism of the two ends meet the requirements, the buffer unloading component adopts an unloading turntable with a multi-stage unloading track to realize unloading, and the control component realizes the automatic control of the entire equipment, Specifically, the loading assembly includes a machine base 11, a vibration plate 12, a spiral loading track 13, and a feeding track 14. The vibration plate is installed on the machine base through a lifting and adjusting assembly 15. The spiral loading track is arranged inside the vibration plate so that the parts can be loaded one by one. The feeding track is fixed to a mounting bracket 17 on the side of the work table of the stamping assembly through a straight vibrator 16. One end of the feeding track is connected to the spiral loading track so that the parts can enter the feeding track one by one and be transmitted forward through the control of the straight vibrator. The other end of the feeding track extends to the finishing assembly to deliver the parts to the finishing assembly.

[0018] The punching assembly is a CNC punching machine, which has a workbench 21, a punch 22 located above the workbench, and a hydraulic drive member for driving the punch to move up and down.

[0019] The finishing assembly realizes the precision machining of parts, and its structure is as follows Figure 2~3 As shown, it includes a turntable 31 and a support seat 32 installed on the work table, an arc-shaped material baffle plate 33 fixed on the surface of the support seat, a pressure block 35 connected to the punch through a mounting plate 34, and a limiter 36 arranged between the support seat and the mounting plate, wherein the turntable is driven to rotate by a servo motor (not shown) below, and arc-shaped grooves 37 for accommodating cylindrical parts are arranged at equal intervals around the turntable. The support seat is an arc-shaped structure, which is located below the side of the turntable. After the cylindrical parts enter the arc-shaped grooves from the feeding track, they are lifted from below by the support seat to prevent the parts from falling downward. The arc-shaped surface of the arc-shaped material baffle plate fits the outer side surface of the turntable, and the cylindrical parts entering the arc-shaped grooves are limited laterally. Through the arc-shaped grooves, the arc-shaped material baffle plate and the support seat limit the internal cylindrical parts in the radial direction to avoid displacement during stamping and cause processing errors.

[0020] In order to ensure that the parts enter the arc groove accurately during use, the end of the feeding track is set on the surface of the support seat and fits with the side wall of the turntable, so that when the arc groove of the turntable is facing the feeding track, the parts can be directly pushed into the arc groove. In order to achieve precise control, a detection head 6 is also provided on the workbench. The detection head is facing the fitting part of the feeding track and the turntable to detect whether the cylindrical parts enter the arc groove. Only when the parts enter the arc groove, the control component controls the servo motor to drive the turntable to rotate one station, so that the next empty arc groove faces the feeding track.

[0021] The pressing block is fixed to the punch through a mounting plate, and the outer diameter of the pressing block is much larger than the outer diameter of the cylindrical part. When processing cylindrical parts of different diameters, there is no need to replace the pressing block additionally, and only the corresponding turntable needs to be replaced, thereby improving the compatibility of the pressing block.

[0022] The setting of the limit member can effectively control the downward stroke of the pressing block. The limit member includes an upper limit column 361 fixed on the back of the mounting plate and a lower limit column 362 fixed on the surface of the support seat. The upper and lower limit columns are relatively arranged. The upper limit column moves downward with the pressing block. When it abuts against the lower limit column, the pressing block cannot continue to move downward, thereby controlling the downward stroke of the pressing block. When in use, the stroke can be adjusted by adjusting the size of the lower limit column, thereby adjusting the height size of the cylindrical part after processing. At the same time, by controlling the flatness of the lower end face of the pressing block and the parallelism of the pressing block and the support seat, the flatness of the end face of the cylindrical part after processing and the parallelism of the two ends can be controlled, thereby realizing synchronous precision processing of the three parameters.

[0023] The structure of the buffer unloading component is as follows: Figure 4As shown, it includes a discharge turntable 41 and a multi-stage discharge track, wherein the discharge turntable is driven to rotate by a motor 42 at the bottom, and side baffles 43 are arranged around the discharge turntable to prevent parts from flying out, and a rubber buffer layer is arranged on the surface, and a discharge port 44 is opened on the side baffles. At the same time, a guide baffle 45 extending to the discharge port is arranged in the discharge turntable. The rotating discharge turntable can prevent the fallen parts from piling up, and rotating them to disperse them can effectively avoid the friction caused by the accumulation, and the coordinated guide baffles can make the parts in the discharge turntable fall accurately from the discharge port.

[0024] The multi-stage unloading track includes a first unloading track 46 and a second unloading track 47, wherein the first unloading track is inclined, and the upper end extends to the lower side of the turntable and is located at the end of the support seat to accurately catch the cylindrical parts dropped from the turntable, and the lower end of the first unloading track extends to the unloading turntable, so that the cylindrical parts fall into the unloading turntable for deceleration and buffering, and the second unloading track is also inclined, and its upper end is located at the unloading port, and the surface of the track is provided with multiple groups of buffer baffles 48 with alternating inclined layouts, and the surface of the buffer baffles is provided with a buffer layer, and the alternating buffer baffles can effectively prevent parts from rolling directly from the second unloading track, but instead roll down alternately to achieve a further buffering effect, which can effectively avoid collisions during unloading and affect product quality.

[0025] The control component is connected with the servo motor, the motor, the CNC punching machine and the detection probe to realize the corresponding automatic detection control.

[0026] The technical contents and technical features of the present invention have been disclosed as above. However, those skilled in the art may still make various substitutions and modifications based on the teachings and disclosures of the present invention without departing from the spirit of the present invention.
