Description

Technical Field

[0001] This utility model relates to the field of rubber ring processing technology, specifically a rubber ring flash removal device. Background Technology

[0002] Rubber rings, especially rubber O-rings, require compression molding and vulcanization under pressure in a mold during production. To prevent insufficient rubber, the rubber material filling the mold cavity must maintain a certain amount of interference. Excess rubber material overflowing the mold cavity forms flash. Rubber O-rings must be trimmed to obtain a product with a perfect appearance.

[0003] Traditional trimming processes mainly rely on manual hand-held cutting tools or stamping dies for trimming. However, manual trimming is time-consuming, inefficient, and prone to incomplete trimming. Furthermore, stamping dies need to be individually molded for different sizes of rubber rings, and low positioning accuracy can lead to uneven cuts and reduced product quality. Therefore, we provide a rubber ring burr trimming device. Utility Model Content

[0004] The purpose of this invention is to provide a rubber ring flash trimming device to solve the problems mentioned in the background art.

[0005] This utility model can be achieved through the following technical solution: a rubber ring flash removal device, including a base plate and a rotating disk rotatably mounted at the center of the base plate. The top of the rotating disk is fixed with a positioning mold for carrying the rubber ring. The outer side of the rotating disk is provided with two clamping components that press the rubber ring onto the positioning mold and a position adjustment component for adjusting the position of the cutter to remove the flash on the inner and outer sides of the rubber ring. The two clamping components and the position adjustment component are evenly distributed around the rotating disk at equal angles.

[0006] A further technical improvement of this utility model is that: the top of the rotating disk is provided with a positioning transmission pin and an adsorption magnetic ring is embedded therein, and the bottom of the positioning mold is provided with a positioning hole that cooperates with the positioning transmission pin and is fixed by magnetic attraction through the adsorption magnetic ring.

[0007] A further technical improvement of this utility model is that: the pressing assembly includes a cover fixedly connected to the base plate, a rotary cylinder is fixed inside the cover, and a lifting shaft is installed through the top of the cover for lifting and rotating, and the lifting shaft and the rotary cylinder are slidably engaged by a spline. A connecting rod is horizontally fixed on the lifting shaft, and a mounting rod is vertically fixed at the end of the connecting rod. A buffer head is elastically connected to the bottom of the mounting rod via a spring, and a pressure wheel is rotatably mounted on the buffer head.

[0008] A further technical improvement of this utility model is that a corrugated lifting groove is opened on the side wall of the through hole at the top of the cover, and rollers are symmetrically installed on the outside of the lifting shaft. The rollers and the lifting groove roll in cooperation, and the two rollers are simultaneously at the crest or trough of the lifting groove.

[0009] A further technical improvement of this utility model is that: the position adjustment component includes a vertical mounting plate fixed to the base plate, a telescopic cylinder is mounted on the vertical mounting plate, the output end of the telescopic cylinder is connected to a slider, a threaded adjustment unit is fixed on the slider, a tool holder is fixedly connected to the output end of the threaded adjustment unit, and an outer cutting blade and an inner cutting blade are fixed on the tool holder.

[0010] A further technical improvement of this utility model is that the distance between the outer cutting blade and the inner cutting blade is adjustable, a ruler is attached to the top of the blade holder, and the inner cutting blade is slidably positioned by the ruler.

[0011] A further technical improvement of this utility model is that the transmission structure of the thread adjustment unit is exactly the same as that of the micrometer.

[0012] A further technical improvement of this utility model is that: the substrate is reserved with multiple sets of fastening threaded holes for adjusting the installation position of the clamping component and the position adjustment component when adapting to positioning molds of different specifications.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. This utility model achieves automatic trimming of burrs by using a motor-driven rotating disk to rotate the positioning mold, which, in conjunction with a fixed blade, greatly shortens the time for a single operation. At the same time, the rotating cylinder of the clamping component controls the lifting and lowering of the clamping wheel through a corrugated lifting groove, achieving rapid clamping / releasing of the rubber ring, reducing auxiliary time, and thus greatly improving the efficiency of burr trimming.

[0014] 2. The positioning mold of this utility model can be quickly assembled and disassembled by magnetic attraction and positioning pin. The base plate has multiple sets of threaded holes, which can flexibly adjust the installation position of the clamping component and the position adjustment component to adapt to rubber rings of different sizes, thus avoiding the cost of repeated mold opening. The rotary cutting method keeps the blade and the flash at a constant contact angle, and the cut flatness is better than the stamping process. The annular bearing groove of the positioning mold cooperates with the clamping component to ensure that the rubber ring is centered and positioned, avoiding swaying during rotation.

An adsorption magnetic ring 302 is embedded in the top of the rotating disk 3. A positioning hole 402 that cooperates with the positioning transmission pin 301 is provided at the bottom center of the positioning mold 4. An annular bearing groove 401 is provided at the top of the positioning mold 4. The adsorption magnetic ring 302 is used to adsorb the positioning mold 4, so that it is adsorbed and fixed on the top of the rotating disk 3 and will not jump.

[0021] The clamping assembly 5 includes a base plate fixed to the base plate 2, a cover 501 fixed on the base plate, a rotary cylinder 502 fixedly installed inside the cover 501, and a lifting shaft 503 rotatably installed through the top of the cover 501. The bottom of the lifting shaft 503 is provided with a spline groove, and a spline 504 that mates with the spline groove is fixed at the output end of the rotary cylinder 502. A lifting groove 512 is opened on the side wall of the through hole at the top of the cover 501. The lifting groove 512 has a corrugated structure. Rollers 505 are symmetrically rotatably installed on the outside of the lifting shaft 503, and the two rollers 505 are simultaneously at the crest or trough of the lifting groove 512. A connecting rod 506 is fixedly and horizontally mounted on the top of the lifting shaft 503. An installation rod 507 is vertically fixed to the end of the connecting rod 506 by bolts. The vertical position of the installation rod 507 relative to the connecting rod 506 can be adjusted. A buffer head 508 is elastically mounted on the bottom of the installation rod 507. A pressure wheel 509 is rotatably mounted on the buffer head 508. Specifically, a connecting pin 510 is symmetrically fixed on the top of the buffer head 508. The top of the connecting pin 510 is connected to the installation rod 507 by a spring 511 for buffer sliding.

[0022] The position adjustment assembly 6 includes a vertical mounting plate 601 fixed on the base plate 2. The top of the vertical mounting plate 601 is fixed to a telescopic cylinder 602. The output end of the telescopic cylinder 602 is fixedly connected to a slider 603 that can slide up and down along the vertical mounting plate 601. A threaded adjustment unit 604 is fixed on the slider 603. A tool holder 605 is fixed on the output end of the threaded adjustment unit 604.

The sliding distance can be read by a scale 608. It should be noted that the thread adjustment component 604 has the same structure as the micrometer, which is a mature existing technology and will not be described in detail here. Alternatively, a micrometer can be used directly as a replacement, in which case the thread adjustment component 604 and the slider 603 need to be able to slide relative to each other before the bolt is tightened. To accommodate rubber rings of different sizes, the positioning mold 4 can be changed accordingly, and the installation positions of the position adjustment component 6 and the clamping component 5 can also be adjusted. The base plate 2 has pre-drilled fastening thread holes corresponding to different specifications.

[0023] In use, the rubber ring is placed in the bearing groove 401 on the positioning mold 4. Then, the rotary cylinder 502 is started, driving the lifting shaft 503 to rotate. During the rotation, the lifting shaft 503 moves downward, and the buffer head 508 moves accordingly until it is pressed against the corresponding position on the top of the rubber ring. After being pressed, the telescopic cylinder 602 is started to descend, so that the two blades reach the inner and outer cutting positions of the rubber ring respectively. Then, the motor is started to drive the rotating disk 3 to rotate, and the positioning mold 4 rotates accordingly. After one rotation, the inner and outer sides of the rubber ring move one revolution relative to the corresponding blades, thereby cutting off the flash. The rotary cylinder 502 and the telescopic cylinder 602 are driven to drive the output end back to the initial position. The cut flash and the finished rubber ring are then taken out, thus completing one flash cutting process.
