Description

Technical Field

[0001] The utility model relates to the technical field of trimming of sealing rings, and more specifically, to a trimming machine for sealing rings. Background Art

[0002] A rubber ring is a common sealing element. When a rubber ring is produced, it first needs to be pressed in a mold. When a rubber molded product is vulcanized, the rubber compound quickly fills the mold cavity, and the excess part (in order to prevent lack of rubber, the rubber compound filled in the mold cavity is appropriately maintained with a certain amount of interference) overflows, forming overflow rubber, that is, flash. In order to make the product meet the specified dimensions and ensure the appearance quality, the excess rubber edges need to be removed from the vulcanized finished product first, and this process is commonly called trimming. However, it is found in the use of existing sealing ring trimming machines that they can only cut sealing rings of a single model, with relatively high limitations in use. There are a wide variety of sealing rings with large size requirements, and if all are equipped with corresponding devices, the cost is too high. Content of the Utility Model

The sliding groove one and the sliding groove two opened on the support frame 4. The sliding groove one can control and limit the fixing frame one 5 to move left and right in the sliding groove one, so as to achieve the effect of controlling the left and right positions of the trimming bit 7. The moving groove two can control and limit the fixing frame one 5 to move back and forth in the sliding groove two, so as to achieve the effect of controlling the front and back positions of the trimming bit 7, and then achieve the effect that the device can trim trimming machines of various sizes.

[0022] Among them, a square fixing block is fixedly sleeved on the output end of the motor 8. The fixing block is located at the upper end of the chassis 1. A fixing hole one with a shape and size that fits the fixing block is opened in the center of the fixed base 3. A fixing hole two for fixing the sealing ring is opened inside the fixed base 3.

[0023] The square fixing block can better control its position and will not slip when the fixing base 3 rotates, enabling the fixing base 3 to be fixed better.

[0024] Among them, a sliding groove one and a sliding groove two are opened inside the upper end of the support frame 4. The sliding groove one in a set of front and back positions is higher than the sliding groove two in a set of left and right positions. The fixing frame one 5 is located in the sliding groove one, and the fixing frame two 6 is located in the sliding groove two.

[0025] The sliding groove one can control and limit the fixing frame one 5 to move left and right in the sliding groove one, thereby achieving the effect of controlling the left and right positions of the trimming drill bit 7. The moving groove two can control and limit the fixing frame one 5 to move back and forth in the sliding groove two, thereby achieving the effect of controlling the front and back positions of the trimming drill bit 7.

[0026] Among them, a moving groove one is opened at the center position of the lower end of the fixing frame one 5, a fixing groove one is opened at the upper right position of the fixing frame one 5, a moving groove two is opened at the center position of the upper end of the fixing frame two 6, and a fixing groove two is opened at the lower front position of the fixing frame two 6.

[0028] Among them, there are four nuts 10, which are respectively located at the tops of the fixing frame one 5 and the fixing frame two 6. The nuts 10 are engaged at both ends of the fixing frame one 5 and the fixing frame two 6 on the surface of the support frame 4.

[0029] By tightening or loosening the nuts 10, the positions of the fixing frame one 5 and the fixing frame two 6 inside the sliding groove can be controlled.

[0030] Among them, the upper end and the lower end of the connecting component 9 are respectively located in the moving groove one and the moving groove two. There are two fixing components 11, which are respectively located at the left end and the rear end of the trimming drill bit 7 and the fixing components 11 are respectively located in the moving groove one and the moving groove two.

[0031] The upper end and the lower end of the connecting component 9 are respectively located in the moving groove one and the moving groove two. The connecting component 9 is used to connect the fixing frame one 5 and the fixing frame one 5. There are two fixing components 11, which are respectively located at the left end and the rear end of the trimming drill bit 7 and the fixing components 11 are respectively located in the moving groove one and the moving groove two, so as to achieve the purpose of restricting and controlling the position of the trimming drill bit 7.

[0032] The working principle and usage process of the present utility model:

[0033] When trimming the sealing ring, first select fixed bases 3 of different sizes according to requirements, and then place the fixed base 3 on the fixed block at the output end of the motor 8. Adjust the position of the cleaning component 12 in the moving groove 13 by tightening and loosening the bolt 14, so that the cleaning component 12 is located above the position of the fixed base 3. Then loosen the nuts 10 at both ends of the first fixing frame 5 and the second fixing frame 6, so that the first fixing frame 5 and the second fixing frame 6 can move in the first sliding groove and the second sliding groove. According to the different sizes of the installed fixed base 3, adjust the positions of the first fixing frame 5 and the second fixing frame 6. While adjusting the positions of the first fixing frame 5 and the second fixing frame 6, the trimming drill bit 7 also moves accordingly. The fixing component 11 moves together in the first fixing groove and the second fixing groove of the first fixing frame 5 and the second fixing frame 6. After adjusting the position, tighten the nuts 10 at both ends of the first fixing frame 5 and the second fixing frame 6 to complete the fixation. Since the first fixing frame 5 and the second fixing frame 6 are both fixed, the trimming drill bit 7 cannot move on the horizontal plane. At this time, the sealing ring to be trimmed can be placed into the fixed base 3 to complete the trimming operation. When the trimming drill bit 7 finishes trimming the sealing ring, the trimmed scraps will be swept out of the working area because the fixed base 3 rotates and contacts the cleaning component 12, ensuring that scattered debris and small rubber particles will not accumulate in the trimming working area and cause interference.
