Description

Technical Field

[0001] This utility model relates to the technical field of clamping equipment for irregular alloy parts, and more specifically to a flexible clamping and grinding platform for precision alloy irregular parts. Background Technology

[0002] When grinding alloy parts with special shapes, traditional clamping components use clamping heads that are adapted to their shape. However, these clamping heads require special mold processing, which also increases production line processing costs. On the other hand, there is a clamping base on the market that consists of multiple rods. Several rods are squeezed by the side wall of the irregular part and move horizontally, so that the clamping base forms a contact surface that matches the side wall of the irregular part due to the point distribution of clamping.

[0003] According to the publication (announcement) number: CN213614982U, the publication (announcement) date: 2021-07-06, a flexible clamp for clamping irregularly shaped aluminum alloy parts is disclosed.

[0004] In the prior art, including the aforementioned patent, in order to make the clamping surface more adaptable to the shape of the irregular part and improve the processing accuracy of the irregular part, more abutment rods are usually set for the clamping base to make the clamping more stable. However, as a result, the gaps between the rods will be smaller. When the irregular part is in the grinding state, the waste dust generated during the grinding process can easily enter the gaps. Furthermore, because the lubricating fluid required for grinding splashes into the gaps, the surface tension of the liquid adsorbs the waste dust, causing the dust to remain in the gaps. Over time, this will cause movement interference to the abutment rods, making the rods more resistant, cleaning more difficult, and the sidewalls of the rods will wear more severely. This will reduce the clamping ability of the obstructed rods on the irregular part. At the same time, the waste dust will also enter the base through the gaps, affecting the safety and normal operation of the entire clamping component. Utility Model Content

[0005] The purpose of this invention is to provide a flexible clamping and grinding platform for precision alloy irregular-shaped parts, aiming to solve the problems mentioned above.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A flexible clamping and grinding platform for precision alloy irregular parts includes a base with a clamping seat and a clamping head fixedly installed on the clamping seat, wherein the end face of the clamping head has an outer opening;

[0008] Multiple rods move horizontally within the outer opening. Each rod has a rod head for clamping irregularly shaped parts, and an outer rod that cooperates with the outer opening and leaves a gap for waste chips and powder to pass through.

[0009] The clamping head has an air chamber, and the side wall of the air chamber has an exhaust port that communicates with the outside.

[0010] Preferably, the clamping head is also provided with an air inlet that communicates with the air chamber.

[0011] Preferably, the rod is further provided with an inner rod, and the air chamber is provided with an insertion hole for the inner rod to be inserted and slidably.

[0012] Preferably, the air chamber is further provided with an air passage that connects to multiple insertion holes.

[0013] Preferably, the clamping head is further provided with a vent hole that communicates with the exhaust port, and the rod is provided with an inner retaining ring that slides in the vent hole;

[0014] By default, the inner retaining ring blocks the vent hole from supplying air to the exhaust port.

[0015] Preferably, a spring arranged in a ring on the outside of the inner rod is fixedly installed between the inner retaining ring and the air chamber.

[0016] Preferably, the rod is further provided with an outer retaining ring that slides in the vent hole, and a middle rod communicating with the exhaust port is provided between the outer retaining ring and the inner retaining ring.

[0017] Preferably, the outer retaining ring mates with the outer opening.

[0018] Preferably, the outer retaining ring has circumferentially arranged air grooves, which are connected to the exhaust port for air supply when the ring is moved.

[0019] Preferably, a rubber ring is fixedly sleeved on the outer retaining ring.

[0020] In the above technical solution, the precision alloy irregular part flexible clamping and grinding platform provided by this utility model has the following beneficial effects: by using the outer rod to increase the gap between adjacent rods, the possibility of powder mixed liquid staying in the gap is reduced. At the same time, the high-pressure gas delivered from the air chamber to the exhaust port allows the airflow to enter the outer port and diffuse, and blow onto multiple outer rods, thereby further blowing the powder liquid mixture that is not easy to stay in, greatly reducing the situation of residual waste powder in the gap, ensuring the internal stability of the clamping head, and thus keeping the clamping capacity in the best state.

[0028] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0029] like Figure 1-4 As shown, a flexible clamping and grinding platform for precision alloy irregular parts includes a base 1 with a clamping seat 11, and a clamping head 2 fixedly installed on the clamping seat 11. An outer opening 22 is provided on the end face of the clamping head 2.

[0030] Multiple rods 3 move horizontally within the outer opening 22. Each rod 3 is equipped with a rod head 31 for clamping irregularly shaped parts, and an outer rod 32 that cooperates with the outer opening 22 and leaves a gap for waste chips and powder to pass through.

[0031] An air chamber 21 is provided in the clamping head 2, and an exhaust port 26 connected to the outer opening 22 is provided on the side wall of the air chamber 21.

[0032] Specifically, the clamping seat 11 slides on the base 1, and the clamping seat 11 has an air supply component, both of which are existing technologies and will not be described in detail here.

[0033] Furthermore, the outer rod 32 is formed by a recess on the rod 3, and both ends of the recess have bevels, so as to reduce the retention capacity of the powder-liquid mixture in the gap formed by the outer rod 32.

[0034] Furthermore, the rod head 31 is located at the end of the rod 3, and the end face is rounded to improve its adaptability to the side wall of irregular parts.

[0035] Furthermore, the exhaust port 26 has an inverted "V" shaped cross section, which is used to block the powder from climbing onto the outer opening 22, increasing the difficulty for powder to penetrate into the exhaust port 26 and ensuring the stability of the gas chamber 21.

[0036] By placing the irregularly shaped part between the two clamping heads 2, the rod 3 is driven to move horizontally, and the outer rod 32 is used to increase the gap between adjacent rods 3, thereby reducing the possibility of powder and liquid mixture remaining in the gap. At the same time, the high-pressure gas delivered from the air chamber 21 to the exhaust port 26 causes the airflow to enter the outer port 22 and diffuse, and blow onto multiple outer rods 32, thereby further blowing the powder and liquid mixture that is not easy to stay, greatly reducing the situation of residual waste powder in the gap, ensuring the internal stability of the clamping head 2, and thus keeping the clamping capacity at its best.

[0037] As a further embodiment of this utility model, the clamping head 2 is also provided with an air inlet 20 communicating with the air chamber 21.

[0038] Specifically, the air inlet 20 is connected to the air supply component on the clamping seat 11.

[0039] The air inlet 20 ensures a continuous supply of high-pressure gas into the air chamber 21, making the airflow easier to use for blowing operations.

[0040] As another embodiment further provided by this utility model, the rod 3 is also provided with an inner rod 37, and the air chamber 21 is also provided with an insertion hole 23 for the inner rod 37 to be inserted and slid.

[0041] Specifically, the inner rod 37, which is arranged opposite to the rod head 31, is also formed by a recess on the side wall of the rod 3, and the inner rod 37 has the smallest diameter, which is used to reduce the impact on the airflow in the air chamber 21.

[0042] The inner rod 37 is slidably connected to the socket 23 to ensure the horizontal movement capability of the rod 3.

[0043] As another embodiment further provided by this utility model, the air chamber 21 is also provided with an air passage 24 communicating with a plurality of insertion holes 23.

[0044] Specifically, the airway 24 port is connected to the air chamber 21.

[0045] The air compressed by the inner rod 37 through the socket 23 is discharged from the vertically arranged air passage 24, thus preventing the inner rod 37 from becoming immobile.

[0046] As another embodiment of this utility model, the clamping head 2 is also provided with a vent hole 25 that communicates with the exhaust port 26, and the rod 3 is provided with an inner retaining ring 36 that slides in the vent hole 25.

[0047] By default, the inner retaining ring 36 blocks the vent hole 25 and supplies air to the exhaust port 26.

[0048] Specifically, the inner retaining ring 36 is a position on the side wall of the rod 3 where no recess is made, and the two ends of the inner retaining ring 36 are perpendicular to the horizontal plane.

[0049] The inner retaining ring 36 provides a seal for the vent 25, preventing dust and powder from entering the inside of the clamping head 2 when it is not in operation. When the rod head 31 is compressed, the inner retaining ring 36 enters the air chamber 21, causing the air chamber 21 to deliver compressed air to the exhaust port 26 through the vent 25.

[0050] As another embodiment of this utility model, a spring 38 arranged in a ring on the outside of the inner rod 37 is fixedly installed between the inner retaining ring 36 and the air chamber 21.

[0051] Spring 38 is used to ensure the horizontal movement of rod 3, while rod 3 can also be stably reset.

[0052] As another embodiment of this utility model, the rod 3 is also provided with an outer retaining ring 33 that slides in the vent hole 25, and a middle rod 35 communicating with the exhaust port 26 is provided between the outer retaining ring 33 and the inner retaining ring 36.

[0053] Specifically, the outer retaining ring 33 has no recessed position on the side wall of the rod 3, and the middle rod 35 between the outer retaining ring 33 and the inner retaining ring 36 has a bevel at one end and a vertical surface at the other end, so that the airflow entering the vent 25 can be quickly transported and flowed through the bevel of the middle rod 35.

[0054] The outer baffle ring 33 and the inner baffle ring 36 successively achieve the effects of blocking and isolating, and the middle rod 35 provides retention of a very small amount of powder, thereby keeping the environment in the air chamber 21 stable, making the airflow smoother, and improving the safety of equipment operation.

[0055] As another embodiment provided in this utility model, the outer retaining ring 33 cooperates with the outer opening 22.

[0056] The outer baffle ring 33 blocks the powder from seeping into the vent hole 25 from the outer opening 22, and the inclined surface of the outer baffle ring 33 can also guide the powder, reducing the accumulation of powder at the vent hole 25.

[0057] As another embodiment of this utility model, the outer retaining ring 33 is provided with a circumferentially arranged air groove 34, which is moved to connect with the exhaust port 26 for air supply.

[0058] The airflow delivered through the air groove 34 is diverted and discharged along multiple air grooves 34, so that the airflow acts horizontally around the outer rod 32. Combined with the airflow delivered obliquely downward through the exhaust port 26, the cleaning effect of powder mixed with liquid in the gaps is better.

[0059] As another embodiment of this utility model, a rubber ring is fixedly sleeved on the outer retaining ring 33.

[0060] Specifically, the outer retaining ring 33 has an annular groove that connects to the air groove 34. The purpose is to install the rubber ring in the annular groove, and to maintain a predetermined distance between the inner wall of the rubber ring and the inner wall of the air groove 34 after installation, so as to ensure that the air groove 34 can properly divert gas.

[0061] Furthermore, two annular grooves are provided on the inner retaining ring 36 for installing rubber rings.

[0062] By using a rubber ring to improve the blocking and sealing effect on the vent 25, the airflow is not interfered with, making the inside of the clamping head 2 more stable.

[0063] Working principle: By placing the irregular part between the two clamping heads 2, the rod 3 is driven to move horizontally. The outer rod 32 is used to increase the gap between adjacent rods 3, so as to reduce the possibility of powder and liquid mixture staying in the gap. At the same time, the high-pressure gas delivered from the air chamber 21 to the exhaust port 26 causes the airflow to enter the outer port 22 and diffuse, and blow onto multiple outer rods 32, thereby further blowing the powder and liquid mixture that is not easy to stay, greatly reducing the situation of residual waste powder in the gap.

[0064] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
