Description

Technical Field

[0001] The invention relates to the technical field of chuck tooling, in particular to a chuck tooling used for machining three-way valves. Background Art

[0002] The three-way valve is a control component in the fluid conveying system, which has the functions of shutoff, regulation, diversion, prevention of backflow, pressure stabilization, diversion or overflow. The three-way valve usually needs to be fixed by a chuck during the processing, and the chuck is a specially designed clamping device used to firmly fix the workpiece on the machine tool for various processing operations, such as turning, milling, drilling, etc. Its main functions include clamping, positioning and support, among which clamping is to firmly fix the workpiece to prevent the three-way valve from moving or vibrating during the processing, so as to better process the three-way valve.

[0003] The existing chuck tooling still has the following defects during use:

[0004] 1. When the chuck tool is clamping the three-way valve, the outer surface of the three-way valve is too smooth and the shape of the three-way valve is irregular, which makes the three-way valve easy to loosen during the processing after being clamped by the chuck tool, causing the three-way valve to shake during the processing, affecting the normal processing of the three-way valve, thereby reducing the processing accuracy of the three-way valve.

[0005] 2. The three-way valve generates a large amount of debris during the processing, and coolant or cutting fluid is sprayed during the processing to improve the processing effect. Some of these debris float in the air. Due to the irregular shape of the three-way valve, there is a certain gap between the three-way valve and the chuck tooling, causing the debris to rely on air flow or liquid splashing to be adsorbed on the outer surface of the three-way valve and the inside of the chuck tooling from the gap between the outer surface of the three-way valve and the chuck tooling. Therefore, the three-way valve and the chuck tooling need to be cleaned for subsequent processing. However, during the cleaning process, the three-way valve and the chuck tooling need to be cleaned separately to achieve the purpose of removing liquid and debris, but this process is relatively complicated and has many steps, which prolongs the cleaning time of the three-way valve and the chuck tooling.

[0046] Compared with the prior art, the present invention adopts the processing hole and the protruding column 48 to further strengthen the clamping force between the clamp block 3 and the three-way valve to prevent the occurrence of low clamping force due to the smooth surface of the three-way valve, and utilizes the processing hole to allow debris to enter the processing hole from the gap between the three-way valve and the clamp block 3 during processing to prevent the debris from contacting the three-way valve and damaging the surface of the three-way valve, and the anti-slip pad 49 can further reduce the wear between the protruding column 48 and the surface of the three-way valve, thereby preventing scratches on the surface of the three-way valve, and at the same time, a double fixing method is used to fix the introduction tube 51 on the top of the clamp block 3, so as to facilitate the cleaning of the processed three-way valve and the clamp block 3, which is beneficial to further expand the use range of the processing hole, thereby improving the practicality of the processing hole, and the installation method of the introduction tube 51 is simply designed, which effectively improves the overall processing efficiency of the three-way valve, and reduces the difficulty of installing the introduction tube 51, thereby facilitating user operation.

[0047] Working principle:

[0048] Initial limit:

[0049] Before using the present invention, the user needs to connect the end of the inlet pipe 51 away from the clamping block 3 to an external water source. At this time, the water source is in a closed state, and the states of the other parts are the same as Figures 1 to 12 As shown;

[0050] Multiple processing steps:

[0051] First, the user needs to place the three-way valve in the Figure 1 Inside the clamping block 3 shown below, each pipeline of the three-way valve is in contact with the inner wall of the clamping groove 1 and the two clamping grooves 2 respectively, and the power supply of the chuck body 1 is turned on, so that the chuck body 1 starts to work, and the chuck body 1 drives the two claws 2 to approach each other with the chuck body 1 as the center. In the process of approaching each other with the chuck body 1 as the center, the claws 2 synchronously drive the clamping block 3 to approach each other with the chuck body 1 as the center, so that the two clamping blocks 3 move in opposite directions, so that the three-way valve is clamped by the two clamping blocks 3, and the processing holes can be used to strengthen the friction between the clamping block 3 and the three-way valve during the process of the clamping block 3 clamping the three-way valve, so as to prevent the occurrence of low clamping force due to the smooth surface of the three-way valve, and further improve the stability of the three-way valve during the processing;

[0052] The user observes with the naked eye that the two clamping blocks 3 clamp the three-way valve during the opposite movement. The principle of their opposite movement is consistent with the above. The user needs to turn off the power of the chuck body 1. Figure 3 and Figure 5 As shown, the user manually rotates the positioning block 43 counterclockwise, and the positioning block 43 synchronously drives the integrated positioning sleeve at the bottom end of the positioning block 43 to rotate counterclockwise during the counterclockwise rotation. Since the positioning block 43 is threadedly connected to the outer surface of the rotating shaft 42, and the integrated positioning sleeve at the bottom end of the positioning block 43 is threadedly connected to the top of the clamping block 3, the positioning block 43 gradually moves upwards by relying on the thread during the counterclockwise rotation. Then, the integrated positioning sleeve at the bottom end of the positioning block 43 gradually disengages from the top end of the clamping block 3 by relying on the thread during the counterclockwise rotation. As a result, when the integrated positioning sleeve at the bottom end of the positioning block 43 is completely disengaged from the top end of the clamping block 3, the fixed state of the rotating shaft 42 is released, so that the rotating shaft 42 is no longer fixed to the top end of the clamping block 3 by the integrated positioning sleeve at the bottom end of the positioning block 43 and the positioning block 43. At this time, the user needs to manually rotate the rotating block 41 clockwise. The rotating block 41 synchronously drives the rotating shaft 42 to rotate clockwise during the clockwise rotation. Figure 5 , Figure 6 and Figure 8 As shown, the rotating shaft 42 synchronously drives the screw 44 to rotate clockwise during the clockwise rotation process. Since the transmission block 45 is threadedly connected to the screw 44 and the transmission block 45 is slidably connected to the inner wall of the processing chamber, the transmission block 45 is synchronously driven to move downward during the clockwise rotation of the screw 44. The transmission block 45 synchronously drives the connecting rod 46 to move downward during the downward movement. The connecting rod 46 synchronously drives the connecting rod 46 downward during the downward movement. The connecting rod 46 synchronously drives the top plate 47 downward during the downward movement. The top plate 47 synchronously drives the boss 48 at the bottom end of the top plate 47 to move downward during the downward movement, as shown in FIG. Figure 6 and Figure 7 As shown, the transmission block 45 can also synchronously drive the transmission frame 410 to move downward during the downward movement, and the transmission frame 410 synchronously drives the top plate 411 to move downward during the downward movement, and the top plate 411 synchronously drives the protruding column 48 at the bottom end of the top plate 411 to move downward during the downward movement, and at the same time, the top plate 47 synchronously drives the connecting frame 412 to move downward during the downward movement, and the connecting frame 412 synchronously drives the top plate 411 away from the screw rod 44 to move downward during the downward movement, thereby driving the protruding column 48 at the bottom end of the top plate 411 to move downward, so as to use the protruding column 48 to move downward. The convex column 48 moves downward through the processing hole, and then supports the three-way valve, thereby preventing the three-way valve from reducing the contact area with the clamping block 3 due to the processing hole during the clamping process, and can further increase the friction between the three-way valve and the clamping block 3. The convex column 48 simultaneously drives the anti-skid pad 49 to move downward during the downward movement, which can further reduce the wear between the convex column 48 and the surface of the three-way valve, and the soft anti-skid pad 49 can better adapt to the irregular surface of the three-way valve, increase the contact area with the valve of complex shape, and prevent scratches on the surface of the three-way valve, which is beneficial to protect the appearance of the three-way valve.

[0053] Then the user needs to reverse the steps of the positioning block 43 and the integrated positioning sleeve at the bottom of the positioning block 43, so that the positioning block 43 and the integrated positioning sleeve at the bottom of the positioning block 43 are restored to Figure 3 and Figure 5 The state shown in the figure prevents the screw rod 44 from rotating under the action of external force;

[0054] Double fixing steps:

[0055] After the three-way valve is processed, the user connects the water source, and the water in the water source enters the inside of the introduction pipe 51, and the water enters the inside of the introduction port from the inside of the introduction pipe 51, and the water enters the inside of the treatment chamber from the inside of the introduction port, and then sprays out from the treatment hole, so as to flush the surface of the three-way valve and the inner walls of the clamping groove 1 and the clamping groove 2, and complete the cleaning of the surface of the three-way valve and the clamping block 3, saving the time of cleaning the three-way valve after transportation;

[0056] When the user needs to install the rotating mechanism on the side of the chuck body 1 away from the claw 2, the user needs to install the rotating mechanism on the side of the chuck body 1 away from the claw 2 before processing the three-way valve. Fig.10 As shown, the user manually moves the control block 53 upwards, and the control block 53 drives the control rod 54 upwards during the upward movement. The control rod 54 drives the limit plate 56 upwards during the upward movement. The limit plate 56 drives the spring 57 to be compressed during the upward movement, causing the spring 57 to deform. When the user feels that the control block 53 cannot be pulled upwards any further, as shown in FIG. Figure 4As shown, at this time, the user needs to manually pull the control block 53 in the direction away from the mounting block 52, so that the control block 53 is away from the mounting block 52. Since the control block 53 is slidably connected to the control rod 54, the control block 53 synchronously drives the control rod 54 away from the mounting block 52 during the process of moving away from the mounting block 52. The control rod 54 synchronously drives the control seat 55 away from the mounting block 52 during the process of moving away from the mounting block 52. The control seat 55 synchronously drives the insert block 58 to be separated from the slot in the mounting block 52 during the process of moving away from the mounting block 52. Fig.11 and Fig.12 As shown, the insert block 58 simultaneously drives the arc-shaped clamping block 510 to disengage from the clamping slot during the process of disengaging from the internal slot of the mounting block 52. Therefore, the inner wall of the arc-shaped clamping block 510 is pressed by the inner wall of the slot when disengaging from the clamping slot, causing the arc-shaped clamping block 510 to be pressed into the interior of the insert block 58. In the process of being pressed, the arc-shaped clamping block 510 simultaneously presses the elastic strip 59, causing the elastic strip 59 to deform. When the insert block 58 is completely out of the slot, the arc-shaped clamping block 510 is no longer pressed by the inner wall of the slot, causing the arc-shaped clamping block 510 to pop out by the rebound force of the elastic strip 59, thereby removing the introduction tube 51 from the top of the clamp block 3. This method is simple to operate. By simply designing the installation method of the introduction tube 51, the overall processing efficiency of the three-way valve is effectively improved, and the difficulty of installing the introduction tube 51 is reduced, thereby facilitating the user's operation.

[0057] like Figure 4 As shown, when the user observes with naked eyes the control slot on the side of the control seat 55 away from the mounting block 52 that is not blocked by the control seat 55, as shown in FIG. Fig.10 As shown, at this time, the user needs to release the control block 53, so that the control rod 54 moves downward by the resilience of the spring 57, so that the bottom end of the control rod 54 contacts the top end of the clamping block 3, so that the top end of the clamping block 3 supports the control rod 54, and the spring 57 is still in a deformed state, and then moves away from the mounting block 52 again, so that after continuing to move away from the mounting block 52, as shown in FIG. Figure 4 As shown, when the control rod 54 moves to a point where the control grooves away from the control block 53 are opposite to each other, the control rod 54 is no longer supported by the top of the clamp block 3. At this time, the control rod 54 can continue to move downward by the rebound force of the spring 57, causing the control rod 54 to be inserted into the control groove at the top of the clamp block 3, thereby positioning the control rod 54 at the top of the clamp block 3.

[0058] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, a person skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. Such modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
