[0002] During the cutting process of a vertical internal circle cutting machine, the workpiece obtained by cutting (such as a glass lens, etc.) is currently mostly removed manually from under the blade. However, the above manual removal method may collide with the rotating blade and cause personal injury to personnel, so there is a great risk of safety hazards.

[0003] Therefore, in the prior art with application number 202121477289.8 and patent name “Protective cover for internal circle cutting machine”, a protective cover is set to cover the cutting machine head and cutting blade to prevent the cutter head and the cut workpiece from being exposed to the working environment, thus preventing workers from being cut by the blade or the workpiece. However, in this solution, the baffle of the protective cover is only installed on the non-processing side of the blade, and the cutting edge on the processing side is not protected. When removing the workpiece, the personnel are still at risk of injury. At the same time, the protective cover is fixedly installed and its position cannot be moved and adjusted, so it will limit the space for movement each time the blade is retracted, hindering the cutting process.

[0033] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0034] Example 1

[0035] like Figure 1 As shown, this embodiment provides a protective tooling for an internal circle cutting machine, which includes the following components:

[0036] Linear drive components;

[0037] A mounting seat 1, which is connected to the linear drive assembly;

[0038] A lifting drive assembly connected to the mounting seat 1;

[0039] and a baffle 2 connected to the lifting drive assembly;

[0040] The linear drive assembly is used to drive the lifting drive assembly and the baffle 2 to move linearly in the horizontal direction, and the lifting drive assembly is used to drive the baffle 2 to move linearly in the height direction to complete the adjustment of the horizontal position and / or height position of the baffle 2, so that the baffle 2 reaches a predetermined position to cover the blade of the inner circle cutting machine.

[0041] Specifically, the linear drive assembly includes:

[0042] The guide rail 7 is arranged on the side of the inner circle cutting machine 100. For example, in this embodiment, there are two groups of guide rails 7, which are respectively located on both sides of the inner circle cutting machine 100 and are arranged parallel to each other;

[0043] A slider 9, which is slidably matched with the guide rail 7 and connected to the mounting seat 1; correspondingly, there are two groups of sliders 9, and each of them is slidably matched with one group of guide rails 7;

[0044] A linear drive unit is used to drive the slider 9 to move linearly along the guide rail 7; for example, in this embodiment, the linear drive unit includes a push rod 8, which is connected to the slider 9 and / or the mounting base 1, and a person can drive the slider 9 to move linearly along the guide rail 7 by holding the push rod 8 and manually pushing it. Correspondingly, there can also be multiple groups of push rods 8, or the linear drive unit includes mechanical components such as gears, racks, screws, cylinders / motors, etc., and the slider 9 is further driven to move linearly along the guide rail 7 through cylinder linear drive, motor driven gears, rack meshing transmission / screw transmission, etc.

[0045] Furthermore, the mounting base 1 includes a U-shaped main body 101, a first connecting part 102 and a second connecting part 103, wherein the first connecting part 102 and the second connecting part 103 are respectively connected to the two ends of the U-shaped main body 101, and the extension directions of the first connecting part 102 and the second connecting part 103 are opposite. At the same time, the first connecting part 102 and the second connecting part 103 are respectively connected to a detachable slider 9. For example, the first connecting part 102 and the second connecting part 103 can be detachably connected to the slider 9 through connecting holes 11, bolts and other components.

[0046] The lifting drive assembly comprises:

[0047] A lifting drive unit 6, which is mounted on the mounting base 1;

[0048] and a baffle connecting member 4, which is respectively connected to the power output end of the lifting drive unit 6 and the baffle 2 through screws 5 and other components;

[0049] The lifting drive unit 6 drives the baffle connecting member 4 and the baffle 2 to move linearly in the height direction through its power output end;

[0050] For example, in this embodiment, the lifting drive unit 6 includes mechanical components such as a cylinder / motor, a screw, a gear, and a rack, and can drive the baffle connector 4 and the baffle 2 to move linearly in the height direction through cylinder drive, motor drive gear, rack meshing transmission / screw drive, etc.

[0051] In addition, in this embodiment, the baffle 2 can be a U-shaped structure as a whole, and can be made of materials such as plastic, metal (such as aluminum alloy, stainless steel, etc.).

[0052] Embodiment 2:

[0053] The only difference between this embodiment and embodiment 1 is that the linear drive assembly further includes: a limit block 3, which is connected to the guide rail 7 and is used to limit the moving distance of the slider 9. For example, in this embodiment, a group of guide rails 7 may be provided with a plurality of (such as 2-3) limit blocks 3, and at the same time, the slider 9 is located between two adjacent limit blocks 3, thereby limiting the moving distance of the slider 9.

[0054] Embodiment 3:

[0055] The only difference between this embodiment and Embodiment 1 or 2 is that the lifting drive unit 6 includes: a cylinder, an air pressure control valve and a reversing valve, wherein the cylinder drives the baffle connector 4 and the baffle 2 to move linearly in the height direction through the telescopic movement of its power output end; the air pressure control valve (including a pressure reducing valve, a solenoid valve, etc.) is used to control the cylinder air pressure, and then control the telescopic movement speed of the power output end of the cylinder, thereby adjusting the lifting speed of the baffle 2; the reversing valve is used to change the flow direction of the gas in the cylinder so that the power output end of the cylinder extends / retracts.

[0056] The working process of the above protective tooling is as follows:

[0057] like Figure 2a As shown, when the workpiece P needs to be taken out, the linear drive unit drives the slider 9, the lifting drive assembly, and the baffle 2 to move linearly along the guide rail 7 synchronously by pushing the push rod 8 or the like, until they reach above the inner circle cutting machine blade B, and then the lifting drive unit 6 drives the baffle 2 to descend by operating the reversing valve or the like, until the blade B is blocked, at which time the personnel can reach out to pull out the shock-absorbing pad 12 under the blade B and take out the workpiece P on the shock-absorbing pad 12;

[0058] like Figure 2b As shown, the shock-absorbing pad 12 is pushed back under the blade B, and then the reversing valve and other mechanisms are operated to make the lifting drive unit 6 drive the baffle 2 to rise, and then by pushing the push rod 8 and other methods, the linear drive unit drives the slider 9, the lifting drive assembly, and the baffle 2 to move synchronously along the guide rail 7 in a straight line until they reach a position away from the blade B, so that there is no obstacle above the blade B, so that the internal circle cutting machine completes the retracting action and continues cutting to obtain the next workpiece.

[0059] Embodiment 4:

[0060] The difference between this embodiment and embodiment 1 or 2 is that Figure 1As shown, the mounting base 1 is provided with a hollow structure 104. For example, the hollow structure 104 can be provided on the U-shaped main body 101 and / or the first connecting portion 102 and / or the second connecting portion 103 to reduce the overall weight of the structure. Figure 2a As shown, a notch 201 is provided on the baffle plate 2 to prevent the baffle plate 2 from interfering with other structures, such as the pipeline 10 below the baffle plate 2, when the baffle plate 2 is lowered.

[0061] In summary, the protective tooling in the utility model has a good protective effect, so that when personnel take out items, there is no exposed blade in front and behind the blade, which can greatly reduce the safety risk when personnel manually take out items. At the same time, the baffle can move forward and backward, up and down, and does not affect the advance and retreat of the blade. In addition, the above-mentioned protective tooling has a low manufacturing cost and does not require major changes to the existing internal circle cutting machine equipment. At the same time, a limit block is set on the guide rail, which can prevent the collision between the baffle and the blade even if an erroneous operation occurs.

[0062] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
