DETAILED DESCRIPTION

[0034] In order to further illustrate the method adopted by the present invention and the effect achieved, the technical solution of the present invention will be clearly and completely described in combination with experiments below.

[0035] Example 1: Figures 1 to 3 As shown, a titanium alloy grinding processing device for preventing waste from splashing includes a box body 1 with an opening on one side, a barrier door assembly 2 arranged in the opening, and a titanium alloy placement component 3 arranged inside the box body 1;

[0036] The barrier door assembly 2 includes a screw 21 rotatably connected to the inner wall of the box body 1 at one end, a gear 22 rotatably arranged on the inner wall of the box body 1 and fixedly connected to the other end of the screw 21, a first rack 23 and a second rack 24 respectively meshing with the top and the bottom of the gear 22, two barrier doors 25 slidably arranged in the opening and respectively corresponding to the first rack 23 and the second rack 24 fixedly connected, and a first motor arranged on the inner wall of the box body 1 for driving the screw 21 to rotate;

[0037] The screw rod 21 is hollow inside and is inserted with a spline rod 211. The spline rod 211 penetrates the box body 1 and is connected to the knob 11 outside the box body 1. The gear 22 is connected to the spline rod 211.

[0038] The titanium alloy placement assembly 3 includes a connection block 31 threadedly sleeved on the screw rod 21, a placement table 32 slidably disposed inside the box body 1 and fixedly connected to the connection block 31, and a clamping assembly 33 disposed on the placement table 32 for clamping the titanium alloy;

[0039] The clamping assembly 33 includes mounting plates 331 disposed on both sides of the placement platform 32, a threaded tube 332 disposed between the two mounting plates 331 and having threads disposed on both sides in opposite directions, a clamping member 333 threadedly connected to both sides of the threaded tube 332, and a second motor disposed outside the mounting plates 331 and having an output shaft connected to the threaded tube 332;

[0040] An observation window 250 is installed on the barrier door 25, and a control panel 15 for starting and stopping the first motor and the second motor is fixedly installed on one side of the box body 1;

[0041] The working principle of this embodiment is as follows: when the staff needs to grind the titanium alloy, first the staff can control the first motor to work through the control panel 15, so that the first motor drives the screw 21 to rotate, and then the screw 21 drives the placement table 32 to move along the inside of the box body 1 through the connecting block 31, until the placement table 32 moves to a position close to the barrier door 25 and stops. In this process, the screw 21 drives the gear 22 to rotate, so that the gear 22 drives the first rack 23 and the second rack 24 to rotate, and then the first rack 23 and the second rack 24 drive the corresponding barrier doors 10 to move away from each other, open the seal of the box body 1, so as to achieve the effect of automatically opening the barrier door 25, so that the staff can place the titanium alloy workpiece to be ground on the clamping assembly 33 on the placement table 32;

[0042] Then the staff can control the second motor to work through the control panel 15, so that the second motor drives the clamping member 333 to move through the threaded tube 332, and the clamping member 333 clamps and fixes the titanium alloy workpiece, so as to achieve the effect of quickly clamping and fixing the titanium alloy workpiece, which is convenient for the staff to fix or stop fixing the titanium alloy workpiece. Then the staff can control the first motor to work in reverse through the control panel 15, so that the first motor drives the screw 21 to rotate in the opposite direction, and then the screw 21 drives the placement table 32 to reset through the connecting block 31, and the reversal of the screw 21 will drive the gear 22 to reverse, so that the gear 22 drives the first rack 23 and the second rack 24 to move and reset, and then the first rack 23 and the second rack 24 drive the corresponding barrier doors 25 to get close to each other and get stuck together, so as to seal the box body 1, so as to achieve automatic installation. The barrier door 25 is sealed and protected by the device, and the staff does not need to manually seal the barrier door 25, which prevents the staff from forgetting to seal the barrier door 25 or failing to completely seal the barrier door 25, resulting in debris and sparks flying out when the titanium alloy workpiece is ground inside the device, causing harm to the staff; when the staff does not need the barrier door 25 to open and close automatically, the staff can turn the knob 11 to make the knob 11 drive the spline rod 211 to move along the extension direction of the thread inside the box body 1, thereby making the spline rod 211 disengage from the inside of the screw rod 21. At this time, the rotation of the screw rod 21 cannot drive the gear 22 to rotate through the spline rod 211, so that the automatic opening and closing of the barrier door 25 stops, and the staff can manually pull the barrier door 25 to open and close, which is convenient for the staff to make changes according to usage requirements and improve the scope of application of the device.

[0043] Embodiment 2: Different from Embodiment 1, Figure 4 As shown, the screw rod 21 is provided with a first spline 216 and a second spline 212, the screw rod 21 is slidably sleeved with a first sleeve 213 engaged with the first spline 216, and a second sleeve 214 arranged between the first spline 216 and the second spline 212 and capable of engaging with the second spline 212, a slide groove 10 is provided on the top of the box body 1, and a slider 12 slidably connected with the slide groove 10 is provided on the top of the two barrier doors 25, an air column 13 is provided between the two sliders 12, an air bag column 215 connected with the air column 13 through a pipeline is provided between the first sleeve 213 and the second sleeve 214, and the air bag column 215 is rotatably limitedly connected with the first sleeve 213 and the second sleeve 214, the gear 22 is threadedly connected with the first sleeve 213, and the second sleeve 214 is threadedly connected with the connecting block 31; it should be noted that, Figure 4 is the positional relationship of the above components in the initial state;

[0044] The working principles of this embodiment are basically the same as those of Embodiment 2, except that the door is automatically closed: in the initial state, the first spline 216 is engaged with the first sleeve 213, and the second spline 212 is not in contact with the second sleeve 214, and the first motor is driven to rotate the screw 21, driving the first rack 23 and the second rack 24 to move, closing the barrier door 25. At the same time, the first rack 23 and the second rack 24 will squeeze the air column 12 during their movement toward each other. When the barrier doors 25 on both sides are about to contact, the barrier doors 25 are quickly closed under the action of the electromagnet 251. At this time, the airbag column 215 will expand, causing the first sleeve 213 to fall off from the first spline 216, and the second sleeve 214 to engage with the second spline 212. At this time, the screw 21 rotates while the first sleeve 213 does not rotate, that is, the barrier door 25 is maintained in a closed state and the position of the placement table 32 can continue to be adjusted by the first motor driving the screw 21, so that the grinding machine can accurately align it for processing.

[0045] Embodiment 3: Different from embodiment 2, Figures 5-6 As shown, an electromagnet 251 is provided on the contact surface of the two barrier doors 25, a spring 252 is provided between the slider 12 and the slide slot 10, and a push switch 14 is provided on the side wall of the box body 1, which can trigger the electromagnet 251 to cut off the power for 3s during the reset process of the placement table 32; wherein, the reset means that the placement table 32 moves to its initial position, that is, close to the opening side of the box body 1. In this embodiment, the push switch 14 adopts a commercially available key switch (normally open type), which cuts off the power when pressed and turns on the power when released;

[0046] The working principle of this embodiment is basically the same as that of Embodiment 2, except that when the placement table 32 moves to the outside, the outer push switch 14 is pressed to discharge, so that the barrier door 25 is opened under the action of the spring 252. At this time, the air column 12 expands to cause the airbag column 215 to contract, thereby realizing the separation of the second sleeve 214 from the second spline 212, and the fixation of the first sleeve 213 and the first spline 216, and further enabling the barrier door 25 to open slowly under the action of the gear, so that the staff can remove and take out the titanium alloy workpiece on the placement table 32 conveniently, and prevent the titanium alloy workpiece from being too far away from the opening of the box body 1, which affects the staff's removal and taking out of the titanium alloy workpiece.

[0047] Embodiment 4: Different from Embodiment 3, Figure 7 As shown, the placement table 32 is composed of a plurality of placement plates and a frame body. The placement plates include a plurality of plate bodies 321 with rotating shafts 320 at both ends. The plurality of rotating shafts respectively penetrate the frame body and are connected to the first limit block 322 on the frame body. The threaded tube 332 penetrates the mounting plate 331 and is fixedly connected to the second limit block 323. The first limit block 322 and the second limit block 323 are connected by a first transmission belt; the plurality of rotating shafts are connected by a second transmission belt.

[0048] The working principle of this embodiment is basically the same as that of Embodiment 3, except that the reciprocating rotation of the threaded tube 332 can be used to drive the plate body 321 to reciprocate, thereby removing residual waste residue on the surface of the plate body 321 and reducing the adhesion of the adhesive on the surface of the plate body 321.

[0049] Embodiment 5: Different from Embodiment 1, not shown in the figure, a ball bearing is provided on the side of the barrier door 25; specifically, the ball bearing is provided at the bottom of the side of the barrier door and contacts the inner wall of the opening, and the ball bearing is a commercially available steel ball;

[0050] The working principle of this embodiment is basically the same as that of Embodiment 1, except that during the sliding process of the barrier door 25, the sliding friction is converted into rolling friction under the action of the ball bearings, thereby reducing the friction force and improving the sliding efficiency and accuracy of the barrier door 25.
