DETAILED DESCRIPTION

[0031] like Figures 1 to 8 As shown, the present invention mainly includes a support frame 1, a clamping mechanism 4, a limiting mechanism 7 and a purification mechanism 5. The present invention is described in detail below in conjunction with the accompanying drawings.

[0032] like Figure 1 As shown, the support frame 1 is the basic component of the present invention, which is used to install other components. The support frame includes two parts fixedly connected together, the lower part is a plate-shaped base 11, and the upper part is a bracket 12, and the bracket is a "["-shaped structure with the opening facing downward. A welding machine 2 is arranged on the front surface of the support frame 1, which is used to realize the welding of the composite plastic tile and the metal steel back. The metal steel back is placed on the inner side of the support frame 1, and the metal steel back is placed on the upper surface of the base and is placed in the center. Composite plastic tiles 6 are respectively arranged on the two end surfaces of the metal steel back 3. A clamping mechanism is provided in the middle position of the base, and the clamping mechanism is placed horizontally, and the clamping mechanism is used to realize the clamping of the bearing.

[0033] like Figures 2 to 4 As shown, the clamping mechanism includes an adjustment box 41, a pad 42, a connecting plate 43, an extrusion block 44, a hydraulic push rod 46 and a movable block 47. The adjustment box 41 is fixed on the upper surface of the base. The adjustment box is a cylindrical hollow structure. A plurality of pads 42 are evenly arranged along the circumference on the outside of the adjustment box 41. The pads are arc-shaped plates. A plurality of extrusion blocks 44 are evenly arranged along the circumference on the inside of the adjustment box. The longitudinal section of the extrusion block is a right-angled trapezoid, and the side of the extrusion block facing the axis of the adjustment box is an inclined surface. There is a one-to-one correspondence between the extrusion blocks and the pads, and a connecting plate 43 is provided between the vertical side wall of the corresponding extrusion block and the inner side wall of the pad. The connecting plate is slidably arranged on the side wall of the adjustment box. A through hole 45 is provided on the top of the adjustment box, and the through hole is located on the axis of the adjustment box. A vertically placed hydraulic push rod 46 is provided inside the regulating box 41 , the axis of the hydraulic push rod 46 coincides with the axis of the regulating box, and a conical movable block 47 is fixedly connected to the upper end of the hydraulic push rod 46 , with the tip of the movable block facing upward.

[0034] In order to solve the problem that it is difficult to use a fixture to fix the position of the bearing when the bearing processing equipment in the prior art processes the bearing, and the problem that the position of the bearing is easy to move when the bearing is processed, such as Figures 1 to 5 As shown, when the present invention is in use, the bearing sleeve is arranged outside the adjustment box 41, and the staff operates the processing equipment to control the hydraulic push rod 46 to push the movable block 47 upward. During the upward movement of the movable block 47, the extrusion block 44 is pushed to move outward, and then the pad 42 is driven to expand outward through the connecting plate 43. The arc-shaped pad 42 is tightly fitted with the inner wall of the circular bearing so that the position of the bearing is limited. In this way, the position of the bearing is not easy to move during the processing, so as to avoid the welding equipment from damaging the workbench and affecting the work efficiency of the staff.

[0035] The number of the extrusion blocks 44 is six, or other numbers, such as four or eight. The extrusion blocks 44 fit closely with the conical movable block 47, so that when the movable block 47 moves upward under the push of the hydraulic push rod 46, the extrusion blocks 44 move outward under the restriction of the connecting plate 43 so that the pad 42 clamps the bearing.

[0036] To control the outward movement of the pad to avoid damage to the bearing, such as Figure 5 As shown, a pressure sensor 48 is provided on the outer wall of the pad, a test plate 411 is provided on the outer side of the arc where the pad is located, and the test plate is also an arc-shaped plate. Two plug rods 49 are fixed on the inner wall of the test plate, and the first end of the plug rod is fixedly connected to the test plate, and the second end of the plug rod penetrates into the side wall of the pad and is slidably connected to the pad. A spring 410 is provided between the pad and the test plate, and under the action of the spring, there is a certain distance between the test plate and the pad.

[0037] The pressure sensor is connected to the controller signal, and the controller is connected to the hydraulic push rod solenoid valve signal. The pressure sensor 48 on the outside of the pad 42 can detect the pressure data between the pad 42 and the bearing, and transmit a signal to the controller of the processing equipment when the pressure data exceeds the set value, thereby stopping the extension of the hydraulic push rod 46 to prevent excessive extrusion force from causing damage to the composite plastic tile 6 and the bearing. At this time, the test plate is in direct contact with the inner wall of the bearing, and the extrusion force between the test plate and the bearing is transmitted to the pad under the action of the spring.

[0038] In order to solve the problem that the composite plastic tile 6 is easy to slide on the inner side of the metal steel back 3 and cause position deviation during the process of welding the composite plastic tile 6 on the inner side of the metal steel back 3, a limiting mechanism can be provided on the pad. The setting of the limiting mechanism makes it easy to fix the position of the composite plastic tile 6 on the metal steel back 3 even if there are differences in the width of the composite plastic tile 6.

[0039] like Figure 6 to Figure 7As shown, when the staff is welding the composite plastic tile 6 to the inner side of the metal steel back 3, they can first place the composite plastic tile 6 on the inner side of the metal steel back 3, and after aligning the composite plastic tile 6 with the installation position, use the limiting mechanism to limit the position of the composite plastic tile. The limiting mechanism includes a sliding block 71, a nut 72, a limiting block 73 and a screw 74. A screw 74 is fixed on the pad. The middle part of the screw penetrates into the side wall of the pad, and the two ends of the screw respectively pass through the pad and extend to both sides of the pad. The axis of the cylindrical surface where the pad is located is set parallel to the screw, and the screw passes through the end face of the pad. A sliding block 71 is provided at each end of the screw, and the sliding block can move along the axial direction of the screw. A nut 72 is provided at each end of the screw, and the sliding block is placed between the nut and the pad, and the nut is threadedly connected to the screw. The position of the sliding block on the screw can be adjusted by rotating the nut. A limit block 73 is fixed at the bottom of the sliding block. The two limit blocks are used to cooperate with each other and contact the composite plastic tile to achieve the clamping and limiting of the composite plastic tile. In this way, the composite plastic tile 6 can be kept fixed in position under the extrusion of the backing plate 42 and the clamping limit of the limit block 73. The limit block 73 can slide relative to the screw 74. According to the width of the composite plastic tile 6, the position of the limit block relative to the screw is adjusted, which is convenient for the staff to adjust and fix the position of the composite plastic tile 6. The sliding block, the screw and the nut constitute an adjustment unit for adjusting the relative position between the limit block and the backing plate.

[0040] When the staff uses the limit block 73 on the sliding block 71 to adjust the position of the composite plastic tile 6, the composite plastic tile 6 is always squeezed by the pad 42 and will not fall off. In addition, the area of ​​the sliding block 71 is small and does not affect the staff's welding work on the composite plastic tile 6.

[0041] During the welding process of the composite plastic tile 6, the fume generated by the welding contains a lot of harmful substances. After the harmful substances are diffused in the air and inhaled by the workers, they are likely to cause adverse effects on the health of the workers.

[0042] like Figure 1 and Figure 8As shown, a purification mechanism is provided on the outer wall of the lower part of the welding machine, and the purification mechanism includes a purification box 51, an activated carbon plate 52 arranged in the purification box, an exhaust fan 53 arranged at the bottom of the inner cavity of the purification box, a buzzer 55 arranged on the outer wall of the upper part of the purification box, and an air quality detector 56 arranged at the upper part of the inner cavity of the purification box. The bottom of the purification box is provided with an air inlet connected to the inner cavity of the purification box. When the staff is welding the composite plastic tile 6, the exhaust fan 53 can absorb the smoke generated by welding into the purification box 51 through the air inlet, and filter out the harmful substances contained in the interior when passing through the position of the activated carbon plate 52, and then discharge it through the top of the purification box without causing adverse effects on the health of the staff. There are multiple activated carbon plates arranged at equal intervals, and a baffle 54 is provided between the air quality detector and the top activated carbon plate. The baffle can isolate the contact between the activated carbon plate 52 and the air quality detector 56, and prevent the stains on the activated carbon plate 52 from affecting the detection accuracy of the air quality detector 56. The air quality detector 56 can detect the filtered air, and transmit a signal to the controller of the processing equipment when it detects that the air quality does not meet the standard, and then control the buzzer 55 to beep, informing the staff to replace the internal activated carbon plate 52 in time to prevent affecting the air purification effect. The controller is connected to the buzzer signal and also to the air quality detector signal.

[0043] In order to limit the position of the composite plastic tile 6 , the thickness of the limiting block 73 is the same as the thickness of the composite plastic tile 6 .

[0044] The working principle and use process of the present invention are described below: when the bearing processing equipment is processing the bearing, the bearing sleeve is arranged on the outside of the adjustment box 41, so that the staff operates the processing equipment to control the hydraulic push rod 46 to push the movable block 47 upward, so that the movable block 47 pushes the extrusion block 44 to move outward, thereby making the pad 42 expand outward, and the arc-shaped pad 42 can fit tightly with the inner wall of the circular bearing to define the position of the bearing, and it is not easy to move during the processing, thereby avoiding the situation where the welding equipment causes damage to the workbench and affects the work efficiency of the staff. When the staff is welding the composite plastic tile 6 to the inner side of the metal steel back 3, the composite plastic tile 6 can be placed on the inner side of the metal steel back 3, and after aligning the composite plastic tile 6 with the installation position, the composite plastic tile 6 can be used The nut 72 on one side of the pad 42 adjusts the position of the sliding block 71 on the screw 74 so that the limit block 73 at the lower end of the sliding block 71 is tightly fitted with one side of the composite plastic tile 6, and then the nut 72 on the other side of the pad 42 is adjusted to clamp the composite plastic tile 6, so that the composite plastic tile 6 remains relatively fixed under the squeezing of the pad 42 and the restriction of the limit block 73. The limit block 73 can slide on the screw 74 to facilitate adjustment according to the width of the composite plastic tile 6, so that the staff can fix the position of the composite plastic tile 6. When the staff is welding the plastic tile 6, the exhaust fan 53 can absorb the smoke generated by welding into the purification box 51, and filter out the harmful substances contained in the interior when passing through the position of the activated carbon plate 52 and then discharge it, which will not cause adverse effects on the health of the staff.
