Technical Field

[0002] The car bottom bracket is usually composed of multiple parts, which together form the support structure of the bottom of the car. Common car bottom bracket parts include: cross beam: The cross beam is the main load-bearing structure of the bottom of the car, usually made of steel, responsible for bearing the weight of the car itself and the weight of the passengers or goods carried, longitudinal beam: The longitudinal beam is located on the long side of the bottom of the car and is connected to the cross beam, which increases the stability and strength of the bottom structure. The car bottom bracket is an important part of the elevator or lift. Its processing accuracy directly affects the safety and performance of the elevator. Therefore, during the processing, the car bottom bracket needs to be accurately positioned on the processing equipment to ensure that each step of processing can be carried out according to the design requirements.

Many elevators in shapes such as round, arc, fan or polygon have emerged. When welding and positioning the arc-shaped elevator bottom bracket, it is more difficult to clamp the arc-shaped support beam compared to the square support beam because some of its support beams are arc-shaped.

[0015] The present invention has the following beneficial effects:

[0016] (1) The present invention aims to solve the problem that support beams with different curvatures are difficult to clamp. A moving plate 1 is arranged inside the device. When the moving plate 1 and the moving frame move, they will drive spring 2 and spring 3 to move respectively. Spring 2 will drive clamp block 1 to move through the moving plate 2. Spring 3 will drive clamp block 2 to move through the moving plate 3. Clamp block 1 and clamp block 2 will drive the rubber clamp block to move together. When the rubber clamp block contacts the curved surface of the support beam, the two rubber clamp blocks will drive the two support beams closer to each other. If the rubber clamp block does not fit the curved surface of the support beam, the moving frame will continue to move and pull spring 3, so that clamp block 2 will continue to move and pull the rubber The two sides of the clamping block cause it to deform, so that the rubber clamping block fits the arc surface of the support beam. After the two support beams are in contact at the welding point, if the support beam has a small angle of deflection, the deflection angle will disappear through the clamping and mutual squeezing of the two support beams. This design is suitable for support beams with different curvatures, and the support beams can be positioned twice to make the welding point of the two support beams fit more accurately. In the welding process, due to the action of spring two and spring three, the rubber clamping block continues to apply clamping force to the support beam, so that the weld melted during the welding process can be in close contact, reducing the gap generated at the weld after welding is completed.

[0017] (2) The present invention starts a motor to drive the double-headed threaded rod to rotate. The rotation of the double-headed threaded rod will drive the two moving plates 1 to approach each other. The moving plate 1 will drive the connecting rod to move through the moving frame. The connecting rod will drive the sliding rod to move through the fixed plate 1. Before the positioning rod contacts the support beam, the sliding rod will drive the sliding sleeve rod to move through the spring 1. The movement of the sliding sleeve rod will squeeze the air in the cavity inside the table body and pass into the fixed column 1 through the air guide tube 1. The air passed into the fixed column 1 will push the telescopic rod to move toward the center of the table body. The telescopic rod will drive the rotating rod 1 to move through the connecting plate 1. The rotating rod 1 will pull the rotating rod 2 The positioning rod is driven to rotate, so that the positioning rod contacts the support beam and the support beam is auxiliary clamped and positioned. After the positioning rod contacts the support beam, the sliding sleeve rod will no longer be pulled by spring 1, and the continued movement of the sliding rod will stretch spring 1 to give the sliding rod space to continue to move, thereby not hindering the continued movement of the fixed plate 1. This design can adjust the position of the support beam before clamping, perform preliminary positioning of the support beam, and ensure that the subsequent clamping is carried out normally. It can also automatically adjust the rotation angle of the positioning rod so that the positioning rod is always in contact with the support beam, and can be applied to support beams of different sizes within a certain range.

[0018] (3) In the process of clamping the support beam by the rubber clamp of the present invention, the extrusion rod will first contact the support beam. As the rubber clamp moves, the extrusion rod will be squeezed and compressed into the rubber clamp and push the air in the clamp 2 into the fixed column 2 through the air guide tube 2. The air pushed into the fixed column 2 will push the sliding plate and compress the spring 4, and then the air in the fixed column 2 will push the lower pressure plate downward through the fixed ring, and finally the bottom of the sliding wheel will contact the top of the support beam. The sliding wheel can make the downward pressure of the lower pressure plate only have a downward force, and cannot drive the support beam to move by friction. This design can press the support beam downward so that the welding point of the two support beams is in the same horizontal plane, preventing the two sides of the two support beams from slightly tilting up due to the excessive clamping force of the rubber clamp during welding, thereby affecting the quality of welding.

[0019] (4) When the lower pressure plate of the present invention descends, it will also drive the connecting plate 2 to move together through the fixing rod 2. After the connecting plate 2 moves downward, the fixing rod 1 will also move downward due to gravity, and finally the protective plate will fit with the top of the rubber clamp. The lowering of the lower pressure plate will compress the spring 5 through the connecting plate 2, thereby making the protective plate fit tightly with the rubber clamp. The protective plate is limited by the fixing plate 2 and the clamp 2, so that the clamp 2 can drive the rubber clamp to deform while also driving the protective plate to move, so that the protective plate is always in contact with the top of the rubber clamp. This design can prevent the sparks generated during the welding process from splashing onto the rubber clamp near the welding point, causing damage to the rubber clamp, thereby increasing the service life of the device.

[0043] A specific application of the present embodiment is as follows: when using the present device, first move the present device to a suitable position, then adjust the two arc-shaped support beams 119 to the position shown in the component 1 according to the figure, place the positions to be welded opposite to each other on the top of the table body 101, then start the motor 102 to drive the double-headed threaded rod 103 to rotate, the rotation of the double-headed threaded rod 103 will drive the two moving plates 104 to approach each other, the moving plate 104 will drive the connecting rod 107 to move through the moving frame 105, the connecting rod 107 will drive the sliding rod 109 to move through the fixed plate 108, before the positioning rod 118 contacts the support beam 119, the sliding rod 109 will drive the sliding sleeve rod 111 to move through the spring 110, the movement of the sliding sleeve rod 111 will squeeze the air in the internal cavity of the table body 101 and pass into the fixed column 113 through the air guide tube 112, the air passed into the fixed column 113 will push the telescopic rod 114 into the table body 101 The telescopic rod 114 will drive the rotating rod 116 to move through the connecting plate 115, and the rotating rod 116 will drive the positioning rod 118 to rotate by pulling the rotating rod 117, so that the positioning rod 118 contacts the support beam 119, and the support beam 119 is auxiliary clamped and positioned. After the positioning rod 118 contacts the support beam 119, the sliding sleeve rod 111 will no longer be pulled by the spring 110, and the sliding rod 109 continues to move to stretch the spring 110 to give the sliding rod 109 space to continue to move, thereby not hindering the fixed plate 108 from continuing to move. This design can adjust the position of the support beam 119 before clamping, perform preliminary positioning of the support beam 119, and ensure that the subsequent clamping is normal, and can automatically adjust the rotation angle of the positioning rod 118, so that the positioning rod 118 is always in contact with the support beam 119, and can be applicable to support beams 119 of different sizes within a certain range.

[0044] In the above process, the moving plate 104 and the moving frame 105 will respectively drive the spring 207 and the spring 3 208 to move when they move, the spring 207 will drive the clamp 1 202 to move through the moving plate 204, and the spring 3 208 will drive the clamp 2 203 to move through the moving plate 3 205, and the clamp 1 202 and the clamp 2 203 will drive the rubber clamp 201 to move together. When the rubber clamp 201 contacts the arc surface of the support beam 119, the two rubber clamps 201 will drive the two support beams 119 to move closer to each other. If the rubber clamp 201 does not fit the arc surface of the support beam 119, the moving frame 105 will continue to move and pull the spring 3 208, so that the clamp 2 203 continues to move and pulls the rubber clamp 2 01 on both sides to deform, so that the rubber clamp 201 and the arc surface of the support beam 119 are fitted. After the two support beams 119 are in contact at the welding point, if the support beam 119 has a small angle of deflection, the deflection angle will disappear by clamping and squeezing the two support beams 119. This design is suitable for support beams 119 with different curvatures, and the support beam 119 can be repositioned to make the welding point of the two support beams 119 fit more accurately. In addition, during the welding process, due to the action of the second spring 207 and the third spring 208, the rubber clamp 201 continues to apply a clamping force to the support beam 119, so that the welded part melted during the welding process can be in close contact, reducing the gap generated at the welded part after the welding is completed.

[0045] When the rubber clamp 201 clamps the support beam 119, the extrusion rod 301 will first contact the support beam 119. As the rubber clamp 201 moves, the extrusion rod 301 will be squeezed into the rubber clamp 201 and push the air in the clamp 203 into the fixed column 203 through the air guide 302. The air pushed into the fixed column 203 will push the sliding plate 305 and compress the spring 4 306, and then push the air in the fixed column 203 through the fixing ring 307. The pressing plate 308 is pushed downward, and finally the bottom of the sliding wheel 309 contacts the top of the support beam 119. The sliding wheel 309 can make the pressing plate 308 only have a downward force, and cannot drive the support beam 119 to move by friction. This design can press the support beam 119 downward, so that the welding points of the two support beams 119 are on the same horizontal plane, preventing the two sides of the two support beams 119 from slightly tilting due to the excessive clamping force of the rubber clamp 201 during the welding process, thereby affecting the quality of welding.

[0046] When the lower pressure plate 308 descends, it will also drive the connecting plate 205 to move together through the fixing rod 206. After the connecting plate 205 moves downward, the fixing rod 103 will also move downward due to gravity, and finally the protective plate 402 will fit the top of the rubber clamp 201. The lower pressure plate 308 will descend and compress the spring 5 404 through the connecting plate 205, so that the protective plate 402 and the rubber clamp 201 are tightly fitted. The protective plate 402 is limited by the fixing plate 201 and the clamp 203, so that the clamp 203 can drive the rubber clamp 201 to deform while also driving the protective plate 402 to move, so that the protective plate 402 is always fitted on the top of the rubber clamp 201. This design can prevent the sparks generated in the welding process from splashing onto the rubber clamp 201 near the welding point during welding, causing damage to the rubber clamp 201, thereby improving the service life of the device.
