Detailed Implementation

[0083] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with those of this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the embodiments of this application as detailed in the appended claims.

[0084] The technical solutions of the embodiments of this application and how the technical solutions of the embodiments of this application solve the current problems are described in detail below with specific examples. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0085] Please see Figures 1-3 This application provides a variable position vise type tooling, including: at least one clamping vise 1, a crossbeam 2, two rotating mechanisms 3 and two columns 4;

[0086] The clamping vise 1 is used to clamp the workpiece;

[0087] The clamping vise 1 is fixed on the crossbeam 2;

[0088] Both ends of the crossbeam 2 are respectively connected to one of the rotating mechanisms 3;

[0089] The rotating mechanism 3 is used to rotate the crossbeam 2;

[0090] One of the rotating mechanisms 3 is mounted on one of the columns 4.

[0091] In this example, the workpiece is fixed by a clamping vise, and the workpiece is rotated by a rotating mechanism to rotate the crossbeam. This allows the worker to perform continuous welding on the flipped workpiece without moving, ensuring both welding quality and efficiency.

[0092] By setting the column 4, the clamping vise 1 is positioned at a specified height, making it easier for workers to perform welding operations on the workpiece.

[0093] In a preferred embodiment, the clamping vise 1 includes: a fixed vise body 11, a vise base 12, a lead screw 13, a guide nut (not shown in the figure), a movable vise body 14, and a crank handle 15;

[0094] The fixed clamp body 11 is fixed on the bench vise base 12, and the bench vise base 12 is fixed on the crossbeam 2;

[0095] One end of the lead screw 13 is rotatably connected to the fixed clamp body 11;

[0096] The guide nut is screwed onto the lead screw 13, and the movable clamp body 14 is connected to the guide nut;

[0097] The end of the lead screw 13 away from the fixed clamp body 11 is connected to the crank handle 15.

[0098] In this example, the movable jaw 14 is mounted on the fixed jaw 11 and is driven to move within the groove of the fixed jaw 11 by a lead screw 13 with a trapezoidal thread, thereby enabling the jaws to open and close. The design of the movable jaw 14 allows it to move flexibly within the fixed jaw 11 to accommodate workpieces of different sizes.

[0099] The fixed jaw 11 is connected to the vise base 12, serving to support and fix the movable jaw 14. The fixed jaw 11 is usually equipped with jaw bars (clamping surfaces) for clamping workpieces. The jaw bars are formed with diamond-shaped teeth to increase clamping force and prevent workpiece slippage.

[0100] The vise base 12 is the support part of the vise, which is fixed to the workbench by bolts. The design of the vise base 12 allows the vise to be placed stably on the workbench and to withstand various forces during the workman's operation.

[0101] Lead screw 13: Lead screw 13 passes through the hole in the movable jaw body 14. One end is restrained on the movable jaw body by a washer, and the other end is screwed into the guide nut. The lead screw 13 has a trapezoidal thread. When the crank handle 15 is rotated, the lead screw 13 moves back and forth in the guide nut, and drives the movable jaw body to move accordingly in the fixed jaw body.

[0102] Guide nut: The guide nut is mounted on the fixed clamp body and works in conjunction with the lead screw 13 to enable the movement of the movable clamp body 14.

[0103] Handle 15: Handle 15 is used to rotate the lead screw 13, thereby moving the movable vise 14. The design of handle 15 allows the fitter to easily operate the vise to clamp or release workpieces.

[0104] In a preferred embodiment, the crossbeam 2 includes: a cross plate 21, two support plates 22, and two end plates 23;

[0105] The vise seat 12 of the clamping vise 1 is fixed on the upper surface of the horizontal plate 21;

[0106] The upper side of the support plate 22 is connected to one side of the lower surface of the horizontal plate 21, and the two support plates 22 are symmetrically arranged on the lower surface of the horizontal plate 21.

[0107] One end plate 23 is connected to one end of the horizontal plate 21 and the two support plates 22, and the other end plate 23 is connected to the other end of the horizontal plate 21 and the two support plates 22;

[0108] The two end plates 23 are respectively connected to the two rotating mechanisms 3.

[0109] In this example, the stability of the beam 2 is ensured by setting the cross plate 21 and the support plate 22.

[0110] By setting the end plate 23, the firmness of the connection between the rotating mechanism 3 and the crossbeam 2 is ensured.

[0111] Optionally, four crossbeam reinforcement plates 24 are also included;

[0112] One of the beam reinforcement plates has two mutually perpendicular sides, one side is connected to the bottom side of the support plate 22, and the other side is connected to the surface of the end plate 23 facing the side of the cross plate 21.

[0113] In a preferred embodiment, the rotating mechanism 3 includes: a rotary reducer 31, a rotary motor (not shown in the figure), and a rotating base 32;

[0114] The rotary reducer 31 is connected to the end plate 23 of the crossbeam 2;

[0115] The rotary motor is connected to the rotary reducer 31;

[0116] The rotary reducer 31 and the rotary motor are fixed on the rotary base 32;

[0117] The rotating seat 32 is mounted on one of the columns 4.

[0118] In this example, by setting a rotary reducer 31, a sufficiently large torque is ensured to rotate the crossbeam 2, allowing workers to weld the workpiece in a more comfortable posture and angle, reducing worker fatigue, and improving the efficiency and quality of workpiece welding.

[0119] The rotary motor provides rotational torque to the rotary reducer 31.

[0120] The rotating seat 32 is set to mount the rotary reducer 31 and the rotary motor on the column 4. The height of the workpiece is determined by adjusting the position of the rotating seat 32 on the column 4.

[0121] Optionally, the rotation direction of the rotary motor includes forward and reverse rotation, and the rotation angle of the rotary reducer 31 includes: forward rotation 0°-90° and reverse rotation 0°-90°.

[0122] In this embodiment, the rotary motor is a three-phase motor to ensure sufficient tilting power for the crossbeam 2. The rotating base 32 has a shell-like structure, and the rotary reducer 31 and the rotary motor are fixed inside the rotating base.

[0123] The rotary reducer 31 is a worm gear reducer, a power transmission mechanism that uses a gear speed converter to reduce the motor's rotational speed to the required speed while obtaining a larger torque. Worm gear reducers can increase output torque while reducing speed. The torque output ratio is calculated by multiplying the motor output by the reduction ratio, but care must be taken not to exceed the reducer's rated torque. The reduction in speed also reduces the load's inertia; the reduction in inertia is equal to the square of the reduction ratio. Worm gear reducers typically have a compact mechanical structure, are small in size, and highly efficient. They also have good heat exchange performance and rapid heat dissipation, which helps maintain stable operation of the reducer.

[0124] In a preferred embodiment, the column 4 includes: two upright plates 41, two column bases 42, and a column top plate 43;

[0125] The bottom end of one of the upright plates 41 is connected to one of the column bases 42;

[0126] One of the rotating mechanisms 3 is located between the two upright plates 41;

[0127] The top ends of the two upright plates 41 are connected to the lower surface of the column top plate 43.

[0128] In this example, the stability of the column 4 is improved by setting up the upright plate 41 to install the rotating mechanism 3 and by setting up the column base 42; the stability of the upright plate 41 and the rotating mechanism 3 installed on the upright plate 41 is ensured by setting up the column top plate 43 to connect the two upright plates 41.

[0129] In a preferred embodiment, it further includes: two height mechanisms 5;

[0130] One of the height-increasing mechanisms 5 is fixed to the upper surface of the column top plate 43 of the column 4;

[0131] One of the height-increasing mechanisms 5 is connected to one of the rotating mechanisms 3.

[0132] In this example, by setting up a height mechanism 5, the height of the crossbeam 2 can be adjusted by adjusting the rotation mechanism 3, thereby achieving the technical effect of adjusting the height position of the workpiece. This makes it easier for workers to adjust the height of workpieces of different sizes and specifications, further improving the convenience of workers welding workpieces and increasing the welding efficiency and quality.

[0133] In a preferred embodiment, the height mechanism 5 includes:

[0134] A height reducer 51, a height motor 52, a height seat 53, two fixed gears (not shown in the figure), two height gears 55, and two height chains 56;

[0135] The height reducer 51 is connected to the end plate 23 of the crossbeam 2;

[0136] The height motor 52 is connected to the height reducer 51;

[0137] The height reducer 51 and the height motor 52 are fixed on the height seat 53;

[0138] The height reducer 51 has two output ends, and each output end of the height reducer 51 is connected to a height gear 55.

[0139] The two fixed gear wheels are rotatably connected to the two upright plates 41 of the column 4;

[0140] One of the height chains 56 is fitted onto one of the height gears 55 and one of the fixed gear wheels;

[0141] The height chain 56 is connected to the rotating seat 32 of the rotating mechanism 3.

[0142] In this example, the height reducer 51 and the height motor 52 provide lifting power to the height chain 56. By connecting the height chain 56 to the rotating seat 32, when the height chain 56 rotates around the fixed gear and the height gear 55, it drives the rotating seat 32 to rise or fall with the rotation of the height chain 56, thereby achieving the technical effect of adjusting the height of the rotating mechanism 3. In this embodiment, a fixed gear is rotatably connected to the side of one vertical plate facing another vertical plate.

[0143] Optionally, the rotation direction of the height motor 52 includes forward and reverse rotation; when the height motor 52 rotates forward, the height reducer 51 will drive the rotating mechanism 3 to lift through the height chain 56; when the height motor 52 rotates in reverse, the height reducer 51 will drive the rotating mechanism 3 to descend through the height chain 56.

[0144] In this embodiment, the height motor 52 is a three-phase motor to ensure that sufficient turning power is provided to the crossbeam 2.

[0145] The height reducer 51 is a worm gear reducer, a power transmission mechanism that uses a gear speed converter to reduce the motor's rotational speed to the required speed while obtaining a larger torque. Worm gear reducers can increase output torque while reducing speed. The torque output ratio is calculated by multiplying the motor output by the reduction ratio, but care must be taken not to exceed the reducer's rated torque. The speed reduction also reduces the load's inertia; the reduction in inertia is equal to the square of the reduction ratio. Worm gear reducers typically have a compact mechanical structure, are small in size, and highly efficient. They have good heat exchange performance and rapid heat dissipation, which helps maintain stable operation. The two output ends of the height reducer 51 are the two ends of the worm in the worm gear reducer, therefore, the speeds of the two output ends can be kept synchronized.

[0146] In a preferred embodiment, it further includes: a positioning plate 6;

[0147] The positioning plate 6 is located on the side of the rotating mechanism 3 facing the crossbeam 2;

[0148] The positioning plate 6 is fixed on the rotating seat 32 of the rotating mechanism 3, and the positioning plate 6 is movably connected to the two upright plates 41 of the column 4.

[0149] The rotary reducer 31 of the rotary mechanism 3 passes through the positioning plate 6 and is connected to the end plate 23 of the crossbeam 2.

[0150] In this example, the stability of the rotating machine during lifting and lowering is ensured by setting the positioning plate 6.

[0151] In a preferred embodiment, it further includes: a foot switch 7;

[0152] One of the foot switches 7 is connected to the rotary motors of the two rotary mechanisms 3 respectively, and the foot switch 7 is used to trigger the start and stop of the two rotary motors.

[0153] In this example, the foot switch 7 is used to switch the circuit on and off by stepping on it, and can also be used to control the output current. The foot switch 7 is a switch that controls the circuit's on / off state by stepping on it, used in control circuits where the hands cannot reach, to replace the hands for operation. By incorporating the foot switch 7, it does not occupy the worker's hand space; therefore, the worker can easily perform workpiece flipping operations while holding the welding equipment, providing great convenience.

[0154] Optionally, the foot switch 7 is installed between the two column bases 42 of a column 4. When the worker steps on the foot switch 7, it controls the rotary motor in the rotating mechanism 3 to rotate forward and backward. This allows the clamped workpiece to be rotated at an angle of 0 to 90 degrees, assisting the worker in welding at the optimal angle.

[0155] In an optional embodiment, a rotating seat 32 of the rotating mechanism 3 is fixed between two upright plates 41 of the column 4.

[0156] In this example, by fixing the rotating seat 32 between the two upright plates 41, the crossbeam 2 can be brought close to the column 4, thereby reducing the length of the entire variable position vise fixture. The structure is simple, robust and reliable.
