Description

Technical Field

[0001] The utility model relates to the technical field of welding auxiliary equipment, in particular to an automatic clamping device for welding a support seat of a vibration screening device. Background Technique

[0002] Screening devices are generally used for screening ores and coals. The feed has a large specific gravity and large particle size, and at the same time bears high-intensity vibration and the impact of materials. And with the progress and development of technology, screening devices are gradually developing towards large-scale, which puts forward higher requirements for the design and manufacture of screening devices.

[0003] The screening device is completely supported and fixed by the support seat. Therefore, the support seat must be safe and reliable, and the welding quality must be guaranteed. The original manual welding method can no longer meet the development needs, and automated welding has become necessary.

[0004] The existing welding jigs are manually welded on the welding platform. The workpiece needs to be flipped multiple times during welding, and the welding efficiency is low. Moreover, the quality of manual welding is lower than that of robot welding. Content of the Utility Model

[0005] In order to improve the welding quality and efficiency of the support seat of the vibration screening device, the utility model provides an automatic clamping device for welding the support seat of the vibration screening device.

[0006] The automatic clamping device for welding the support seat of the vibration screening device provided by the utility model adopts the following technical scheme:

[0007] An automatic clamping device for welding a support seat of a vibration screening device is installed on a positioner for clamping and fixing the support seat. The clamping device includes a support frame, on which a cylinder, a slide rail and a sensor for sensing the position of the support seat and sending a signal to control the operation of the cylinder are installed. A slider with a slope is installed on the piston rod of the cylinder, and the slider is slidably connected to the slide rail for pressing and fixing the support seat.

[0008] By adopting the above technical scheme, the support seat is placed on the support frame. After the sensor senses the support seat, it controls the operation of the cylinder through a signal. The cylinder drives the slider to move along the slide rail, and the slider cooperates with the support frame to clamp and fix the support seat. Used in conjunction with the positioner, the one-key loading, automatic flipping and welding of the support seat are realized, thereby improving the welding efficiency and quality.

[0009] Optionally, the slider includes a mounting plate, the mounting plate is connected to the piston rod of the cylinder, and a pressing block for pressing the support seat is fixed on the mounting plate through fastening screws.

[0010] By adopting the above technical scheme, the pressing block is fixed on the mounting plate through fastening screws, and the convenient replacement operation of the pressing block can be realized.

[0011] Optionally, a sliding hole is formed in the support frame along the traveling direction of the slider. A pulling plate passing through the sliding hole is fixedly connected to the mounting plate. One end of the pulling plate away from the mounting plate is perpendicularly fixedly connected with a baffle plate, and the baffle plate is arranged in contact with the bottom surface of the support frame.

[0012] By adopting the above technical solution, the pulling plate, the baffle plate and the support frame cooperate with each other to offset the reverse acting force of the support seat on the pressing block, thereby reducing the risk of the cylinder piston rod being bent and damaged due to force.

[0013] In summary, the present utility model includes at least one of the following beneficial technical effects:

[0014] One-key clamping, automatic flipping and welding of the support seat are realized, thereby improving the welding efficiency and welding quality;

[0015] Convenient replacement operation of the pressing block is realized;

[0016] The risk of the cylinder piston rod being bent and damaged due to force is reduced. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The following further describes the present utility model in detail with reference to the attached Figure 1 - attached Figure 3 to the present utility model.

[0022] An embodiment of the present utility model discloses an automatic clamping device for welding the support seat of a vibrating screening device. Embodiment 1

[0023] Refer to Figure 1 and Figure 2, a vibration screening equipment support seat welding automatic clamping device, used for clamping and fixing the support seat 1. This clamping device includes a support frame 2, a cylinder 3, a slider 4, a slide rail 5, and a sensor 6. The cylinder 3 is installed on the support frame 2, and the slider 4 is installed at the end of the piston rod of the cylinder 3. The slider 4 is used to cooperate with the support frame 2 to clamp and fix the support seat 1.

[0024] Refer to Figure 1 and Figure 2 , the slider 4 includes a mounting plate 40, a pressing block 41, and a fastening screw 42. The mounting plate 40 is an L-shaped plate, and the mounting plate 40 is fixed to the end of the piston rod of the cylinder 3; the bottom of the pressing block 41 is provided with a slope, and the pressing block 41 is fixed in the mounting plate 40 through the fastening screw 42; the slide rail 5 is installed on the support frame 2, and a chute adapted to the slide rail 5 is opened on the pressing block 41. The pressing block 41 is slidably connected to the slide rail 5 through the chute; the sensor 6 is installed on the support frame 2, and the sensor 6 is used to sense the position of the support seat 1 and send a signal, thereby controlling the operation of the cylinder 3.

[0025] The implementation principle of Embodiment 1 is: after placing the support seat 1 on the four support frames 2, the sensor 6 is triggered to send an instruction. After the cylinder 3 receives the control signal of the system, it drives the slider 4 to move along the slide rail 5, thereby clamping and fixing the support seat 1. The whole clamping device is installed on the turntable of the welding robot system, which can realize one-key loading, automatic flipping and welding of the support seat 1, thus improving the welding efficiency and welding quality. Embodiment 2

[0026] Refer to Figure 3 , the difference between this embodiment and Embodiment 1 is that the slider 4 further includes a pull plate 43 and a baffle 44. A pull plate 43 is respectively arranged on both sides of the pressing block 41, and the pull plate 43 is fixedly connected to the mounting plate 40. Two sliding holes 20 are opened on the support frame 2 at positions corresponding to the two pull plates 43. The extending direction of the sliding holes 20 is the same as the moving direction of the slider 4. The pull plate 43 passes through the sliding holes 20, and the baffle 44 is vertically fixedly connected to one end of the two pull plates 43 away from the mounting plate 40. The baffle 44 is arranged in contact with the bottom surface of the support frame 2.

[0027] The implementation principle of Embodiment 2 is: during the process of clamping and fixing the support seat 1, the pull plate 43, the baffle 44 and the support frame 2 cooperate with each other to provide a downward acting force on the mounting plate 40 to offset the upward acting force of the support seat 1 on the pressing block 41, thereby reducing the risk of the piston rod of the cylinder 3 being bent and damaged due to force, and at the same time ensuring that sufficient pressure is applied to the support seat 1.
