Description

Technical Field

[0001] This invention relates to a clamping device, and more particularly to a heavy-duty sponge titanium consumable electrode clamping device. Background Technology

[0002] When welding existing sponge titanium consumable electrodes, the electrode blocks need to be clamped by a special clamping device first. After clamping multiple electrode blocks by the clamping device, the electrode blocks and the clamping device are sent into the vacuum welding equipment for automatic welding. The existing sponge titanium consumable electrode clamping device mainly includes left and right turntables and a middle beam. Multiple perforated plates are welded on the upper and lower sides of the middle beam (the number of perforated plates can be determined according to the number of electrode blocks combined). In use, the clamping device is hoisted onto the automatically stacked electrode block roller conveyor by a crane. It is first axially tightened using a jack or axially tightened using a tie rod (generally a tie rod is used for small tonnage). In order to ensure that the electrode blocks do not slip radially when the clamping device rotates during the welding process, pressure plates need to be installed at each perforated plate position on the middle beam, and wedges need to be manually driven in to clamp the electrode blocks. After the above work is completed, the clamping device and the clamped electrode blocks are sent into the vacuum welding equipment together. Multiple electrode blocks are welded together by the vacuum welding equipment. After the welding is completed and the electrode blocks are taken out of the furnace, the wedges and pressure plates need to be manually removed, and the welded electrode blocks need to be detached from the clamping device.

[0003] In order to ensure the stability of the electrode block clamping, the existing clamping device requires the installation of pressure plates at each perforated plate position on the intermediate beam and the manual insertion of wedges. Since sponge titanium consumable electrodes are generally welded together from thirty or forty electrode blocks, a wedge needs to be inserted at the corresponding position of each electrode block. This operation is time-consuming and labor-intensive. It usually takes about fifty minutes for two people to complete the clamping of a set of sponge titanium electrode blocks. The efficiency is low and the labor cost is high. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of the prior art and provide a heavy-duty sponge titanium consumable electrode clamping device.

[0005] The objective of this invention is achieved through the following technical solution: a heavy-duty sponge titanium consumable electrode clamping device, comprising two oppositely arranged turntables and a sliding frame, with a middle beam between the two turntables, and a plurality of guide sleeves respectively provided on the two middle beams, the guide sleeves being arranged sequentially along the length direction of the middle beam; a longitudinal sliding block is slidably connected in the guide sleeve; the sliding frame is located on one side of the middle beam, and a translation drive mechanism is provided between one end of the sliding frame and one of the turntables, the translation drive mechanism driving the sliding frame to move along the axial direction of the middle beam; the sliding frame is provided with a transverse sliding block corresponding to the longitudinal sliding block, the transverse sliding block is provided with a first inclined surface, one end of the longitudinal sliding block is provided with a second inclined surface, the first inclined surface contacting the second inclined surface.

[0006] In use, the electrode blocks are arranged between two intermediate beams, with longitudinal sliding blocks positioned on either side of the electrode blocks. A translational drive mechanism drives a sliding frame to move in one direction. During this movement, the sliding frame simultaneously moves a transverse sliding block. As the transverse sliding block moves, the cooperation of the first and second inclined surfaces causes the longitudinal sliding block to move towards the electrode blocks, clamping them tightly against their sides. This invention allows for the simultaneous and rapid clamping of multiple electrode blocks, making operation convenient, improving work efficiency, and reducing labor costs.

[0007] Preferably, the longitudinal sliding block is provided with a fixing block, and a return spring is provided between the fixing block and the guide sleeve. By providing a return spring between the fixing block and the guide sleeve, when the electrode block is released, the sliding frame is driven to move in the opposite direction by the translation drive device, and the return spring causes the longitudinal sliding block to automatically move away from the electrode block and release the electrode block.

[0008] Preferably, the guide sleeve is disposed on the upper and lower sides of the intermediate beam, and the sliding frame includes two parallel sliding rods with a connecting rod between the ends of the sliding rods. A transverse slider is disposed on the sliding rods. When clamping the sponge titanium consumable electrode, the translation drive mechanism pulls the sliding rods to move and tighten them, which in turn drives the transverse slider to move, which in turn drives the longitudinal slider to move and clamp the sponge titanium consumable electrode.

[0009] Preferably, the translation drive mechanism includes a lead screw and a threaded hole on a connecting rod. The lead screw is rotatably connected to the turntable, and the lead screw is connected to the threaded hole on the connecting rod. The sliding frame is moved by rotating the lead screw.

[0010] Preferably, the intermediate beam is provided with a back plate, and a constraint plate is connected to the back plate. The back plate, the constraint plate and the intermediate beam together form a constraint groove for constraining the slide rod, and the slide rod is connected in the constraint groove.

[0011] Preferably, the angle between the first inclined plane and the axial direction of the intermediate beam is 20 to 30 degrees.

[0012] Preferably, the slide bar is made of metal material, and one end of the slide bar is provided with an adjusting body. The adjusting body includes two C-shaped bodies, one end of which is connected. The adjusting body is S-shaped in general. The C-shaped body is composed of an outer material layer and an inner material layer. Both the outer material layer and the inner material layer are made of metal material. The coefficient of thermal expansion of the outer material layer is greater than that of the inner material layer.

[0013] The adjusting body has an overall "S" shape, which gives it a certain degree of elasticity in the length direction. When clamping the electrode block, the adjusting body deforms under the tension of the sliding rod when the translation drive mechanism applies a pulling force, causing both ends of the adjusting body to be stretched. This elastic deformation allows the adjusting body to store a certain amount of elastic potential energy (at this time, the adjusting body acts like a spring). The presence of the adjusting body ensures that the sliding rod is in a stable tensioned state. Even if the lead screw loosens to a certain extent, the adjusting body can play an adjustment role in the middle. By utilizing the tensile deformation of the adjusting body, the sliding rod is kept in a tensioned state, thus preventing clamping failure of the electrode block. Secondly, the electrode block is fed into the welding equipment for... During welding, the electrode block temperature rises due to the welding process. This temperature rise is transferred to the sliding rod via heat transfer, causing the sliding rod to heat up, and consequently, the regulating body. As the regulating body temperature rises, the inner material layer of the C-shape has a higher coefficient of thermal expansion than the outer material layer, resulting in greater thermal expansion of the outer layer than the inner layer. This reduces the distance between the openings at both ends of the C-shape, thus decreasing the overall axial length of the regulating body. This further tightens the sliding rod, increasing the clamping force on the electrode block and improving the clamping effect during welding. This prevents the electrode block from loosening during welding, ensuring the welding quality. After welding, the regulating body gradually cools to room temperature and returns to its initial state. The regulating body consists of two C-shapes with opposite opening directions. This asymmetrical arrangement has the advantage that when the regulating body deforms due to temperature rise, it counteracts the movement of the ends of the two C-shapes in the direction perpendicular to the length of the regulating body, allowing the ends to move linearly during deformation.

[0014] The beneficial effects of this invention are: it can quickly clamp multiple electrode blocks simultaneously, making it more convenient to operate, improving work efficiency, and reducing labor costs. Attached Figure Description

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention are within the scope of protection of the present invention.

[0024] Example 1:

[0025] like Figures 1 to 4 As shown, a heavy-duty sponge titanium consumable electrode clamping device includes two opposing turntables 1 and a sliding frame. Two intermediate beams 2 are provided between the two turntables 1, and the two intermediate beams 2 are parallel to each other. Several guide sleeves 3 are provided on each of the two intermediate beams 2, and the guide sleeves 3 are arranged sequentially along the length of the intermediate beams 2. A longitudinal sliding block 6 is slidably connected to each guide sleeve 3, and the longitudinal sliding block 6 can move radially along the turntables 1.

[0026] The sliding frame is located on one side of the intermediate beam 2. A translation drive mechanism is provided between one end of the sliding frame and one of the turntables 1. The translation drive mechanism drives the sliding frame to move along the axial direction of the intermediate beam 2. The sliding frame is provided with a transverse slider 9 corresponding to the longitudinal slider 6. The transverse slider 9 is provided with a first inclined surface 14, and one end of the longitudinal slider 6 is provided with a second inclined surface. The first inclined surface 14 contacts the second inclined surface. In this embodiment, the angle between the first inclined surface 14 and the axial direction of the intermediate beam 2 is 20 to 30 degrees.

[0027] The guide sleeve 3 is located on the upper and lower sides of the intermediate beam 2. The sliding frame includes two parallel sliding rods 5, with a connecting rod 4 between the ends of the sliding rods 5. The transverse slider 9 is mounted on the sliding rods 5. The translation drive mechanism includes a lead screw 12 and a threaded hole 13 on the connecting rod 4. The lead screw 12 is rotatably connected to the turntable 1 and can rotate around its own central axis, but cannot move axially relative to the turntable 1. The lead screw 12 is connected to the threaded hole 13 on the connecting rod 4. Rotating the lead screw 12 drives the sliding frame to move.

[0028] A back plate 7 is provided on the intermediate beam 2, and a constraint plate 8 is connected to the back plate 7. The back plate 7, the constraint plate 8, and the intermediate beam 2 together form a constraint groove for constraining the slide rod 5, and the slide rod 5 is connected in the constraint groove. Under the constraint of the back plate 7, the constraint plate 8, and the intermediate beam 2, the slide rod 5 moves along the axial direction of the intermediate beam 2.

[0029] A fixing block 10 is provided on the longitudinal slider 6, and a return spring 11 is provided between the fixing block 10 and the guide sleeve 3.

[0030] In use, the electrode blocks 15 are arranged and placed between two intermediate beams 2. The longitudinal sliding blocks 6 are positioned on either side of the electrode blocks 15. A translational drive mechanism drives the sliding frame to move in one direction. During this movement, the sliding frame moves the sliding rod 5 and tightens it. The sliding rod 5 then drives the transverse sliding block 9 to move. As the transverse sliding block 9 moves, the cooperation of the first inclined surface 14 and the second inclined surface causes the longitudinal sliding block 6 to move towards the electrode blocks 15 and press against both sides of the electrode blocks 15, thus clamping the electrode blocks 15. When releasing the electrode blocks 15, the translational drive mechanism drives the sliding frame to move in the opposite direction. A return spring 11 automatically moves the longitudinal sliding block 6 away from the electrode blocks 15, releasing them. This invention can simultaneously and quickly clamp multiple electrode blocks 15, making operation convenient, improving work efficiency, and reducing labor costs.

[0031] Example 2:

[0032] like Figure 5-7 As shown, the difference between Embodiment 2 and Embodiment 1 is that in Embodiment 2, the slide rod is made of metal material, and one end of the slide rod is provided with an adjusting body 16. The adjusting body 16 includes two C-shaped bodies 161, one end of which is connected. The adjusting body 16 is generally S-shaped. The C-shaped body 161 is composed of an outer material layer 1611 and an inner material layer 1612. Both the outer material layer 1611 and the inner material layer 1612 are made of metal material. The coefficient of thermal expansion of the outer material layer 1611 is greater than that of the inner material layer 1612.

[0033] The adjusting body 16 has an overall "S"-shaped structure. This structure gives the adjusting body 16 a certain degree of elasticity in the length direction. When clamping the electrode block 15, when the translation drive mechanism applies a pulling force to the slide rod, the adjusting body 16 can deform under the action of the pulling force, causing both ends of the adjusting body 16 to be stretched. The adjusting body undergoes elastic deformation, allowing the adjusting body 16 to store a certain amount of elastic potential energy (at this time, the adjusting body acts like a spring). The presence of the adjusting body 16 ensures that the slide rod 5 can be in a stable tensioned state. Even if the lead screw loosens to a certain extent, the adjusting body can play an adjustment role in the middle. By using the tension deformation state of the adjusting body, the slide rod is always kept in a tensioned state, thereby avoiding clamping failure of the electrode block 15. Secondly, when the electrode block 15 is fed into the welding equipment for welding, by During the welding process, the temperature of electrode block 15 rises. This rise in temperature transfers heat to the slide rod 5, causing its temperature to rise, which in turn raises the temperature of the adjusting body 16. As the adjusting body 16 heats up, the thermal expansion coefficient of the inner material layer on the C-shaped body 161 is greater than that of the outer material layer. This results in the outer material layer 1611 expanding more than the inner material layer 1612, thus reducing the distance between the two openings of the C-shaped body 161. Consequently, the overall axial length of the adjusting body 16 decreases, further tightening the slide rod 5 and increasing the clamping force on the electrode block 15. This improves the clamping effect of the electrode block during welding, preventing it from loosening and ensuring the welding quality. After welding, the adjusting body gradually cools to room temperature and returns to its initial state. The regulating body consists of two C-shaped bodies with their openings facing opposite directions. The advantage of this asymmetrical arrangement is that when the regulating body deforms due to temperature rise, it can offset the movement of the ends of the two C-shaped bodies 161 in the direction perpendicular to the length of the regulating body, so that when the regulating body 16 deforms due to temperature, its two ends move along a straight line to stretch and contract.

[0034] The remaining structures of Example 2 are the same as those of Example 1.

[0035] This invention is not limited to the preferred embodiments described above. Anyone can derive other products in various forms under the guidance of this invention. However, regardless of any changes in shape or structure, any technical solution that is the same as or similar to this application falls within the protection scope of this invention.
