Description

Technical Field

[0001] This utility model relates to the field of welding and grinding technology, and in particular to a steel wire welding scar grinding mechanism. Background Technology

[0002] Steel wire is used in several key areas of automobile manufacturing, where its high strength, corrosion resistance, and elasticity support the structural safety and performance optimization of vehicles. However, in the production of automotive parts using steel wire, there is often a shortage of remaining wire length. To reduce resource waste, these insufficiently long wires can be welded to meet the required length for use in applications with lower performance requirements. However, the weld beads produced after welding affect the wire's usability and appearance, necessitating grinding. The traditional method for grinding weld beads is manual, where workers use grinding pliers to clamp the weld bead and move it back and forth to remove it. However, this method has several drawbacks: inconsistent quality, low efficiency, and high labor costs. Utility Model Content

[0003] Therefore, in order to overcome the above-mentioned shortcomings, this utility model provides a steel wire welding scar grinding mechanism, comprising:

[0004] The clamp is provided with at least two sets of clamps, which are arranged opposite to each other. The steel wire is fixed by the at least two sets of clamps so that the weld bead is located between the two adjacent sets of clamps.

[0005] A grinder, which is disposed between two adjacent sets of the clamps;

[0006] The lifting mechanism drives the grinder to move linearly along the radial direction of the steel wire;

[0007] A rotating mechanism drives the grinder to rotate circumferentially along the steel wire.

[0008] This invention achieves fully automated grinding of weld beads through the coordinated action of clamping, lifting and rotating, reducing labor intensity. The grinding depth is controlled by the lifting mechanism, and the rotating mechanism ensures uniform grinding in the circumference, avoiding surface unevenness caused by manual operation.

[0009] Furthermore, the clamp includes:

[0010] A first clamping block, the surface of which has a V-shaped groove;

[0011] The second clamping block has a V-shaped block on its surface that matches the aforementioned V-shaped groove;

[0012] The locking mechanism drives the second clamping block to move, so that the steel wire is partially wrapped between the end of the V-shaped block and the bottom of the V-shaped groove.

[0013] Furthermore, a first slot is provided at one end of the first clamping block, and a third slot is provided at one end of the second clamping block corresponding to the first slot;

[0014] The locking mechanism includes:

[0015] A connecting block, which is installed in the first slot;

[0016] A locking bolt passes through a third slot and engages with the threaded connection hole.

[0017] Furthermore, the connecting block is pivotally connected to the first clamping block.

[0018] Furthermore, the first clamping block has a second slot at the end away from the first slot, and a clamping block at the end away from the third slot. The clamping block is embedded in the second slot and pivotally connected to the first clamping block.

[0019] Automatic alignment of the steel wire axis is achieved through the cooperation of the V-groove and V-block, and the accuracy of the grinder in grinding weld beads is improved by adjusting the locking mechanism.

[0020] Furthermore, the lifting mechanism includes:

[0021] Fixing plate;

[0022] The lead screw is rotatably mounted on the fixed plate;

[0023] The slider slides relative to the fixed plate and is threadedly engaged with the lead screw. The grinder is fixedly mounted on the slider.

[0024] The linear motion of the slider is driven by a lead screw, which improves the transmission response speed. The self-locking function of the lead screw reduces the probability of equipment failure. The lifting mechanism has a simple structure, few wear parts, and low replacement cost.

[0025] Furthermore, the rotating mechanism includes:

[0026] Installation Department;

[0027] The handwheel is rotatably mounted on the mounting part;

[0028] The turntable is rotated by turning a handwheel, and the fixing plate is fixedly installed on the turntable.

[0029] The mounting section and one side of the turntable have slits for inserting steel wires.

[0030] Furthermore, the rotating mechanism also includes:

[0031] A gear set that is connected to the handwheel;

[0032] A rack, which is fixed to the surface of the turntable around the edge of the turntable, meshes with the aforementioned gear set.

[0033] The turntable can be rotated by a handwheel drive combined with a gear and rack transmission, which can quickly adjust the circumferential position of the grinder and reduce the time spent on manual repositioning.

[0034] Furthermore, the rotating mechanism also includes a guide wheel assembly, which is fixedly mounted on the mounting part and contacts the circumferential side of the turntable.

[0035] By limiting the radial runout of the turntable through the guide wheel assembly, the rotational accuracy of the turntable is improved. The rotation of the turntable is guided by the rolling of the guide wheel assembly, which can reduce the friction between the turntable and the mounting part.

[0036] Furthermore, the grinding mechanism also includes a collection trough, which is disposed entirely below the steel wire between the two sets of clamps.

[0037] This collection tank allows for the collection of welding slag that has been ground down, preventing it from falling onto the ground and becoming difficult to clean.

The grinding depth is controlled by the lifting mechanism, and the rotation mechanism ensures uniform grinding in the circumferential direction, avoiding surface unevenness caused by manual operation.

[0055] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0056] In this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, without necessarily requiring or implying any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.

[0057] As described in the background section, the traditional method for grinding weld beads is manual grinding. Workers use grinding pliers to clamp the weld bead and move it back and forth to remove it. However, this method has many drawbacks. The quality of manual grinding is inconsistent, the grinding efficiency is low, and it consumes a lot of manpower, resulting in a heavy workload.

[0058] Example 1:

[0059] Therefore, in order to solve the above-mentioned technical problems existing in the prior art, this embodiment provides a steel wire welding scar grinding mechanism, such as... Figures 1-3 As shown, the polishing mechanism includes:

[0060] The clamp 50 is provided with at least two sets of clamps, which are arranged opposite to each other. The steel wire is fixed by the at least two sets of clamps so that the weld bead is located between the two adjacent sets of clamps.

[0061] A grinder 40 is disposed between two adjacent sets of the clamps;

[0062] The lifting mechanism 60 drives the grinder to move linearly along the radial direction of the steel wire.

[0063] The rotating mechanism 30 drives the grinder to rotate circumferentially along the steel wire.

[0064] In this embodiment, as Figure 2 As shown in the figure, the grinding mechanism has two sets of clamps, respectively set on both sides of the grinder. These clamps hold and fix the pre-set clamping points on both sides of the weld bead on the steel wire, keeping the steel wire stationary. A rotating mechanism drives the grinder to rotate, thereby controlling the angle of the grinder's vertical offset, allowing it to move or remain stationary in a suitable position to grind the weld bead, achieving rapid and aesthetically pleasing weld bead removal. Additionally, a lifting mechanism can drive the grinder to move linearly along the radial direction of the steel wire, allowing the grinder to move away from or closer to the steel wire, thus controlling the grinding depth. The structure of the grinder can be referenced... Figure 4 As shown, this grinder can use a structure of a motor and a milling cutter. The milling cutter is mounted on the motor shaft, and the motor drives the milling cutter to rotate. The rotating milling cutter grinds the weld beads.

[0065] This embodiment achieves fully automated grinding of weld beads through the coordinated action of clamping, lifting and rotating, reducing labor intensity. The grinding depth is controlled by the lifting mechanism, and the rotating mechanism ensures uniform grinding in the circumference, avoiding surface unevenness caused by manual operation and improving the aesthetics of the steel wire weld.

[0066] In addition, the grinding mechanism in this embodiment may also include a frame, and the clamp and rotating mechanism can be installed on the top of the frame. The frame provides installation space for the clamp, rotating mechanism and other components, and provides working height for the entire grinding mechanism. The frame can be designed according to actual working needs.

[0067] Exemplary, this embodiment provides one structure of the clamp, such as Figure 5 As shown, the clamp may include:

[0068] A first clamping block 51, the surface of which has a V-groove 51A;

[0069] The second clamping block 54 has a V-shaped block on its surface that matches the aforementioned V-shaped groove;

[0070] The locking mechanism drives the second clamping block to move, so that the steel wire is partially wrapped between the end of the V-shaped block and the bottom of the V-shaped groove.

[0071] For example, such as Figure 6 , 7 As shown, a first slot 51B is provided at one end of the first clamping block, and a third slot 54C is provided at one end of the second clamping block corresponding to the first slot;

[0072] like Figure 5 As shown, the locking mechanism includes:

[0073] Connecting block 53, which is installed in the first slot;

[0074] Locking bolt 52 passes through the third slot and engages with the threaded connection hole.

[0075] In this embodiment, rotating the bolt pushes the second clamping block to move, causing the V-shaped block to move closer to the V-shaped groove, forming a clamping force, thereby achieving the clamping and fixing of the steel wire.

[0076] For example, the connecting block may be pivotally connected to the first clamping block.

[0077] like Figure 6 , 7 As shown, a second slot 51C can be provided at the end of the first clamping block away from the first slot, and a card block 54B is provided at the end of the second clamping block away from the third slot. The card block is embedded in the second slot and pivotally connected to the first clamping block.

[0078] After the wire self-welding device is pulled into the clamp, the second clamping block can be rotated to allow the V-shaped block to rotate into the V-groove. Then, the connecting block is rotated to allow the locking bolt to rotate into the third slot. Rotating the locking bolt again pushes the second clamping block to continue rotating. Because the V-groove of the first clamping block and the V-shaped block of the second clamping block are in contact through symmetrical inclined surfaces, a geometrically self-centering structure is formed. When the locking bolt is pressed, the inclined surface contact generates a radial force, pushing the wire to automatically center and contact the bottom of the V-groove, achieving rapid positioning and fixation of the wire.

[0079] This embodiment achieves automatic alignment of the steel wire axis through the cooperation of the V-groove and V-block, and improves the accuracy of the grinder in grinding weld beads by adjusting the locking mechanism.

[0080] Exemplary, this embodiment provides one structure of the lifting mechanism, such as Figure 4 As shown, the lifting mechanism may include:

[0081] Fixing plate 62;

[0082] Lead screw 61, which is rotatably mounted on a fixed plate;

[0083] The slider 63 slides relative to the fixed plate and is threadedly engaged with the lead screw. The grinder is fixedly mounted on the slider.

[0084] The linear motion of the slider is driven by a lead screw, which improves the transmission response speed. The self-locking function of the lead screw reduces the probability of equipment failure. The lifting mechanism has a simple structure, few wear parts, and low replacement cost.

[0085] In this embodiment, the lead screw can be rotated manually or used in conjunction with a motor. Of course, besides using a lead screw drive structure to achieve linear motion of the slider, devices such as pneumatic cylinders, electric cylinders, and hydraulic cylinders can also be used to directly drive the slider linearly. However, compared to the solution provided in this embodiment, the structure is more complex.

[0086] In addition, in this embodiment, a guide structure is provided between the slider and the fixed plate, such as... Figure 3 As shown, a trapezoidal groove can be opened on the fixed plate, and a matching trapezoidal block can be machined on the back of the slider. Through the cooperation of the trapezoidal block and the trapezoidal groove, the motion guidance between the slider and the fixed plate can be realized, thereby restricting other movements other than the main motion direction.

[0087] Exemplary, this embodiment provides one structure of the rotating mechanism, such as Figure 8 As shown, the rotating mechanism may include:

[0088] In this embodiment, the mounting part 31 is fixedly mounted on the frame.

[0089] Handwheel 36, which is rotatably mounted on the mounting part;

[0090] Turntable 32 is rotated by turning a handwheel, and the fixing plate is fixedly installed on the turntable;

[0091] A cutout 34 for inserting steel wire is provided on one side of the mounting part and the turntable.

[0092] In this embodiment, the rotating mechanism may further include:

[0093] Gear set 33, which is connected to the handwheel;

[0094] Rack 37, which is fixed to the surface of the turntable around the edge of the turntable and meshes with the aforementioned gear set.

[0095] This embodiment uses a handwheel drive combined with a gear and rack transmission to rotate the turntable, which can quickly adjust the circumferential position of the grinder and reduce the time spent on repeated manual positioning.

[0096] In addition, the rotating mechanism may also include a guide wheel assembly 35, which is fixedly mounted on the mounting part and contacts the circumferential side of the turntable.

[0097] By limiting the radial runout of the turntable through the guide wheel assembly, the rotational accuracy of the turntable is improved. The rotation of the turntable is guided by the rolling of the guide wheel assembly, which can reduce the friction between the turntable and the mounting part.

[0098] In this embodiment, the handwheel can be replaced by a motor, rotary cylinder, or other device. The turntable is rotated by the power rotation, and the stroke of the power device is controlled by the controller, which can achieve precise indexing of the grinder.

[0099] In addition, the grinding mechanism may also include a collection trough 20, which is disposed entirely below the steel wire between the two sets of clamps.

[0100] This collection tank allows for the collection of welding slag that has been ground down, preventing it from falling onto the ground and becoming difficult to clean.

[0101] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
