Description

Technical Field

[0001] This utility model relates to the field of net cart production technology, and in particular to a grinding device for producing side panels of net carts. Background Technology

[0002] During the manufacturing process of the mesh cart, after the side panel components are welded between the frame and the mesh panel, the weld beads need to be ground to ensure product quality and safe use.

[0003] Currently, the grinding of products like the side panels of mesh carts largely relies on operators using handheld angle grinders. This manual method has several drawbacks: First, it involves high labor intensity for workers, leading to fatigue and safety hazards over long periods. Second, the grinding quality is highly dependent on the worker's experience and skill, making it difficult to guarantee product consistency and resulting in significant fluctuations in yield. Third, manual grinding is inefficient, becoming a bottleneck process on the production line and hindering the improvement of overall production efficiency.

[0004] Therefore, there is an urgent need in this field for a dedicated device designed for the grinding process of the side panels of mesh carts, in order to effectively improve production efficiency and reduce the labor intensity of workers while ensuring grinding quality and operational safety. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, this utility model discloses a grinding device for the production of side panels of a net cart.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A grinding device for producing side panels of a mesh cart includes:

[0008] frame;

[0009] A transverse slide rail beam is mounted on the frame in a height-adjustable manner;

[0010] A sliding base is movably mounted on the transverse slide rail beam;

[0011] A drive mechanism, mounted on the transverse slide rail beam, is used to drive the sliding base to move along the transverse slide rail beam;

[0012] An angle grinder is fixedly installed at the bottom of the sliding base;

[0013] A clamping mechanism, disposed on the frame, is used to position the workpiece on the grinding path of the angle grinder.

[0014] Furthermore, the two ends of the transverse slide rail beam are slidably connected to the slide rail set on the frame by magnetic sliders, and the magnetic sliders can be attracted and fixed at the two ends of the slide rail.

[0015] Furthermore, the driving mechanism is a lead screw motor assembly, and the lead screw of the lead screw motor assembly is in transmission cooperation with the sliding base.

[0016] Furthermore, the lower end of the sliding base is provided with an n-shaped frame and a U-shaped frame, the head end of the angle grinder is detachably connected to the n-shaped frame by bolts, and the body of the angle grinder is fixed by the U-shaped frame.

[0017] Furthermore, the clamping mechanism includes:

[0018] The L-shaped mounting bracket is fixed to the frame;

[0019] The flipping frame is hinged to the outer end of the horizontal section of the L-shaped fixed frame via a spring hinge, so that the flipping frame has a clamping tendency to flip toward the vertical section of the L-shaped fixed frame;

[0020] A fixed pressure bar is installed at the upper end of the flipping frame to press the top of the workpiece;

[0021] The movable pressure rod has connecting rods at both ends, and the connecting rods are hinged to the middle of the flipping frame via spring hinges, so that the connecting rods and the movable pressure rod have a tendency to flip toward the vertical section of the L-shaped fixed frame to press the bottom of the workpiece.

[0022] Furthermore, the horizontal section of the L-shaped fixing frame constitutes a positioning part for the workpiece in the vertical direction.

[0023] Furthermore, the clamping mechanism also includes a transverse baffle disposed on one side of the L-shaped fixing frame for transverse positioning of the workpiece.

[0024] Furthermore, the frame is equipped with a lifting device for driving the horizontal slide rail beam to rise and fall.

[0025] Compared with the prior art, the beneficial effects of this utility model are:

[0026] 1. The automatic drive mechanism automatically drives the sliding base and angle grinder to perform lateral feed motion, realizing the automation of the grinding process, significantly improving grinding efficiency, and overcoming the production bottleneck of manual operation;

[0027] 2. The clamping mechanism is designed with spring hinges to enable the flipping frame, fixed pressure bar, and movable pressure bar to automatically clamp, achieving rapid workpiece clamping and release. Simultaneously, the coordinated action of the horizontal and vertical sections of the L-shaped fixed frame and the transverse baffle provides three-dimensional positioning of the workpiece (up / down, forward / backward, and laterally), ensuring its stability during grinding and effectively preventing uneven grinding or defects caused by workpiece displacement, thus guaranteeing the consistency and stability of product grinding quality.

[0028] 3. The horizontal slide beam is height-adjustable via magnetic sliders or lifting devices, allowing for quick adjustment of the angle grinder's working height according to the workpiece's placement, enhancing the device's applicability and flexibility. The angle grinder is installed using a combination of N-type and U-type frames, ensuring secure mounting and disassembly for easy maintenance or replacement.

[0029] 4. The overall structure is relatively simple. It mainly uses a conventional angle grinder as the power head and combines it with a mechanical structure to transform manual grinding into automated operation. The manufacturing cost is much lower than that of general CNC grinding equipment, and it greatly reduces the labor intensity of operators. It is especially suitable for small and medium-sized enterprises to carry out technological upgrades and transformations. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0037] It should be noted that in the description of this utility model, if the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. are used to indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, they are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0038] Please refer to the instruction manual appendix. Figure 1-5 This utility model provides a technical solution:

[0039] Example 1: A grinding device for producing side panels of a mesh cart, designed to solve the problems of low grinding efficiency, high labor intensity, and unstable grinding quality in the prior art; including a frame 1, a transverse slide beam 2, a sliding base 3, a drive mechanism, an angle grinder 5, and a clamping mechanism 6.

[0040] The frame 1 serves as the supporting structure for the entire device, and in this embodiment, it is an H-shaped frame welded from structural steel. A slide rail 11 extending vertically is provided on the inner top side of the frame 1.

[0041] The transverse slide beam 2 is slidably connected to the slide rail 11 on the frame 1 via magnetic sliders 21 at both ends. The overall height of the transverse slide beam 2 can be adjusted by sliding the magnetic sliders 21 on the slide rail 11. When adjusted to the upper or lower limit height, the magnetic attraction of the magnetic sliders 21 firmly attaches them to the ends of the slide rail 11, thus reliably fixing the transverse slide beam 2 at that height and ensuring the stability of the grinding process. Specifically, the upper limit height of the transverse slide beam 2 corresponds to grinding operations where the workpiece is placed vertically, such as... Figure 4 As shown; the lower limit height of the transverse slide beam 2 corresponds to the grinding operation when the workpiece is placed transversely, such as... Figure 1 As shown.

[0042] The drive mechanism is mounted on the transverse slide beam 2 and is used to drive the sliding base 3 to move laterally. In this embodiment, the drive mechanism is preferably a lead screw motor assembly 4, which includes a servo motor, a lead screw connected to the motor output shaft, and a bearing housing supporting the lead screw. The sliding base 3 is driven by the lead screw through its internal nut structure. When the lead screw motor assembly 4 is working, the rotation of the lead screw can drive the sliding base 3 to move precisely and smoothly along the length of the transverse slide beam 2.

[0043] The lower end of the sliding base 3 is fixed with an assembly for mounting the angle grinder 5. Specifically, an n-shaped bracket 31 is provided on the front side of the lower end face of the sliding base 3, and the head end of the angle grinder 5 is detachably connected to the n-shaped bracket 31 by bolts 32. The specific installation method is as follows: first, remove the original side handles on both sides of the head end of the angle grinder 5, at which point threaded holes for mounting the side handles will be exposed on both sides of the head end of the angle grinder 5; then, use bolts 32 to pass through the mounting holes of the n-shaped bracket 31 and screw them into the threaded holes of the head end of the angle grinder 5 for tightening. At the same time, a U-shaped bracket 33 is also provided at the bottom of the lower end face of the sliding base 3. The U-shaped bracket 33 is used to support and hold the body of the angle grinder 5. Through the combined action of the n-shaped bracket 31 and the U-shaped bracket 33, the angle grinder 5 is securely mounted under the sliding base 3.

[0044] The clamping mechanism 6 is mounted on the frame 1 and located below the grinding path of the angle grinder 5, and is used to reliably position and clamp the workpiece during the grinding process. The clamping mechanism 6 includes an L-shaped fixed frame 61, a flipping frame 62, a fixed pressure bar 63, and a movable pressure bar 64.

[0045] The vertical section of the L-shaped fixing bracket 61 is fixedly installed on the front side of the web of the frame 1. Its horizontal section extends forward, and the upper surface of the horizontal section forms a positioning reference surface for the workpiece in the vertical direction.

[0046] The flipping frame 62 is hinged to the outer end of the horizontal section of the L-shaped fixing frame 61 via a spring hinge. Under the torque provided by the spring hinge, the flipping frame 62 has a clamping tendency to continuously flip toward the vertical section of the L-shaped fixing frame 61.

[0047] A fixing rod 63 is fixedly installed at the upper end of the tilting frame 62. When the tilting frame 62 is closed, the fixing rod 63 presses against the top of the workpiece.

[0048] On each side of the middle section of the flipping frame 62, a connecting rod 65 is hinged via a spring hinge. The free ends of the two connecting rods 65 are connected to the movable pressure rod 64. Under the action of the spring hinges, the connecting rods 65 and the movable pressure rod 64 as a whole tend to flip towards the vertical section of the L-shaped fixed frame 61, thereby pressing against the bottom of the workpiece.

[0049] When the workpiece is placed, its bottom surface rests on the horizontal section of the L-shaped fixing frame 61 for vertical positioning; one side of the workpiece is close to the inner side of the vertical section of the L-shaped fixing frame 61. When the flipping frame 62 is closed manually or automatically, the movable pressure rod 64 presses the bottom of the workpiece and the fixed pressure rod 63 presses the top of the workpiece under the action of spring force, forcing the entire side of the workpiece to be ground to be in close contact with the inner wall of the vertical section of the L-shaped fixing frame 61, thereby achieving precise positioning of the workpiece in the front-back direction.

[0050] To perform lateral positioning of the workpiece, the clamping mechanism 6 also includes a lateral baffle 66 disposed on the left or right side of the L-shaped fixing frame 61. When the workpiece is placed, its side is pressed against the lateral baffle 66 to complete the lateral positioning.

[0051] It should be noted that the drive mechanism is not limited to the lead screw motor group 4. In other alternatives, it can also be a belt drive mechanism, a gear and rack mechanism, or a linear motor, etc., that can achieve linear drive.

[0052] Similarly, the specific form of the clamping mechanism 6 is not limited to the structure described above. For example, the flipping frame 62 can be opened and closed by a cylinder or an electromagnet, rather than relying entirely on a spring hinge; rubber pads or rollers can be added to the fixed pressure rod 63 and the movable pressure rod 64 to ensure clamping force while avoiding scratching the surface of the workpiece.

[0053] Example 2: A grinding device for producing side panels of a mesh cart, differing from Example 1 in that: in this example, the frame 1 is equipped with a lifting device for driving the horizontal slide beam 2 to rise and fall. The lifting device can be an electric push rod, a pneumatic cylinder, or a hydraulic cylinder.

[0054] Taking the electric push rod as an example, its cylinder is fixed to the frame 1, and the extended end of its push rod is connected to the end of the transverse slide beam 2. By controlling the extension and retraction of the electric push rod, the lifting and lowering of the transverse slide beam 2 can be automatically controlled and stabilized at the preset upper or lower limit height, thus eliminating the need for manual lifting and lowering of the transverse slide beam 2 and achieving a higher degree of automation.

[0055] The working principle is as follows:

[0056] Raise the transverse slide beam 2 to its upper limit position to allow space for operation. Place the side plate of the mesh cart to be ground on the L-shaped fixed frame 61, with its bottom surface in contact with the horizontal section and its side edge close to the transverse baffle 66, with the surface to be ground facing upwards. Close the tilting frame 62. Under the automatic action of the spring hinge, the fixed pressure rod 63 and the movable pressure rod 64 press the top and bottom of the workpiece respectively, so that the workpiece is firmly positioned on the L-shaped fixed frame 61. Adjust the height of the transverse slide beam 2 according to the placement of the workpiece, start the angle grinder 5 and the lead screw motor 4. The angle grinder 5 rotates at high speed, and at the same time, the sliding base 3, driven by the lead screw motor 4, drives the angle grinder 5 to move smoothly laterally to grind the surface of the workpiece. After grinding is completed, stop the equipment, open the tilting frame 62, and take out the ground workpiece.

It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that this utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the above embodiments should be regarded as exemplary and non-limiting in all respects.

Therefore, it is intended to include all changes that fall within the meaning and scope of the equivalents of the claims within this utility model.
