Description

Technical Field

[0001] This utility model relates to a positioning mechanism for tungsten carbide grinding that is easy to adjust, and belongs to the field of tungsten carbide grinding technology. Background Technology

[0002] Tungsten carbide, a hard alloy composed of tungsten and carbon, possesses extremely high hardness, wear resistance, and bending strength, and is commonly used in the manufacture of cutting tools, molds, and wear-resistant parts. In the finishing process of tungsten carbide products, grinding is a crucial step, aiming to achieve extremely high dimensional accuracy and surface finish. Stable and precise positioning of the tungsten carbide workpiece is a prerequisite for ensuring grinding quality. Therefore, a positioning mechanism specifically designed for tungsten carbide grinding has become an indispensable piece of equipment in this machining field.

[0003] In existing technologies, positioning fixtures used for tungsten carbide grinding generally suffer from inconvenient adjustment and poor versatility. Traditional fixed fixtures are difficult to adapt to workpieces of different sizes and specifications, requiring tedious repositioning and calibration each time a workpiece is changed, severely impacting processing efficiency. Some fixtures with adjustment functions often have complex adjustment mechanisms, making operation less intuitive and convenient, or relying on manual experience for fine-tuning, resulting in inconsistent positioning accuracy. Furthermore, repeated adjustments can easily lead to gaps or loosening, causing a decrease in positioning stability. These problems directly affect the consistency and pass rate of tungsten carbide workpiece grinding, making it difficult to meet the dual demands of efficiency and precision in modern precision machining.

[0004] Therefore, a positioning mechanism for grinding tungsten carbide that is easy to adjust is proposed. Utility Model Content

[0005] In view of this, the present invention provides a positioning mechanism for grinding tungsten carbide that is easy to adjust, so as to solve or alleviate the technical problems existing in the prior art, and at least provide a beneficial option.

[0006] The technical solution of this utility model is achieved as follows: a positioning mechanism for grinding tungsten carbide that is easy to adjust, including a fixed base, and an adjustment component is provided on the right side of the fixed base;

[0007] The adjustment assembly includes an L-shaped plate, which is located on the right side of the fixed base. A screw is movably connected to the bottom of the inner side of the L-shaped plate via a bearing. A threaded sleeve is threaded onto the surface of the screw. A stop rod is movably connected to both the front and back sides of the threaded sleeve. An adjustment plate is movably connected to the end of the stop rod away from the threaded sleeve.

[0008] More preferably, the right sides of both the front and rear sides of the L-shaped plate are fixedly connected to a fixing frame, and the right side of the adjusting plate is movably connected to the inside of the fixing frame.

[0009] More preferably, a servo motor for driving the screw rotation is fixedly connected to the left side of the L-shaped plate, and the output end of the servo motor is fixedly connected to the left end of the screw.

[0010] More preferably, the front and back sides of the inner bottom of the L-shaped plate are provided with transverse sliding grooves, and the bottom of the front and back sides of the threaded sleeve are fixedly connected with support sliding rods, with the end of the support sliding rod away from the threaded sleeve slidably connected to the inner cavity of the transverse sliding groove.

[0011] More preferably, a positioning frame is fixedly connected to the top of the adjusting plate, a threaded rod is threadedly connected to the top of the positioning frame, a pressure plate is movably connected to the bottom of the threaded rod, and an anti-slip pad is adhered to the bottom of the pressure plate.

[0012] More preferably, a longitudinal slider is fixedly connected to the left side of the threaded rod, and a longitudinal groove is provided on the left side of the inner side of the positioning frame, and the left side of the longitudinal slider is slidably connected to the inner cavity of the longitudinal groove.

[0013] More preferably, a cylinder is fixedly connected to the left side of the fixed base, the output end of the cylinder extends through to the right side of the fixed base, and the output end of the cylinder is fixedly connected to the left side of the L-shaped plate.

[0014] The present invention has the following advantages due to the adoption of the above technical solution:

[0015] I. This utility model uses a cylinder to drive the overall movement of the adjustment assembly for coarse positioning, and then uses a servo motor to drive the screw to rotate, causing the screw sleeve to move axially. This, in turn, pushes the adjustment plate to deflect around its hinge point with the fixed frame through two abutments, thereby achieving fine adjustment of the angle of the adjustment plate and its upper components. Finally, by turning the threaded rod, the pressure plate and anti-slip pad are moved down to press the workpiece. This design integrates coarse and fine adjustment functions, and the adjustment process is continuous and stable, significantly improving the accuracy and efficiency of workpiece positioning. It is especially suitable for grinding scenarios that require precise angle control.

[0016] Second, this utility model ensures the straightness and stability of the threaded sleeve's movement through the sliding engagement of the support slide rod and the transverse slide groove. The sliding engagement of the longitudinal slider and the longitudinal slide groove prevents the threaded rod from rotating during rotation, ensuring that the pressure plate only performs a vertical downward clamping movement. These auxiliary structures effectively improve the rigidity and reliability of the entire mechanism during adjustment and clamping, avoiding positioning errors caused by component wobbling or deflection, resulting in more stable workpiece clamping and further guaranteeing the quality of the grinding process.

As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0025] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0026] Example 1

[0027] like Figure 1-4As shown, this utility model embodiment provides a positioning mechanism for tungsten carbide grinding that is easy to adjust, including a fixed base 1, and an adjustment component 3 is provided on the right side of the fixed base 1; the adjustment component 3 includes an L-shaped plate 301, which is located on the right side of the fixed base 1. A screw 305 is movably connected to the bottom of the inner side of the L-shaped plate 301 through a bearing. A screw sleeve 306 is threadedly connected to the surface of the screw 305. A stop rod 307 is movably connected to both the front and back sides of the screw sleeve 306. An adjustment plate 308 is movably connected to the end of the stop rod 307 away from the screw sleeve 306.

[0028] Coarse positioning is achieved by driving the adjustment assembly 3 to move as a whole using cylinder 2, and then rotating the screw 305 using servo motor 302, causing the screw sleeve 306 to move axially. This, in turn, pushes the adjustment plate 308 around its hinge point with the fixed frame 304 via two abutment rods 307, thus achieving fine adjustment of the angle of the adjustment plate 308 and its upper components. Finally, the pressure plate 6 and anti-slip pad 7 are moved down and pressed against the workpiece by turning the threaded rod 5. This design integrates coarse and fine adjustment functions, and the adjustment process is continuous and stable, significantly improving the accuracy and efficiency of workpiece positioning. It is especially suitable for grinding scenarios that require precise angle control.

[0029] Example 2

[0030] In one embodiment, a fixing bracket 304 is fixedly connected to the right side of both the front and rear sides of the L-shaped plate 301. The right side of the adjusting plate 308 is movably connected to the inner side of the fixing bracket 304. A servo motor 302 for driving the screw 305 to rotate is fixedly connected to the left side of the L-shaped plate 301. The output end of the servo motor 302 is fixedly connected to the left end of the screw 305. A transverse sliding groove 303 is provided on the front and back sides of the bottom inner side of the L-shaped plate 301. A support slide rod 309 is fixedly connected to the bottom of the front and back sides of the screw sleeve 306. The end of the support slide rod 309 away from the screw sleeve 306 is slidably connected to... In the inner cavity of the transverse slide groove 303, the top of the adjusting plate 308 is fixedly connected to the positioning frame 4, the top of the positioning frame 4 is threadedly connected to the threaded rod 5, the bottom of the threaded rod 5 is movably connected to the pressure plate 6, the bottom of the pressure plate 6 is bonded with the anti-slip pad 7, the left side of the threaded rod 5 is fixedly connected to the longitudinal slider 8, the left side of the inner side of the positioning frame 4 is provided with a longitudinal slide groove 9, the left side of the longitudinal slider 8 is slidably connected to the inner cavity of the longitudinal slide groove 9, the left side of the fixed seat 1 is fixedly connected to the cylinder 2, the output end of the cylinder 2 extends through to the right side of the fixed seat 1, and the output end of the cylinder 2 is fixedly connected to the left side of the L-shaped plate 301.

[0031] The sliding engagement between the support slide bar 309 and the transverse slide groove 303 ensures the straightness and stability of the threaded sleeve 306 during movement. The sliding engagement between the longitudinal slider 8 and the longitudinal slide groove 9 prevents the threaded rod 5 from rotating during rotation, ensuring that the pressure plate 6 only performs a vertically downward clamping motion. These auxiliary structures effectively improve the rigidity and reliability of the entire mechanism during adjustment and clamping, avoiding positioning errors caused by component wobbling or deflection, resulting in more stable workpiece clamping and further guaranteeing the quality of the grinding process.

[0032] In operation, this invention works as follows: First, cylinder 2 is activated, and its output pushes the adjusting assembly 3 to move to the right, bringing it closer to the tungsten carbide workpiece to be ground, thus completing the initial coarse positioning. Then, servo motor 302 is activated, driving screw 305 to rotate. Since the screw sleeve 306 is threadedly connected to screw 305, and its rotation is restricted by a sliding connection between the screw sleeve 306 and the transverse groove 303 on the L-shaped plate 301 via a support slide rod 309 at its bottom, the rotation of screw 305 is converted into left-right movement of the screw sleeve 306 along its axis. When the screw sleeve 306 moves to the right, it pushes two abutment rods 307 to move. The two ends of the abutment rods 307 are movably connected to the screw sleeve 306 and the adjusting plate 308, respectively, while the right side of the adjusting plate 308 is movably connected to the fixed frame 304. Therefore, the movement of the threaded sleeve 306 is converted into a pushing or pulling force on the adjusting plate 308 through the abutment rod 307, forcing the adjusting plate 308 to tilt with its connection point with the fixed frame 304 as the fulcrum, thereby changing the tilt angle of the adjusting plate 308 and realizing the fine adjustment of the angle of the workpiece bearing surface. After the angle is properly adjusted, the workpiece is placed on the top of the adjusting plate 308, and then the threaded rod 5 is screwed. Since the threaded rod 5 is threadedly connected to the positioning frame 4, and the longitudinal slider 8 on the threaded rod 5 is slidably connected to the longitudinal slide groove 9 on the positioning frame 4, the circumferential rotation of the threaded rod 5 is restricted. Therefore, screwing the threaded rod 5 will make it move downward. The bottom of the threaded rod 5 pushes the pressure plate 6 and the anti-slip pad 7 to move downward until the anti-slip pad 7 tightly presses the workpiece, completing the final clamping and fixing of the workpiece, and the grinding operation can then be carried out.

[0033] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
