Technical Field
[0001] The utility model relates to the technical field of screwdriver production, in particular to a fine grinding device for screwdriver production. Background Art
[0002] A screwdriver is a common tool used to turn screws to put them in place. It usually has a thin wedge-shaped head that can be inserted into the slot or notch of the screw head. According to different head shapes, it can be divided into flat head, cross head, Pozidriv head, star head (computer), square head, hexagonal head, Y-shaped head, etc. As a commonly used maintenance tool, it has a large market demand. In its mass production process, the turning, milling and grinding of the screwdriver blade is an important process, and there is a high demand for its accuracy, which directly affects the use effect and service life.
[0003] At present, in the production process of screwdrivers, a turning and milling machine is often used to grind and shape the screwdriver bits in one piece, which has high work efficiency. However, the screwdriver bits after forming often have burrs and need to be further polished. The commonly used grinding equipment usually uses a vibration machine to vibrate the screwdrivers in batches, so that they rub against each other to remove the burrs. Although batch grinding can be performed, the grinding effect is not very ideal and it takes a long time to grind. In addition, most factories also use grinding equipment to further fine-grind the screwdriver bits after forming. However, due to the large number of screwdriver bit models and the fact that some combination screwdrivers usually have double-headed structures, the existing grinding equipment has certain limitations when used, that is, different types of screwdriver bits have different fine-grinding requirements. The grinding equipment in the prior art usually needs to clamp and fix the screwdriver bits to be ground before grinding, and the clamping position is often not able to be ground, and the double-headed screwdriver bits need to be flipped for grinding, which increases the frequency of operation and further prolongs the working time, reducing the grinding efficiency.
[0004] Based on this, the utility model proposes a screwdriver production fine grinding device to solve the above problems. Utility Model Content

[0007] Furthermore: the fifth driving component is driven by a screw motor, and its screw shaft adopts a forward and reverse bidirectional screw. The two sets of clamping parts are placed at both ends of the fixed seat and are adapted to slide on its forward and reverse bidirectional screw.
[0008] Further: the fixing seat is slidably arranged at the bottom of the fixing frame, and is driven to slide on the fixing frame by a sixth driving component arranged below the fixing seat.
[0009] Furthermore: the clamping member and the fourth driving component provided on the fixing seat are both fixed by a detachable structure.
[0010] Furthermore: a seventh driving component and an eighth driving component are also arranged between the second driving component on the fixed frame and the third driving component of the grinding assembly. The seventh driving component and the eighth driving component are fixed at the adaptation position through the base body and respectively drive the grinding assembly to rotate in different directions.
[0011] Further: the grinding head is connected to the third driving component via a detachable structure.
[0012] Compared with the prior art, the utility model has the following advantages and effects:
[0013] 1. The utility model is a fine grinding device for screwdriver production, which can not only be adaptively adjusted for screwdriver bits of different models to meet different fine grinding requirements, but also achieve a higher precision and grinding effect in the grinding process by precisely controlling the above-mentioned multiple driving components.

DETAILED DESCRIPTION
[0020] The present invention will be further described in detail below with reference to the accompanying drawings and through examples. The following examples are provided to explain the present invention, but the present invention is not limited to the following examples.
[0021] See also Figure 1-4The present embodiment relates to a fine grinding device for screwdriver production, including a fixed frame 1, a grinding assembly 2 is slidably provided on the top of the fixed frame 1 and is driven to slide left and right by a first driving component 101 provided on the top of the fixed frame 1, a clamping assembly 3 is provided at the bottom, a second driving component 102 is provided at the connection position between the grinding assembly 2 and the fixed frame 1 to drive the grinding assembly 2 to slide up and down, including a grinding head 21, the grinding head 21 is connected to a third driving component 103 to drive rotation, the clamping assembly 3 includes a fixed seat 31 and a clamping member 32, the clamping member 32 is provided with two groups and both are connected to a fourth driving component 104 to drive rotation, and a fifth driving component 105 is provided on the fixed seat 31 to drive the two groups of clamping members 32 to slide relative to each other.
[0022] Specifically in this embodiment, the specific structure of the clamping assembly 3 can be seen in Figure 1 , 2 As shown in Figure 4, one end of the screwdriver bit is first clamped and fixed by a clamping member 32 on one side. Taking the figure as an example, the clamping member 32 can be clamped and fixed by a four-jaw chuck structure. After the screwdriver bit is fixed, the clamping member 32 and the screwdriver bit can be driven to rotate by the fourth driving member 104. During the rotation, the grinding head 21 is driven by the third driving member 103 to rotate. The third driving member 103 and the fourth driving member 104 both use adapted driving motors to drive the grinding head 21 and the clamping member 32 to rotate respectively. At the same time, the grinding assembly 2 is driven by the first driving member 101 and the second driving member 102 to adjust the position in different directions on its fixed frame 1. Specifically, the first driving member 101 and the second driving member 102 are driven by a screw motor. The specific structure can be seen in FIG. Figure 1-3As shown in the figure, the grinding assembly 2 is driven by the first driving component 101 and the second driving component 102 to slide along the screw shaft 110 of the screw motor in the adapting direction, so as to realize the movement and adjustment of the grinding assembly 2 in different directions, so that it moves to the lower clamping member 32 to contact the rotating screwdriver bit, and the grinding head 21 and the screwdriver bit are respectively driven by the third driving component 103 and the fourth driving component 104 to rotate, so as to grind and remove burrs from the surface of the screwdriver bit. During the grinding process, the grinding head 21 is driven by the first driving component 101 and the second driving component 102 to move along the grinding direction of the screwdriver bit to realize the grinding process of the screwdriver surface, and the signal lines of the first driving component 101 and the second driving component 102 are connected with a controller, and under the control of the controller, the precise position adjustment of the grinding head 21 can be realized, so as to adjust the screwdriver bit. The fourth driving component 104 stops working to stop the rotation of the four-jaw chuck and the screwdriver bit. Subsequently, the clamping member 32 drives the two groups of clamping members 32 to slide in relative directions on the fixed seat 31 under the drive of the fifth driving component 105. The fifth driving component 105 drives the two groups of clamping members 32 to slide in relative positions on the fixed seat 31 by driving two groups of screw motors, so that the clamping member 32 on the side that does not clamp the screwdriver bit moves and contacts the clamping member 32 that clamps the screwdriver bit. The screwdriver bit is clamped and fixed by the clamping member 32 on the unclamped side and separated from the clamping member 32 on the other side through the opening and closing of the four-jaw chuck. The grinding assembly 2 continues to work to grind the ungrinded position of the screwdriver bit, thereby realizing all-round grinding of the screwdriver bit. This type of screwdriver fine-grinding device can not only be adaptively adjusted for screwdriver bits of different models to meet different fine-grinding requirements, but also through precise control of the above-mentioned multiple driving components, the grinding process has higher precision and grinding effect. At the same time, this type of fine-grinding device can automatically adjust the clamping position under the action of its clamping component 3, thereby reducing the frequency of manual operation, further shortening the grinding time and improving the grinding efficiency. For screwdriver bits with a double-head structure, double-head position grinding can be achieved to meet different usage conditions and usage requirements.
[0023] The fifth driving component 105 is driven by a screw motor, and its screw shaft 110 adopts a forward and reverse bidirectional screw. The two groups of clamping members 32 are placed at both ends of the fixed seat 31 and slide on the forward and reverse bidirectional screw. The screw shaft 110 adopting the forward and reverse bidirectional screw can be driven to rotate by a group of screw motors to realize the two groups of clamping members 32 to be adjusted in both directions of approaching and moving away synchronously, so that compared with the driving method of two groups of screw motors being controlled separately, its position control is more precise, and at the same time, it can further reduce energy loss, and the overall structure is simple, reducing production and use costs.
[0024] The fixing seat 31 is slidably disposed at the bottom of the fixing frame 1, and is driven to slide on the fixing frame 1 by the sixth driving component 106 disposed below the fixing seat 31, as shown in FIG. Figure 5 As shown, the sixth driving component 106 is driven by a screw motor, and the fixed seat 31 can slide on its fixed frame 1 under the drive of its sixth driving component 106 to achieve different position adjustments of the fixed seat 31, and can be adaptively adjusted to screwdriver bits of different lengths and sizes to cooperate with the grinding component 2 to adjust to the best grinding position, meet different usage requirements, and increase the flexibility and adaptability of this fine grinding device.
[0025] The clamping member 32 and the fourth driving member 104 provided on the fixed seat 31 are fixed by a detachable structure. The clamping member 32 and the fourth driving member 104 can be installed and disassembled according to different usage requirements. It can be seen that the required grinding workpiece is fixed on the screw shaft 110 of the screw motor of the fifth driving member 105, and is adaptively slid on the fixed seat 31 under the driving action of the fifth driving member 105, so as to cooperate with the grinding component 2 for grinding, meet different grinding requirements, be suitable for different workpieces to be ground, and be more flexible in adjustment.
[0026] See also Figure 6A seventh driving component 107 and an eighth driving component 108 are also provided between the second driving component 102 on the fixed frame 1 and the third driving component 103 of the grinding assembly 2. The seventh driving component 107 and the eighth driving component 108 are fixed at the adaptation position through the seat body and respectively drive the grinding assembly 2 to rotate in different directions. The seventh driving component 107 and the eighth driving component 108 are driven by synchronous belts. The seventh driving component 107 can drive the third driving component 103 and the grinding head 21 to swing left and right on its adaptation seat body. The eighth driving component 108 can drive the seventh driving component 107, the third driving component 103 and the grinding head 21 to adapt and rotate along the rotating shaft 1071 provided on the seat body of the seventh driving component 107. Driven by the seventh driving component 107 and the eighth driving component 108, the grinding head 21 of the grinding assembly 2 can be flexibly adjusted at different angles and directions, so that it can be adaptively adjusted and ground for mounting structures such as grooves or convexities on the screwdriver bit. The grinding assembly 2 of this fine grinding device can realize multi-axis rotation under the drive of its multiple sets of driving components, and has complex and diverse motion paths and trajectories to meet different grinding needs.
[0027] The grinding head 21 is connected to the third driving component 103 through a detachable structure. The grinding head 21 can be adapted and installed through the adaption installation groove 1031 provided on the third driving component 103. While facilitating installation and disassembly, the grinding head 21 with different sizes or precisions can be replaced according to different usage requirements. The adaption grinding head 21 can be replaced according to the different material characteristics of the screwdriver bit to be polished, thereby further improving the grinding effect and grinding accuracy, reducing the probability of damage to the workpiece, and saving the use cost.
