[0032] In order to make the technical means, creative features, objectives and functional effects of the present invention easy to understand, the present invention will be further described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] [Example 1] In order to address the shortcomings of the existing technology, such as Figure 1As shown, the present invention provides a new type of hardware tool surface grinding equipment, including at least one rotating drive mechanism 1, and also including two groups of grinding components 4, the two groups of grinding components 4 rotate under the driving action of the rotating drive mechanism 1, and the two groups of grinding components 4 are commonly connected with an adaptive adjustment component 2 for adaptively adjusting the spacing between the two groups of grinding components 4; the rotating drive mechanism 1 is a combination of a motor or a motor + a reducer, and a rotor with an output end made thereon is fixedly connected to the grinding component 4; In this embodiment, Figure 1 The difference is that the two grinding assemblies 4 are each equipped with a rotation drive mechanism 1 .

[0034] It should be noted that, during the grinding process of the workpiece 001, the reciprocating mechanism 5 is placed above the bottom die 6 of comparable structural size, and transported to between the two groups of grinding assemblies 4, the rotating drive mechanism 1 is started, and the rotating drive mechanism 1 drives the grinding assembly 4 to rotate, and the workpiece 001 is transported and moved by being attached to the grinding assembly 4 along with the bottom die 6. During this period, the grinding assembly 4 can be adaptively adjusted based on the adaptive adjustment assembly 2 so that it is always attached to the outer wall of the workpiece 001, and the adjustment stroke of the grinding assembly 4 is subject to the bottom die 6.

[0035] Specifically, Figure 2 , 3 As shown, a novel self-adaptive adjustment component 2 for hardware tool surface grinding equipment, the self-adaptive adjustment component 2 includes two rocker arms 21 for controlling the positions of two grinding components 4, the two grinding components 4 are respectively attached to the corresponding rocker arms 21, and the two rocker arms 21 are rotatably connected to each other through shafts and bearings, a base frame 23 is arranged between the two rocker arms 21, and elastic members 22 are arranged between the two rocker arms 21 and the base frame 23; The base frame 23 can be any fixed frame in the grinding equipment, such as the housing of the motor or a fixed frame for fixing the motor. The two sets of rocker arms 21 and the elastic member 22 are symmetrically arranged based on the base frame 23. A base plate 211 for fixing the elastic member 22 is arranged on the rocker arm 21, and one end of the elastic member 22 away from the base plate 211 is fixedly connected to the base frame 23. The elastic member 22 is a spring. In order to respond to the rotation trajectory of the rocker arm 21, the elastic member 22 is as follows. Figure 3 The bending state shown.

[0036] It should be noted that the present invention is a new type of hardware tool surface grinding equipment. Through the provided adaptive adjustment component 2 and grinding component 4, during the grinding process of the workpiece 001, the workpiece 001 is conveyed between two transmission shafts 42, that is, located between two rollers 41 and moves in contact with the rollers 41; During the process, in order to ensure that the two rollers 41 always fit the outer wall of the workpiece 001 to be processed, the two groups of rollers 41 are respectively steered by the corresponding rocker arms 21 based on the transmission shafts 42 to which they are attached, and the two rocker arms 21 rotate relative to each other. It can be understood by those skilled in the art that, as an ideal operating state, for the specific structural dimensions of the workpiece 001 to be processed, in the initial state of the two elastic members 22, when the spacing between the two groups of rollers 41 is the smallest, it should be smaller than the minimum width or minimum length on the workpiece 001 to be processed. In this way, under the action of the two elastic members 22, the two groups of rollers 41 always fit the outer wall of the workpiece 001 to be processed for effective grinding.

[0037] In addition, in this embodiment, those skilled in the art can understand that, with respect to the surface curvature of the workpiece 001 to be processed, if the curvature is larger, it may be more appropriate to consider using a grinding assembly 4 with a smaller structural size.

[0038] It is worth mentioning that the two mutually rotating rocker arms 21 respectively drive the corresponding grinding components 4 to change their positions. During this period, under the action of the elastic member 22, the grinding components 4 are always attached to the outer surface of the workpiece 001 to be processed, so as to realize the simultaneous processing of the two sides of the surface of the workpiece 001 to be processed, effectively improve the processing efficiency, shorten the production cycle, and can adapt to the curved surface on the workpiece 001 to be processed. It is more suitable for grinding hardware tools with irregular surfaces such as wrenches, and can be applicable to workpieces 001 to be processed of various shapes and sizes, enhancing the versatility and applicability of the grinding equipment.

[0039] [Example 2] Based on the above embodiment 1, considering that the grinding assembly 4 is always attached to the surface of the workpiece 001 for grinding, in order to avoid excessive grinding of the workpiece 001, this embodiment is proposed: Specific, and Figure 2 , 3 As shown, a new type of grinding assembly 4 for hardware tool surface grinding equipment includes at least two rollers 41, and the two rollers 41 are commonly attached with a transmission shaft 42, wherein at least one roller 41 is a grinding roller, and at least one roller 41 other than the grinding roller is a guide roller or a polishing roller; When the roller 41 is a guide roller, the roller 41 is rotationally connected to the corresponding transmission shaft 42 . When the roller 41 is a grinding roller or a polishing roller, the roller 41 is fixedly connected to the corresponding transmission shaft 42 .

[0040] It should be noted that the present invention is a new type of hardware tool surface grinding equipment, through the grinding component 4, in this embodiment, as Figure 4In the structural state shown, the roller 41 located at the top is a grinding roller, and the roller 41 located at the bottom is a guide roller, which is used to move in contact with the bottom mold 6 to guide the grinding roller to prevent the roller 41 from causing excessive grinding to the workpiece 001.

[0041] As a preferred embodiment, the elastic member 22 can be removed and replaced by a mold having a structure size equivalent to that of the workpiece 001 to be processed. A guide groove is provided on the mold for cooperating with the roller member 41 as a guide roller to move. During the grinding process of the workpiece 001 to be processed, the mold can be placed as follows: Figure 4 As shown in the placement position of the bottom mold 6, the roller member 41 serving as a guide roller is extended into the interior of the hollow mold, and the movement of the roller member 41 is guided by the hollow mold so that the roller member 41 serving as a grinding roller will not cause excessive grinding to the workpiece 001.

[0042] [Example 3] Based on the above-mentioned embodiment 1 or 2, since there are two sets of grinding assemblies 4, the two sets of grinding assemblies 4 have their own driving sources. In order to achieve the degree of synchronization of grinding both sides of the workpiece 001, the rotation speed and other parameters of the two sets of driving sources need to be set synchronously. On the one hand, there are more structural erection costs, and on the other hand, the operating cost is also relatively high. For this reason, this embodiment is proposed: like Figure 1~2 As shown, a new type of hardware tool surface grinding equipment, in this embodiment, only one rotation drive mechanism 1 is used.

[0043] Specifically, Figure 3 As shown, a branch transmission mechanism 3 for a new type of hardware tool surface grinding equipment is provided between a rotation driving mechanism 1 and two sets of grinding assemblies 4. The branch transmission mechanism 3 includes a gear 1 31, and two gears 2 32 are meshed with the gear 1 31. With the gear 1 31 as a reference, the two gears 2 32 can revolve around the gear 1 31 and rotate on their own. The two gears 2 32 are respectively fixedly connected to the corresponding grinding assemblies 4. The branch transmission mechanism 3 also includes a base shaft 33 fixedly connected to the rotor on the rotation drive mechanism 1, and bearings 212 are provided between the base shaft 33 and the two rocker arms 21. The two rocker arms 21 are rotationally connected to the base shaft 33 through the corresponding bearings 212.

[0044] It should be noted that the present invention is a new type of hardware tool surface grinding equipment. Through the branch transmission mechanism 3, during the grinding process of the workpiece 001, the gear 1 31 is driven to rotate by the rotating drive mechanism 1, and the gear 1 31 drives the two gears 2 32 to rotate separately. Moreover, during the process of adaptively adjusting the spacing between the two groups of grinding components 4, the two gears 2 32 always maintain meshing transmission with the gear 1 31.

[0045] It is worth mentioning that by driving a single gear 1 31, the gear 1 31 drives the two gears 2 32 meshing with it to rotate, and the two gears 2 32 can rotate around the gear 1 31 while maintaining their own rotation. On the one hand, the two gears 2 32 with the same structural size can keep the grinding of the grinding assembly 4 synchronized. On the other hand, under the premise of effectively changing the position of the grinding assembly 4, the normal transmission of the grinding assembly 4 by the rotating drive mechanism 1 is guaranteed, further improving the use effect of the adaptive adjustment assembly 2, and the two grinding assemblies 4 can be driven by only a single rotating drive mechanism 1, effectively reducing the complexity and cost of the equipment.

[0046] [Example 4] Based on any of the above embodiments, considering that during the grinding process of the workpiece 001, a bottom mold 6 needs to be placed on the workpiece 001, in order to realize continuous processing of multiple batches of workpieces 001 and avoid using too many bottom molds 6, this embodiment is proposed: like Figure 4 As shown, a new type of hardware tool surface grinding equipment, the grinding equipment also includes a reciprocating mechanism 5, which is used to drive the entire equipment to reciprocate; the reciprocating mechanism 5 is a mechanism such as an electric slide, in which the reciprocating movement is mainly achieved through a screw assembly.

[0047] Specifically, Figure 5 As shown, a new type of grinding assembly 4 for hardware tool surface grinding equipment, when there are at least two rollers 41, the roller 41 serving as a grinding roller is located at the top, and the roller 41 serving as a guide roller or a polishing roller is located at the bottom.

[0048] It should be noted that the present invention is a new type of hardware tool surface grinding equipment. Through the provided grinding assembly 4, during the grinding process of the workpiece 001, the workpiece 001 is Figure 5 The material is fed into the grinding process in the direction of the one-way arrow shown in FIG. 1 . After the grinding process of the workpiece 001 is completed, the workpiece 001 is fed into the grinding process in the direction of the one-way arrow shown in FIG. Figure 5 The material is discharged in the direction of the double-headed arrow shown in FIG. During the process, the roller 41 located at the bottom is a guide roller, and the roller 41 located at the top is a fine-processing polishing roller. The grinding equipment as a whole reciprocates on the processing surface of the workpiece 001 through the external reciprocating mechanism 5. In at least one stroke of the reciprocating mechanism 5, the grinding process of a single workpiece 001 is realized, and the workpiece 001 to be processed after processing is pushed out from the side.

[0049] It is worth mentioning that, in this processing method, there are two workpieces 001 to be processed located between two sets of grinding assemblies 4 at the same time. No matter which workpiece 001 to be processed is used as the guide reference, excessive grinding or polishing of the other workpiece 001 to be processed can be avoided. Furthermore, because there are multiple workpieces 001 to be processed that are stacked, during the processing of the current workpiece 001 to be processed, the heat generated will be promptly transferred to the other workpiece 001 to be processed below it, which can effectively prevent the current workpiece 001 from overheating during the grinding process. The uniform temperature distribution can reduce the risk of workpiece deformation due to local overheating, help maintain the smoothness and flatness of the workpiece surface, and reduce surface defects caused by temperature changes, thereby ensuring processing accuracy and quality.

[0050] As a preferred embodiment, the roller 41 located at the bottom can be a rough-processing grinding roller, and the roller 41 located at the top can be a fine-processing polishing roller. The grinding equipment as a whole reciprocates on the processing surface of the workpiece 001 through an external reciprocating mechanism 5. In at least one stroke of the reciprocating mechanism 5, grinding and polishing of a single workpiece 001 are achieved, which is more in line with the needs of continuous production and processing.

[0051] Among them, technicians in this field can understand that in order to realize continuous processing of multiple batches of workpieces 001 to be processed, the workpieces 001 to be processed are conveyed by intermittent conveying equipment, such as a sprocket conveyor belt controlled by a cam divider. The cam divider allows a fixed loading cycle for the workpieces 001 to be processed, and the sprocket conveyor belt constitutes a closed-loop feeding space, which reduces the overall space occupied by the equipment to a certain extent. This can be set up with reference to the existing technology and will not be elaborated on here.

[0052] [Example 5] Based on the above-mentioned embodiments 1, 2 or 3, considering that the height of the grinding surface of the workpiece 001 to be processed may not be consistent, in order to adapt to the grinding of the workpiece 001 to be processed with multiple structural sizes, this embodiment is proposed: Further, such as Figures 6 and 7 As shown, a new type of grinding assembly 4 for hardware tool surface grinding equipment, a limited retaining edge 411 is arranged at the outer edge of one end of a roller 41, a key shaft 412 is attached to the roller 41, a groove 413 is formed on the key shaft 412, a spring 414 is fixedly connected inside the groove 413; a key groove 421 is formed on the transmission shaft 42, the key groove 421 is meshed with the key shaft 412, and the other end of the spring 414 is fixedly connected to the transmission shaft 42; The limit rib 411 is fixedly connected to the roller 41. The limit rib 411 is made of a hard non-rubber material. While ensuring the normal processing efficiency of the roller 41, it avoids unnecessary scratches on the workpiece 001 during the processing; the key shaft 412 is fixedly connected to one end of the roller 41, and the key shaft 412 is a spline.

[0053] It should be noted that the present invention is a new type of hardware tool surface grinding equipment. By setting the grinding assembly 4, taking the grinding process of the side of the workpiece 001 as an example, the outer edge of one end of the roller 41 is abutted against the workpiece 001 or the upper end or lower end of the bottom mold 6 through the limiting retaining edge 411, so that the roller 41 can make adaptive adjustments based on the limiting retaining edge 411 according to the processing surface of the workpiece 001; When the roller 41 is adjusted based on the limit rib 411 to follow the height of the workpiece 001, the roller 41 is always engaged with the transmission shaft 42 through the key shaft 412 and based on the key groove 421 while being axially movable, and the spring 414 provides a pulling force to enable the limit rib 411 to always fit the workpiece 001.

[0054] It is worth mentioning that, under the premise of ensuring that the roller 41 does not separate from the normal transmission of the transmission shaft 42, the key shaft 412 and the key groove 421 constitute the axial movement between the roller 41 and the transmission shaft 42, so that the roller 41 can adapt to the different surface heights of the workpiece 001 to be processed. On the basis of the adaptive adjustment component 2, the flexibility and adaptability of the grinding equipment are further improved.

[0055] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only for illustrating the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed for protection.
