[0026] Below, embodiments of the present invention are described in detail with reference to the accompanying drawings. To make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0027] Therefore, the following detailed description of the embodiments of the present invention provided in conjunction with the accompanying drawings is not intended to limit the scope of the present invention for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of the present invention.

[0028] The workpiece positioning mechanism for a grinder in this embodiment is arranged on one side of a column of a grinder, especially a double-head compound grinder, and can move back and forth along the Z-axis direction with the column to position rectangular workpieces.

[0029] like Figure 1-Figure 4 As shown, specifically, the workpiece positioning mechanism is composed of a fixed frame 10 connected to the column of the grinding machine, a sliding drive module arranged on one side of the fixed frame 10, a mobile frame 20 arranged on one side of the fixed frame 10 and connected to the sliding drive module, and a positioning assembly 30 arranged at one end of the mobile frame 20, wherein the mobile frame 20 can make a linear reciprocating motion with the sliding drive module, mainly by driving the movement of the mobile frame 20 through the sliding drive module, and the mobile frame 20 then drives the electric positioning assembly 30 to push the workpiece to the desired position.

[0030] Among them, the sliding drive module includes a transmission cylinder 41 and a linear guide rail 42. The transmission cylinder 41 is used to drive the moving frame 20 to reciprocate linearly. The moving frame 20 moves along the linear guide rail 42. The transmission cylinder 41 adopts a rodless cylinder structure, which can cooperate with the linear guide rail 42 to ensure the stability and straightness of the operation.

[0031] Here, a plurality of weight-reducing holes 11 are provided in the middle of the fixed frame 10, and a plurality of weight-reducing holes 21 are provided in the middle of the movable frame 20. The position of the transmission cylinder 41 corresponds to the positions of the weight-reducing holes 11 and 21, that is, the transmission cylinder 41 is located in the middle of the fixed frame 10 and the movable frame 20.

[0032] At the same time, a cylinder seat 51 is arranged on one side of the movable frame 20, and a driving cylinder 52 is arranged on the cylinder seat 51. A positioning piece is arranged at the output end of the driving cylinder 52. The positioning piece moves with the driving cylinder 52 and can abut against the fixed frame 10. The positioning piece is a pin structure, which is connected to the output end of the driving cylinder 52 and is used to abut against the fixed frame 10 to provide resistance and prevent the movable frame from retreating in the transmission direction when loading the workpiece.

[0033] In addition, two limit blocks 61 are provided on one end face of the fixed frame 10, and a hydraulic buffer 63 is provided on the limit block 61. A buffer block 62 is provided on the other side of the mobile frame 20, and the buffer block 62 can move between the two limit blocks 61. The hydraulic buffer 63 is used to contact and cooperate with the buffer block 62, that is, the two limit blocks 61 limit the limit movement range of the mobile frame 20, and buffering is achieved by the hydraulic buffer 63. The hydraulic buffer is a conventional spare part in the field and is not further limited here.

[0034] In addition, the positioning assembly 30 is used to receive the workpiece, and the positioning assembly 30 includes a connecting plate 31, an X-axis positioning plate 32 and a Z-axis positioning plate 33. The connecting plate 31 is connected to the movable frame 20, and the Z-axis positioning plate 33 is connected to the connecting plate 31 and is perpendicular to the movement direction of the movable frame 20. The X-axis positioning plate 32 is arranged on one side of the Z-axis positioning plate 33.

[0035] Among them, the Z-axis positioning plate 33 includes a lower end face and an upper end face that are relatively arranged, the lower end face is parallel to the bottom face of the movable frame 20, and the upper end face is higher than the top face of the fixed frame 10, and the X-axis positioning plate 32 is arranged on the upper end face of the Z-axis positioning plate 33.

[0036] Among them, the connecting plate 31 is generally L-shaped, the Z-axis positioning plate 33 is a straight plate structure, the X-axis positioning plate 32 is equal in length to one side of the Z-axis positioning plate 33 and is higher than the supporting surface of the Z-axis positioning plate 33, and the workpiece is supported by the X-axis positioning plate 32 and the Z-axis positioning plate 33.

[0037] When the utility model is in use, the workpiece is arranged on the positioning assembly 30, the sliding drive module is controlled, and the movable frame 20 is controlled to drive the workpiece to move to the desired position for clamping. At this time, the driving cylinder 52 drives the positioning piece to extend and abut against the fixed frame 10. After the clamping is completed, the positioning piece and the movable frame 20 can be retracted.

[0038] All the methods described herein can be performed in any suitable order. Any and all examples used, or exemplary language provided herein (such as "for example") are merely to better illustrate the present invention, and are not intended to limit the scope of the present invention, unless the claims are included.
