Description

Technical Field

[0001] The utility model relates to the field of edge grinding machines, in particular to an edge grinding machine. Background Art

[0002] At present, edge grinding machines generally use a double-pressure belt structure to process the workpiece. Its main feature is that the synchronous belts of the double-sided crossbeam 2' and the synchronous belts of the double-sided pressure beam 1' simultaneously clamp the workpiece 10' up and down and convey it. During the conveying process, the grinding head 3' driven by the motor installed on the crossbeam 2' grinds both sides of the workpiece 10'. Among them, the two pressure beams 1' are respectively installed on the corresponding crossbeam 2' through the rotating arm device, and the two crossbeams 2' are driven and adjusted by the width adjustment device so that they move symmetrically closer or farther away from each other, thereby adjusting the distance between the two crossbeams to achieve processing of workpieces of different lengths, such as Figure 1 However, due to the size of the pressure belt on the pressure beam and the transmission belt on the crossbeam, the minimum processing distance between the two crossbeams is limited. Therefore, this double-belt edge grinding machine can only process workpieces longer than 150mm and cannot process workpieces shorter than 150mm. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide an edge grinding machine which can process workpieces of smaller size.

[0004] In order to solve the above technical problems, the utility model provides an edge grinding machine for processing a workpiece, comprising a frame and a first edge grinding device, a second edge grinding device and a supporting and pressing device installed on the frame, wherein the first edge grinding device and the second edge grinding device are respectively arranged on opposite sides of the supporting and pressing device;

[0005] The first edging device includes a first edging mechanism, and the second edging device includes a second edging mechanism; the supporting and pressing device includes a supporting and conveying mechanism and a pressing beam mechanism; the pressing beam mechanism is arranged above the supporting and conveying mechanism, and the first edging mechanism and the second edging mechanism are respectively arranged on opposite sides of the supporting and conveying mechanism;

[0006] The pressing beam mechanism can move to press the workpiece onto the supporting and conveying mechanism; the first edge grinding mechanism and the second edge grinding mechanism can move to approach or move away from the workpiece.

[0007] As an improvement to the above scheme, the first edge grinding device also includes a first support beam, the first edge grinding mechanism is installed on the frame through the first support beam, and the supporting and clamping device is arranged on the first support beam; the second edge grinding device also includes a second support beam, and the second edge grinding mechanism is installed on the frame through the second support beam; the first support beam and the second support beam are respectively arranged on opposite sides of the frame.

[0008] As an improvement to the above solution, the first support beam is fixedly connected to the frame via a first support seat, and the second support beam is movably connected to the frame via a second support seat; the first support seat and the second support seat are arranged on opposite sides of the frame.

[0009] As an improvement to the above solution, it further includes an adjustment mechanism provided on the frame, and the second support seat is movably connected to the frame through the adjustment mechanism.

[0010] As an improvement of the above scheme, the adjustment mechanism includes a power mechanism and a transmission assembly. The power mechanism is arranged on the frame, and the power mechanism is connected to the second support seat through the transmission assembly. The power mechanism is connected to the transmission assembly, and the transmission assembly is connected to the second support seat.

[0011] As an improvement to the above solution, a guide shaft is provided on the frame, the first support seat is fixedly arranged on the guide shaft, and the second support seat is slidably arranged on the guide shaft.

[0012] As an improvement to the above solution, the number of the second support bases is at least two;

[0013] The adjustment mechanism further includes a coupling mechanism, and the power mechanism is connected to the two second support seats respectively through the coupling mechanism, so that the second support seats move synchronously.

[0014] As an improvement to the above solution, the width of the supporting and pressing device is smaller than the length of the workpiece.

[0015] As an improvement of the above solution, the first edge grinding mechanism and the second edge grinding mechanism have the same structure, both including a grinding wheel, a grinding motor, a feed motor and a slide rail assembly, the grinding wheel is connected to the grinding motor, the grinding motor is connected to the feed motor, and the grinding motor is slidably connected to the slide rail assembly.

[0016] As an improvement of the above solution, the pressure beam mechanism includes a pressure beam and a lifting mechanism, and the lifting mechanism drives the pressure beam to press the workpiece onto the supporting and conveying mechanism.

[0017] The implementation of this utility model has the following beneficial effects:

[0018] This new edge grinding machine uses a support and clamping device to unilaterally clamp the workpiece. Two edge grinding mechanisms are located on either side of the support and clamping device, processing the two ends of the workpiece respectively. The positions of the two edge grinding mechanisms relative to the ends of the workpiece can be adjusted according to the length of the workpiece. This single-sided clamping method solves the problem of being unable to process smaller workpieces due to the size limitations of the two drive belts and the pressure belt, and can process workpieces over 60mm in length.

[0023] To make the objectives, technical solutions, and advantages of the present invention more clearly apparent, the present invention will be further described in detail below with reference to the accompanying drawings. It is hereby stated that any directional terms such as "up," "down," "left," "right," "front," "back," "inside," and "outside" that appear or will appear in this document are based solely on the accompanying drawings and are not intended to limit the present invention.

[0024] See also Figure 2-4 The utility model discloses an edge grinding machine for processing a workpiece 100, comprising a frame 1 and a first edge grinding device, a second edge grinding device and a supporting and pressing device installed on the frame 1, wherein the first edge grinding device and the second edge grinding device are respectively arranged on opposite sides of the supporting and pressing device.

[0025] The first edging device includes a first edging mechanism 2, and the second edging device includes a second edging mechanism 5. The first edging mechanism 2 and the second edging mechanism 5 are symmetrically arranged on opposite sides of the support and clamping device. The support and clamping device includes a support and conveying mechanism 8 and a pressure beam mechanism 9; the pressure beam mechanism 9 is arranged above the support and conveying mechanism 8, and the first edging mechanism 2 and the second edging mechanism 5 are respectively arranged on opposite sides of the support and conveying mechanism 8.

[0026] The pressing beam mechanism 9 can move to press the workpiece 100 onto the supporting and conveying mechanism 8 ; the first edge grinding mechanism 2 and the second edge grinding mechanism 5 can move to approach or move away from the workpiece 100 .

[0027] This new edge grinding machine uses a support and clamping device to unilaterally clamp the workpiece. Two edge grinding mechanisms are located on either side of the support and clamping device, processing the two ends of the workpiece respectively. The positions of the two edge grinding mechanisms relative to the ends of the workpiece can be adjusted according to the length of the workpiece. This single-sided clamping method solves the problem of being unable to process smaller workpieces due to the size limitations of the two drive belts and the pressure belt, and can process workpieces over 60mm in length.

[0028] Specifically, the first edging device further includes a first support beam 3, through which the first edging mechanism 2 is mounted on the frame 1, and the support and clamping device is provided on the first support beam 3. The second edging device further includes a second support beam 6, through which the second edging mechanism 5 is mounted on the frame 1. The first support beam 3 and the second support beam 6 are respectively provided on opposite sides of the frame 1. The provision of the first support beam and the second support beam ensures that the first and second edging mechanisms are securely and reliably mounted on the frame, thereby ensuring the reliability of the edging mechanisms in processing the workpiece.

[0029] More specifically, the first support beam 3 is fixedly connected to the frame 1 via the first support base 4, and the second support beam 6 is movably connected to the frame 1 via the second support base 7. The first support base 3 and the second support base 4 are disposed on opposite sides of the frame 1. The provision of the first and second support bases ensures reliable connection between the first and second support beams and the frame, thereby ensuring reliable installation of the first and second edge grinding mechanisms.

[0030] The first edging mechanism and the supporting and holding device are both mounted on the first support beam, thereby maintaining a fixed position relative to the workpiece. The first support beam is fixedly connected to the machine frame via the first support seat, thereby securing the first edging mechanism and the supporting and holding device to the machine frame. The second edging mechanism is mounted on the second support beam, while the second sprocket beam is movably connected to the machine frame via the second support seat. This allows the second edging mechanism to move relative to the first edging mechanism, i.e., move closer to or further away from the first edging mechanism, facilitating workpiece installation, machine maintenance, and adjusting its relative position to the workpiece based on its size.

[0031] Furthermore, the present invention further includes an adjustment mechanism provided on the frame 1, through which the second support base 7 is movably connected to the frame 1, and the adjustment mechanism drives the second edge grinding mechanism 5 to move closer to or further away from the workpiece 100. The present invention utilizes the adjustment mechanism to enable the second support base to move on the frame, thereby driving the second support beam and the second edge grinding mechanism closer to or further away from the workpiece, thereby facilitating the installation of the workpiece on the support and clamping device.

[0032] like Figure 3As shown, the adjustment mechanism includes a power mechanism 10 and a transmission assembly. The power mechanism 10 is arranged on the frame 1. The power mechanism 10 is connected to the transmission assembly, and the transmission assembly is connected to the second support seat 7. The power mechanism 10 drives the second support seat 7 through the transmission assembly. The power mechanism 10 is a motor. The transmission assembly includes a screw rod 12 and a screw nut 13. The screw rod and the screw nut are threadedly connected. The screw nut 13 is arranged on the second support seat 7. The power mechanism 10 drives the screw rod 12 to rotate, causing the screw nut 13 to move back and forth along the screw rod 12, driving the second support seat 7 to move back and forth along the screw rod 12, so that the second edging mechanism approaches or moves away from the workpiece, facilitating the installation of the workpiece on the support and clamping device.

[0033] Preferably, the frame 1 is provided with a guide shaft 11, the first support seat 4 being fixedly mounted on the guide shaft 11, and the second support seat 7 being slidably mounted on the guide shaft 11. The guide shaft spans the frame, and the first support seat and the guide shaft are fixedly connected, thereby securing the first edge grinding mechanism, the support and clamping device, and the workpiece to the frame. The second support seat and the guide shaft are slidably connected, allowing the second edge grinding mechanism to move back and forth under the guidance of the guide shaft, ensuring that the second edge grinding mechanism moves in a predetermined direction and ensuring machining accuracy.

[0034] More preferably, there are at least two guide shafts 11, at least two first support bases 4, and at least two second support bases 7. The two first support bases and the two second support bases are mounted on the two guide shafts, respectively. The first support beam is securely mounted on the frame, supported by the two first support bases, and the second support beam is securely mounted on the frame, supported by the two second support bases. This effectively supports the first and second support beams, ensuring reliable movement of the first and second edge grinding mechanisms.

[0035] Furthermore, in order to enable the two second support seats to move synchronously, the adjustment mechanism further includes a coupling mechanism, and the power mechanism 10 is connected to the two second support seats 7 respectively through the coupling mechanism to enable the second support seats 7 to move synchronously. Figure 3 As shown, the coupling mechanism includes a reducer 14, a coupling shaft 15, and a coupling 16. The motor is connected to the first second support seat through the first reducer set, and is connected to the second reducer set and coupling through the coupling shaft through the first reducer set and the coupling. The second reducer set is connected to the second second support seat through the transmission assembly, so that the two second support seats move synchronously, ensuring that both ends of the second support seat move synchronously, thereby ensuring that the second edging mechanism can process the workpiece accurately.

[0036] Preferably, the width of the supporting and clamping device is smaller than the length of the workpiece 100, that is, the width of the supporting and conveying mechanism 8 and the pressure beam mechanism 9 are both smaller than the length of the workpiece 100, so as to avoid interference between the supporting and clamping device and the first edge grinding mechanism and the second edge grinding mechanism to hinder the processing of the workpiece, so that the utility model can process workpieces with shorter lengths as much as possible, thereby expanding the processing range of the utility model.

[0037] Among them, such as Figure 4 As shown, the first and second edge grinding mechanisms 2 and 5 have the same structure, each comprising a grinding wheel 21, a grinding motor 22, a feed motor 23, and a slide rail assembly 24. The grinding wheel 21 is connected to the grinding motor 22, which is connected to the feed motor 23. The grinding motor 22 is slidably connected to the slide rail assembly 24. The grinding motor drives the grinding wheel to rotate to grind the workpiece. The feed motor drives the grinding motor to move along the slide rail assembly, causing the grinding wheel to move closer to or further away from the workpiece. This allows the relative position of the grinding wheel and the workpiece to be adjusted according to the length of the workpiece to accommodate the processing of workpieces of different lengths.

[0038] In addition, the pressure beam mechanism 9 includes a pressure beam (not shown in the figure) and a lifting mechanism (not shown in the figure). The lifting mechanism drives the pressure beam to press the workpiece 100 onto the support and conveying mechanism 8. Specifically, the pressure beam mechanism 9 is arranged above the support and conveying mechanism 8. The support and conveying mechanism 8 is provided with a conveying belt. In addition to supporting the workpiece, the support and conveying mechanism also conveys the workpiece at the same time, so that the workpiece can be transported and processed at the same time. The pressure beam rises or falls under the drive of the lifting mechanism. When the pressure beam is driven to fall, the workpiece can be pressed against the support and conveying mechanism to prevent the workpiece from shifting during the processing process, thereby ensuring the reliability and accuracy of the processing. The support and conveying mechanism and the pressure beam mechanism can adopt the existing technical structure and will not be introduced in detail here.

[0039] In summary, the utility model provides an edge grinding machine that can process workpieces of smaller sizes.

[0040] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications are also considered to be within the scope of protection of the present invention.
