Description

Technical Field

[0001] This utility model relates to the field of guide rail processing technology, and in particular to a feeding mechanism for linear guide rail processing. Background Technology

[0002] Linear guide machining refers to the process of using steel, aluminum alloy, or other materials as blanks and processing them into mechanical parts with high-precision parallelism, straightness, and low surface roughness through processes such as blanking, rough grinding, fine milling, and surface treatment. During the machining process, the linear guides need to be fed by a feeding mechanism to ensure the stability of the machining process and meet the high-precision requirements of subsequent assembly and use.

[0003] In related technical fields, existing feeding mechanisms mainly consist of a linear feeding module and a linear guide clamping mechanism. The clamping mechanism uses a cylinder and a clamping plate to hold and fix the linear guide. However, during the rough grinding or milling process of the linear guide, the cylinder and clamping plate clamping method has poor rigidity. Therefore, once machining vibration occurs, the clamping force is prone to fluctuation, and the clamping plate will experience a certain amount of displacement. This leads to a slight shift in the position of the guide, affecting the machining accuracy of the guide and making it difficult to meet the high requirements for feeding stability during linear guide machining. Utility Model Content

[0004] This utility model aims to at least partially solve one of the technical problems in the related art.

[0005] Therefore, the purpose of this utility model is to propose a feeding mechanism for linear guide rail machining, which adopts a rigid abutment mechanism design to lock the position of the positioning chuck, which can significantly reduce the impact of machining vibration on the position of the linear guide rail and improve the feeding stability during the linear guide rail machining process.

[0006] To achieve the above objectives, this utility model proposes a feeding mechanism for linear guide rail processing, comprising a linear module, a support plate, a linear guide rail body, and two locking devices. The two locking devices are respectively disposed on the slider of the linear module and connected via the support plate. The linear guide rail body is located on the support plate and is locked and limited by the two locking devices. Each locking device includes a clamping assembly, two sets of limiting assemblies, and two sets of abutting assemblies. The two sets of limiting assemblies are symmetrically disposed on the clamping assembly and move along the height direction of the support plate. The two sets of abutting assemblies are symmetrically disposed within the clamping assembly and abut against the limiting assemblies.

[0007] In addition, the feeding mechanism for linear guide rail processing proposed above according to this utility model may also have the following additional technical features: Specifically, the clamping assembly includes a drive unit, a double-ended lead screw, two sliding seats, two connecting seats, a base, and two positioning chucks. The two sliding seats are symmetrically slidably disposed within the base and threadedly connected to the outside of the double-ended lead screw. The drive unit is disposed on the base, and its output end is connected to one end of the double-ended lead screw. The double-ended lead screw is rotatably disposed within the base. The two connecting seats are symmetrically disposed on the two sliding seats, and the two positioning chucks are symmetrically disposed on the two connecting seats.

[0008] Specifically, each set of limiting components includes a top plate, an elastic element, a handle, two support columns, and a limiting seat. The top plate is disposed on the support columns, the limiting seat is slidably disposed on the two support columns, the elastic element is disposed on the support columns and its two ends abut against the top plate and the limiting seat respectively, and the handle is disposed on the limiting seat.

[0009] Specifically, each set of abutment components includes an abutment seat, a drive block, a handwheel, and a threaded rod, wherein the abutment seat is disposed on the drive block, the drive block is threaded onto the threaded rod, and the handwheel is disposed at the end of the threaded rod.

[0010] Compared with the prior art, the technical solution provided by this utility model has the following beneficial effects: This invention ensures the linear motion accuracy of the linear guide body through a linear module, thereby achieving precise feeding of the linear guide body. During the installation of the linear guide body, a clamping assembly is set up, and a driving component drives a double-ended lead screw to rotate, driving two positioning chucks to move towards each other, thereby achieving a clamping operation on the linear guide body and ensuring clamping force. By setting up an abutment assembly, the abutment seat is driven to abut against the limit seat, thereby locking the position of the positioning chucks and ensuring that the linear guide body will not be displaced due to vibration or external force during processing, thus improving processing accuracy and stability.

[0014] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Rather, the embodiments of the present invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0015] The feeding mechanism for linear guide processing according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0016] like Figures 1-5 As shown in the figure, a feeding mechanism for linear guide rail processing according to an embodiment of the present invention includes a linear module 1, a support plate 2, a linear guide rail body 3, and two locking devices. The two locking devices are respectively disposed on the slider of the linear module 1 and connected through the support plate 2.

[0017] It should be noted that the linear module 1 is a dual-slider linear module with a self-locking mechanism inside. This mechanism can automatically lock the slider position when the linear module 1 stops running, preventing the slider from sliding due to external forces, thereby ensuring the positional stability of the linear guide body 3 during the processing.

[0018] The linear guide body 3 is located on the support plate 2 and is locked and limited by two locking devices.

[0019] It should be noted that the support plate 2 is used to support the linear guide body 3, bear the various forces generated by the linear guide body 3 during the processing, and prevent the linear guide body 3 from deforming during the processing.

[0020] The locking device includes a clamping assembly 4, two sets of limiting assemblies 5 and two sets of abutting assemblies 6. The two sets of limiting assemblies 5 are symmetrically arranged on the clamping assembly 4 and move along the height direction of the support plate 2. The two sets of abutting assemblies 6 are symmetrically arranged inside the clamping assembly 4 and abut against the limiting assemblies 5.

[0021] It should be noted that the clamping component 4 is used to firmly clamp the linear guide body 3. After the clamping component 4 initially defines the position of the linear guide body 3, the clamping component 4 abuts against the limiting component 5 through the abutting component 6, thereby locking the position of the clamping component 4 and ensuring that the linear guide body 3 will not be displaced due to vibration or external force during the processing.

[0022] In one embodiment of this utility model, such as Figures 3-4 As shown, the clamping assembly 4 includes a drive unit 41, a double-ended lead screw 42, two sliding seats 43, two connecting seats 44, a base 45, and two positioning chucks 46. The two sliding seats 43 are symmetrically slidably disposed within the base 45 and threadedly connected to the outside of the double-ended lead screw 42. The drive unit 41 is disposed on the base 45, and its output end is connected to one end of the double-ended lead screw 42. The double-ended lead screw 42 is rotatably disposed within the base 45. The two connecting seats 44 are symmetrically disposed on the two sliding seats 43, and the two positioning chucks 46 are symmetrically disposed on the two connecting seats 44.

[0023] It should be noted that the base 45 is fixedly connected to the slider of the linear module 1 by bolts. The base 45 has a groove that matches the size of the sliding seat 43. The sliding seat 43 slides in the groove. The double-ended lead screw 42 is rotatably mounted in the base 45 through bearings. Thus, the sliding seat 43 can move the positioning chuck 46 through the connecting seat 44 under the drive of the double-ended lead screw 42, thereby realizing the clamping action of the linear guide body 3. The cross-section of the positioning chuck 46 is trapezoidal, so that it can be inserted into the grooves on both sides of the linear guide body 3 during the clamping process.

[0024] It is understood that the driving component 41 is a motor. When the driving component 41 is started, its output end drives the double-ended lead screw 42 to rotate. Since the two sliding seats 43 are symmetrically threaded to the outside of the double-ended lead screw 42 and symmetrically slidably arranged in the base 45, the double-ended lead screw 42 can drive the two sliding seats 43 to move towards or away from each other along the slide groove, and then drive the two positioning chucks 46 to move closer or further away through the connecting seat 44, so as to realize the clamping or loosening operation of the linear guide body 3.

[0025] In one embodiment of this utility model, such as Figures 3-4 As shown, each set of limiting components 5 includes a top plate 51, an elastic element 52, a handle 53, two support columns 54, and a limiting seat 55. The top plate 51 is disposed on the support columns 54, the limiting seat 55 is slidably disposed on the two support columns 54, the elastic element 52 is disposed on the support columns 54, and its two ends abut against the top plate 51 and the limiting seat 55 respectively, and the handle 53 is disposed on the limiting seat 55.

[0026] It should be noted that the support column 54 is fixedly connected to the base 45, and the top plate 51 is fixedly connected to the top of the support column 54. The support column 54 is provided with a step to limit the downward displacement distance of the limiting seat 55, so as to ensure that the limiting seat 55 does not move down excessively. The elastic element 52 is a spring and is sleeved on the outside of the support column 54. It is always in a compressed state. Thus, under the push of the elastic element 52, the height position of the limiting seat 55 remains fixed. When it is necessary to adjust the position of the limiting seat 55, the operator can manually pull the limiting seat 55 along the support column 54 to slide upward through the handle 53.

[0027] In one embodiment of this utility model, such as Figure 5 As shown, each set of abutment components 6 includes an abutment seat 61, a drive block 62, a handwheel 63, and a threaded rod 64. The abutment seat 61 is disposed on the drive block 62, the drive block 62 is threaded onto the threaded rod 64, and the handwheel 63 is disposed at the end of the threaded rod 64.

[0028] It should be noted that the top of the connecting seat 44 is provided with a sliding groove that matches the size of the drive block 62. The drive block 62 is slidably disposed in the sliding groove. The threaded rod 64 is rotatably disposed in the connecting seat 44 through a bearing, and one end of it extends to the outside of the connecting seat 44 and is fixed with a handwheel 63. The top of the abutment seat 61 is provided with an inclined surface that cooperates with the limit seat 55. It is understandable that the handwheel 63 drives the threaded rod 64 to rotate, and the threaded rod 64 drives the drive block 62 through the thread on its surface. The drive block 62 drives the abutment seat 61, which in turn makes the abutment seat 61 abut against the limit seat 55 to lock the position of the clamping component 4.

[0029] In practical applications, the linear guide body 3 is first placed on the support plate 2. Then, the drive unit 41 is activated, which drives the double-ended lead screw 42 to rotate. The double-ended lead screw 42 drives the two sliding seats 43 to move towards each other. The connecting seat 44 drives the two positioning chucks 46 to approach each other, achieving initial clamping of the linear guide body 3. During the clamping process, the inclined surface of the abutment seat 61 contacts the limit seat 55 and pushes the limit seat 55 upward, compressing the elastic element 52. When the clamping action is completed, the elastic element 52 pushes the limit seat 55 to reset, and the two abutment seats 61 are located between the two limit seats 55. At this time, the handwheel 63 is turned. Wheel 63 drives threaded rod 64 to rotate. Threaded rod 64 drives drive block 62 through its threads. Drive block 62 drives abutment seat 61 to move towards limit seat 55 until abutment seat 61 abuts against limit seat 55. At this time, the positions of connecting seat 44 and positioning chuck 46 can be locked to ensure that positioning chuck 46 always clamps the linear guide body 3. During processing, the linear guide body 3 will not be displaced due to vibration. At this time, the linear module 1 drives clamping component 4, which drives the linear guide body 3 to move, thereby sending the linear guide body 3 to the processing station for processing.

[0030] After the linear guide body 3 is processed, the operator rotates the handwheel 63 in the opposite direction to separate the abutment seat 61 from the limit seat 55, thereby releasing the position lock of the positioning chuck 46. Then, the operator pulls the limit seat 55 upward through the handle 53, and at the same time starts the drive unit 41 to reverse, so that the two positioning chucks 46 move away from each other. The position limitation of the linear guide body 3 is released. After releasing the handle 53, the linear guide body 3 can be removed from the support plate 2.

[0031] In summary, the feeding mechanism for linear guide rail processing in this embodiment of the utility model ensures the linear motion accuracy of the linear guide rail body through the linear module, thereby achieving precise feeding of the linear guide rail body. When installing the linear guide rail body, by setting up a clamping component, the driving component drives the double-ended lead screw to rotate, driving the two positioning chucks to move towards each other, realizing the clamping operation of the linear guide rail body and ensuring the clamping force. By setting up an abutment component, the abutment seat is driven to abut against the limit seat, thereby locking the position of the positioning chucks and ensuring that the linear guide rail body will not be displaced due to vibration or external force during processing, thus improving processing accuracy and stability.
