Abstract
Description
Technical Field
[0001] This utility model relates to the field of parts cutting technology, and in particular to a guide rod cutting device. Background Technology
[0002] Currently, when processing some transmission components for automobiles, it is necessary to cut the material into segments of smaller length. Since it is impossible to ensure that the cut edges are flush during the cutting process, it is necessary to grind the cut edges of each segment after cutting to ensure their flatness. This results in low production efficiency and is not conducive to the mass production of parts. Utility Model Content

[0027] In one embodiment, the guide rod cutting device further includes a limiting rod, which is disposed in the sliding cavity and extends along the X direction. Two limiting rods are provided, and the two limiting rods are arranged at intervals along the Y direction.
[0028] The first rod has a first guide hole through it along the X direction, and the second rod has a second guide hole through it along the X direction. The two limiting rods are respectively inserted into the first guide hole and the second guide hole.
[0029] In one embodiment, the guide rod cutting device further includes:
[0030] A constraint groove is provided on one side of the seat body along the X-direction; and

The cutting component is then moved from the initial position to the cutting position, and the above process is repeated to achieve the cutting operation of the guide rod. During the cutting process, because the guide rod passes through the first and second through holes, and the inner diameters of the first and second through holes match the outer diameter of the guide rod, the outer periphery of the guide rod is tightly fitted to the inner wall of the through holes, providing good stability during cutting, ensuring the flatness of the guide rod cut, and improving production efficiency.

[0061] Currently, when processing some transmission components for automobiles, it is necessary to cut the material into smaller segments, and then chamfer the edges of each segment (to complete the processing step). When cutting the guide rod, the guide rod passes through the hole of the cutting tool, and the guide rod is cut off by moving the cutting tool left and right. In the above operation, in order to ensure that the guide rod can smoothly enter the hole of the cutting tool, the inner diameter of the hole needs to be set to be larger (that is, larger than the outer diameter of the guide rod), so that the guide rod can smoothly enter the hole and be cut by moving the cutting tool left and right. In the above cutting process, because the inner diameter of the hole is larger than the outer diameter of the guide rod, residual burrs are easily generated at the cut. The cut needs to be manually ground afterward to ensure the flatness of the cut, resulting in low production efficiency and being unfavorable for the mass production of parts.
[0062] Based on this, refer to Figure 1 , Figure 2 , Figure 3 As shown, this application embodiment provides a guide rod cutting device with intersecting X, Y, and Z directions, used to cut guide rods 6 pre-cut with chamfered grooves 61, such as... Figure 12 The diagram shows the structure of the guide rod 6. The chamfer 61 includes a first chamfer 611, a second chamfer 613, a third chamfer 613, and a fourth chamfer 614. The part where the guide rod 6 is cut is located between the third chamfer 613 and the fourth chamfer 614, that is, as shown in the diagram. Figure 12The position indicated by the dashed line.
[0063] In this embodiment, the guide rod cutting device includes a base 1 and a cutting assembly 2. The base 1 has a first through hole 11 extending along the X direction. The cutting assembly 2 is movably connected to the base 1 along the Y direction, and has a second through hole 21 extending along the X direction. The first through hole 11 and the second through hole 21 match the outer diameter of the guide rod 6, meaning their inner diameters are consistent with the outer diameter of the guide rod 6. A cutting portion is formed on the side of the second through hole 21 facing the first through hole 11, and the first through hole 11 and the second through hole 21 are arranged in contact on opposite sides. Since this solution involves cutting a guide rod 6 with a pre-cut chamfered groove 61, and the cutting portion is located in a position such as... Figure 12 The position between the third chamfered portion 613 and the fourth chamfered portion 614 shown in the diagram allows the inner diameters of the first through hole 11 and the second through hole 21 to be consistent with the outer diameter of the guide rod 6. With this configuration, when the guide rod 6 is inserted into the first through hole 11 and the second through hole 21, the fourth chamfered portion 614 at the cut can easily insert the guide rod 6 into the second through hole 21 (the fourth chamfered portion 614 has a certain slope towards the side facing the second through hole 21, which facilitates the insertion of the guide rod 6 into the second through hole 21).
[0064] In this embodiment, as Figure 9 As shown, in the Y direction, the cutting component 2 has an initial position. At this time, the second through hole 21 on the cutting component 2 and the first through hole 11 on the base 1 correspond to each other in the X direction, that is, they are coaxially arranged. This allows the guide rod 6 to be cut to pass through the first through hole 11 and the second through hole 21 in sequence. Figure 10 As shown, the Y-axis cutting component 2 has a cutting position, which drives the cutting component 2 to move a preset distance from the initial position to the cutting position in the Y-axis, thereby completing the cutting process of the guide rod 6 passing through the first through hole 11 and the second through hole 21.
[0065] In this embodiment, since the diameters of the first perforation 11 and the second perforation 21 match the outer diameter of the guide rod 6 to be cut, the positioning accuracy of the guide rod 6 can be improved when the guide rod 6 passes through the first perforation 11 and the second perforation 21 (so that the outer periphery of the guide rod 6 can fit tightly against the inner wall of the second perforation 21 and the first perforation 11). Thus, when the cutting assembly 2 moves along the Y direction, the guide rod 6 is cut off through the cutting part of the second perforation 21 facing the first perforation 11 (the cutting part is the end position of the second perforation 21 facing the first perforation 11). During the cutting process, the outer periphery of the guide rod 6 fits tightly against the inner wall of the perforation, ensuring that there is no gap between the guide rod 6 and the perforation, thereby ensuring the flatness of the cut during cutting.
[0066] In this embodiment, after the cutting component 2 moves from the initial position to the cutting position, the guide rod 6 is cut (the cut guide rod 6 is removed from the second through hole 21). Then, the cutting component 2 is driven to move from the cutting position back to the initial position, so that the second through hole 21 and the first through hole 11 on the base 1 are once again coaxial. This allows the guide rod 6, which is inserted into the first through hole 11, to be advanced forward and enter the second through hole 21, and then extend outward from the second through hole 21 a predetermined distance (e.g., ...). Figure 2 (as shown); then drive the cutting component 2 along the Y direction to move it from the initial position to the cutting position, and complete the cutting operation again; repeat the above process to realize the continuous cutting of the guide rod 6 and cut a long guide rod 6 into multiple rods with preset lengths.
[0067] It is understandable that when the guide rod 6 is inserted into the second through hole 21, the third chamfered portion 613 and the fourth chamfered portion 614 on the guide rod 6 should be positioned such that (i.e., as shown in the image) Figure 12 The cutting line shown is located on the contact surface between the first through hole 11 and the second through hole 21. Thus, by moving the cutting assembly 2 left and right, the guide rod 6 is cut at the connection between the third chamfered part 613 and the fourth chamfered part 614.
[0068] Reference Figure 2 , Figure 5 , Figure 6 As shown, in one embodiment of this application, the cutting assembly 2 includes a rod 22 and a limiting block 23; wherein the rod 22 is slidably mounted on the base 1 along the Y direction, thereby realizing the position switching between the initial position and the cutting position, as shown. Figure 2 As shown, the second through hole 21 is provided through the rod 22 along the X direction; the limiting block 23 is movably connected to the base 1 along the Y direction, and the limiting block 23 is connected to the rod 22, thereby realizing synchronous movement with the rod 22; as shown Figure 9 , Figure 10 As shown, in the Y direction, the limiting block 23 has a first position and a second position. It can be understood that the first position and the second position are the maximum distance that the limiting block 23 can move along the Y direction. When the limiting block 23 is in the first position, the rod 22 is in the initial position. When the limiting block 23 moves from the first position to the second position, the rod 22 moves from the initial position to the cutting position and performs the cutting operation on the guide rod 6.
[0069] In this embodiment, by moving the limiting block 23 along the Y direction and connecting the limiting block 23 to the rod 22, the range of movement of the rod 22 relative to the base 1 along the Y direction is realized, ensuring that the rod 22 can be accurately positioned in the initial position relative to the base 1 (for aligning the positions of the first through hole 11 and the second through hole 21 so that the guide rod 6 can enter the second through hole 21 from the first through hole 11) and in the cutting position (for cutting the guide rod 6). Since the rod 22 is connected to the limiting block 23, and the limiting block 23 can only move relative to the base 1 along the Y direction between the first position and the second position, the movement of the rod 22 relative to the base 1 can be accurately controlled, and it can be accurately positioned in the initial position and the cutting position.
[0070] Reference Figure 3 , Figure 4 As shown in one embodiment of this application, the guide rod cutting device further includes a sliding cavity and a constraint cavity; wherein, the sliding cavity is disposed through the base 1 along the Y direction, the rod 22 is movably assembled in the sliding cavity along the Y direction, and both ends of the rod 22 along the Y direction extend at least partially outward from the sliding cavity; the constraint cavity is disposed in the base 1 and extends along the Y direction, and is used to allow the limiting block 23 to be slidably assembled in the constraint cavity along the Y direction. It can be understood that the length of the constraint cavity along the Y direction should satisfy: when the limiting block 23 abuts against one side wall of the constraint cavity along the Y direction, the limiting block 23 is in a first position; when the limiting block 23 abuts against the other side wall of the constraint cavity along the Y direction, the limiting block 23 is in a second position; the constraint cavity is at least partially connected to the sliding cavity, thereby allowing the limiting block 23 and the rod 22 to be connected.
[0071] In this embodiment, the two ends of the sliding cavity along the Y direction are respectively provided through the base 1, so that the two ends of the rod 22 along the Y direction extend outward from the sliding cavity. For example, one end of the rod 22 that can extend outward from the sliding cavity can be connected to an external driving component for driving the rod 22 to move along the Y direction, that is, so that the rod 22 can reciprocate between the cutting position and the initial position in the Y direction, and realize the cutting operation of the guide rod 6. It can be understood that the distance of the two ends of the rod 22 extending outward from the sliding cavity along the Y direction should satisfy: regardless of whether the rod 22 is in the cutting position or the initial position, at least one end of the rod 22 along the Y direction can be in the state of extending outward from the sliding cavity, so as to ensure that one end of the rod 22 along the Y direction can be connected to the external driving component.
[0072] It is understandable that the drive component can be a linear motor, a telescopic rod, or other components, and the telescopic end of the linear motor or the telescopic rod is connected to the end of the rod 22 along the Y direction. The control system controls the linear motor and the telescopic rod to move according to the preset telescopic amount, thereby driving the rod 22 to move back and forth between the cutting position and the initial position.
[0073] Reference Figure 5 , Figure 6 , Figure 7 As shown, in one embodiment of this application, the rod 22 includes a first rod 221 and a second rod 222; wherein, the first rod 221 is slidably assembled in a sliding cavity along the Y direction, and the second rod 222 is also slidably assembled in a sliding cavity along the Y direction; the first rod 221 and the second rod 222 are joined together on opposite sides, thereby forming the aforementioned rod 22; as Figure 7 As shown, the first rod 221 has a first semi-groove 211 on the side facing the second rod 222, and the second rod 222 has a second semi-groove 212 on the side facing the first rod 221. When the first rod 221 and the second rod 222 are assembled to form the rod body 22, the first semi-groove 211 and the second semi-groove 212 are assembled to form the second through hole 21. Both the first rod 221 and the second rod 222 are connected to the limiting block 23. This allows the limiting block 23 to move synchronously within the constraint cavity when the rod body 22 moves along the Y direction within the sliding cavity. This constrains and limits the range of movement of the rod body 22 along the Y direction within the sliding cavity, ensuring that the rod body 22 can be accurately positioned in the initial or cutting position.
[0074] In this embodiment, the rod body 22 includes two spliced and connected first rod 221 and second rod 222. This means that when the first rod 221 or the second rod 222 is damaged, only the damaged rod needs to be replaced, without replacing the entire rod body 22, which helps to reduce the later use and maintenance costs.
[0075] Reference Figure 7 As shown, in one embodiment of this application, the first rod 221 has a recessed portion 2211 on the side facing the second rod 222, and a first semi-groove 211 is provided on the side wall of the recessed portion 2211 away from the second rod 222; the second rod 222 has a protruding portion 2221 on the side facing the first rod 221, and a second semi-groove 212 is provided on the side wall of the protruding portion 2221 facing the first rod 221; in the Z direction, a first insertion hole 2212 is provided through the first rod 221 located on both sides of the recessed portion 2211 along the Z direction, and a second insertion hole 2222 is provided through the protruding portion 2221; the positional relationship between the first insertion hole 2212 and the second insertion hole 2222 should satisfy the following: when the first rod 221 and the second rod 222 are assembled to form the rod body 22, the first insertion hole 2212 and the second insertion hole 2222 are corresponding in the Z direction; as Figure 5 , Figure 6 , Figure 8As shown, the limiting block 23 has a rod 231 extending along the Z direction on the side facing the rod 22. The rod 231 is inserted into the first insertion hole 2212 and the second insertion hole 2222 in sequence, thereby connecting the first rod 221, the second rod 222 and the limiting block 23, and enabling the limiting block 23 to move synchronously along the Y direction in the constraint cavity when the rod 22 moves in the sliding cavity along the Y direction. It can be understood that the outer diameter of the rod 231 should be consistent with the inner diameter of the first insertion hole 2212 and the second insertion hole 2222 to ensure the synchronicity of the movement of the rod 22 and the limiting block 23.
[0076] In this embodiment, by providing a recessed portion 2211 on the side of the first rod 221 facing the second rod 222 and a protruding portion 2221 on the side of the second rod 222 facing the first rod 221, the protruding portion 2221 can be inserted into the recessed portion 2211 when the first rod 221 and the second rod 222 are assembled to form the rod body 22. This also aligns the first insertion hole 2212 and the second insertion hole 2222 in the Z direction, allowing the insertion rod 231 connected to the limiting block 23 to be inserted sequentially. Inserted into the first insertion hole 2212 and the second insertion hole 2222, the connection between the first rod 221, the second rod 222 and the limiting block 23 can be realized. On the one hand, the first rod 221 and the second rod 222 are connected into a whole structure. On the other hand, the movement of the rod 22 formed by the first rod 221 and the second rod 222 in the sliding cavity will synchronously drive the limiting block 23 to move in the constraint cavity, so that the rod 22 can move precisely between the cutting position and the initial position.
[0077] Understandably, when maintenance or upkeep of the rod 22 is required, simply remove the insert 231 from the first insertion hole 2212 and the second insertion hole 2222 to separate the first rod 221 and the second rod 222, thereby enabling maintenance or replacement of the first rod 221 and the second rod 222.
[0078] Reference Figure 11 , Figure 12 , Figure 13 As shown, in one embodiment of this application, in the X direction, the second perforation 21 has a small-diameter end close to the first perforation 11 and a large-diameter end away from the first perforation 11, and a conical surface is formed between the small-diameter end and the large-diameter end (the radial dimension of the small-diameter end can be between the radial dimension of the connection between the third chamfered portion 613 and the fourth chamfered portion 614 and the radial dimension of the outer periphery of the guide rod 6). With the above arrangement, when the guide rod 6 is in the cutting position, the tightness of the outer periphery of the guide rod 6 located at the cutting line and the inner wall of the second perforation 21 can be further improved, so that when the rod body 22 is moved along the Y direction and the guide rod 6 is cut, the flatness of the cut can be further improved.
[0079] In this embodiment, after one cut is completed, the end of the guide rod 6 located in the first through hole 11 has a fourth chamfer 614, thereby enabling the guide rod 6 located in the first through hole 11 to be smoothly fed into the second through hole 21 through the inclined surface of the fourth chamfer 614 when conveying it into the second through hole 21; as Figure 11 As shown, when the guide rod located in the first through hole 11 is conveyed into the second through hole 21, the fourth chamfered portion 614 of the guide rod located in the first through hole 11 is first sent into the second through hole 21. During the process of the fourth chamfered portion 614 entering the second through hole 21, since the outer diameter of the guide rod located behind the fourth chamfered portion 614 is larger than the radial dimension of the small diameter end, it will squeeze and compress the periphery of the guide rod 6 to a certain extent (causing a small amount of compression deformation on the periphery of the guide rod 6), thereby allowing the guide rod located behind the fourth chamfered portion 614 to enter the second through hole 21.
[0080] Reference Figure 3 , Figure 4 As shown, in one embodiment of this application, the guide rod cutting device further includes a constraint groove 12, a sliding groove 13, and a stop plate 3; wherein the constraint groove 12 is disposed on one side of the base 1 along the X direction, and the sliding groove 13 is disposed on the same side as the constraint groove 12; it can be understood that, in the Z direction, the constraint groove 12 can be disposed above or below the sliding groove 13; as Figure 1 As shown, a stop plate 3 is detachably connected to one side of the base 1 where the constraint groove 12 and the sliding groove 13 are provided. The stop plate 3 is used to block the constraint groove 12 and the sliding groove 13, so that the space enclosed between the constraint groove 12 and the stop plate 3 forms a constraint cavity, and the space enclosed between the sliding groove 13 and the stop plate 3 forms a sliding cavity. This allows the limiting block 23 to be restricted in the constraint cavity and the rod 22 to be restricted in the sliding cavity, ensuring the stability of the movement of the above components.
[0081] In this embodiment, by detachably connecting the stop plate 3 to the side of the base 1 where the constraint groove 12 and the sliding groove 13 are provided, it is possible to remove the stop plate 3 from the base 1 when maintenance or replacement of the rod 22 and the limiting block 23 is required, so that the constraint cavity and the sliding cavity are in an unsealed state, and the limiting block 23 and the rod 22 can be taken out from the constraint cavity and the sliding cavity. When maintenance or replacement of the limiting block 23 and the rod 22 is completed, the limiting block 23 and the rod 22 are installed into the constraint groove 12 and the sliding groove 13 in sequence, and then the stop plate 3 is installed on the base 1, thereby sealing the constraint groove 12 and the sliding groove 13, and restricting the limiting block 23 and the rod 22 within the constraint cavity and the sliding cavity.
[0082] In this embodiment, when the stop plate 3 is connected to the seat 1, the side wall of the stop plate 3 facing the seat 1 can be in contact with the side wall of the limiting block 23 and the rod 22, thereby ensuring the stability of the limiting block 23 and the rod 22 when they move in the constraint cavity and the sliding cavity.
[0083] In this embodiment, the constraint groove 12 and the slide groove 13 are at least partially connected, thereby enabling the insertion rod 231 connected to the limiting block 23 to enter the slide groove 13 and be inserted into the first insertion hole 2212 and the second insertion hole 2222, so as to realize the connection between the limiting block 23 and the first rod 221 and the second rod 222.
[0084] Reference Figure 3 , Figure 4 As shown, in one embodiment of this application, the guide rod cutting device further includes a mounting groove 14 and a bearing block 4; wherein, the mounting groove 14, the sliding groove 13, and the constraint groove 12 are located on the same side, and the mounting groove 14 in the Z direction is located on the side of the constraint groove 12 opposite to the sliding groove 13, and the mounting groove 14 is connected to the constraint groove 12; Figure 3 , Figure 4 As shown, in the Z direction, the end of the mounting groove 14 away from the constraint groove 12 passes through the base body 1; a bearing block 4 is slidably assembled in the mounting groove 14 along the Z direction, as shown. Figure 5 , Figure 6 As shown, the limiting block 23 is slidably installed at the bottom of the bearing block 4 along the Y direction, thereby enabling the limiting block 23 to move along the Y direction within the constraint cavity and to switch between the first position and the second position.
[0085] It is understandable that the support block 4 installed in the mounting groove 14 is designed to provide a carrier for the sliding arrangement of the limiting block 23 along the Y direction; such as Figure 8 As shown, a groove structure extending in the Y direction is provided on the bottom wall of the support block 4, and a sliding member extending in the Y direction is provided on the side of the limiting block 23 facing the support block 4. The sliding member is slidably assembled in the groove structure, thereby realizing the sliding installation of the limiting block 23 on the support block 4. It can be understood that, in order to prevent the limiting block 23 from detaching from the support block 4, when setting the groove structure and the sliding member, the sliding member can slide into the groove structure in the Y direction, but cannot exit from the groove structure in the Z direction, thereby ensuring the sliding assembly between the limiting block 23 and the support block 4.
[0086] In this embodiment, when the bearing block 4 is installed in the mounting groove 14, the space enclosed by the side of the bearing block 4 facing the rod 22 and the rod 22 constitutes the aforementioned constraint groove 12; it can be understood that the side of the limiting block 23 facing the rod 22 may abut against the upper surface of the rod 22, or may not abut against the upper surface of the rod 22 (e.g. Figure 9 , Figure 10(As shown); When the side of the limiting block 23 facing the rod 22 does not abut against the upper surface of the rod 22, in order to ensure that the bearing block 4 can be stably located in the mounting groove 14, the size of the outer diameter of the insertion rod 231 can be adjusted. That is, the outer diameter of the end of the insertion rod 231 near the limiting block 23 is slightly larger than the outer diameter of the end away from the limiting block 23. Thus, when the insertion rod 231 is inserted into the first insertion hole 2212 and the second insertion hole 2222, when the end of the insertion rod 231 with the larger outer diameter moves to the first insertion hole 2212 at the top, it cannot continue to move because the outer diameter is larger than the inner diameter of the first insertion hole 2212. This ensures that the limiting block 23 does not contact the upper surface of the rod 22, and the bearing block 4 can be stably installed in the mounting groove 14.
[0087] In this embodiment, as Figure 1 As shown, when the stop plate 3 is connected to the base 1, the stop plate 3 will at least partially block the mounting groove 14, thereby further improving the arrangement stability of the bearing block 4 in the mounting groove 14. That is, the end of the mounting groove 14 near the constraint groove 12 is at least partially blocked by the stop plate 3.
[0088] In this embodiment, in order to facilitate the disassembly and assembly of the rod 22, the limiting block 23, and the bearing block 4, the constraint groove 12 is located above the slide groove 13 and the mounting groove 14 is located above the constraint groove 12. This facilitates the operator's disassembly and assembly of the bearing block 4 and the limiting block 23, thereby reducing the user's disassembly and assembly time and improving the efficiency of subsequent maintenance and replacement of the equipment.
[0089] Reference Figure 3 As shown, in one embodiment of this application, the guide rod cutting device further includes a limiting rod 5, which is disposed within the sliding cavity and extends along the X direction. Two limiting rods 5 are provided, and the two limiting rods 5 are arranged at intervals along the Y direction; Figure 2 , Figure 5 , Figure 7 As shown, the first rod 221 has a first guide hole 2213 extending through it in the X direction, and the second rod 222 has a second guide hole 2223 extending through it in the X direction. The two limiting rods 5 are correspondingly inserted into the first guide hole 2213 and the second guide hole 2223. The outer diameter of the limiting rod 5 is consistent with the size of the first guide hole 2213 and the second guide hole 2223 in the Z direction. This achieves that when the first rod 221 and the second rod 222 move in the sliding cavity, the guiding cooperation between the limiting rod 5 and the first guide hole 2213 and the second guide hole 2223 can further improve the stability of the rod 22 when it moves in the Y direction in the sliding cavity.
[0090] It is understandable that, such as Figure 1As shown, a clearance hole 31 extending through the X direction should be provided on the stop plate 3 to allow the end of the guide rod 6 to extend outward from the stop plate 3 and the limiting rod 5 to extend outward from the stop plate 3, so as to allow the guide rod 6 and the limiting rod 5 to extend outward to make way.
[0091] Reference Figure 1 As shown in one embodiment of this application, the stop plate 3 is connected to the base 1 by fasteners. It can be understood that the fasteners can be bolts, pins, etc.
