Description

Technical Field

[0001] The utility model relates to the technical field of multi-axis drilling, in particular to a guiding device. Background Art

[0002] At present, multi-axis drills are widely used in the metal processing industry. Because multi-axis drills can process multiple holes at the same time, they have the advantages of high efficiency, high output and low cost, and are highly favored by the processing industry.

[0003] Before using a multi-axis machine for machining, it is usually necessary to first drill a guide point on the workpiece to be machined using a center drill, and then use the multi-axis machine to drill holes based on the guide point. However, machining the guide point first and then drilling holes using the multi-axis machine will reduce production efficiency. However, for a multi-axis machine, if there is no guide point, machining directly on the plane will cause the drill bit to easily deviate, making it difficult to ensure the center position of the hole, and thus making it difficult to ensure the machining quality of the part. Utility Model Content

[0004] The technical problem solved by the utility model is to provide a guiding device, which can guide the drill bit on the multi-axis device, so as to ensure the center position of the hole on the workpiece to be processed, so as to improve the processing quality of the parts.

[0005] A guide device for guiding a drill bit on a multi-axis device, the guide device comprising:

[0006] A fixing seat, one end of which is used for fixed connection with the multi-axis device, and the fixing seat is provided with an avoidance passage for the drill bit to pass through;

[0007] A guide sleeve assembly is sleeved on the other end of the fixed seat and is slidably connected to the fixed seat. The guide sleeve assembly is provided with a positioning through hole for guiding the drill bit. The end of the guide sleeve assembly facing away from the fixed seat is provided with a positioning surface, and the positioning through hole is provided on the positioning surface.

[0008] The elastic member is supported between the fixing seat and the guide sleeve assembly to provide elastic force for the guide sleeve assembly to move away from the fixing seat.

[0009] The guiding device provided by the utility model and the beneficial effects produced by the background technology are as follows:

[0010] The above-mentioned guide device is fixedly connected to the fixed seat and the multi-axis device to achieve the fixed connection between the entire guide device and the multi-axis device, and an avoidance channel for the drill bit to pass through is set on the fixed seat to avoid the drill bit on the multi-axis device; the guide sleeve assembly is slidably connected to the fixed seat so that the guide sleeve assembly can move relative to the fixed seat as the drill bit moves, thereby providing necessary space for the movement of the drill bit. By setting a positioning surface on the guide sleeve assembly, when drilling, the multi-axis device drives the drill bit and the guide device to move toward the workpiece to be processed. The positioning surface first contacts the plane where the drill hole of the workpiece to be processed is located, and at this time, the positioning surface positions the guide sleeve assembly. And by setting a positioning through hole on the guide sleeve assembly, the drill bit is positioned and constrained, so that the drill bit will not be offset, thereby ensuring the center position of the drill hole on the workpiece to be processed. An elastic member is provided between the guide sleeve assembly and the fixed seat, so as to provide elastic force for the guide sleeve assembly to move away from the fixed seat. During the drilling process, the elastic member is compressed, and the fixed seat can move toward the guide sleeve assembly; when the drilling is completed, the guide sleeve assembly moves away from the fixed seat under the elastic force of the elastic member. Since the elastic member has elastic force, under the action of the multi-axis device, the guide sleeve assembly can overcome the action of the elastic member and move relative to the fixed seat, thereby ensuring that the drill bit can move normally. Through the above structural form, while ensuring normal drilling, the drill bit can be positioned and constrained to ensure that the drill bit will not deviate, thereby ensuring the center position of the drill hole, and further ensuring the processing quality of the parts.

[0011] In one embodiment, the guide sleeve assembly includes:

[0012] The movable sleeve is configured with a receiving cavity with an opening at one end, the elastic member is arranged in the receiving cavity, the end of the fixing seat away from the multi-axis device is inserted in the receiving cavity, and the end of the movable sleeve away from the fixing seat is provided with a mounting hole communicating with the receiving cavity;

[0013] A guide sleeve is fixed in the mounting hole, the positioning through hole is constructed on the guide sleeve, and the positioning through hole is communicated with the accommodating cavity and the avoidance channel.

[0014] By providing an accommodating cavity at one end of the movable sleeve to accommodate the elastic member, the movable sleeve can also be sleeved on the fixed seat to achieve relative movement of the movable sleeve relative to the fixed seat. By providing a mounting hole on the movable sleeve, the guide sleeve is fixed to the fixed seat. By providing a positioning through hole on the guide sleeve, and connecting the positioning through hole with the avoidance channel and the accommodating cavity, the drill bit can pass through the avoidance channel and the accommodating cavity and pass through the positioning through hole. In the present technical solution, by providing the guide sleeve assembly with a positioning through hole on the guide sleeve, the guide sleeve is fixedly connected to the movable sleeve, so that the guide sleeve and the movable sleeve can be made of two different materials. For example, the guide sleeve can be made of wear-resistant material to increase the service life of the guide sleeve assembly. The movable sleeve can be made of ordinary material, which is easy to process and can reduce production costs.

[0015] In one of the embodiments, a chip removal groove is provided on the movable sleeve along the axial direction of the movable sleeve, the chip removal groove is provided between the accommodating cavity and the guide sleeve, and the chip removal groove passes through along the radial direction of the movable sleeve.

[0016] A chip removal groove is provided between the accommodating cavity and the guide sleeve so that chips generated during drilling can be discharged from the chip removal groove, thereby preventing chips from entering the accommodating cavity and causing the elastic member to get stuck, thereby ensuring that the movable sleeve can slide smoothly relative to the fixed seat.

[0017] In one embodiment, two oppositely disposed recessed portions are disposed on the outer circumference of the movable sleeve, and the recessed portions are recessed toward the axis of the movable sleeve. This arrangement can reduce the weight of the movable sleeve, thereby making the entire guide device lighter and more convenient to use.

[0018] In one embodiment, a portion of the radial sidewall of the accommodating cavity is provided through-through, so that the weight of the movable sleeve can be further reduced while reducing the contact area between the fixed seat and the movable sleeve, thereby reducing the friction between the fixed seat and the movable sleeve.

[0019] In one embodiment, the guiding device further comprises:

[0020] A guide rod has one end fixedly connected to the fixing seat and the other end guided and matched with the movable sleeve.

[0021] In this technical solution, one end of the guide rod is fixedly connected to the fixed seat, and the other end is matched with the movable sleeve guide to guide the relative movement of the movable sleeve and the fixed seat, thereby ensuring that the movement of the movable sleeve and the fixed seat can be smoother and more reliable.

[0022] In one of the embodiments, two first bosses are arranged opposite to each other along the radial direction of the movable sleeve on the outer peripheral surface of the movable sleeve, each of the first bosses is provided with a guide through hole extending along the axial direction of the movable sleeve, and the guide rod is guided and matched with the guide through hole.

[0023] By arranging the first boss on the outer peripheral surface of the movable sleeve and arranging the guide through hole on the first boss, the guide through hole is reasonably arranged while ensuring the structural strength of the movable sleeve.

[0024] In one of the embodiments, the fixing seat is provided with two second bosses arranged opposite to each other, the second bosses correspond to the first bosses one by one, the first bosses are provided with connecting holes, and one end of the guide rod is fixed in the connecting holes.

[0025] By arranging a second boss corresponding to the first boss on the fixing seat, the fixed connection between the guide rod and the fixing seat is achieved while ensuring the structural strength of the fixing seat.

[0026] In one embodiment, a first through hole is further provided on the second boss, the axis of the first through hole is perpendicular to the axis of the connecting hole, a second through hole is provided on the guide rod, the axial direction of the second through hole is perpendicular to the axis of the guide rod, the first through hole and the second through hole correspond to each other, and a fastener passes through the first through hole and the second through hole to fix the guide rod to the first boss.

[0027] In the technical solution, the above structural form not only has a simple structure, but also facilitates the fixed connection between the guide rod and the fixing seat.

[0028] In one embodiment, the fixing base is provided with two connecting lugs, and the connecting lugs are provided with a third through hole for a fastener to pass through, so as to achieve a fixed connection between the fixing base and the multi-axis device. The above structure facilitates the fixed connection between the fixing base and the multi-axis device. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] 1 to 7 , an embodiment of the utility model provides a guide device 100 for guiding a drill bit 200 on a multi-axis device. The guide device 100 includes a fixed seat 110, a guide sleeve assembly 120 and an elastic member 130. One end of the fixed seat 110 is used for fixed connection with the multi-axis device. The fixed seat 110 is provided with an avoidance channel 111 for the drill bit 200 to pass through; the guide sleeve assembly 120 is sleeved on the other end of the fixed seat 110 and is slidably connected to the fixed seat 110. The guide sleeve assembly 120 is provided with a positioning through hole 1221 for guiding the drill bit 200. A positioning surface 1216 is provided at one end of the guide sleeve assembly 120 away from the fixed seat 110, and the positioning through hole 1221 is provided on the positioning surface 1216; the elastic member 130 is supported between the fixed seat 110 and the guide sleeve assembly 120 to provide an elastic force for the guide sleeve assembly to move away from the fixed seat 110.

[0045] The above-mentioned guide device 100 is fixedly connected to the multi-axis device by fixing the fixed seat 110 to realize the fixed connection between the entire guide device 100 and the multi-axis device, and an avoidance channel 111 for the drill bit 200 to pass through is set on the fixed seat 110 to avoid the drill bit 200 on the multi-axis device; the guide sleeve assembly 120 is slidably connected to the fixed seat 110 so that the guide sleeve assembly 120 can move relative to the fixed seat 110 along with the movement of the drill bit 200, thereby providing necessary space for the movement of the drill bit 200. By setting a positioning surface 1216 on the guide sleeve assembly 120, when drilling a hole 200, the multi-axis device drives the drill bit 200 and the guide device to move toward the workpiece to be processed, and the positioning surface on the guide sleeve assembly 120 first contacts the plane where the hole of the workpiece to be processed is located, and at this time, the positioning surface positions the guide sleeve assembly 120. By setting a positioning through hole 1221 on the guide sleeve assembly 120, the drill bit 200 is positioned and constrained, so that the drill bit 200 will not be offset, thereby ensuring the center position of the drill hole on the workpiece to be processed. By setting an elastic member 130 between the guide sleeve assembly 120 and the fixed seat 110, the elastic member 130 provides elastic force for the guide sleeve assembly 120 to move away from the fixed seat 110. During the drilling process, the elastic member 130 is compressed, and the fixed seat 110 can move toward the guide sleeve assembly 120; when the drilling is completed, the guide sleeve assembly 120 moves away from the fixed seat 110 under the elastic force of the elastic member 130. Since the elastic member has elastic force, the guide sleeve assembly 120 can overcome the force of the elastic member 130 and move relative to the fixed seat 110, thereby ensuring that the drill bit 200 can move normally. Through the above structure, while ensuring normal drilling, the drill bit 200 can be positioned and constrained to ensure that the drill bit 200 will not deviate, thereby ensuring the center position of the drilling hole and further ensuring the processing quality of the parts.

[0046] It can be understood that, in this embodiment, as shown in FIG1 , the elastic member 130 is a spring, and the two ends of the spring respectively abut against the fixed seat 110 and the guide sleeve assembly 120. As shown in FIG1 and FIG4 , the fixed seat 110 is a cylindrical structure as a whole, and the through hole along the axial direction of the cylindrical structure is the avoidance channel 111. The end surface of the fixed seat 110 facing away from the guide sleeve assembly 120 abuts against the multi-axis device and is fixed to the multi-axis device.

[0047] As shown in Figures 1, 5 and 6, in one embodiment, the guide sleeve assembly 120 includes a movable sleeve 121 and a guide sleeve 122, the movable sleeve 121 is configured with a accommodating cavity 1211 with an opening at one end, the elastic member 130 is arranged in the accommodating cavity 1211, the end of the fixed seat 110 away from the multi-axis device is inserted in the accommodating cavity 1211, and the end of the movable sleeve 121 away from the fixed seat 110 is provided with a mounting hole 1212 connected to the accommodating cavity 1211; the guide sleeve 122 is fixed in the mounting hole 1212, and a positioning through hole 1221 is configured on the guide sleeve 122, and the positioning through hole 1221 is connected to the accommodating cavity 1211 and the avoidance channel 111.

[0048] By providing an accommodating cavity 1211 at one end of the movable sleeve 121 to accommodate the elastic member 130, the movable sleeve 121 can also be sleeved on the fixed seat 110 to achieve relative movement of the movable sleeve 121 relative to the fixed seat 110. By providing a mounting hole 1212 on the movable sleeve 121, the guide sleeve 122 is fixed to the fixed seat 110. By providing a positioning through hole 1221 on the guide sleeve 122, and connecting the positioning through hole 1221 with the avoidance channel 111 and the accommodating cavity 1211, the drill bit 200 can pass through the avoidance channel 111 and the accommodating cavity 1211 and pass through the positioning through hole 1221. In the present technical solution, the guide sleeve assembly 120 is configured such that the guide sleeve 122 is provided with a positioning through hole 1221, and the guide sleeve 122 is fixedly connected to the movable sleeve 121, so that the guide sleeve 122 and the movable sleeve 121 can be made of two different materials. For example, the guide sleeve 122 can be made of a wear-resistant material to increase the service life of the guide sleeve assembly 120. The movable sleeve 121 can be made of ordinary materials, which is easy to process and can reduce production costs.

[0049] It is understood that the end surface of the movable sleeve 121 away from the fixed seat 110 is the positioning surface 1216 described above.

[0050] The movable sleeve 121 is generally of a cylindrical structure, and the accommodating cavity 1211 is a cylindrical cavity. The opening of the accommodating cavity 1211 faces the fixed seat 110, so that the elastic member 130 can be placed in the accommodating cavity 1211 from the opening, and the end of the fixed seat 110 can extend from the opening into the accommodating cavity 1211. One end of the elastic member 130 is pressed against the end surface of the fixed seat 110, and the other end of the elastic member 130 is pressed against the bottom surface of the accommodating cavity 1211. It should be noted that the mounting hole 1212 on the movable sleeve 121 is connected to the accommodating cavity 1211, and the extension direction of the mounting hole 1212 is consistent with the axis of the movable sleeve 121 and the accommodating cavity 1211. In this way, the accommodating cavity 1211 is connected with the mounting hole 1212 and the positioning through hole 1221 on the guide sleeve 122 , so that the drill bit 200 can pass through the avoidance channel 111 , the accommodating cavity 1211 and the positioning through hole 1221 .

[0051] It is understandable that the mounting hole 1212 may extend from one end of the movable sleeve 121 away from the fixing seat 110 to communicate with the accommodating cavity 1211. The height of the guide sleeve 122 may be the same as the depth of the mounting hole 1212, or may be less than the depth of the mounting hole 1212, that is, the guide sleeve 122 may fill the entire mounting hole 1212, or may fill a portion of the mounting hole 1212.

[0052] As shown in FIG. 1 and FIG. 5 to FIG. 7 , in one embodiment, a chip removal groove 1213 is provided on the movable sleeve 121 along the axial direction of the movable sleeve 121. The chip removal groove 1213 is provided between the accommodating chamber 1211 and the guide sleeve 122, and the chip removal groove 1213 passes through the radial direction of the movable sleeve 121. By providing the chip removal groove 1213 between the accommodating chamber 1211 and the guide sleeve 122, the chips generated during drilling can be discharged from the chip removal groove 1213, thereby preventing the chips from entering the accommodating chamber 1211 and causing the elastic member 130 to be stuck, so as to ensure that the movable sleeve 121 can slide smoothly relative to the fixed seat 110.

[0053] Specifically, the movable sleeve 121 is provided with a chip removal groove 1213 spaced apart from the accommodating cavity 1211, the guide sleeve 122 is fixed in the mounting hole 1212 at one end of the movable sleeve 121 away from the accommodating groove, and the accommodating cavity 1211 and the chip removal groove 1213 are connected through the mounting hole 1212 on the partition wall between the accommodating cavity 1211 and the chip removal groove 1213. It can be understood that the aperture of the mounting hole 1212 on the partition wall is larger than the aperture of the positioning through hole 1221 on the guide sleeve 122.

[0054] As shown in Fig. 1 and Fig. 5 to Fig. 7, in one embodiment, two oppositely arranged recessed portions 1214 are arranged on the outer circumferential surface of the movable sleeve 121, and the recessed portions 1214 are recessed in the direction close to the axis of the movable sleeve 121. Such an arrangement can reduce the weight of the movable sleeve 121, thereby making the entire guide device 100 lighter and more convenient to use.

[0055] As shown in Figures 6 and 7, in this embodiment, the recessed portion 1214 is a structure formed by removing a portion from the outer circumferential surface of the movable sleeve 121, the largest planes of the two recessed portions 1214 are parallel to the axis of the movable sleeve 121, and the largest planes of the two recessed portions 1214 are arranged parallel to each other.

[0056] As shown in Fig. 6 and Fig. 7, in one embodiment, a portion of the radial sidewall of the accommodating cavity 1211 is provided through. Such a configuration can further reduce the weight of the movable sleeve 121 and reduce the contact area between the fixed seat 110 and the movable sleeve 121, thereby reducing the friction between the fixed seat 110 and the movable sleeve 121.

[0057] It is understandable that when the entire recessed portion 1214 is removed, it extends to the position corresponding to the accommodating cavity 1211, so as to remove a portion of the side wall corresponding to the accommodating cavity 1211, thereby forming a through setting of a portion of the side wall of the accommodating cavity 1211 in the radial direction.

[0058] As shown in FIGS. 1 to 3 and 5, in one embodiment, the guide device 100 further includes a guide rod 140, one end of which is fixedly connected to the fixed seat 110, and the other end of which is guided and matched with the movable sleeve 121. In the present technical solution, by fixing one end of the guide rod 140 with the fixed seat 110 and the other end of which is guided and matched with the movable sleeve 121, the relative movement of the movable sleeve 121 and the fixed seat 110 is guided, thereby ensuring that the movement of the movable sleeve 121 and the fixed seat 110 can be smoother and more reliable.

[0059] Specifically, two first bosses 1215 are arranged opposite to each other along the radial direction of the movable sleeve 121 on the outer circumferential surface of the movable sleeve 121, and each first boss 1215 is provided with a guide through hole 1215a extending along the axial direction of the movable sleeve 121, and the guide rod 140 is guided and matched with the guide through hole 1215a. By arranging the first boss 1215 on the outer circumferential surface of the movable sleeve 121 and arranging the guide through hole 1215a on the first boss 1215, the guide through hole 1215a is reasonably arranged while ensuring the structural strength of the movable sleeve 121.

[0060] A limiting protrusion is provided at one end of the guide rod 140, and the other end of the guide rod 140 passes through the guide through hole 1215a and is fixedly connected to the fixing seat 110. The limiting protrusion on the guide rod 140 limits the guide rod 140 from being separated from the movable sleeve 121 from the guide through hole 1215a.

[0061] As shown in Fig. 1 and Fig. 4, further, two second bosses 112 are arranged opposite to each other on the fixing seat 110, and the second bosses 112 correspond to the first bosses 1215 one by one. The first bosses 1215 are provided with connection holes 1121, and one end of the guide rod 140 is fixed in the connection holes 1121. By providing the second bosses 112 corresponding to the first bosses 1215 on the fixing seat 110, the fixed connection between the guide rod 140 and the fixing seat 110 is achieved while ensuring the structural strength of the fixing seat 110.

[0062] It is understandable that in one embodiment, the connection hole 1121 may be a threaded hole, and a thread may be provided on the end of the guide rod 140 away from the limiting protrusion, and the guide rod 140 is threadedly connected to the connection hole 1121 to achieve a fixed connection between the guide rod 140 and the fixing seat 110. Such a configuration has a simple structure and is easy to install.

[0063] As shown in FIG. 1 and FIG. 4 , in another embodiment, the second boss 112 is further provided with a first through hole 1122, the axis of the first through hole 1122 is perpendicular to the axis of the connecting hole 1121, the guide rod 140 is provided with a second through hole, the axial direction of the second through hole is perpendicular to the axis of the guide rod 140, the first through hole 1122 and the second through hole correspond to each other, and the fastener passes through the first through hole 1122 and the second through hole to fix the guide rod 140 to the first boss 1215. In the technical solution, the above structural form is not only simple in structure, but also convenient for realizing the fixed connection between the guide rod 140 and the fixing seat 110.

[0064] By setting a first through hole 1122 on the second boss 112 and a second through hole on the guide rod 140, a fastener is passed through the first through hole 1122 and the second through hole to achieve a fixed connection between the guide rod 140 and the first boss 1215, which has the advantages of reliable fixation and easy installation.

[0065] As shown in Fig. 1 and Fig. 4, in one embodiment, two connecting lugs 113 are provided on the fixing seat 110, and a third through hole 1131 is provided on the connecting lug 113 for fasteners to pass through, so as to realize the fixed connection between the fixing seat 110 and the multi-axis device. Through the above structural form, the fixed connection between the fixing seat 110 and the multi-axis device can be realized.

[0066] With reference to FIGS. 1 to 3 , it can be understood that the working principle of the guide device 100 provided in the embodiment of the utility model is:

[0067] The fixed seat 110 of the guide device 100 is fixedly connected to the multi-axis device. When the multi-axis device moves toward the workpiece to be processed, the ends of the guide sleeve 122 and the movable sleeve 121 first contact the surface of the workpiece to be processed and adhere to it. When the multi-axis device continues to move toward the workpiece to be processed, the elastic member 130 is compressed, and the drill bit 200 starts to drill. Since the drill bit 200 is constrained by the positioning through hole 1221 on the guide sleeve 122, the drill bit 200 does not deviate, thereby ensuring the center position of the drilling hole.

[0068] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0069] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent.
