Description

Technical Field

[0001] This utility model relates to the technical field of short electric arc machine tool equipment, and in particular to a spindle support device for a short electric arc machine tool. Background Technology

[0002] Short arc machine tools are a type of special electrical discharge machining equipment, mainly used for the processing and repair of high-hardness, high-wear-resistant conductive materials. They utilize a high-energy short arc discharge group excited between the tool electrode and the workpiece to erode the conductive material, and are suitable for the efficient processing of high-temperature alloys, titanium alloys, and ultra-hard, high-strength conductive materials.

[0003] The spindles of existing vertical short arc machine tools mainly adopt rigid or ring-type mounting structures. Rigid connection structures require the fabrication of tool bodies. On the one hand, the tool body can reduce the working range of the spindle's Z-axis. On the other hand, the tool body will wobble, which can easily lead to a decrease in machining accuracy. Ring-type structures are generally used in portable, lightweight small spindles, and it is difficult to achieve insulation and fixation for large spindles. Utility Model Content

[0004] In view of this, the present invention provides a short arc machine tool spindle support device, the main purpose of which is to provide a short arc machine tool spindle support device that can save equipment space and has an insulating structure between rigid conductive materials.

[0005] To achieve the above objectives, this utility model mainly provides the following technical solutions:

[0006] This utility model embodiment provides a short-arc machine tool spindle support device, which includes:

[0007] A base having a first through hole;

[0008] The spindle is inserted into the first through hole;

[0009] An insulating support component includes a first insulating sleeve, a second insulating sleeve, an insulating bolt, and a support drag component. The first insulating sleeve is disposed between the base and the main shaft. The insulating bolt passes through the main shaft and the first insulating sleeve in sequence and is connected to the base. One end of the support drag component is connected to the base, and the other end is located on the lower part of the insulating bolt to support the insulating bolt. The second insulating sleeve is disposed between the main shaft and the support drag component.

[0010] Furthermore, the supporting towing component includes a supporting towing body and a plurality of connecting bolts. The upper part of the supporting towing body is provided with a plurality of connecting holes, and the connecting bolts pass through the connecting holes and are connected to the base.

[0011] Furthermore, the supporting towing body includes a support ring, a connecting ring, and a connecting groove.

The connecting hole is located in the upper part of the connecting groove, and the support ring is located in the lower part of the insulating bolt.

[0012] Furthermore, the second insulating sleeve includes a first insulating ring, a second insulating ring, and a third insulating ring, wherein the first insulating ring, the second insulating ring, and the third insulating ring are integrally formed, and the second insulating ring is disposed between the first insulating ring and the third insulating ring.

[0013] Furthermore, the first insulating ring is perpendicular to the second insulating ring.

[0014] Furthermore, the first insulating ring is located between the insulating bolt and the support ring, the first insulating ring has a first platform, the first platform is attached to one end face of the insulating bolt, the connecting ring and the main shaft are disposed on both sides of the second insulating ring, and the connecting ring and the base are disposed on both sides of the third insulating ring.

[0015] Furthermore, the first insulating sleeve includes a fourth insulating ring and a sleeve body, the fourth insulating ring and the sleeve body are integrally formed, the first insulating ring is located at the lower edge of the sleeve body, and the fourth insulating ring is provided with a plurality of second through holes for the insulating bolt to pass through.

[0018] This utility model provides a spindle support device for a short-arc machine tool. The base serves to mount the spindle and has a first through hole.

[0024] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0025] like Figures 1 to 5 As shown, this utility model embodiment provides a short-arc machine tool spindle support device, which includes:

[0026] Base 1, wherein the base 1 has a first through hole 11;

[0027] Main spindle 2, which is inserted into the first through hole 11;

[0028] An insulating support component includes a first insulating sleeve 31, a second insulating sleeve, an insulating bolt 33, and a support drag component. The first insulating sleeve 31 is disposed between the base 1 and the main shaft 2. The insulating bolt 33 passes through the main shaft 2 and the first insulating sleeve 31 in sequence and is connected to the base 1. One end of the support drag component is connected to the base 1, and the other end is located on the lower part of the insulating bolt 33 to support the insulating bolt 33. The second insulating sleeve is disposed between the main shaft 2 and the support drag component.

[0029] This utility model provides a support device for a short-arc machine tool spindle 2. The base 1 serves to mount the spindle 2 and has a first through hole 11. The spindle 2 is inserted into the first through hole 11. An insulating support component provides insulation and support for the connection between the base 1 and the spindle 2. The insulating support component includes a first insulating sleeve 31, a second insulating sleeve, an insulating bolt 33, and a support drag component. The first insulating sleeve 31 is disposed between the base 1 and the spindle 2. The insulating bolt 33 passes through the spindle 2 and the first insulating sleeve 31 and is connected to the base 1. One end of the support drag component is connected to the base 1, and the other end is located below the insulating bolt 33 to support it. The second insulating sleeve is disposed between the spindle 2 and the support drag component. Compared to existing technologies, the spindle 2 of existing vertical short-arc machine tools mainly adopts a rigid or ring-type mounting structure. Rigid connection structures require the fabrication of a tool body, which... While reducing the Z-axis working range of the spindle 2 can reduce tool body wobbling, leading to decreased machining accuracy, the encircling structure is generally used in portable, lightweight small spindles 2. Insulation and fixation of large spindles 2 is difficult to achieve. In this technical solution, a first insulating sleeve 31 is set between the base 1 and the spindle 2, and then the base 1, spindle 2, and first insulating sleeve 31 are connected by insulating bolts 33. The support support component supports the insulating bolts 33, preventing them from breaking under the weight of the spindle 2. Furthermore, a second insulating sleeve is set between the support support component and the spindle 2, saving space in the Z-axis direction and indirectly increasing the Z-axis travel. The support support component also suppresses the axial freedom of the spindle 2, providing support for the electrical discharge machining equipment. Simultaneously, the second insulating sleeve between the support support component and the spindle 2 prevents potential difference discharge between them, allowing for the expansion of various electrical discharge machining equipment and thus improving the applicability of the equipment.

[0030] The base 1 serves to mount the spindle 2. The base 1 utilizes existing short-arc machine tools, which typically include a power supply device 9 and a pulley 8. During operation, the short-arc machine tool receives direct current from the power supply device 9. The pulley 8 is connected to the spindle 2, and a belt drives the pulley 8 and the spindle 2 to rotate. The base 1 has a first through hole 11 into which the spindle 2 is inserted. The size of the spindle 2 can be customized as needed, and the spindle 2 is longitudinally mounted within the first through hole 11. The insulating support component provides insulation for the connection between the base 1 and the spindle 2. The structure includes a rigid structure and a supporting structure. The insulating support component includes a first insulating sleeve 31, a second insulating sleeve, an insulating bolt 33, and a support drag component. The first insulating sleeve 31 is made of high-strength PEEK insulating sleeve and is disposed between the base 1 and the main shaft 2 to achieve insulation between the main shaft 2 and the base 1. The insulating bolt 33 passes through the main shaft 2 and the first insulating sleeve 31 in sequence and is connected to the base 1. The insulating bolt 33 is made of PEEK insulating bolt 33 and is installed longitudinally. The insulating bolt 33 passes through the main shaft 2 and the first insulating sleeve 31 in sequence and is connected to the base 1. The first insulating sleeve 31 is connected to the base 1. Since the insulating bolt 33 has relatively weak tensile strength, one end of the support component is connected to the base 1, and the other end is located below the insulating bolt 33 to support it. The second insulating sleeve is disposed between the spindle 2 and the support component to prevent potential difference discharge between the support component and the spindle 2. In this technical solution, by setting the first insulating sleeve 31 between the base 1 and the spindle 2, and then connecting the base 1, spindle 2, and first insulating sleeve 31 with the insulating bolt 33, the support... The support component supports the insulating bolt 33 to prevent it from breaking under the weight of the spindle 2. Furthermore, a second insulating sleeve is installed between the support component and the spindle 2, which not only saves space in the Z-axis direction and indirectly increases the Z-axis travel, but also restricts the axial freedom of the spindle 2, providing support for the electrical discharge machining equipment. Simultaneously, the second insulating sleeve prevents potential difference discharge between the support component and the spindle 2, enabling the expansion into various electrical discharge machining equipment and thus improving the applicability of the equipment.

[0031] Furthermore, the supporting towing component includes a supporting towing body and multiple connecting bolts 342. The upper part of the supporting towing body is provided with multiple connecting holes 346, and the connecting bolts 342 pass through the connecting holes 346 and are connected to the base 1. In this embodiment, the supporting towing component is further defined. The supporting towing body is made of metal, and one end of the supporting towing body is provided with multiple connecting holes 346. The connecting bolts 342 are connected to the second threaded hole 13, passing through the connecting holes 346 and connecting to the second threaded hole 13 of the base 1. The connecting bolts 342 are connected to the second threaded hole 13 to fix the supporting towing body. Specifically, the supporting towing body includes a support ring 343, a connecting ring 344, and a connecting groove 345. The two ends of the connecting ring 344 are respectively connected to the support ring 343 and the connecting groove 345. A connecting hole 346 is provided at the upper part of the connecting groove 345, and a support ring 343 is provided at the lower part of the insulating bolt 33. The support ring 343, the connecting ring 344, and the connecting groove 345 are integrally formed. The support ring 343 is provided at the lower part of the insulating bolt 33 to support the insulating bolt 33. One end of the support ring 343 is connected to the connecting ring 344, and the connecting ring 344 is perpendicular to the support ring 343. A connecting hole 346 is provided at the upper part of the connecting groove 345.

[0032] Furthermore, the second insulating sleeve includes a first insulating ring 321, a second insulating ring 322, and a third insulating ring 323. The first insulating ring 321, the second insulating ring 322, and the third insulating ring 323 are integrally formed.

The first insulating ring 321, the second insulating ring 322, and the third insulating ring 323 are integrally formed. Specifically, the first insulating ring 321 is located between the insulating bolt 33 and the support ring 343. The first insulating ring 321 has a first platform that fits against one end face of the insulating bolt 33. The two sides of the insulating bolt 33 are the main shaft 2. Therefore, the first insulating ring 321 can prevent the main shaft 2 from contacting the support body. The connecting ring 344 and the main shaft 2 are disposed on both sides of the second insulating ring 322. The second insulating ring 322 is vertically connected to the first insulating ring 321. The second insulating ring 322 is located in the gap between the main shaft 2 and the connecting ring 344 to prevent the main shaft 2 and the support body from contacting each other. The second insulating ring 322 has a second platform. One side of the fourth insulating ring 311 is attached to the second platform. The connecting ring 344 and the base 1 are disposed on both sides of the third insulating ring 323. That is, the third insulating ring 323 is located in the gap between the connecting ring 344 and the base 1, thereby achieving the technical effect of filling the gap between the connecting ring 344 and the base 1.

[0033] Furthermore, the first insulating sleeve 31 includes a fourth insulating ring 311 and a sleeve body 312. The fourth insulating ring 311 and the sleeve body 312 are integrally formed. The first insulating ring 321 is located at the lower edge of the sleeve body 312. The fourth insulating ring 311 has multiple second through holes 313 for the insulating bolt 33 to pass through. In this embodiment, the first insulating sleeve 31 is further defined. The sleeve body 312 is located between the base 1 and the spindle 2 to separate the base 1 and the spindle 2. The fourth insulating ring 311 is vertically connected to the sleeve body 312. The fourth insulating ring 311 has multiple second through holes 313. The base 1 has multiple first threaded holes 12 and multiple second threaded holes 13. The insulating bolt 33 is connected to the first threaded hole 12. The insulating bolt 33 passes through the spindle 2 and the second through hole 313 and is connected to the first threaded hole 12 of the base 1, thereby achieving the technical effect of restricting the axial degree of freedom of the spindle 2.
