Technical Field
[0001] This utility model relates to the field of metal processing technology, specifically to a brake locking device and a machine tool. Background Technology
[0002] Machine tools are typically used for metal processing. During the processing, in order to adjust the contact position between the metal workpiece and the cutting tool in all directions, it is usually necessary to use a spindle to control the rotation of the metal workpiece. When the cutting tool is processing, it will generate pressure when it contacts the metal workpiece. In order to prevent the spindle from rotating, a brake locking structure is needed to restrict the spindle and prevent the spindle from rotating and affecting the processing efficiency.
[0003] In existing technologies, the current brake locking structure only uses a hydraulic piston for clamping. This single braking method reduces the braking effect and makes the piston brake disc structure more prone to damage. Utility Model Content
[0004] The purpose of this invention is to provide a brake locking device and machine tool to solve the problem that the existing brake locking structure in the background art only uses a hydraulic piston for clamping, and the single braking method will reduce the braking effect and make the piston brake disc structure more susceptible to damage.
[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:
[0006] A brake locking device includes a spindle box, inside which are arranged two sets of high-efficiency braking components, which are used to improve the brake locking effect. A quick-release component is provided on the inner side of the spindle box, which is used to assist in disassembly for maintenance.
[0007] The high-efficiency braking assembly includes a brake seat, and a telescopic push rod is installed in the middle of the brake seat. The output end of the telescopic push rod is provided with positioning teeth, and two sets of pistons are provided on the inner side of the end of the brake seat. Friction plates are installed on the inner side of the pistons.
[0008] The quick-release assembly includes a positioning seat, and a drive motor is provided on the inner side of the upper and lower ends of the positioning seat. A bidirectional screw is provided at the output end of the drive motor, and a threaded sleeve is provided on the outer side of the bidirectional screw. The threaded sleeve is located on the inner side of the left end of the spindle box.
[0009] Preferably, a bearing housing is provided on the inner side of the right end of the spindle box, and a spindle clamping end is provided on the right side of the bearing housing. A splicing sleeve is installed on the left end of the bearing housing, and a gear disk is installed on the left end of the splicing sleeve. Brake discs are installed on both sides of the outer ring of the gear disk, and the brake discs are located inside the friction pads.
[0010] Preferably, four sets of welded feet are installed on the outer side of the brake seat, and the welded feet are located on the inner side of the spindle box.
[0011] Preferably, a cavity is provided on the outer side of the piston, and the cavity is located in the brake seat. An oil passage is opened at the end of the cavity, and a distributor is installed at the end of the oil passage. The distributor is located on the left side of the brake seat. A transmission pipe is installed on the outer side of the distributor, and a brake pump is installed at the end of the transmission pipe. A fixing sleeve is installed on the outer side of the brake pump, and the fixing sleeve is located inside the spindle box.
[0012] Preferably, an end plate is installed on the left side of the positioning seat, and the end plate is located on the left side of the spindle box. A spindle motor is installed on the inner side of the positioning seat, and a welding plate is installed on the output end of the spindle motor.

[0014] Compared with the prior art, the beneficial effects achieved by this utility model are:
[0015] 1. This utility model, by installing a high-efficiency braking component, can provide an installation position for the inner structure using a brake seat, and then use a telescopic push rod to control the outward extension of the positioning teeth. When the positioning teeth extend outward, they will contact and embed into the inner side of the gear disk's tooth groove. By splicing, the gear disk can be restricted. When braking, the piston, friction plate, and positioning teeth can cooperate to lock. The positioning teeth are used for complete locking rather than deceleration. The cooperation can effectively improve the braking effect.
[0016] 2. This utility model, by installing a quick-release component, addresses the issue that existing spindles and brake structures are located inside the spindle box, requiring a considerable amount of time for disassembly during maintenance. By providing a positioning seat, the internal structure can be positioned for installation. A drive motor can rotate a bidirectional screw, which in turn causes the screw sleeve to extend outward and insert into the spindle box. This insertion method allows for restraint, while retraction adjustment enables disassembly. This effectively shortens the time spent on installation and disassembly, facilitating the maintenance of the internal spindle and brake structure. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Please see Figure 1-4 The brake locking device includes a spindle box 1. The spindle box 1 is equipped with two sets of high-efficiency braking components, which are used to improve the brake locking effect.

[0026] Through the above technical solution, the brake seat 201 can provide an installation position for the inner structure, and the telescopic push rod 202 can control the outward extension of the positioning tooth 2. When the positioning tooth 2 extends outward, it will contact and embed into the inner side of the tooth groove of the gear disk 104. By splicing, the gear disk 104 can be restricted.

[0027] The above technical solution provides an installation position for the internal structure by setting a positioning seat 402. The drive motor 403 can drive the bidirectional screw 404 to rotate, and the rotation will cause the screw sleeve 405 to extend outward. After extending outward, it will be inserted into the inside of the spindle box 1. It can be restricted by combining insertion. Conversely, it can be disassembled by retracting and adjusting.

[0030] Specifically, four sets of welded feet 203 are installed on the outer side of the brake seat 201, and the welded feet 203 are located on the inner side of the spindle box 1.
[0031] Through the above technical solution, the stability of the welded foot 203 can be increased by welding.
[0032] Specifically, a cavity is provided on the outer side of the piston 306, and the cavity is located in the brake seat 201. An oil passage 305 is opened at the end of the cavity, and a distributor 304 is installed at the end of the oil passage 305. The distributor 304 is located on the left side of the brake seat 201.

A fixing sleeve 301 is installed on the outer side of the brake pump 302, and the fixing sleeve 301 is located inside the spindle box 1.
[0033] Through the above technical solution, the cavity is filled with hydraulic oil, which can push the piston 306 outward to brake under the control of the brake pump 302. The fixed sleeve 301 can restrict the brake pump 302. The brake pump 302 is connected to an external power source and can push the hydraulic oil into the oil passage 305 through the transmission pipe 303.
[0034] Specifically, an end plate 401 is installed on the left side of the positioning seat 402, and the end plate 401 is located on the left side of the spindle box 1. A spindle motor 4 is installed on the inner side of the positioning seat 402, and a welding plate 406 is installed on the output end of the spindle motor 4.

When powered on, it will drive the rotating shaft 408 to rotate. The welding plate 406 can be welded to the positioning rod 407 on the right side.

[0038] When the internal spindle motor 4 needs to be stopped during use, the brake pump 302 injects hydraulic oil into the oil passage 305 through the transmission pipe 303. The hydraulic oil pushes the piston 306 and friction plate 3 to contact the brake disc 105 for braking. At the same time, the telescopic push rod 202 pushes the positioning tooth 2 into the tooth groove of the gear disc 104 for locking. When maintenance is required, the two sets of drive motors 403 are controlled by an external controller. The rotation of the bidirectional screw 404 will retract the control screw rod 405. After retraction, it will separate from the spindle box 1. After separation, the end plate 401 and the positioning seat 402 can be removed as a whole for maintenance.
