Description

Technical Field

[0001] The utility model relates to the technical field of lathe production auxiliary devices, in particular to a lathe spindle clutch mechanism. Background Technique

[0002] The lathe clutch mechanism is a mechanism that controls the movement of the spindle by connecting and disconnecting the transmission between the power source and the spindle. It utilizes the action of friction to achieve the process of connection and disconnection, thereby realizing the rotation and stop rotation of the lathe spindle.

[0003] Since the clutch mechanism realizes control through the action of friction, the loss of the components mainly used for frictional contact on it will increase greatly. Therefore, it is necessary to frequently maintain the clutch mechanism. However, for the existing clutch mechanisms currently, during maintenance, no matter which component is maintained, the entire clutch mechanism needs to be disassembled for maintenance and replacement, and it is not possible to perform separate maintenance or replacement only for the component with the most loss, which is very troublesome.

[0022] The technical solution of the present utility model will be described in detail below with reference to the drawings and embodiments.

[0023] Please refer to Figures 1 to 4 As shown, an embodiment of the present application provides a lathe spindle clutch mechanism, including a spindle box 100, a transmission shaft mechanism 101 and a spindle 102 rotatably arranged on the spindle box 100. It is characterized in that it further includes a stop ring 1 sleeved on the transmission shaft mechanism 101, and a plurality of stop members 2 rotatably arranged on the stop ring 1. A driving mechanism 3 for driving the stop ring 1 to move so that the stop members 2 press against the transmission shaft mechanism 101 is further provided on the spindle box 100. The upper and lower ends of the stop ring 1 are respectively hinged to the driving mechanism 3 and the spindle box 100. A disassembly and assembly mechanism 4 for disassembling and assembling the stop members 2 is further provided on the stop ring 1.

[0024] By providing a disassembly and assembly mechanism 4 on the stop ring 1, the stop members 2 can be installed on or disassembled from the stop ring 1 through the disassembly and assembly mechanism 4. During maintenance and replacement, only the most worn stop members 2 can be separately maintained and replaced, without disassembling the entire clutch mechanism, which is practical and convenient.

[0025] Working principle of the lathe spindle clutch mechanism: When it is necessary to brake the rotation of the spindle 102, the driving mechanism 3 is started, and the stop ring 1 is pushed to move away from the spindle 102, driving the stop members 2 to move and press against the transmission shaft mechanism 101. Through the action of friction, the transmission shaft mechanism 101 stops rotating and disconnects the transmission with the spindle 102, so that the spindle 102 loses the power source and slowly stops rotating, completing the braking of the spindle 102.

[0026] In this embodiment, the working principle of the above clutch mechanism is a common prior art in the field and will not be described in detail here.

[0027] Further, the stop ring 1 includes a lower stop ring 11 hinged to the main spindle box 100 and an upper stop ring 12 hinged to the drive mechanism 3. The stop member 2 is disposed between the lower stop ring 11 and the upper stop ring 12, and the lower stop ring 11 and the upper stop ring 12 are connected and fixed or separated by the disassembly and assembly mechanism 4.

[0028] Specifically, the upper stop ring 12 includes a hinge post 121 hinged to the output end of the drive mechanism 3, and a left half ring 122 and a right half ring 123 symmetrically hinged to the lower end of the hinge post 121. The left half ring 122 and the right half ring 123 are respectively connected to the lower stop ring 11 through the disassembly and assembly mechanism 4 to form the stop ring 1.

[0029] During installation, the left half ring 122 and the right half ring 123 are respectively rotated outward to separate them from the lower stop ring 11. Then, the stop member 2 is respectively installed at both ends of the lower stop ring 11. Next, the left half ring 122 and the right half ring 123 are respectively rotated in the opposite direction until they are connected to both ends of the lower stop ring 11, so as to clamp the stop member 2 between the upper stop ring 12 and the lower stop ring 11. Finally, the position relationship between the upper stop ring 12 and the lower stop ring 11 is locked through the disassembly and assembly mechanism 4. During disassembly, the reverse operation is performed. When maintaining or replacing the stop member 2, the stop member 2 can be directly disassembled from the stop ring 1 without disassembling the entire clutch mechanism, which is practical and convenient.

[0030] Specifically, mounting grooves 13 for mounting the stop member 2 are respectively formed on opposite sides of the lower stop ring 11 and the upper stop ring 12.

[0031] Further, the disassembly and assembly mechanism 4 includes a first locking protrusion 41 disposed on the lower stop ring 11, a second locking protrusion 42 disposed on the upper stop ring 12 and correspondingly arranged with the first locking protrusion 41, and a locking bolt 43 for locking the relative position between the first locking protrusion 41 and the second locking protrusion 42.

[0032] During disassembly, only need to loosen the locking bolt 43, and then pull the locking bolt 43 out of the first locking protrusion 41 and the second locking protrusion 42 to complete unlocking. During locking, align the first locking protrusion 41 and the second locking protrusion 42, then pass the locking bolt 43 through the first locking protrusion 41 and the second locking protrusion 42 respectively and tighten it to complete locking, which is practical and convenient.

[0033] Specifically, a hinge platform 10 is further installed at the lower end of the main spindle box 100, and a hinge portion 110 for hinging with the hinge platform 10 protrudes from the lower end of the lower stop ring 11.

[0034] Further, the driving mechanism 3 includes a mounting seat 31 provided on the main spindle box 100, and a telescopic driver 32 hinged to the mounting seat 31.

[0035] The telescopic driver 32 is activated to drive the stop ring 1 to move, thereby driving the stop member 2 to move and press against the transmission shaft mechanism 101. Through the action of friction, the transmission shaft mechanism 101 stops rotating and disconnects the transmission with the main shaft 102, so that the main shaft 102 loses the power source and slowly stops rotating, completing the braking of the main shaft 102.

[0036] Specifically, the telescopic driver 32 includes one of an electric cylinder or an electric telescopic rod.

[0037] Further, the number of the stop members 2 is two, and they are symmetrically arranged on the stop ring 1, making the friction force more uniform respectively.

[0038] Further, the stop member 2 includes a connecting rod 21 rotatably connected to the stop ring 1, and a pressing portion 22 provided at one end of the connecting rod 21 close to the transmission shaft mechanism 101.

[0039] The above are only the embodiments of the present invention, and do not limit the patent scope of the present invention. Any equivalent structure made by using the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present invention.
