Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please refer to the following: Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 as well as Figure 6 ,in, Figure 1 A schematic diagram of a preferred embodiment of the horizontal machining center tool holder provided by this utility model; Figure 2 for Figure 1 The diagram shows the structure of the rotating disk.

[0023] In the specific implementation process, such as Figure 1-2As shown, this utility model provides a horizontal machining center tool holder including a support 1. A rotating component is fixedly connected to one side of the support 1, and a fixed seat 6 is fixedly connected to one side of the rotating component. A clamping component is provided on the top of the fixed seat 6, and a locking component is fixedly connected to the top of the clamping component. The rotating component includes a rotary motor 2 and an arc-shaped turntable. One side of the support 1 is fixedly connected to one end of the rotary motor 2, and the output end of the rotary motor 2 is fixedly connected to one side of the arc-shaped turntable. The arc-shaped turntable includes a rotating disk 5. A mounting flange is fixedly connected to one side of the rotating disk 5, and the mounting flange is fixedly connected to the output end of the rotary motor 2. The rotating disk 5 has multiple through holes arranged circumferentially. A tool fixing seat 6 for coaxial and detachable installation of tools is provided in the through holes. The tool fixing seat 6 has an inner diameter that is coaxial with and communicates with the through holes and allows the main body of the tool to extend out. The rotating disk 5 is equipped with a tool setter, which is located on the same side of the rotating disk 5 as the tool holder. The central tool setting axis of the tool setter and the central axis of the tool fixing seat 6 are arranged on the same circumference. The support 1 is equipped with a protective cover 4. The protective cover 4 has a clearance opening on the side facing the support 1 for the power output part of the rotating component to extend into. A clearance gap is reserved between the outer peripheral wall of the rotating disk 5 and the inner wall of the protective cover 4. The protective cover 4 has windows on its periphery. Under the drive of the rotating motor 2, the rotating disk 5 can be completely stored in the protective cover 4 or partially exposed outside the protective cover 4 through the windows. A baffle 3 is installed on the rotating disk 5. The length of the baffle 3 is less than the diameter of the rotating disk 5. When the rotating disk 5 is completely stored in the protective cover 4, the baffle 3 is used to block the windows. A photoelectric sensor is provided on the inner wall of the protective cover 4. A touch plate for triggering the photoelectric sensor is provided on the rotating disk 5.

[0024] It should be noted that the above-mentioned horizontal machining center tool holder (support 1, rotary motor 2, baffle 3, protective cover 4, rotating disk 5, and fixed base 6) is a rotary tool magazine and horizontal machining center (support, rotary motor 2, baffle, protective cover, arc-shaped turntable, and fixed base) disclosed in the prior art with CN219787551U. In this device, when changing tools, the arc-shaped turntable rotates at a set angle under the drive of the rotary motor 2, so that the empty tool holder is coaxially aligned with the electric spindle module. The electric spindle module moves closer to the tool holder along the Z-axis direction. The main body of the tool passes through the inner cavity of the tool holder, and the end face of the tool holder is attracted to the magnetic suction component. At this time, the electric spindle module is used to fix the tool clamping workpiece release tool. The electric spindle module moves away from the tool holder. Under the magnetic force of the magnetic suction component, the tool is transferred from the electric spindle module to the tool holder. Subsequently, the arc-shaped turntable rotates again by a set angle under the drive of rotary motor 2, aligning the tool holder with the electric spindle module coaxially. The electric spindle module moves closer to the tool holder along the Z-axis, and the tool shank enters the workpiece clamping compartment of the electric spindle module. The workpiece clamps the tool, and the electric spindle module moves away from the tool holder, overcoming the magnetic force of the magnetic attraction component, thus transferring the tool from the tool holder to the electric spindle module. After the tool change, tool setting begins. The arc-shaped turntable rotates by a set angle under the drive of rotary motor 2, aligning the tool setting device... The central tool setting axis is aligned coaxially with the electric spindle module after tool replacement, and tool setting begins. After tool setting is completed, the arc-shaped turntable returns to the zero position under the drive of the rotary motor 2, and the arc-shaped turntable is completely stored in the protective cover, providing clearance for the subsequent normal operation of the electric spindle module. The working principle and operation mode of each mechanism in this device are the same as those of a rotary tool magazine for machining center and a horizontal machining center disclosed herein, which allows the fixed seat and tool on the arc-shaped turntable to be accurately aligned and installed through the output end of the rotary motor 2.

[0025] In the specific implementation process, refer to Figure 3-6As shown, this utility model provides a horizontal machining center tool holder. The clamping assembly includes a sliding rod 7, a limiting rod 8, a placement platform 9, a slide groove 10, a first spring 11, a clamping plate 12, and a slider 13. The bottom of the inner wall of the fixed base 6 is fixedly connected to the outer wall of the placement platform 9. The inner wall of the placement platform 9 has a slide groove 10. One end of the inner wall of the slide groove 10 is fixedly connected to one end of the first spring 11, and the other end of the first spring 11 is fixedly connected to one side of the bottom of the slider 13. The bottom outer wall of the slider 13 is slidably connected to the inner wall of the slide groove 10. The top of 13 is fixedly connected to the bottom of the clamping plate 12. The outer wall of one end of the clamping plate 12 is slidably connected to one end of the limiting rod 8. The top of the limiting rod 8 is fixedly connected to the bottom of the sliding rod 7. The bottom of the sliding rod 7 is rotatably connected to the inner wall of the rotating groove opened at the top of the fixed seat 6. The top of the sliding rod 7 is fixedly connected to the bottom of the mounting column 15. The mounting column 15 is located at the top of the limiting hole. Multiple sliding rods 7, limiting rods 8, placement platform 9, sliding groove 10, spring 11, clamping plate 12 and slider 13 are equidistantly arranged on the inner wall of the fixed seat 6.

[0026] The locking assembly includes a throttle 14, a mounting post 15, a pressing post 16, a second spring 17, and a limiting post 18. The top of the sliding rod 7 is fixedly connected to the bottom of the mounting post 15. The inner wall of the mounting post 15 is slidably connected to the outer wall of the pressing post 16. The top of the pressing post 16 is fixedly connected to the bottom of the throttle 14. An arc-shaped groove is provided on the outer wall of the mounting post 15. One end of the limiting post 18 is fixedly connected to the outer wall of the pressing post 16. The other end of the limiting post 18 passes through the outer wall of the mounting post 15. The outer wall of the limiting post 18 is slidably connected to the inner wall of the arc-shaped groove. A limiting hole is provided at the top of the sliding rod 7. The limiting hole passes through to the top of the fixed seat 6. The bottom outer wall of the pressing post 16 is slidably connected to the outer wall of the limiting hole. The bottom of the mounting post 15 is fixedly connected to the top of the second spring 17. The inner wall of the second spring 17 is fixedly connected to the outer wall of the pressing post 16.

[0027] It should be noted that multiple clamping components are circumferentially distributed on the inner wall of the fixed base 6. When the sliding rod 7 moves circumferentially, it drives the limiting rod 8 to push the clamping plate 12 to slide centripetally along the slide groove 10. Under the action of the first spring 11, the clamping plate 12 has a tendency to return to its original position outward. The tool is clamped between multiple clamping plates 12, forming a uniform clamping force. The throttle 14 is connected to the pressing column 16. By rotating, it can be inserted into or withdrawn from the limiting hole. The pressing column 16 moves downward to restore the return force of the second spring 17. The limiting column 18 slides in the arc-shaped slide groove to realize the switching of the locking position. When the limiting column 18 rotates to the maximum position of the arc-shaped slide groove, the locking position is adjusted accordingly. When the device is at its lowest position, it engages with the limiting hole to lock. Reversing the operation unlocks the device and releases the clamp. The locking component controls the locking and releasing of the clamping state by rotating the handle 14. It has a self-locking function to prevent the clamp from loosening during operation. The sliding rod 7 is both part of the clamping component and the load-bearing structure of the locking component. Rotating the handle 14 locks the device. Rotating the sliding rod 7 causes the limiting rod 8 to press the clamping plate 12 and the first spring 11 to retract towards the inner wall to achieve clamping. Conversely, rotating the sliding rod releases the clamp. The contact surface between the clamping plate 12 and the limiting rod 8 is inclined, and the contact surface between the clamping plate 12 and the fixture is arc-shaped.

[0028] The working principle of this utility model is as follows: Multiple clamping components are circumferentially and equidistantly arranged on the inner wall of the fixed base 6. Each clamping component includes a sliding rod 7, a limiting rod 8, a placement platform 9, a sliding groove 10, a first spring 11, a clamping plate 12, and a slider 13. All clamping plates 12 are in an outwardly open state under the action of the first spring 11, the throttle 14 is in the initial position, the limiting post 18 is not inserted into the limiting hole, and the clamping component is in a released state. The tool to be clamped is placed stably in the center of the placement platform 9. At this time, the clamping plate 12 is in a loose state, which facilitates the insertion of the tool. The tool should be located in the clamping space formed between the multiple clamping plates 12. The sliding rod 7 rotates along the outer wall of the fixed base 6. The sliding rod 7 drives the limiting rod 8 to rotate. The limiting rod 8 pushes the clamping plate 12 to slide inward. The clamping plate 12 slides in the sliding groove 10 through the slider 13. When spring 11 is compressed, multiple clamping plates 12 move synchronously towards the center, stably clamping the tool. The tool is evenly clamped between the clamping plates 12. Rotating the handle 14 downwards causes the downward pressing column 16 connected to it to move together. The limiting column 18 moves downwards with the downward pressing column 16 and slides along the arc-shaped groove to the lowest point, so that the downward pressing column 16 is engaged in the limiting hole. After releasing the pressure from the hand, spring 17 pushes the downward pressing column 16 to return to its original position, so that the downward pressing column 16 is always located in the inner wall of the limiting hole. Reverse operation: rotating the handle 14 causes the downward pressing column 16 to disengage from the limiting hole. The sliding rod 7 rotates in the opposite direction, and the limiting rod 8 provides space for the clamping plate 12 to return to its original position. Spring 11 pushes the slider 13 and the clamping plate 12 back to their initial position. The clamping plate 12 is completely released, and the tool can be easily removed, completing one clamping cycle.

[0029] This horizontal machining center tool holder has the following advantages: Automatic reset of the clamping plate 12 is achieved using spring 11, reducing manual intervention; the insertion and release of the clamping state is achieved by controlling the insertion and release of the pressure column 16 through the throttle 14, making operation simple and intuitive; multiple clamping components are equidistantly arranged on the inner circumference of the fixed base 6, ensuring that the clamping force is evenly distributed around the tool; all clamping plates 12 are linked by the sliding rod 7 and the limit rod 8 to achieve synchronous centripetal or centrifugal movement, effectively preventing tool displacement or damage due to uneven clamping; during clamping, mechanical locking is achieved by inserting the pressure column 16 into the limit hole, ensuring that the clamping state will not be accidentally released due to external force or vibration; spring reset ensures that even if power is lost or power fails, the clamping components can maintain a certain clamping force, improving safety.

[0030] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0031] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model.
