Description

Technical Field

[0001] This utility model relates to the technical field of horizontal machining centers, specifically a workpiece fixture for a horizontal machining center. Background Technology

[0002] A horizontal machining center is a high-precision, high-efficiency CNC machine tool. Its spindle axis is parallel to the worktable plane and is horizontal. It is usually equipped with a rotatable worktable, such as an indexing table or a CNC rotary table. It is suitable for machining parts with large volume, complex structure and high precision requirements. In the machining process of a horizontal machining center, the workpiece fixture plays a crucial role. The workpiece fixture can accurately fix the workpiece in the position required for machining, which helps to avoid the displacement or vibration of the workpiece under the action of cutting force. However, this type of equipment still has some defects.

[0003] Since the workpiece fixture of a horizontal machining center can only process the surface in a single direction after the workpiece is clamped, if it is necessary to process other processing points on the outer periphery of the product, the workpiece needs to be disassembled and repositioned multiple times, resulting in low processing efficiency and significant accumulation of positioning errors. It cannot achieve continuous processing in multiple positions and no longer meets people's needs. Therefore, we propose a new type of workpiece fixture for horizontal machining centers to solve the above-mentioned defects and achieve the advantages of high-precision continuous processing. Utility Model Content

[0004] The purpose of this utility model is to provide a workpiece fixture for a horizontal machining center to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a workpiece fixture for a horizontal machining center, including a fixture disk, and further comprising...

[0006] A front adjustment seat is connected to one end of the clamping plate. A servo motor, a worm gear, and a worm wheel are sequentially mounted on the front adjustment seat. An encoder is mounted on the output end of the servo motor.

[0007] One end of the front adjustment seat is movably connected to the rear adjustment seat, a controller is installed on one side of the rear adjustment seat, a reserved slide groove is provided on the rear adjustment seat, and a telescopic cylinder is movably connected between the reserved slide groove and the front adjustment seat.

[0008] A vertical drive housing is installed at one end of the rear adjustment seat. Drive arms are provided at the bottom of both sides of the vertical drive housing, and the bottom of the drive arms is connected to a horizontal drive housing.

[0009] A self-locking motor, a lead screw, and a nut seat are sequentially installed on both the horizontal and vertical drive housings. Guide rails are provided inside both the horizontal and vertical drive housings, and laser rangefinders that match the guide rails are installed on the nut seats.

[0010] Furthermore, the servo motor is fixed to the bottom of the front adjustment seat, the worm gear is connected to the output end of the servo motor, and the worm wheel is meshed with one side of the worm gear.

[0011] Furthermore, bearings are respectively provided between the worm and the inner wall of the front adjusting seat.

[0012] Furthermore, the worm gear and the clamping disc are assembled into a disassembly and installation structure by screws, and the horizontal center line of the clamping disc and the horizontal center line of the worm gear are on the same straight line.

[0013] Furthermore, the horizontal drive housing is provided with two parts, the lead screw is connected to the output end of the self-locking motor, and the nut seat is screwed onto the lead screw.

[0014] Furthermore, a sliding connection is formed between the nut seat and the guide rail.

[0015] Furthermore, the fixture disk is uniformly fixed with electrically operated telescopic rods arranged at equal angles inside, and the output end of the electrically operated telescopic rods is provided with a clamping device to facilitate the positioning and fixing of the product to be processed.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] The workpiece fixture of this horizontal machining center, equipped with encoders, optimizes its performance. Firstly, after the product, fixed inside the fixture disk, completes its initial processing, the controller, based on preset trajectory data for the product, starts a servo motor. This, combined with the transmission of a worm gear and worm wheel, drives the fixture disk to rotate, sequentially rotating the product's outer periphery to the bottom. The encoder converts the mechanical rotation angle of the servo motor's output shaft into an electrical signal, providing precise position feedback to the controller. Based on this feedback, the controller dynamically adjusts the drive parameters, ultimately achieving high-precision control of the servo motor's output shaft rotation angle. This facilitates intelligent adjustment of the product's outer periphery within the fixture disk, aligning it to the bottom for processing. Secondly, the controller activates a telescopic cylinder, extending its output rod. This, combined with the cylinder's movement and rotation on the pre-reserved groove on the rear adjusting seat and the rotation of the output rod on the front adjusting seat, allows the front adjusting seat and fixture disk to rotate 90 degrees to the top. At this point, the product on the fixture disk rotates via the front adjusting seat... When rotated to the bottom position, the surface is flipped to a vertically upward position. At this point, the machining position is aligned with the horizontal machining head of the horizontal machining center, facilitating the machining of the product's outer perimeter. Simultaneously, the controller activates the self-locking motors on the horizontal and vertical drive housings, coordinating with the transmission action of the lead screw and nut seat. This drives the vertical drive housing to automatically adjust its horizontal lateral position along the horizontal drive housing, and also automatically moves the rear adjustment seat vertically on the vertical drive housing. Furthermore, a laser rangefinder sensor mounted on the nut seat monitors the relative displacement of the nut seat and guide rail on the horizontal and vertical drive housings in real time. This real-time displacement data is fed back to the controller, enabling intelligent control of the product's outer perimeter machining position on the fixture plate to align with and contact the horizontal machining head of the horizontal machining center for machining operations. This allows the device to continuously adjust the product so that different machining positions on its outer wall sequentially align with the horizontal machining head of the horizontal machining center, and through the sensor feedback structure, it achieves precise control of the product's machining position, improving machining accuracy.

[0028] Front adjustment seat 2 is connected to one end of clamping plate 1. Servo motor 11, worm gear 10 and worm wheel 12 are sequentially installed on front adjustment seat 2. Encoder 13 is installed on the output end of servo motor 11.

[0029] A rear adjustment seat 3 is movably connected to one end of the front adjustment seat 2, and a controller 4 is installed on one side of the rear adjustment seat 3;

[0030] The servo motor 11 is fixed to the bottom of the front adjustment seat 2, the worm gear 10 is connected to the output end of the servo motor 11, and the worm wheel 12 is meshed with one side of the worm gear 10.

[0031] Bearings are provided between the worm 10 and the worm wheel 12 and the inner wall of the front adjusting seat 2, respectively;

[0032] The worm gear 12 and the clamping disc 1 are connected by screws to form a disassembly and installation structure. The horizontal center line of the clamping disc 1 and the horizontal center line of the worm gear 12 are on the same straight line.

[0033] In use, after the product fixed inside the fixture disk 1 completes its first processing in the horizontal machining center, the controller 4 controls the servo motor 11 to start based on the preset trajectory data for the product to be processed. With the transmission action of the worm gear 10 and worm wheel 12, the fixture disk 1 is driven to rotate, so that the outer periphery of the product to be processed rotates to the bottom in sequence. The encoder 13 converts the mechanical rotation angle of the output shaft of the servo motor 11 into an electrical signal, providing the controller 4 with precise position feedback. The controller 4 dynamically adjusts the drive parameters based on the feedback signal, and finally achieves high-precision control of the rotation angle of the output shaft of the servo motor 11. This facilitates intelligent control of the outer periphery of the product inside the fixture disk 1 to be processed, aligning it to the bottom for processing.

[0034] The rear adjustment seat 3 is provided with a reserved slide groove 9, and a telescopic cylinder 6 is movably connected between the reserved slide groove 9 and the front adjustment seat 2.

[0035] A vertical drive housing 5 is installed at one end of the rear adjustment seat 3. Drive arms 8 are provided at the bottom of both sides of the vertical drive housing 5, and the bottom of the drive arms 8 is connected to a horizontal drive housing 7.

[0036] In use, the controller 4 controls the telescopic cylinder 6 to start, which drives the output rod of the telescopic cylinder 6 to extend. In conjunction with the movement and flipping of the telescopic cylinder 6 on the reserved slide groove 9 on the rear adjustment seat 3 and the flipping of the output rod of the telescopic cylinder 6 on the front adjustment seat 2, the front adjustment seat 2 and the fixture plate 1 can be flipped 90 degrees to the top. At this time, the product on the fixture plate 1 will be flipped to the vertically upward position after being rotated to the bottom position by the front adjustment seat 2. At this time, the processing position will be aligned with the horizontal processing head of the horizontal machining center, which is convenient for processing the outer periphery of the product.

[0037] A self-locking motor 18, a lead screw 17, and a nut seat 14 are sequentially installed on both the horizontal drive housing 7 and the vertical drive housing 5. Guide rails 15 are provided inside both the horizontal drive housing 7 and the vertical drive housing 5. A laser rangefinder sensor 16 that matches the guide rails 15 is installed on the nut seat 14.

[0038] Two horizontal drive housings 7 are provided, with lead screws 17 connected to the output end of self-locking motors 18 and nut seats 14 screwed onto lead screws 17.

[0039] A sliding connection is formed between the nut seat 14 and the guide rail 15;

[0040] In use, the controller 4 controls the self-locking motors 18 on the horizontal drive housing 7 and the vertical drive housing 5 to start, and with the transmission action of the lead screw 17 and the nut seat 14, the vertical drive housing 5 is driven to move and adjust automatically in the horizontal direction along the horizontal drive housing 7. It also drives the rear adjustment seat 3 to move automatically in the vertical direction on the vertical drive housing 5. With the help of the laser range sensor 16 installed on the nut seat 14, the relative displacement of the nut seat 14 and the guide rail 15 on the horizontal drive housing 7 and the vertical drive housing 5 can be monitored in real time. The displacement data is then fed back to the controller 4 in real time, which facilitates its intelligent control of the product's outer peripheral processing position on the fixture plate 1 to align with and contact the horizontal processing head of the horizontal machining center for processing.

[0041] The clamping disc 1 has electric telescopic rods 20 arranged at equal angles evenly fixed inside. The output end of the electric telescopic rod 20 is provided with a clamping fastener 19 to facilitate the positioning and fixing of the product to be processed.

[0042] The working principle of this utility model is as follows: First, the user fixes the horizontal drive housing 7 on the operating table of the horizontal machining center using screws. Then, the product to be processed is clamped into the fixture disk 1. By activating the three equally angled electric telescopic rods 20, the clamping fasteners 19 at their output ends are driven to position and fix the product to be processed. In actual operation, after the product fixed inside the fixture disk 1 completes its first processing in the horizontal machining center, the controller 4 controls the servo motor 11 to start according to the preset trajectory data for the product to be processed. With the transmission action of the worm gear 10 and worm wheel 12, the fixture disk 1 rotates, causing the outer periphery of the product to be processed. The positions are rotated sequentially to the bottom, and the encoder 13 converts the mechanical rotation angle of the output shaft of the servo motor 11 into an electrical signal, providing precise position feedback to the controller 4. The controller 4 dynamically adjusts the drive parameters based on the feedback signal, ultimately achieving high-precision control of the rotation angle of the output shaft of the servo motor 11. This facilitates intelligent control of the outer periphery of the product inside the fixture disk 1 to be processed, aligning it to the bottom for processing. Furthermore, the controller 4 controls the telescopic cylinder 6 to start, causing the output rod of the telescopic cylinder 6 to extend. This, combined with the movement and flipping of the telescopic cylinder 6 on the reserved slide groove 9 on the rear adjusting seat 3 and the flipping of the output rod of the telescopic cylinder 6 on the front adjusting seat 2, allows for the movement and flipping of the telescopic cylinder 6 on the reserved slide groove 9 on the rear adjusting seat 3. By rotating the front adjusting seat 2 and the clamping plate 1, the product on the clamping plate 1, which has been rotated to its lowest position via the front adjusting seat 2, will be flipped to a vertically upward position. This machining position will then align with the horizontal machining head of the horizontal machining center, facilitating the machining of the product's outer perimeter. Simultaneously, the controller 4 activates the self-locking motors 18 on the horizontal drive housing 7 and the vertical drive housing 5. These motors, in conjunction with the lead screw 17 and the nut seat 14, drive the vertical drive housing 5 to automatically move horizontally along the horizontal drive housing 7. This also drives the rear adjusting seat 3 to move vertically along the vertical drive housing 5. The automated movement, combined with the laser rangefinder 16 installed on the nut seat 14, can monitor the relative displacement of the nut seat 14 and the guide rail 15 on the horizontal drive housing 7 and the vertical drive housing 5 in real time. The real-time displacement data is then fed back to the controller 4, which can intelligently control the product's outer peripheral processing position on the fixture plate 1 to align with and contact the horizontal processing head of the horizontal machining center for processing. This allows the device to continuously adjust the product so that different processing positions on its outer wall are sequentially aligned with the horizontal processing head of the horizontal machining center. Furthermore, through the sensor feedback structure, it can achieve precise control of the product's processing position, thus improving processing accuracy.
