Description

Technical Field

[0001] This utility model relates to the technical field of horizontal honing equipment, and in particular to a spindle feed mechanism for a horizontal honing machine. Background Technology

[0002] A horizontal honing machine is a mechanical device used for precision machining of holes. A search revealed Chinese patent CN216731254U, which discloses a spindle feed mechanism for a horizontal honing machine, belonging to the technical field of horizontal honing equipment. It solves the problems of poor feed stability and short service life of the honing rod feed mandrel in existing honing machines. This horizontal honing machine spindle feed mechanism includes a housing with a horizontally sliding honing spindle mounted on it. A drive device is located between the honing spindle and the housing to drive the horizontal displacement of the honing spindle. The drive device includes a drive pedal. A lever arm, perpendicular to the honing spindle, is located at the rear of the housing. The upper end of the lever arm is hinged to the housing as a fulcrum. The rear end of the honing spindle is hinged to the middle of the lever arm. A drive connecting rod is hinged to the lower end of the lever arm. A rotating component is mounted on the drive pedal, which is hinged to the housing via the rotating component. The front end of the drive connecting rod is hinged to the rotating component. This invention allows for changing the hinge fulcrum of the lever arm, facilitating adjustment of the honing spindle feed speed. It is easy to use and structurally stable.

[0003] The horizontal honing machine spindle feed mechanism in the aforementioned patent has the following shortcomings: While the feed speed of the honing spindle can be adjusted by changing the hinge fulcrum of the lever arm through the setting of the connecting shaft assembly, and the feed speed of the honing spindle can be easily fine-tuned by setting the adjustment component, it is convenient to use, has a stable structure, and a long service life. However, although the above settings can adjust the speed of the honing spindle, they cannot adjust the precise movement distance or range of the honing spindle relative to the workpiece. Therefore, a horizontal honing machine spindle feed mechanism was designed. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose a horizontal honing machine spindle feed mechanism.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A horizontal honing mill spindle feed mechanism includes a worktable. A horizontal honing mill body is fixedly connected to one side of the top of the worktable. A guardrail is fixedly connected to the top of the worktable. A honing head is located at one end of the horizontal honing mill body near the guardrail. An adjustment mechanism is located at one end of the horizontal honing mill body near the honing head. The adjustment mechanism includes a fixing block fixedly connected to one side of the horizontal honing mill body. A rectangular hole is formed in the fixing block. A limit rod is fixedly connected between the two ends of the rectangular hole. Both ends of the rectangular hole are slidably connected to... The sliders, both of which slide through the limiting rod, each have a circular hole that matches the limiting rod. A pointer is fixedly connected to the top of the side of each slider away from the honing head. The pointer, in conjunction with a scale, allows the user to accurately position the sliding plate. A screw is screwed to the bottom of the side of each slider away from the honing head. A knob is fixedly connected to the outer end of each screw. A friction plate is fixedly connected to the side of each knob near the screw. A threaded hole that matches the screw is opened at the bottom of each slider.

[0007] As a further embodiment of this utility model, the adjustment mechanism further includes a scale fixedly connected to the top of the fixed block on the side away from the honing head, and the scale is adapted to the pointer. Two U-shaped friction plates are fixedly connected to the two ends of the fixed block near the rectangular hole on the side away from the honing head, and the two U-shaped friction plates are adapted to the friction plates. By turning the knob forward and backward, the U-shaped friction plates and the friction plates are separated and contacted, so that the slider is fixed and slides. A stop block is fixedly connected to the ends of the two sliders on the side away from the honing head.

[0008] As a further embodiment of this utility model, the horizontal honing machine body has guide rods fixedly connected to both ends on the side near the honing head. The same sliding plate is slidably fitted on the circumferential surface of the two guide rods. Both ends of the sliding plate have round holes that are adapted to the guide rods. A fixing clamp is fixedly connected to the top middle of the guide rod by bolts.

[0009] As a further embodiment of this utility model, a drive mechanism is fixedly connected to the end of the horizontal honing machine body near the honing head and away from the adjustment mechanism. The drive mechanism includes a rectangular frame fixedly connected to one end of the horizontal honing machine body. A reciprocating lead screw is rotatably connected between the two ends of the inner side of the rectangular frame. A screw block is screwed onto the circumferential surface of the reciprocating lead screw, and the screw block fits into the interior of the rectangular frame. A lead screw sleeve is fixedly sleeved in the middle of the screw block, and a pin hole is provided on the inner circumferential surface of the lead screw sleeve along its radial direction. A crescent pin that cooperates with the reciprocating lead screw is provided in the pin hole.

[0010] As a further embodiment of this utility model, the driving mechanism further includes a round rod fixedly connected between the two ends of the bottom of the rectangular frame. A strip plate is slidably fitted on the circumferential surface of the round rod, and a round hole adapted to the round rod is opened at the bottom of the strip plate. The strip plate is in contact with the inner wall of the rectangular frame, and a rectangular groove is opened at the top of the strip plate. The same connecting rod is fixedly connected between the two ends of the rectangular groove, and the connecting rod slides through the bottom of the screw block. A round hole adapted to the connecting rod is opened at the bottom of the screw block. Springs are fitted at both ends of the connecting rod. A drive motor is fixedly connected to the outer end of the rectangular frame, and the output end of the drive motor is fixedly connected to one end of the reciprocating lead screw through the rectangular frame. The arrangement of the connecting rod, springs, and strip plate ensures that there is no rigid contact between the strip plate and the screw block, and the movement range of the rectangular groove is not synchronized with that of the screw block.

[0011] As a further embodiment of the present invention, the driving mechanism further includes an L-shaped rod fixedly connected to the bottom of the rectangular groove, and one end of the bottom of the L-shaped rod is fixedly connected to one end of the sliding plate.

[0012] As a further embodiment of this utility model, both of the aforementioned blocks are adapted to the end of the sliding plate that is close to it. By limiting the sliding plate with the blocks, the distance that the sliding plate can move back and forth with the workpiece is restricted.

[0013] The beneficial effects of this utility model are as follows:

[0014] This utility model employs an adjustment mechanism, a drive mechanism, and a sliding plate. The drive mechanism can reciprocate the workpiece, causing the workpiece to move relative to the honing head for processing. The adjustment mechanism allows for precise control of the workpiece's movement range, improving the workpiece's processing accuracy. This effectively solves the problems mentioned in the background technology, achieving the technical effect of precisely controlling the workpiece's movement range through the cooperation of the drive mechanism and the adjustment mechanism, improving the workpiece's processing quality, and providing convenient use and structural stability.

[0015] This invention allows for precise manual control of the sliding plate's position when the drive mechanism is not operating, enabling either a fixed sliding plate or manual control of the movement of the sliding plate and the workpiece, thus improving the equipment's practicality and convenience.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0023] Reference Figures 1-4A horizontal honing mill spindle feed mechanism includes a worktable 1. A horizontal honing mill body 2 is fixedly connected to one side of the top of the worktable 1. A guardrail 101 is fixedly connected to the top of the worktable 1. A honing head 201 is provided at one end of the horizontal honing mill body 2 near the guardrail 101. An adjustment mechanism 5 is provided at one end of the horizontal honing mill body 2 near the honing head 201. The adjustment mechanism 5 includes a fixing block 511 fixedly connected to one side of the horizontal honing mill body 2. A rectangular hole 501 is provided on the fixing block 511. A limit rod 510 is fixedly connected between the two ends of the rectangular hole 501. Both ends of the rectangular hole 501 are... The slide is connected by two sliders 504, both of which slide through the limiting rod 510. Both sliders 504 have a round hole that matches the limiting rod 510. A pointer 505 is fixedly connected to the top of the side of each slider 504 away from the honing head 201. A screw 506 is screwed to the bottom of the side of each slider 504 away from the honing head 201. A knob 507 is fixedly connected to the outer end of each screw 506. A friction plate 508 is fixedly connected to the side of each knob 507 near the screw 506. A threaded hole that matches the screw 506 is opened at the bottom of each slider 504.

[0024] In this embodiment, the adjustment mechanism 5 also includes a scale 502 fixedly connected to the top of the side of the fixed block 511 away from the honing head 201, and the scale 502 is adapted to the pointer 505. Through the cooperation of the scale 502 and the pointer 505, the position of the sliding plate 401 moving with the workpiece can be precisely controlled. Two U-shaped friction plates 503 are fixedly connected to the ends of the fixed block 511 away from the honing head 201 and near the two ends of the rectangular hole 501. The two U-shaped friction plates 503 are adapted to the friction plates 508. Through the tight fit between the U-shaped friction plates 503 and the friction plates 508, the slider 504 is fixedly fixed. The ends of the two sliders 504 that are far apart from each other on the side near the honing head 201 are fixedly connected to the stop blocks 509. The two stop blocks 509 can limit the reciprocating sliding position of the sliding plate 401.

[0025] In this embodiment, guide rods 4 are fixedly connected to both ends of the horizontal honing machine body 2 near the honing head 201. The same sliding plate 401 is slidably sleeved on the circumferential surface of the two guide rods 4. Both ends of the sliding plate 401 are provided with round holes that are compatible with the guide rods 4. A fixing clamp 402 is fixedly connected to the middle of the top of the guide rod 4 by bolts. The workpiece is fixed by the cooperation of the sliding plate 401 and the fixing clamp 402, which facilitates processing.

[0026] In this embodiment, a drive mechanism 3 is fixedly connected to the end of the horizontal honing machine body 2 near the honing head 201 and away from the adjustment mechanism 5. The drive mechanism 3 includes a rectangular frame 310 fixedly connected to one end of the horizontal honing machine body 2. A reciprocating lead screw 301 is rotatably connected between the two ends of the inner side of the rectangular frame 310. A screw block 302 is screwed onto the circumferential surface of the reciprocating lead screw 301. The screw block 302 fits into the interior of the rectangular frame 310. A lead screw sleeve is fixedly sleeved in the middle of the screw block 302. A pin hole is provided on the inner circumferential surface of the lead screw sleeve along its radial direction. A crescent pin that cooperates with the reciprocating lead screw 301 is provided in the pin hole.

[0027] In this embodiment, the driving mechanism 3 further includes a round rod 304 fixedly connected between the two ends of the bottom of the rectangular frame 310. A strip plate 305 is slidably fitted on the circumferential surface of the round rod 304, and a round hole adapted to the round rod 304 is opened at the bottom of the strip plate 305. The strip plate 305 fits against the inner wall of the rectangular frame 310, and a rectangular groove 307 is opened at the top of the strip plate 305. The same connecting rod 308 is fixedly connected between the two ends of the rectangular groove 307, and the connecting rod 308 slides through the bottom of the screw block 302. The bottom of the connecting block 302 has a round hole that matches the connecting rod 308. Both ends of the connecting rod 308 are fitted with springs 309. The springs 309 are designed so that when the screw block 302 moves back and forth, the rectangular groove 307 carrying the sliding plate 401 is blocked by the stop block 509, which does not affect the reciprocating movement of the screw block 302. The outer end of the rectangular frame 310 is fixedly connected to the drive motor 303, and the output end of the drive motor 303 passes through the rectangular frame 310 and is fixedly connected to one end of the reciprocating screw 301.

[0028] In this embodiment, the driving mechanism 3 also includes an L-shaped rod 306 fixedly connected to the bottom of the rectangular groove 307, and one end of the bottom of the L-shaped rod 306 is fixedly connected to one end of the sliding plate 401.

[0029] In this embodiment, both stops 509 are adapted to the end of the sliding plate 401 that is close to it.

[0030] Working Principle: During operation, the horizontal honing machine body 2 achieves fine processing of the workpiece through the rotation of the honing head 201. The workpiece is fixed on the sliding plate 401 by the cooperation of the sliding plate 401 and the fixing clamp 402, thus making contact with the honing head 201. The drive motor 303 is started, causing the screw block 302 to move reciprocally. The spring 309 at the bottom of the screw block 302 drives the rectangular groove 307 to move, causing the L-shaped rod 306 to move the sliding plate 401 reciprocally, making the workpiece move closer and further away from the honing head 201. When it is necessary to adjust the distance of the workpiece's reciprocating movement, the two knobs 507 are turned to separate the friction plate 508 from the U-shaped friction plate 503. At this time, the two sliders 504 slide, limiting the sliding distance of the sliding plate 401. The position of the sliders 504 is accurately positioned by checking the pointer 505 and the scale 502. When the positions of the two sliders 504 are confirmed... After positioning, the L-shaped rod 306 and the strip plate 305, driven by the drive motor 303, move the sliding plate 401 back and forth. When the other end of the sliding plate 401 contacts the stop block 509 and is limited, the screw block 302 continues to move, compressing one spring 309. When the screw block 302 moves to the other end, the spring 309 on that side is released, and the strip plate 305 continues to move until the sliding plate 401 contacts another stop block 509, making the rectangular groove 307 stationary and the spring 309 on the other side compressed. In this way, when the drive motor 303 moves the sliding plate 401 back and forth, it is not affected by the limitation of the adjustment mechanism 5. At the same time, the sliding plate 401 will only move back and forth between the two stops 509. When the workpiece does not need to move, the two sliders 504 are brought closer together by the stop drive mechanism 3 to achieve the positioning of the sliding plate 401, so that the sliding plate 401 will not move.
