Description

Technical Field

[0001] This invention relates to the field of conveying equipment technology, and more specifically, to a conveying system for the production of machine tool castings. Background Art

[0002] Cast steel balls are widely used in mining grinding, bearing manufacturing, precision instruments and other fields. Their surface quality and mechanical properties directly affect the efficiency and life of downstream equipment. After production, the cast steel balls can be transported by a cylindrical conveying system with built-in threaded guide plates. During the transport process, the steel balls are thrown, and the friction and collision between the balls and the cylinder wall and between the balls remove residual sand, oxide scale, burrs and other defects from casting, eliminate internal stress and improve mechanical strength.

[0003] However, existing cylindrical conveyor systems suffer from large drop amplitudes and low frequencies of cast steel balls. This results in large collision amplitudes and low frequencies for the cast steel balls. To ensure that the steel balls can fully engage in friction and collision to achieve the desired processing effect, a longer conveyor system is required to accommodate multiple drops and collisions of the steel balls at different positions. This directly leads to a large length requirement for the entire cylindrical conveyor system, resulting in a bulky equipment. The excessive drop amplitude of the steel balls causes them to experience excessive impact forces when colliding with the cylinder wall or other steel balls. Such excessive impact forces can easily cause defects such as notches and damage on the surface of the steel balls, seriously affecting the surface quality and mechanical properties of the steel balls and reducing the yield rate.

[0004] In summary, how to reduce the collision amplitude and increase the collision frequency of cast steel balls while ensuring effective processing, thereby reducing the length requirement of the cylindrical conveyor system, reducing the equipment volume, and improving the yield of steel balls, has become an urgent technical problem to be solved. In view of this, we propose a conveyor system for the production of machine tool castings. Summary of the Invention

[0005] The purpose of this invention is to provide a conveying system for machine tool casting production, so as to solve the technical problems of large collision amplitude and low frequency when the existing cylindrical conveying system conveys cast steel balls.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a conveying system for the production of machine tool castings, comprising a base, a rotating mechanism, a conveying mechanism, a storage mechanism, and a feeding mechanism;

[0007] The rotating mechanism is fixed to the top of the base;

[0008] The conveying mechanism includes an outer conveying pipe and a mounting base B. The outer conveying pipe is fixed to the rotating end of the rotating mechanism. A conveying ring pipe is provided inside the outer conveying pipe. The inner surface of the conveying ring pipe has a plurality of circular cavities at equal intervals. At least one straight groove is provided on each circular cavity. A conveying column is provided inside the conveying ring pipe. The surface of the conveying column has a plurality of grooves at equal intervals. The gap between any two adjacent grooves forms a collision protrusion. The gap between the surface of the conveying column and the plurality of circular cavities forms a plurality of collision conveying cavities. The outer conveying pipe, the conveying ring pipe, and the conveying column are connected by a gear set. The mounting base B is located at the head end of the outer conveying pipe and is fixedly connected to the top end of the base. An input channel is provided inside the mounting base B.

[0009] The storage mechanism is located on the head side of the conveying mechanism, and the output end of the storage mechanism passes through the base and is connected to the input channel;

[0010] The feeding mechanism is located in the gap between the storage mechanism and the mounting base B. This invention drives the outer conveying pipe to rotate via a rotating mechanism, causing the conveying ring pipe and conveying column to rotate, and several collision conveying chambers to rotate. The threaded collision protrusions collide with the cast steel balls, resulting in small-amplitude, high-frequency collisions within the collision conveying chambers. This ensures that the steel balls can fully engage in frictional collisions during conveying to achieve the desired processing effect, while simultaneously reducing the size requirements of the conveying equipment and minimizing damage to the cast steel balls during transport.

[0011] Preferably, the inner surface of the outer conveying tube is uniformly provided with a plurality of threaded protrusions, and the tail end of the outer conveying tube is provided with an inner toothed ring.

[0014] Preferably, a connecting shaft is fixed on the conveying column, the inside of the conveying column is hollow to form a cavity, the collision protrusion has a threaded structure, and the surface of the groove is adapted to the segmental cavity.

[0015] Preferably, the gear set includes a mounting base A, which is fixed to the top of the base. The head end of the mounting base A has an inner and outer structure with annular grooves A and B respectively. The annular groove A is rotatably connected to the tail end of the conveying ring pipe, and the annular groove B is rotatably connected to the tail end of the conveying outer pipe. The tail ends of the annular groove A and the tail ends of the annular groove B are connected by a plurality of gear grooves A arranged in a ring at equal intervals. A gear A is rotatably connected in the gear groove A, and the two ends of the gear A are respectively meshed with the internal gear ring and the double-sided gear ring.

[0016] Preferably, the mounting base A has a gear groove C, and a gear C is rotatably connected in the gear groove C. The tail end of the coupling passes through the gear groove C and is fixedly connected to the gear C. The gear groove C and the annular groove A are connected through a plurality of gear grooves B arranged in an annular and equally spaced structure. A gear B is rotatably connected in the gear groove B. Both ends of the gear B are respectively meshed with the gear C and the double-sided gear ring. The lower part of the mounting base A has an output inclined groove that communicates and cooperates with the pre-stored inclined groove.

[0017] Preferably, the bottom end of the mounting base B is provided with a placement groove;

[0018] The input channel includes a horizontal groove, the top of which is connected to a vertical groove. The output end of the storage mechanism passes through the base and is connected to the vertical groove. A reserved arc groove is provided at the bottom of the horizontal groove.

[0019] Preferably, the feeding mechanism includes a mounting base C, a motor, a rotating shaft, a slider, a pusher, and a sleeve. The mounting base C is disposed in the gap between the storage mechanism and the mounting base B. The motor is fixedly mounted on the head end of the mounting base C. The rotating shaft is rotatably mounted on the tail end of the mounting base C. The head end of the rotating shaft passes through the mounting base C and is fixedly connected to the output shaft of the motor. The slider is fixedly mounted on the tail end of the rotating shaft. The pusher is slidably mounted on the slider. The sleeve is sleeved on the pusher. Both ends of the sleeve are fixedly connected to the mounting base C and the mounting base B, respectively. A reciprocating guide groove is formed on the inner surface of the sleeve. A ball block is movably disposed in the reciprocating guide groove. The ball block is fixedly connected to the pusher.

[0020] Preferably, the reciprocating guide groove includes two symmetrically arranged semi-threaded guide grooves, and the two semi-threaded guide grooves are connected to form a closed reciprocating channel.

[0021] The beneficial effects of the present invention are:

[0022] 1. This invention drives the outer conveying pipe to rotate through a rotating mechanism, causing the conveying ring pipe and the conveying column to rotate, and several collision conveying chambers to rotate. The collision protrusions with a threaded structure collide with the cast steel balls, so that the steel balls collide with each other at a small amplitude and high frequency within the collision conveying chambers. This ensures that the steel balls can fully engage in frictional collisions during conveying to achieve the ideal processing effect, while reducing the volume requirements of the conveying equipment and reducing damage to the cast steel balls during conveying.

[0023] 2. This invention uses several matching protrusions uniformly fixed on the surface of the segmental cavity to limit the casting steel balls and waste, preventing them from accumulating at the tail of the segmental cavity. The matching protrusions and collision protrusions work together to form local blocking points, breaking the laminar flow of the steel balls during transport. This forces the group of casting steel balls to turn randomly at high frequency, increasing the probability of multi-angle collisions and avoiding the uneven surface treatment problem caused by traditional unidirectional throwing. This ensures the collision effect of the steel balls in the collision transport cavity.

[0024] 3. The present invention uses a gear set to drive the outer conveying tube to rotate through a rotating mechanism. The inner gear ring drives the double-sided gear ring to rotate through gear A, which in turn drives gear C to rotate. The above structure has an acceleration effect, which enables the connecting shaft to drive the conveying column to rotate quickly. This facilitates small-amplitude, high-frequency collisions of the cast steel balls. The relatively slow rotation of the outer conveying tube allows the waste material to be conveyed at the bottom of the waste conveying chamber, reducing the risk of the waste material being thrown by centrifugal force and re-entering the collision conveying chamber.

[0025] 4. This invention provides several pre-storage grooves on a double-sided toothed ring at positions corresponding to several cleft cavities. This allows a cast steel ball to be stored in each of the several collision conveying cavities after collision, thereby controlling the collision time of the cast steel ball. When one of the pre-storage grooves is connected to the output groove, the cast steel ball is output from the output groove, achieving overall interval management during the output of the cast steel ball and avoiding uneven processing caused by free rolling in traditional processes.

[0026] 5. This invention utilizes a vertical groove pre-stored cast steel balls, and a reciprocating guide groove consisting of two symmetrically arranged semi-threaded guide grooves connected together. When the motor output shaft rotates, the shaft drives the slider and push column to rotate, causing the ball block to move within the reciprocating guide groove. This causes the push column to perform an outward and retracting action, achieving continuous operation with the motor output shaft rotating in the same direction. When the push column retracts, the cast steel balls at the bottom of the vertical groove fall into a reserved arc groove, which prevents the cast steel balls from rolling out. When the push column performs the outward action, it pushes the cast steel balls into the gaps between two matching protrusions near the bottom of the collision conveying cavity. Compared with the traditional conveying method that uses the gravity of the cast steel balls to roll in, the input of cast steel balls is more stable. The outward phase of the push column is strictly synchronized with the rotation position of the collision conveying cavity, ensuring that the steel balls are input without delay and accurately controlling the feed amount.

[0043] like Figures 1 to 8 As shown, the present invention relates to a conveying system for the production of machine tool castings, comprising a base 1, a rotating mechanism 2, a conveying mechanism 3, a storage mechanism 4, and a feeding mechanism 5;

[0044] In an embodiment of the present invention, the rotating mechanism 2 is fixedly mounted on the top of the base 1. The rotating mechanism 2 of the present invention is prior art and will not be described in detail here.

[0045] In an embodiment of the present invention, the conveying mechanism 3 includes a conveying outer pipe 31, a conveying ring pipe 32, a conveying column 33, and a mounting base B35;

[0046] The outer conveying tube 31 is fixed to the rotating end of the rotating mechanism 2. A plurality of threaded protrusions 311 are uniformly fixed on the inner surface of the outer conveying tube 31, and an internal toothed ring 312 is fixed at the tail end of the outer conveying tube 31. Through the above-mentioned arrangement, the rotating mechanism 2 can drive the outer conveying tube 31 to rotate, so that the waste material on the outer conveying tube 31 can be discharged.

[0047] The conveying ring pipe 32 is located inside the conveying outer pipe 31. The gap between the conveying ring pipe 32 and the conveying outer pipe 31 forms a waste conveying cavity. The inner surface of the conveying ring pipe 32 is provided with a number of annularly spaced cavities 321. The surface of the annular cavity 321 is uniformly provided with a number of matching protrusions 322. The cross-section of the matching protrusions 322 is arc-shaped. At least one straight groove 323 is provided on the annular cavity 321. The straight groove 323 is connected to the waste conveying cavity. The tail end of the conveying ring pipe 32 is provided with a double-sided toothed ring 324. The double-sided toothed ring 324 is provided with a number of pre-stored inclined grooves 325 relative to the positions of the annular cavities 321.

[0048] The conveying column 33 is located inside the conveying ring tube 32. A connecting shaft 331 is fixed on the conveying column 33. The inside of the conveying column 33 is hollow to form a cavity. The surface of the conveying column 33 is provided with several grooves 332 at equal intervals in an annular shape. The gap between any two adjacent grooves 332 forms a collision protrusion. The collision protrusion has a threaded structure. The surface of the groove 332 is adapted to the segmental cavity 321.

[0049] The surface of the conveying column 33 and the gaps between the several circular cavities 321 form several collision conveying cavities. Through the above arrangement, the present invention allows the conveying ring pipe 32 and the conveying column 33 to rotate, and the several collision conveying cavities to rotate. The threaded collision protrusions collide with the cast steel balls, resulting in small-amplitude, high-frequency collisions within the collision conveying cavities. This ensures that the steel balls can fully engage in frictional collisions during conveying to achieve the desired processing effect, while simultaneously reducing the size requirements of the conveying equipment and minimizing damage to the cast steel balls during transport.

[0050] Furthermore, this invention uses several matching protrusions 322 uniformly fixed on the surface of the segmental cavity 321 to limit the casting steel balls and waste, preventing the casting steel balls and waste from accumulating at the tail of the segmental cavity 321. The matching protrusions 322 and the collision protrusions work together to form local blocking points, breaking the laminar flow motion of the steel balls during transportation, forcing the group of casting steel balls to turn randomly at high frequency, increasing the probability of multi-angle collision of the casting steel balls, avoiding the problem of uneven surface treatment caused by traditional unidirectional throwing, thereby ensuring the collision effect of the steel balls in the collision conveying cavity.

[0051] In an embodiment of the present invention, the outer conveying pipe 31, the conveying ring pipe 32, and the conveying column 33 are connected by a gear set 34. The gear set 34 includes a mounting base A341, which is fixed to the top of the base 1. The head end of the mounting base A341 has an inner and outer structure with annular grooves A342 and B343 respectively. Annular groove A342 is rotatably connected to the tail end of the conveying ring pipe 32, and annular groove B343 is rotatably connected to the tail end of the outer conveying pipe 31. The tail ends of annular grooves A342 and B343 are connected by a plurality of gear grooves A344 arranged in a ring at equal intervals. Gears A345 are rotatably connected in the gear grooves A344. The ends are respectively meshed with the internal gear ring 312 and the double-sided gear ring 324. The mounting base A341 has a gear groove C346, and a gear C347 is rotatably connected in the gear groove C346. The tail end of the connecting shaft 331 passes into the gear groove C346 and is fixedly connected to the gear C347. The gear groove C346 and the ring groove A342 are connected by a number of gear grooves B348 arranged in a ring with equal spacing. A gear B349 is rotatably connected in the gear groove B348. The two ends of the gear B349 are respectively meshed with the gear C347 and the double-sided gear ring 324. The lower part of the mounting base A341 has an output inclined groove 340 that communicates and cooperates with the pre-stored inclined groove 325. The present invention, through the above-mentioned arrangement, enables the rotating mechanism 2 to drive the outer conveying tube 31 to rotate, the inner toothed ring 312 to drive the double-sided toothed ring 324 to rotate through the gear A345, the conveying ring tube 32 to rotate, and the gear B349 to drive the gear C347 to rotate. The above structure has an acceleration effect, enabling the connecting shaft 331 to drive the conveying column 33 to rotate rapidly, which facilitates small-amplitude, high-frequency collisions of the cast steel balls.

[0052] Furthermore, by providing several pre-storage grooves 325 on the double-sided toothed ring 324 relative to several cleft cavities 321, the present invention ensures that a cast steel ball is stored in each of the several collision conveying cavities after collision. This achieves the effect of controlling the collision time of the cast steel ball. When one of the pre-storage grooves 325 is connected to the output groove 340, the cast steel ball is output from the output groove 340, realizing the overall interval management of the output of the cast steel ball and avoiding the uneven processing caused by free rolling in the traditional process.

[0053] In an embodiment of the present invention, the mounting base B35 is disposed at the head end of the conveying outer tube 31 and is fixedly connected to the top end of the base 1. The mounting base B35 is provided with an input channel, and the bottom end of the mounting base B35 is provided with a placement groove 351.

[0054] The input channel includes a horizontal groove 352, with a vertical groove 353 connected to the top of the horizontal groove 352, and a reserved arc groove 354 at the bottom of the horizontal groove 352. The position below the placement groove 351 of the present invention is used to place a collection box for collecting waste output from the waste conveying chamber.

[0055] The storage mechanism 4 is located on the head side of the conveying mechanism 3, and the output end of the storage mechanism 4 passes through the base 1 and is connected to the vertical groove 353.

[0056] In an embodiment of the present invention, the feeding mechanism 5 includes a mounting base C51, a motor 52, a rotating shaft 53, a slider 54, a pusher 55, and a sleeve 56. The mounting base C51 is disposed in the gap between the storage mechanism 4 and the mounting base B35. The motor 52 is fixedly disposed at the head end of the mounting base C51. The rotating shaft 53 is rotatably disposed at the tail end of the mounting base C51. The head end of the rotating shaft 53 passes through the mounting base C51 and is fixedly connected to the output shaft of the motor 52. The slider 54 is fixedly disposed at the tail end of the rotating shaft 53. The pusher 55 is slidably disposed on the slider 54. The sleeve 56 is sleeved on the pusher 55. The two ends of the sleeve 56 are fixedly connected to the mounting base C51 and the mounting base B35, respectively. A reciprocating guide groove 57 is provided on the inner surface of the sleeve 56. A ball block 58 is movably disposed in the reciprocating guide groove 57. The ball block 58 is fixedly connected to the pusher 55.

[0057] The reciprocating guide groove 57 includes two symmetrically arranged semi-threaded guide grooves, which are connected to form a closed reciprocating channel. Through the above-described configuration, this invention utilizes a vertical groove 353 pre-stored with cast steel balls, and a reciprocating guide groove 57, composed of two symmetrically arranged semi-threaded guide grooves connected together. When the output shaft of the motor 52 rotates, the rotating shaft 53 drives the slider 54 and the pusher 55 to rotate, causing the ball block 58 to move within the reciprocating guide groove 57. This causes the pusher 55 to perform an outward and retracting action, achieving continuous operation with the output shaft of the motor 52 rotating in the same direction. When the pusher 55 retracts, the cast steel ball at the bottom of the vertical groove 353 falls into the reserved arc groove 354, which prevents the cast steel ball from rolling out. When the pusher 55 performs the outward action, it pushes the cast steel ball into the gap between two matching protrusions 322 near the bottom of the collision conveying cavity, which has just rotated to the bottom. Compared with the traditional conveying method that uses the gravity of the cast steel ball to roll in, the input of the cast steel ball is more stable. The outward phase of the pusher 55 is strictly synchronized with the rotation position of the collision conveying cavity, ensuring that the steel ball is input without delay and accurately controlling the feed amount.

[0058] Working principle: This embodiment provides a conveying system for the production of machine tool castings. When in use, the cast steel balls on the storage mechanism 4 are pre-stored in the vertical groove 353. When the output shaft of the motor 52 rotates, the push column 55 performs a push-out and retraction action, pushing the cast steel balls into the gap between two matching protrusions 322 near the end of the push column 55 of the collision conveying cavity that has just rotated to the bottom. This allows the steel balls to be uniformly input into several collision conveying cavities without delay.

[0059] The rotating mechanism 2 drives the outer conveying tube 31 to rotate, and the inner toothed ring 312 drives the double-sided toothed ring 324 to rotate through the gear A345. The conveying ring tube 32 rotates, and the gear B349 drives the gear C347. The above structure has an acceleration effect, which causes the connecting shaft 331 to drive the conveying column 33 to rotate rapidly. The threaded collision protrusion collides with the cast steel ball, so that the steel ball collides with the small amplitude and high frequency in the collision conveying cavity.

[0060] When one of the pre-stored skewers 325 is connected to the output skewer 340, the cast steel ball is output from the output skewer 340.

[0061] The embodiments disclosed in this invention are preferred embodiments, but are not limited thereto. Those skilled in the art can easily understand the spirit of this invention based on the above embodiments and make different extensions and variations, but as long as they do not depart from the spirit of this invention, they are all within the protection scope of this invention.
