Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of feeding equipment, and in particular relates to a feeding device for an eccentric shaft grinder. Background Art
[0002] A workpiece whose outer circle is parallel to the axis of the outer circle but does not coincide is called an eccentric shaft.
[0003] In mechanical transmission, the conversion of rotary motion into reciprocating linear motion or reciprocating linear motion into rotary motion is generally accomplished by using eccentric parts. For example, the lubrication pump driven by the eccentric workpiece in the headstock of a lathe, the crankshaft in a car engine, etc.
[0004] like Figure 1 As shown, in order to facilitate fixation during use, the existing eccentric shaft 1 generally has coaxial bosses 11 at both ends, and an eccentric portion 12 is provided at the remaining portion, thereby forming a complete eccentric shaft.
[0005] When there is only one eccentric part 12, the center of gravity of the eccentric shaft 1 is offset relative to the central axis of the boss 11. If the eccentric shaft 1 is placed horizontally and a supporting mechanism is used to vertically support the boss 11 of the eccentric shaft 1, the eccentric shaft 1 will automatically deflect under the action of gravity.
[0006] However, when there are multiple eccentric parts 12, the center of gravity of the eccentric shaft 1 may still be on the central axis of the boss 11, and it is impossible to utilize its own gravity to automatically deflect to a limited position, thereby making it impossible for the mechanical clamp used in the feeding process to correctly grasp the eccentric shaft 1. Summary of the invention
[0007] The purpose of the present invention is to provide a feeding device for an eccentric shaft grinder, so as to solve the problem that the existing feeding device cannot cooperate with the mechanical clamp to correctly grasp the eccentric shaft.
[0008] In order to achieve the above technical objectives, the technical solution adopted by the present invention is as follows: An eccentric shaft grinding machine loading device, comprising: Mounting frame; Two mutually parallel support rails mounted on the mounting frame; A mobile frame located between the two support rails, the mobile frame comprising two mutually parallel cross bars, the cross bars are parallel to the support rails, and a connecting rod is vertically arranged on the lower end surface of the cross bars; The support rail and the cross bar are used to support the boss of the eccentric shaft. The upper end surfaces of the support rail and the cross bar are provided with a plurality of V-shaped placement grooves, and the plurality of V-shaped placement grooves are linearly and evenly arranged; A guide mechanism installed on the mounting frame, the guide mechanism comprising a guide plate, a side of the guide plate is provided with an annular guide groove, the guide groove is composed of a first vertical groove, a first transverse groove, a second vertical groove, a second transverse groove, a third vertical groove and a third transverse groove connected end to end in sequence, the length dimension of the first vertical groove is smaller than the length dimension of the third vertical groove, and the first transverse groove is located below the second transverse groove; A rotating motor is mounted on the mounting frame, a swing arm is fixedly mounted on the power output shaft of the motor, a strip groove is provided on the swing arm, a roller is slidably mounted in the strip groove, one end of the roller is slidably mounted in the guide groove, and the other end is rotatably mounted on the connecting rod; A transverse slide rail mounted on the mounting frame, a vertical guide rail being slidably mounted on the transverse slide rail, and the connecting rod being slidably mounted on the vertical guide rail; An adjusting mechanism installed on the mounting frame and located above the supporting rail, the adjusting mechanism comprising an adjusting plate and two auxiliary blocks, wherein the distance between the two auxiliary blocks is equal to the diameter of the eccentric portion of the eccentric shaft; When the roller is located in the first transverse groove, the distance between the lower end surface of the adjusting plate and the central axis of the boss is smaller than the radius of the eccentric portion and larger than the shortest distance between the outer side surface of the eccentric portion and the central axis of the boss; When the roller is located in the second vertical groove, the inner side surfaces of the two auxiliary blocks are at equal distances from the vertical plane where the center axis of the boss is located.
[0009] It is further defined that the guide groove has rounded corners at its corners.
[0010] This structural design, through the setting of rounded corners, makes the roller slide more smoothly during the movement in the guide groove, which is more practical. It is further defined that the lower end surface of the regulating piece close to one end of the first vertical groove is inclined from top to bottom toward the auxiliary block.
[0011] Such a structural design forms a guiding effect by inclining one end of the adjusting plate, so that the eccentric shaft runs more smoothly and is more practical.
[0012] It is further defined that the regulating piece and the auxiliary block adjacent to the regulating piece are integrally formed.
[0013] Such a structural design can reduce the number of parts and components and make manufacturing more convenient by integrally forming the adjusting plate and one of the auxiliary blocks.
[0014] It is further defined that the auxiliary block is laterally slidably mounted on a mounting frame, and a first locking mechanism for locking the auxiliary block is mounted on the mounting frame.
[0015] Such a structural design, through the lateral sliding installation of the auxiliary block, cooperates with the first locking mechanism, can guide the eccentric shafts of different diameters, has a wider range of applications and is more practical.
[0016] It is further defined that the adjusting piece is vertically slidably mounted on a mounting frame, and a second locking mechanism for locking the adjusting piece is mounted on the mounting frame.

[0018] It is further defined that the upper end surface of the cross bar is inclined downward from the outside to the inside, and the inner side surface of the cross bar is in contact with the intersection surface of the boss and the eccentric portion.
[0019] Such a structural design, through the inclined setting of the upper end surface of the cross bar, can utilize the inclination to adjust the axial position of the eccentric shaft to a certain extent when the diameter of the eccentric part is larger than the diameter of the boss, which is more convenient to use and has strong practicality.
[0020] It is further defined that at least one of the support rails is height-adjustable; The length of at least one of the connecting rods is adjustable.
[0021] Such a structural design, through the adjustable setting of the support rail and the connecting rod, can be used when the diameters of the two bosses of the same eccentric shaft are different, so that the central axes of the two bosses of the eccentric shaft located on the support rail and the cross bar remain in the same horizontal plane, which has a wider adaptability.
[0022] The invention adopting the above technical solution has the following advantages: The eccentric shaft on the support rail is forked by the cross bar, and the eccentric shaft is driven to move upward to leave the support rail, and then move horizontally, and the central axis of the eccentric part of the eccentric shaft is not located above the central axis of the boss by the adjustment plate, and then the eccentric part of the eccentric shaft is adjusted for the second time by the two auxiliary blocks when the roller passes through the second vertical groove, so that when the eccentric shaft is re-placed on the support rail, the central axis of the eccentric part is always in the same position relative to the central axis of the boss, so as to facilitate the mechanical gripper to correctly grasp the eccentric shaft; BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0024] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that in the drawings or descriptions of the specification, similar or identical parts use the same figure numbers, and the implementation methods not shown or described in the drawings are forms known to ordinary technicians in the relevant technical field. In addition, the directional terms mentioned in the embodiments, such as "upper", "lower", "top", "bottom", "left", "right", "front", "back", etc., are only referenced to the directions of the drawings and are not used to limit the scope of protection of the present invention.
[0025] like Figures 1 to 13 As shown, an eccentric shaft grinding machine loading device of the present invention comprises: Mounting frame; Two mutually parallel support rails 2 mounted on the mounting frame; A mobile frame located between the two support rails 2, the mobile frame comprising two mutually parallel cross bars 3, the cross bars 3 are parallel to the support rails 2, and a connecting rod 30 is vertically arranged on the lower end surface of the cross bars 3; The support rail 2 and the cross bar 3 are used to support the boss 11 of the eccentric shaft 1. The upper end surfaces of the support rail 2 and the cross bar 3 are provided with a plurality of V-shaped placement grooves 20, and the plurality of V-shaped placement grooves 20 are linearly and evenly arranged; A guide mechanism installed on the mounting frame, the guide mechanism includes a guide plate 4, a side of the guide plate 4 is provided with an annular guide groove, the guide groove is composed of a first vertical groove 41, a first transverse groove 410, a second vertical groove 42, a second transverse groove 420, a third vertical groove 43 and a third transverse groove 430 connected end to end in sequence, the length dimension of the first vertical groove 41 is smaller than the length dimension of the third vertical groove 43, and the first transverse groove 410 is located below the second transverse groove 420; A rotating motor is mounted on a mounting frame, a swing arm 5 is fixedly mounted on the power output shaft of the motor, a strip groove 51 is provided on the swing arm 5, a roller 52 is slidably mounted in the strip groove 51, one end of the roller 52 is slidably mounted in the guide groove, and the other end is rotatably mounted on the connecting rod 30; A transverse slide rail 31 is mounted on the mounting frame, a vertical guide rail 32 is slidably mounted on the transverse slide rail 31, and a connecting rod 30 is slidably mounted on the vertical guide rail 32; An adjusting mechanism installed on the mounting frame and located above the supporting rail 2, the adjusting mechanism comprising an adjusting piece 61 and two auxiliary blocks 62, the distance between the two auxiliary blocks 62 being equal to the diameter of the eccentric portion 12 of the eccentric shaft 1; When the roller 52 is located in the first transverse groove 410, the distance between the lower end surface of the adjusting piece 61 and the central axis of the boss 11 is smaller than the radius of the eccentric portion 12 and larger than the shortest distance between the outer side surface of the eccentric portion 12 and the central axis of the boss 11; When the roller 52 is located in the second vertical groove 42 , the inner side surfaces of the two auxiliary blocks 62 are equidistant from the vertical plane where the center axis of the boss 11 is located.
[0026] The corners of the guide groove are provided with rounded corners.
[0027] In fact, the corner of the guide groove can also be set to a right angle according to actual conditions. In this embodiment, the rounded corner is set so that the roller 52 slides more smoothly during the movement in the guide groove, which is more practical. The lower end surface of the regulating piece 61 close to one end of the first vertical groove 41 is inclined from top to bottom toward the auxiliary block 62 .
[0028] In fact, according to actual conditions, guiding structures such as rounded corners and arc-shaped edges can be selected to guide the eccentric portion 12. In this embodiment, a guiding effect is formed by inclining one end of the adjusting piece 61, so that the eccentric shaft 1 runs more smoothly and is more practical.
[0029] The adjusting piece 61 and the auxiliary block 62 close to the adjusting piece 61 are integrally formed.
[0030] In fact, the adjusting piece 61 and the auxiliary block 62 can also be manufactured separately according to actual conditions. In this embodiment, the adjusting piece 61 and one of the auxiliary blocks 62 are integrally formed, which can reduce the number of parts and facilitate manufacturing.
[0031] The auxiliary block 62 is installed on the mounting frame in a transverse sliding manner, and a first locking mechanism for locking the auxiliary block 62 is installed on the mounting frame.
[0032] In fact, the auxiliary block 62 can also be fixedly installed on the mounting frame according to actual conditions. This embodiment can guide the eccentric shaft 1 of different diameters through the lateral sliding installation of the auxiliary block 62 in conjunction with the first locking mechanism, which has a wider range of applications and greater practicality.
[0033] The adjusting piece 61 is vertically slidably mounted on the mounting frame, and a second locking mechanism for locking the adjusting piece 61 is mounted on the mounting frame.
[0034] In fact, the adjusting piece 61 can also be fixedly installed on the mounting frame according to actual conditions. Since the range of action of the adjusting piece 61 is wider than that of the auxiliary block 62, it itself has a certain limited adaptability range, so it does not need to be adjusted. This embodiment can guide the eccentric shaft 1 of different diameters through the vertical sliding installation of the adjusting piece 61 in conjunction with the second locking mechanism, which has a wider range of application and stronger practicality.
[0035] The first locking mechanism and the second locking mechanism can both be fixing bolts.
[0036] The upper end surface of the cross bar 3 is inclined downward from the outside to the inside, and the inner side surface of the cross bar 3 is in contact with the interface between the boss 11 and the eccentric portion 12 .
[0037] In fact, the upper end surface of the cross bar 3 can also be set as a horizontal plane according to actual conditions. In this embodiment, by tilting the upper end surface of the cross bar 3, when the diameter of the eccentric part 12 is larger than the diameter of the boss 11, the axial position of the eccentric shaft 1 can be adjusted to a certain extent by utilizing the tilt, which is more convenient to use and more practical.
[0038] The height of at least one support rail 2 is adjustable; The length of at least one connecting rod 30 is adjustable.
[0039] In fact, the support rail 2 and the connecting rod 30 can also be directly fixed according to actual conditions. In this embodiment, the support rail 2 and the connecting rod 30 are adjustable. When the diameters of the two bosses 11 of the same eccentric shaft 1 are different, the adjustable setting of the support rail 2 and the connecting rod 30 can be utilized, so that the central axes of the two bosses 11 of the eccentric shaft 1 located on the support rail 2 and the cross bar 3 are still in the same horizontal plane, which has a wider range of adaptability.
[0040] In this embodiment, when in use, the eccentric shaft 1 is located in the V-shaped placement groove 20 on the left side of the support rail 2; The motor drives the swing arm 5 to rotate clockwise. When the roller 52 is located in the first vertical groove 41, the cross bar 3 moves upward under the action of the connecting rod 30, thereby vertically pushing the eccentric shaft 1 located on the support rail 2, driving the eccentric shaft 1 to move upward until the eccentric shaft 1 is separated from the V-shaped placement groove 20 of the support rail 2 (such as Figure 8 shown); The swing arm 5 continues to rotate, driving the roller 52 from the first vertical groove 41 into the first transverse groove 410. At this time, the crossbar 3 moves transversely to the right, driving the eccentric shaft 1 on the crossbar 3 to move to the right. During this process, the eccentric portion 12 of the eccentric shaft 1 passes under the adjusting piece 61, and the adjusting piece 61 is used to squeeze the eccentric portion 12 whose central axis is higher than the central axis of the boss 11, so that the eccentric portion 12 whose central axis is higher than the central axis of the boss 11 is deflected, and then the central axis of the eccentric portion 12 is located below the central axis of the boss 11 (such as Fig. 9 shown); The swing arm 5 continues to rotate, driving the roller 52 from the first transverse groove 410 into the second vertical groove 42. At this time, the crossbar 3 moves vertically upward, driving the eccentric shaft 1 located on the crossbar 3 to move upward. During this process, the eccentric portion 12 of the eccentric shaft 1 passes between the two auxiliary blocks 62. The two auxiliary blocks 62 squeeze the two sides of the eccentric portion 12, so that the central axis of the boss 11 and the central axis of the eccentric portion 12 are in the same vertical plane (such as Fig.10 shown); The swing arm 5 continues to rotate, driving the roller 52 from the second vertical groove 42 into the second transverse groove 420. At this time, the cross bar 3 moves transversely to the right, driving the eccentric shaft 1 on the cross bar 3 to move to the right (such as Fig.11 shown); The swing arm 5 continues to rotate, driving the roller 52 from the second transverse groove 420 into the third vertical groove 43. At this time, the cross bar 3 moves downward transversely, driving the eccentric shaft 1 on the cross bar 3 to move downward, until the eccentric shaft 1 on the cross bar 3 is re-seated on the support rail 2 and in the new V-shaped placement groove 20, and the cross bar 3 is separated from the eccentric shaft (such as Fig.12 shown); The swing arm 5 continues to rotate, driving the roller 52 from the third vertical groove 43 into the third transverse groove 430. At this time, the cross bar 3 moves horizontally to the left, driving the eccentric shaft 1 on the cross bar 3 to move left until it is reset (such as Fig.13 as shown).
[0041] The above is a detailed introduction to an eccentric shaft grinder feeding device provided by the present invention. The description of the specific embodiment is only used to help understand the method and its core idea of the present invention. It should be pointed out that for ordinary technicians in this technical field, without departing from the principle of the present invention, several improvements and modifications can be made to the present invention, and these improvements and modifications also fall within the scope of protection of the claims of the present invention.
