Description

Technical Field

[0001] The utility model relates to belt pulley processing equipment, in particular to a feeding mechanism for belt pulley processing. Background Art

[0002] Pulleys belong to the hub type parts and are mainly used in situations where power is transmitted over long distances, such as the output of power from small diesel engines, agricultural vehicles, tractors, automobiles, mining machinery, mechanical processing equipment, textile machinery, packaging machinery, lathes, forging machines, the transmission of power for some small horsepower motorcycles, the transmission of power for agricultural machinery, air compressors, reducers, speed reducers, generators, cotton gins, etc.

[0003] There are many drawbacks in the production process of pulleys: First, unqualified blanks will be produced in the production of pulleys, and the selection of various indicators and materials of pulleys is based on the principle of minimizing raw materials, feasible processes, and lowest costs while meeting the requirements of use. Therefore, large-sized unqualified blanks will be processed into small-sized pulleys. In the traditional pulley blank processing process, the blanks will be screened by the detection mechanism to determine whether they are qualified or not. Unqualified blanks will be pushed from the conveyor belt into the collection frame by the pushing mechanism. However, due to the large height of the conveyor belt surface and the collection frame of the conveying mechanism, the blanks will easily fall and cause local concave deformation, which will affect its reuse rate and increase the unqualified rate; secondly, the pulley production process needs to be accommodated by corresponding receiving plates such as receiving plates. Because there are many sizes of pulleys, the height difference of pulleys of different sizes is not large. If a unified deep-hole receiving plate is used to accommodate different small sizes The small pulley is not conducive to the clamping and placement of the robot, and a uniform shallow-hole receiving plate is used. When the pulley is placed in the receiving groove of the receiving plate, there is a gap setting. When the driving mechanism pushes the receiving plate for transmission, the large-sized pulley placed in the shallow-hole receiving plate is easy to tip over due to insufficient stability. Therefore, corresponding receiving plates of different sizes are required, and different pulleys are placed in receiving plates of corresponding sizes. This makes the adaptability of the receiving plate low, which leads to higher equipment costs. During use, different receiving plates need to be replaced according to the size of the pulley, which is more cumbersome.

[0004] Therefore, on the basis of ensuring the screening of pulley processing blanks, the purpose of the present invention is to design a pulley processing feeding mechanism that can not only buffer the falling height of unqualified blanks, reduce or avoid the problem of local depression and deformation of unqualified blanks due to falling, but also ensure the stability of the pulley placed in the receiving tray and be suitable for stable loading of pulleys of different sizes, and effectively improve the applicability of use.

[0024] Advantages of the utility model:

[0025] 1) The utility model can not only realize the screening of the pulley processing blanks, but also buffer and guide the unqualified blanks, effectively reduce the impact force on the unqualified blanks when they fall, and then reduce or avoid the local deformation of the unqualified blanks due to falling, so that they can be processed into other small-sized blanks, improve the reuse rate of the pulley blanks, and reduce the unqualified rate; and the height adjustment mechanism and the adjustment and fixing mechanism cooperate with each other so that the receiving plate can be suitable for stably receiving and placing pulleys of different heights, and can effectively improve the stability of the pulley placement, and effectively prevent the pulley from tipping over during the push and transmission process of the receiving plate.

[0026] 2) The material blocking mechanism of the utility model includes an L-shaped material blocking member driven by a telescopic cylinder. The L-shaped material blocking member is hingedly mounted on a supporting frame. One end of the L-shaped material blocking member extends to one side of the unqualified blank discharge port of the conveyor belt, and the other end thereof is folded and extended outward to be provided with an elongated hole. The piston rod end of the telescopic cylinder is fixedly connected to a connector, and an axial rod penetrating the elongated hole is vertically fixedly connected to the connector. When the detection mechanism detects that the material is unqualified, the piston rod of the telescopic cylinder extends into place, and the end of the L-shaped material blocking member located on the conveyor belt is tilted from the hinge to the unqualified blank discharge port and connected to the unqualified blank discharge port, and cooperates with the conveying mechanism to guide and convey the unqualified blank, so that the unqualified blank can be smoothly discharged without affecting the conveying of other blanks, thereby ensuring a practical effect.

[0027] 3) The utility model is provided with a buffering guide mechanism for connecting the material collection frame at the unqualified blank discharge port. The buffering guide mechanism includes a group of upper slide members and lower slide members that are sleeved and slidably connected. The upper slide member is tilted and fixedly installed on the support frame corresponding to the unqualified blank discharge port. Both sides of the lower slide member are provided with corresponding first elastic members between the upper slide member, and the upper surface of the lower slide member is tilted downwardly fixedly connected with a corresponding material guide plate at the end that is not connected to the upper slide member. Generally, the inclined plate used for material guidance should not be too long. If the material is too long, the material will be stuck on the inclined plate due to friction. The required material collection frame is shorter, and the material collection frame needs to be replaced frequently due to the small number of blanks. In addition, a customized lower height material collection frame needs to be used. If the inclined plate is not long enough, the material discharge height is too high, and the material discharge is prone to local concave deformation problems, which affects the reuse rate and increases the unqualified rate. The utility model adds a buffer material guide mechanism with adjustable length. The length of the upper slide chute is shorter, ensuring that the sliding force of unqualified blanks is greater than the friction force, so that the upper slide chute not only plays the role of guiding materials but also can fix the lower slide chute. The blank slides to the lower slide chute and hits the guide plate. At this time, the lower slide chute moves downward, and the first elastic member is stretched to shorten the distance between the blank and the collection frame. The falling height of the blank is reduced, thereby effectively solving the problem of local depression caused by the high falling height. After the blank is discharged, the first elastic member is reset to drive the lower slide chute to reset.

[0028] 4) The utility model provides an embedding hole connected to the accommodating groove in a stepped shape downward at the bottom of the accommodating groove of the original receiving disc body, and then installs a height adjustment mechanism and an adjustment fixing mechanism between the embedding hole and the accommodating groove, and utilizes the gravity of the pulley to make the support plate connected to the second elastic member move downward, the second elastic member is compressed, and the adjustment fixing mechanism is driven to move downward when the support plate moves downward; the adjustment fixing mechanism includes a plurality of elastic steel plates respectively installed outwardly on the outer edges of the four sides of the support plate, and the elastic steel plates located on the opposite sides of the support plate are symmetrically arranged, and the top of the elastic steel plates is The end of the part extends outward and is placed on the outside of the accommodating groove. The supporting plate drives the elastic steel plate to move downward, and the elastic steel plate shrinks toward the middle due to the limitation of the accommodating groove. The inner fixed silicone member at the top end of the elastic steel plate is extruded and arranged between the pulley and the elastic steel plate, so that the elastic steel plate fixes the pulley, thereby effectively ensuring the stability of the pulley placement, and effectively preventing the pulley from tipping over during the process of the receiving plate being pushed and conveyed. Moreover, because the pulley is fixed by the height adjustment mechanism and the adjustment and fixing mechanism, it can also be applied to pulleys of higher sizes, thereby improving the practical effect of the utility model.

[0029] 5) The embedding hole of the utility model can ensure the compression stroke of the second elastic member, avoid deviation, and ensure the stability of the movement of the support plate; the second elastic member can ensure that the support plate is reset to its back to the embedding hole and the elastic steel plate is reset and opened when the pulley is taken out, so as to be used again. The utility model is provided with a smooth and flat buffer chamfer at the connection point where the receiving plate is located at the top of the accommodating groove, and a corresponding rubber member is provided on the outer side of the elastic steel plate at a position corresponding to the buffer chamfer. The buffer chamfer can protect the rubber member and avoid scratching the rubber member when the elastic steel plate moves downward; when the pulley is placed on the upper side of the support plate, the rubber member is squeezed and arranged between the elastic steel plate and the inner wall of the accommodating groove to further fix the pulley.

[0030] 6) When the receiving groove is a shallow hole groove, the utility model can extend the height of the elastic steel plate to make it higher than the height of the receiving groove, and thus can be suitable for the placement of higher-sized pulleys; when the receiving groove is a deep hole groove, the height of the elastic steel plate is smaller than the height of the receiving groove, and a stepped clamping area is provided on the outer side of the top end of the elastic steel plate, so that it has sufficient depth for the robot to enter the clamping area to clamp the pulley, which is suitable for lower-sized pulleys to ensure practical effects.

Both sides of the lower slide member 502 are provided with corresponding first elastic members 503 between the upper slide member 501, and the upper surface thereof is tilted downwardly and fixedly connected with corresponding guide plates 16 at the ends which are not connected to the upper slide member 501. The first elastic member 503 enables the lower slide member 502 to have a movement tendency of sliding and returning to the upper slide member 501. When the unqualified blank is discharged to the guide plate 16 along the buffer guide mechanism 5, the first elastic member 503 is stretched and the lower slide member 502 moves downward.

[0050] A material collecting frame 7 is arranged at the material discharging port of the buffer material guiding mechanism 5;

[0051] The transmission mechanism 8 is used to transmit the receiving plate 9, which is installed at the qualified blank discharge port 101 and is arranged perpendicularly to the transmission mechanism 1.

When the pulley blank 21 is placed on the upper side of the supporting plate 1301, the second elastic member 1302 is compressed and the supporting plate 1301 moves downward, and the elastic steel plate 1401 swings inward relatively to the silicone member 1402 and is extruded and arranged between the pulley blank 21 and the elastic steel plate 1401.

[0053] The utility model can not only realize the screening of the pulley blank 21 during processing, but also buffer and guide unqualified blanks, effectively reduce the impact force on the unqualified blanks when they fall, and thus reduce or avoid local deformation of the unqualified blanks due to falling, so that they can be processed into other small-sized blanks, thereby improving the reuse rate of the pulley blank 21 and reducing the unqualified rate; and the height adjustment mechanism 13 and the adjustment and fixing mechanism 14 cooperate with each other so that the receiving plate 9 can be suitable for stably receiving and placing pulley blanks 21 of different heights, and can effectively improve the stability of the placement of the pulley blank 21, and effectively prevent the pulley blank 21 from tipping over during the process of the receiving plate 9 being pushed and conveyed.

[0054] The conveying mechanism 1 includes a group of rolling rollers rotatably mounted on a supporting frame 6, a conveying belt 103 tensioned between the rolling rollers, and any one of the rolling rollers extending outwardly and connected to the output shaft end of the motor 104, and both sides of the conveying belt 103 are gap-arranged with limit bars 105 for limiting the pulley blank 21.

[0056] The material blocking mechanism 4 of the utility model comprises an L-shaped material blocking member 402 driven by a telescopic cylinder 401, the L-shaped material blocking member 402 is hingedly mounted on the support frame 6, one end of the L-shaped material blocking member 402 extends to the side of the unqualified blank discharge port 102 of the conveyor belt 103, and the other end thereof is folded and extended outwardly to be provided with an elongated hole 4021, the piston rod end of the telescopic cylinder 401 is fixedly connected with a connecting member 403, and a shaft 15 penetrating the elongated hole 4021 is vertically fixedly connected to the connecting member 403. When the detection mechanism 3 detects that the material is unqualified, the piston rod of the telescopic cylinder 401 extends into place, the end of the L-shaped material blocking member 402 located on the conveyor belt 103 is tilted from the hinge to the unqualified blank discharge port 102 and connected to the unqualified blank discharge port 102, and cooperates with the conveying mechanism 1 to guide and convey the unqualified blank, so that the unqualified blank is smoothly discharged without affecting the conveying of other blanks, thereby ensuring the practical effect.

Moreover, the required collection frame 7 is shorter, and the collection frame 7 needs to be replaced frequently due to the small number of blanks. Moreover, a customized collection frame 7 with a lower height needs to be adopted.

The utility model adds a buffer guide mechanism 5 with adjustable length, and the upper slide chute 501 is shorter, ensuring that the sliding force of unqualified blanks is greater than the friction force, so that the upper slide chute 501 not only plays the role of guiding materials but also can fix the lower slide chute 502. The blank slides to the lower slide chute 502 and hits the guide plate 16. At this time, the lower slide chute 502 moves downward, and the first elastic member 503 is stretched to shorten the distance between the blank and the collection frame 7. The falling height of the blank is reduced, thereby effectively solving the problem of local depression caused by the high falling height. After the blank is discharged, the first elastic member 503 is reset to drive the lower slide chute 502 to achieve reset.

The drive rollers 1201 are connected by chains and gears, and any one of the drive rollers 1201 extends outward and is connected to the output shaft end of the drive motor 1202.

[0060] The second elastic member 1302 is a small stiffness spring uprightly arranged in the embedding hole 902 , and the two ends of the small stiffness spring are respectively fixed to the support plate 1301 and the lower surface of the embedding hole 902 , and the width of the support plate 1301 is greater than the diameter of the embedding hole 902 .

[0061] The connection point of the receiving plate 9 at the top of the accommodating groove 901 is set as a smooth and flat buffer chamfer 903, and the outer side surface of the elastic steel plate 1401 is provided with a corresponding rubber part 20 at a position corresponding to the buffer chamfer 903; when the pulley blank 21 is placed on the upper side of the supporting plate 1301, the rubber part 20 is extruded and arranged between the elastic steel plate 1401 and the inner wall of the accommodating groove 901.

[0062] The utility model has an embedding hole 902 connected to the accommodating groove 901 in a stepped shape at the bottom of the original receiving plate 9 body, and then a height adjustment mechanism 13 and an adjustment fixing mechanism 14 are installed between the embedding hole 902 and the accommodating groove 901. The gravity of the pulley blank 21 is used to make the support plate 1301 connected to the second elastic member 1302 move downward, and the second elastic member 1302 is compressed. When the support plate 1301 moves downward, the adjustment fixing mechanism 14 is driven to move downward; the adjustment fixing mechanism 14 includes a plurality of elastic steel plates 1401 respectively installed outwardly on the outer edges of the four sides of the support plate 1301, and the elastic steel plates 1401 located on the opposite sides of the support plate 1301 are symmetrically arranged, and the top of the elastic steel plates 1401 The end extends outward and is placed on the outside of the accommodating groove 901. The support plate 1301 drives the elastic steel plate 1401 to move downward. At the same time, the elastic steel plate 1401 shrinks toward the middle due to the limitation of the accommodating groove 901, and the inner fixed silicone member 1402 at the top end of the elastic steel plate 1401 is extruded and arranged between the pulley blank 21 and the elastic steel plate 1401, so that the elastic steel plate 1401 fixes the pulley blank 21, thereby effectively ensuring the stability of the placement of the pulley blank 21, and effectively preventing the pulley blank 21 from tipping over during the process of the receiving plate 9 being pushed and conveyed. Moreover, since the pulley blank 21 is fixed by the height adjustment mechanism 13 and the adjustment and fixing mechanism 14, it can also be applied to pulley blanks 21 with higher sizes, thereby improving the practical effect of the utility model.

[0063] The embedding hole 902 of the utility model can ensure the compression stroke of the second elastic member 1302, avoid deviation, and ensure the stability of the movement of the support plate 1301; the second elastic member 1302 can ensure that the support plate 1301 is reset to the embedding hole 902 and the elastic steel plate 1401 is reset and opened when the pulley blank 21 is taken out, so as to be used again. The utility model is provided with a smooth planar buffer chamfer 903 at the connection point where the receiving plate 9 is located at the top of the receiving groove 901, and the outer side surface of the elastic steel plate 1401 is provided with a corresponding rubber member 20 at a position corresponding to the buffer chamfer 903. The setting of the buffer chamfer 903 can protect the rubber member 20 and avoid scratching the rubber member 20 when the elastic steel plate 1401 moves downward; when the pulley blank 21 is placed on the upper side of the support plate 1301, the rubber member 20 is squeezed and arranged between the elastic steel plate 1401 and the inner side wall of the receiving groove 901, further fixing the pulley blank 21.

[0064] The outer edges of the supporting plate 1301 are provided with gaps with the inner side walls of the corresponding receiving groove 901 . When the elastic steel plate 1401 is arranged upright, a gap is provided between it and the inner side walls of the receiving groove 901 .

[0065] When the receiving groove 901 is a shallow hole groove, the height of the elastic steel plate 1401 is greater than the height of the receiving groove 901. When the receiving groove 901 is a shallow hole groove, the height of the elastic steel plate 1401 can be extended to be higher than the height of the receiving groove 901, thereby being suitable for placing a pulley blank 21 of a higher size.

[0066] Embodiment 2

[0067] refer to Figure 10-11 , which is different from the first embodiment, is that when the receiving groove 901 is a deep hole groove, the height of the elastic steel plate 1401 is smaller than the height of the receiving groove 901, and the outer side of the top end of the elastic steel plate 1401 is arranged in a step shape to form a clamping area, and the rubber member 20 is arranged below the clamping area.

[0068] When the accommodating groove 901 is a deep hole groove, the height of the elastic steel plate 1401 is smaller than the height of the accommodating groove 901. By setting a stepped clamping area on the outer side of the top end of the elastic steel plate 1401, it has sufficient depth for the robot to enter the clamping area to clamp the pulley blank 21, which is suitable for pulley blanks 21 of lower sizes to ensure practical effects.

[0069] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
