Description

Technical Field

[0001] The invention relates to the technical field of assembly line support plates, and in particular to a noise-reducing and wear-resistant assembly line support plate. Background Art

[0002] Assembly line pallets are a commonly used load-bearing and transporting tool in industrial production lines, mainly used to support and transport products or materials on the assembly line.

[0003] The assembly line pallets will collide and generate a lot of noise during the circulation process, so the assembly line pallets need to be treated to reduce noise. Figure 8 As shown, existing assembly line pallets all use polyurethane buffer blocks for noise reduction, and these blocks are installed upstream of the pallet's flow direction, protruding from the edge of the pallet. However, in actual production activities, after a period of use, the polyurethane buffer blocks will deform due to wear. This dimensional change not only affects the pallet's flow but also causes the noise to continue to generate.

[0004] Therefore, how to reduce the noise when the pallet collides and reduce the wear of the polyurethane buffer block to achieve the normal flow of the assembly line pallet has become a technical problem that needs to be solved urgently by those skilled in the art. Summary of the Invention

[0005] In view of this, the purpose of the present invention is to provide a noise-reducing and wear-resistant assembly line pallet to reduce the noise when the pallet collides, extend the service life of the polyurethane buffer block, and ensure the normal flow of the assembly line pallet.

[0006] The technical solution adopted by the present invention is: a noise-reducing and wear-resistant assembly line support plate, comprising:

[0007] A support plate bottom plate, wherein a first mounting groove is formed on one lateral side of the support plate bottom plate, and a second mounting groove is formed on the other lateral side of the support plate bottom plate and is opposite to the first mounting groove;

[0008] A buffer block is installed in the first installation groove, and the impact surface of the buffer block is coplanar with the end surface of the lateral side of the support plate bottom plate;

[0009] The impact block is installed in the second installation groove, the impact surface of the impact block protrudes outward by 1 to 5 mm from the end surface on the other side of the support plate bottom plate, and the longitudinal dimension of the impact surface is smaller than the longitudinal dimension of the impacted surface.

[0010] Preferably, the impact surface of the impact block protrudes outward by 3 mm from the end surface on the other side of the support plate bottom plate.

[0011] Preferably, a connecting hole is formed in the second installation groove, a countersunk hole matching the connecting hole is formed on the collision block, and a fastener for detachably fixing the collision block to the bottom plate of the support plate is installed in the countersunk hole.

[0012] Preferably, the collision block is made of metal.

[0013] Preferably, a pressure plate is loaded above the buffer block, and both longitudinal ends of the pressure plate are detachably fixedly connected to the bottom plate of the support plate.

[0014] Preferably, threaded holes are provided on the bottom plate of the support plate, and the threaded holes are located on both longitudinal sides of the first mounting groove. Through holes are provided at both longitudinal ends of the pressure plate, and connecting screws are installed in the through holes, and the bottom ends of the connecting screws are threadedly connected to the threaded holes.

[0015] Preferably, the buffer block is made of polyurethane.

[0016] Preferably, the first mounting groove is a C-shaped groove, and the second mounting groove is a square groove.

[0017] Preferably, a blocking block is installed on one lateral side of the pallet bottom plate, and the blocking block is located between two buffer blocks.

[0020] Beneficial effects of the present invention:

[0021] The present invention installs a buffer block that is easy to wear and made of a softer material on the downstream side of the pallet base plate, and makes the impact surface of the buffer block flush with the outer contour of the pallet base plate, which can avoid wear of the buffer block against external equipment when it circulates on the assembly line, prolongs the service life of the buffer block, maintains the stability of the appearance of the assembly line pallet, and avoids the phenomenon of assembly line jamming; at the same time, a collision block is installed on the upstream side of the pallet base plate, and the impact surface of the collision block protrudes from the outer contour of the pallet base plate, so that when two adjacent assembly line pallets collide, the collision block can silently collide with the buffer block, thereby reducing the noise during the pallet circulation process.

[0038] The following is a further detailed description of the specific embodiments of the present invention in conjunction with the accompanying drawings. These embodiments are only used to illustrate the present invention, and are not intended to limit the present invention.

[0039] In the description of the present invention, it should be noted that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "back," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer" and the like, indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely to facilitate and simplify the description of the present invention. They are not intended to indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation, and therefore should not be construed as limiting the present invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0040] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0041] Furthermore, in the description of the present invention, unless otherwise specified, “plurality” means two or more.

[0042] After research, the inventor found that there are two reasons for the wear and deformation of the polyurethane buffer block on the assembly line pallet: the first is aging caused by the collision between the buffer block 20 and the pallet base plate 10; the second is that during the circulation of the assembly line pallet, as the circulation direction changes, the buffer block 20 will be located on one side of the pallet circulation direction, and the buffer block 20 protrudes from the outer contour of the pallet base plate 10, which is easy to rub against external equipment on both sides of the assembly line, thereby accelerating the wear and deformation of the buffer block 20, and then shortening the service life of the buffer block 20. Once the buffer block 20 fails, the pallet will collide and generate a lot of noise during the circulation process, thereby losing the silent effect.

[0043] Examples, such as Figure 1-Figure 7 As shown, a noise-reducing and wear-resistant assembly line support plate, the assembly line support plate comprises:

[0044] The pallet base plate 10 has a first mounting groove 11 formed on one lateral side thereof and a second mounting groove 12 opposite to the first mounting groove 11 formed on the other lateral side thereof.

[0045] The buffer block 20 is installed in the first installation groove 11 , and the impact-receiving surface 21 of the buffer block 20 is coplanar with the end surface of the lateral side of the support plate bottom plate 10 .

[0046] The impact block 30 is installed in the second installation groove 12 , and the impact surface 31 of the impact block 30 protrudes outward by 1 to 5 mm from the end surface on the other side of the support plate bottom plate 10 , and the longitudinal dimension of the impact surface 31 is smaller than the longitudinal dimension of the impacted surface 21 .

[0047] The present invention installs a buffer block 20 that is easy to wear and made of a softer material on the downstream side of the pallet base plate 10, and makes the impact surface 21 of the buffer block 20 flush with the outer contour of the pallet base plate 10, which can avoid the friction between the buffer block 20 and external equipment when it circulates on the assembly line, thereby reducing the wear of the buffer block 20, extending the service life of the buffer block 20, maintaining the stability of the shape of the assembly line pallet, and avoiding the assembly line jam phenomenon; at the same time, a collision block 30 is installed on the upstream side of the pallet base plate 10, and the impact surface 31 of the collision block 30 protrudes from the outer contour of the pallet base plate 10, so that when the front and rear assembly line pallets collide, the collision block 30 can silently collide with the buffer block 20, thereby reducing the noise during the pallet circulation process.

[0048] It should be noted that the horizontal direction refers to Figure 1 The single arrow direction in the vertical direction refers to Figure 1 In the direction of the double arrows, the pallet flows in the horizontal direction.

[0049] Specific embodiment 1, as Figure 1-Figure 7 As shown, a noise-reducing and wear-resistant assembly line support plate includes: a support plate base plate 10, a buffer block 20, a collision block 30, a pressure plate 40, a blocking block 50, a sensor block 60 and a positioning pin sleeve 70.

[0050] A first mounting groove 11 is formed on one lateral side of the pallet base plate 10, that is, a first mounting groove 11 is opened on the downstream side of the pallet base plate 10, the number of the first mounting grooves 11 is two, and the two first mounting grooves 11 are arranged at intervals along the longitudinal direction; a second mounting groove 12 is formed on the other lateral side of the pallet base plate 10, that is, a second mounting groove 12 is opened on the upstream side of the pallet base plate 10, the number of the second mounting grooves 12 is two, and the two second mounting grooves 12 are arranged at intervals along the longitudinal direction; the first mounting groove 11 is opposite to the second mounting groove 12, that is, the line connecting the first mounting groove 11 and the second mounting groove 12 is in the lateral direction.

[0051] The support plate base 10 is used to install various fixtures and can place or fix workpieces for processing, such as an air-conditioning compressor housing.

[0052] There are two buffer blocks 20, and the two buffer blocks 20 are fixedly installed in the two first installation grooves 11 in a one-to-one manner, and the buffer blocks 20 have a collision surface 21, which is coplanar with the end surface of the lateral side of the pallet bottom plate 10, that is, the collision surface 21 is coplanar with the downstream end surface of the pallet bottom plate 10.

[0053] Preferably, the buffer block 20 is made of polyurethane and has an overall cylindrical shape. The side surface of the buffer block 20 includes a circular arc surface and a flat surface. The two ends of the flat surface are fixedly connected to the two ends of the circular arc surface. The flat surface is the impact surface 21. The first mounting groove 11 on the support plate bottom plate 10 is a C-shaped groove adapted to the shape of the buffer block 20.

[0054] There are two pressing plates 40 , which are respectively loaded on the buffer block 20 , and the pressing plates 40 are detachably fixedly connected to the support plate bottom plate 10 .

[0055] Specifically, the vertical dimension of the buffer block 20 is greater than the groove depth dimension of the first mounting groove 11. The buffer block 20 is accommodated in the first mounting groove 11, and a pressure plate 40 is loaded above the buffer block 20. The pressure plate 40 is arranged in the longitudinal direction as a whole. A plurality of threaded holes 14 are formed on the pallet base 10. The threaded holes 14 are located on both longitudinal sides of the first mounting groove 11. Through holes are formed at both longitudinal ends of the pressure plate 40. Connecting screws (not shown in the figure) are installed in the through holes. The bottom ends of the connecting screws are threadedly connected to the threaded holes 14, so that the longitudinal ends of the pressure plate 40 are detachably fixed to the pallet base 10.

[0056] There are two impact blocks 30, and the two impact blocks 30 are installed in the second installation groove 12 in a one-to-one manner. The impact block 30 has an impact surface 31, and the impact surface 31 protrudes outward by 1 to 5 mm from the end surface on the other side of the pallet bottom plate 10, that is, the lateral spacing between the impact surface 31 and the upstream end surface of the pallet bottom plate 10 is 1 to 5 mm; in the longitudinal direction, the position of the impact block 30 on the pallet bottom plate 10 is opposite to the position of the buffer block 20 on the pallet bottom plate 10, and the longitudinal dimension of the impact surface 31 is smaller than the longitudinal dimension of the impacted surface 21, so that when the front and rear assembly line pallets collide, the impact surface 31 of the impact block 30 collides with the impacted surface 21 of the buffer block 20, and the impact surface 31 of the impact block 30 will not collide with the downstream end surface of the pallet bottom plate 10, thereby realizing silent contact collision between the front and rear pallets when the pallets are circulated.

[0057] Preferably, the collision block 30 is made of metal and has a square shape, and the second mounting groove 12 is a square groove.

[0058] The impact surface 31 of the impact block 30 protrudes outward by 3 mm from the end surface on the other side of the pallet bottom plate 10 so that the assembly line pallet has the same shape and size as the existing assembly line pallets.

[0059] Specifically, a connecting hole 13 is opened in the second mounting groove 12 along the vertical direction, and a countersunk hole 32 is opened in the vertical direction on the impact block 30. The countersunk hole 32 has a one-to-one correspondence with the connecting hole 13, and a fastener (not shown in the figure) is installed in the countersunk hole 32 for detachably fixing the impact block 30 to the pallet base plate 10. The fastener is preferably a screw.

[0060] The blocking block 50 is installed on one lateral side of the pallet base 10, and the blocking block 50 is located between the two buffer blocks 20. The blocking block 50 protrudes from the lower surface of the pallet base 10 so that when the pallet flows, the blocking block 50 can collide with the blocker on the assembly line, causing the assembly line pallet to stop flowing, so that the required operation can be carried out.

[0061] The sensing block 60 is installed on one lateral side of the pallet base plate 10 and is located at one longitudinal end of the pallet base plate 10 . The sensing block 60 is used to sense an external sensor to detect the position signal of the pallet.

[0062] The positioning pin sleeve 70 is installed on the pallet bottom plate 10, and there are two positioning pin sleeves 70. The positioning pin sleeve 70 can cooperate with the pallet lifting device on the assembly line to accurately position the pallet, so that the required operation can be carried out.

[0063] The noise reduction and wear resistance principle of the assembly line support plate of the present invention is as follows:

[0064] The present invention makes the polyurethane buffer block 20, which is easy to wear and made of a softer material, flush with the outer contour of the pallet base plate 10 instead of protruding, thereby avoiding the buffer block 20 from participating in the friction between the pallet base plate 10 and the external equipment when it circulates on the assembly line, thereby reducing the wear of the buffer block 20; a metal impact block 30 is installed on the other side of the pallet base plate 10, and the impact block 30 can silently collide with the buffer block 20. The impact block 30 can also be heat-treated, and the surface is wear-resistant, which not only solves the noise problem during the circulation of the pallet, but also avoids the assembly line jamming phenomenon caused by changes in the pallet's external dimensions.

[0065] Compared with the prior art, the present invention has at least the following beneficial technical effects:

[0066] The present invention avoids the friction between the polyurethane buffer block and external equipment, reduces the wear and deformation of the buffer block, extends the service life of the buffer block, and ensures the stability of the external dimensions of the assembly line support plate. It not only has the effect of reducing noise and silencing the flow of the support plate, making the silent effect of the support plate flow more lasting, but also can avoid the phenomenon of plate jamming or poor flow of the plate.

[0067] 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 substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
