Description

Technical Field

[0001] This application relates to the field of engine block assembly technology, and in particular to an engine block tray. Background Technology

[0002] Engine block trays are specialized tools used in engine assembly production lines. They are primarily used for engine assembly and require a certain lifespan, compatibility with multiple engine models, simple operation, and easy maintenance.

[0003] In the industry, cylinder block trays are used for assembly on the assembly line by flipping the cylinder blocks. Fixed support columns are compatible with a limited number of machine models, while adapting to multiple models generally involves disassembling process supports. Process supports require specialized material storage containers and space for placement.

[0004] In actual production and processing, it is necessary to position the oil pan surface and combustion chamber surface of the cylinder block in order to process different mechanisms on the cylinder block. However, the existing common trays can only position the oil pan surface or combustion chamber surface of the cylinder block individually, which has poor usability. Utility Model Content

[0005] To improve the usability of the tray, this application provides an engine block tray.

[0006] The engine cylinder block tray provided in this application adopts the following technical solution: An engine cylinder block tray includes a base plate, a mounting seat is bolted to the base plate, a plurality of floating pins are installed in the mounting seat, a top plate is bolted to the top of the mounting seat, and a plurality of through holes are provided on the top plate for the floating pins to slide in or out. The floating pin includes a first positioning pin and a second positioning pin. The first positioning pin is used to position the oil pan surface of the cylinder block, and the second positioning pin is used to position the combustion chamber surface of the cylinder block. A switching mechanism for locking or releasing the first positioning pin and the second positioning pin is installed between the base plate and the mounting base.

[0007] By adopting the above technical solution, when positioning the oil pan surface of the cylinder block is required, the first positioning pin can be locked by the switching mechanism, allowing the second positioning pin to float freely. After the cylinder block is placed on the mounting base, the first positioning pin is locked and cannot float freely, while the second positioning pin contacts the oil pan surface and is pressed back into the through hole. The oil pan surface of the cylinder block can then be positioned by the locked first positioning pin extending from the top plate. When positioning the combustion chamber surface of the cylinder block is required, the operator can lock the second positioning pin by the switching mechanism, allowing the first positioning pin to float freely. After the robotic arm flips the cylinder block so that the combustion chamber surface is placed on the mounting base, the locked second positioning pin extending from the top plate can position the combustion chamber surface, while the freely floating first positioning pin is pressed back into the top plate. By using the switching mechanism and the floating pin in combination, the tray can be made suitable for positioning the oil pan surface and combustion chamber surface of the cylinder block, improving the usability of the tray.

[0008] Preferably, the mounting base has a through-hole adapted to the plurality of floating pins; Each floating pin can be detachably mounted with a positioning shaft. The positioning shaft is perpendicular to the floating pin. The mounting base has a limiting waist hole through the sliding hole. The two ends of the positioning shaft are respectively slidably disposed in the two limiting waist holes. The mounting base has a first locking hole that extends radially through the sliding hole at the sliding hole. The first locking hole is located above the limiting waist hole. The floating pin has a second locking hole that extends radially through the floating pin. The floating pin is locked by a locking pin inserted into the first locking hole and the second locking hole. The bottom of the floating pin is fixedly connected to a rod, and a washer and a spring are coaxially sleeved on the lower part of the rod. The spring is pressed against the limit pin and the washer. The mounting base has several locking plates that are slidably installed inside, each corresponding to a floating pin. The locking plates are used to control the floating pin to float or lock. The switching mechanism is detachably connected to the locking plates.

[0009] By adopting the above technical solution, when it is necessary to lock the floating pin, the operator can press the limit pin back into the through hole, so that the first locking hole and the second locking hole are coaxial and the locking pin is inserted; when it is necessary to use the tray or to switch the first positioning pin and the second positioning pin, the operator pulls out the locking pin, and the floating pin moves upward under the action of the spring. At this time, the operator fixes the locking plate through the switching mechanism, and the floating pin can be controlled to be in a locked or free-floating state through the locking plate.

[0010] Preferably, the switching mechanism includes a mounting plate detachably mounted on the base plate, the mounting plate being positioned above a plurality of the locking plates; The locking plate has a through hole adapted to the insertion rod, and the top of the locking plate has a first latch and a second latch, with the second latch located between the first latch and the through hole; The mounting plate has several insertion holes that are compatible with the locking plate. Each insertion hole can be detachably installed with a pin. The end of the pin that extends into the bottom of the insertion hole is inserted into the first or second latch.

[0011] By adopting the above technical solution, when it is necessary to lock the floating pin, the operator can adjust the position of the locking plate so that the through hole on the locking plate is misaligned with the insertion rod, and the position of the locking plate is fixed by the pin. When the floating pin is pressed, the bottom end of the insertion rod is pressed against the locking plate, so that the floating pin cannot move up and down. When it is necessary to release the floating pin, the operator changes the position of the locking plate so that the through hole is directly below the pin, and the position of the locking plate is fixed by the pin. When the floating pin is pressed, the bottom end of the insertion rod can extend into the through hole, so that the floating pin can move up and down.

[0012] Preferably, a limiting groove is provided at the bottom of the locking plate, and a plurality of limiting posts corresponding to the locking plate are threadedly connected to the base plate, and the limiting posts are inserted into the limiting groove.

[0013] By adopting the above technical solution, the distance that the locking plate slides in or out can be limited by the limiting groove, thereby improving the convenience for operators to adjust the position of the locking plate.

[0014] Preferably, two pads are bolted to the top of the base plate, the two pads are located on both sides of a plurality of locking plates, and the two ends of the mounting plate are bolted to the top of the two pads respectively.

[0015] Preferably, a push-pull block is fixedly installed at the end of the locking plate that extends out of the mounting plate.

[0016] By adopting the above technical solution, the push-pull block makes it easier for operators to push or pull the locking plate, further improving the convenience of operators in adjusting the position of the locking plate.

[0017] Preferably, a pull ring is installed at the end of the locking pin.

[0018] By adopting the above technical solution, the pull ring allows operators to easily move the locking pin.

[0019] In summary, the engine block tray of this application has at least one of the following beneficial technical effects: 1. By combining and using the switching mechanism with the floating pin, the tray can be adapted to position the oil pan surface and combustion chamber surface of the cylinder block, thereby improving the usability of the tray; 2. When it is necessary to lock the floating pin, the operator can adjust the position of the locking plate so that the through hole on the locking plate is misaligned with the insert rod, and fix the position of the locking plate with the pin. When the floating pin is pressed, the bottom end of the insert rod is pressed against the locking plate, which prevents the floating pin from floating up and down. When it is necessary to release the floating pin, the operator changes the position of the locking plate so that the through hole is directly below the pin, and fixes the position of the locking plate with the pin. When the floating pin is pressed, the bottom end of the insert rod can extend into the through hole, allowing the floating pin to float up and down. Attached Figure Description

Detailed Implementation

[0023] The following combination Figures 1-2 This application will be described in further detail.

[0024] Example This application discloses an engine cylinder block tray. (Refer to...) Figures 1-2 It mainly includes a base plate 1, a mounting base 2 bolted to the base plate 1, a number of floating pins 3 installed in the mounting base 2, a top plate 4 bolted to the top of the mounting base 2, and a number of through holes 41 through the top plate 4 for the floating pins 3 to slide in or out; the floating pins 3 include a first positioning pin and a second positioning pin, the first positioning pin is used to position the oil pan surface of the cylinder block, and the second positioning pin is used to position the combustion chamber surface of the cylinder block; a switching mechanism 5 for locking or releasing the first positioning pin and the second positioning pin is installed between the base plate 1 and the mounting base 2.

[0025] When the oil pan surface of the cylinder block needs to be positioned, the first positioning pin can be locked by the switching mechanism 5, and the second positioning pin can float freely. After the cylinder block is placed on the mounting base 2, the first positioning pin is locked and cannot float freely. The second positioning pin contacts the oil pan surface and is pressed back into the through hole 41. The oil pan surface of the cylinder block can be positioned by locking the first positioning pin that extends out of the top plate 4. When the combustion chamber surface of the cylinder block needs to be positioned, the operator can lock the second positioning pin by the switching mechanism 5, and the first positioning pin can float freely. After the robot flips the cylinder block so that the combustion chamber surface of the cylinder block is placed on the mounting base 2, the locked second positioning pin that extends out of the top plate 4 can position the combustion chamber surface of the cylinder block, and the freely floating first positioning pin is pressed back into the top plate 4.

[0026] By using the switching mechanism 5 in conjunction with the floating pin 3, the tray can be positioned for the oil pan surface and combustion chamber surface of the cylinder block, thereby improving the usability of the tray.

[0027] Reference Figure 1 and Figure 2 The mounting base 2 has a sliding hole 21 that is adapted to several floating pins 3. Each floating pin 3 is threaded with a positioning shaft 31, which is perpendicular to the floating pin 3. The mounting base 2 has a limiting waist hole 22 through the sliding hole 21, and the two ends of the positioning shaft 31 are respectively slidably set in the two limiting waist holes 22.

[0028] The mounting base 2 has a first locking hole 23 that is radially through the sliding hole 21. The first locking hole 23 is located above the limiting waist hole 22. The floating pin 3 has a second locking hole 32 that is radially through it. The floating pin 3 is locked by a locking pin 6 inserted in the first locking hole 23 and the second locking hole 32.

[0029] The bottom of the floating pin 3 is fixedly connected to the insertion rod 33. The lower part of the insertion rod 33 is coaxially fitted with a washer 34 and a spring 35. The spring 35 is pressed between the limit pin and the washer 34. Several locking plates 7 corresponding to the floating pin 3 are slidably installed in the mounting base 2. The locking plates 7 are used to control the floating pin 3 to float or lock. The switching mechanism 5 is detachably connected to several locking plates 7.

[0030] When it is necessary to lock the floating pin 3, the operator can press the limit pin back into the through hole 41, so that the first locking hole 23 and the second locking hole 32 are coaxial and the locking pin 6 is inserted; when it is necessary to use the tray or switch the first positioning pin and the second positioning pin, the operator pulls out the locking pin 6, and the floating pin 3 moves upward under the action of the spring 35. At this time, the operator fixes the locking plate 7 through the switching mechanism 5. The floating pin 3 can be controlled to be in a locked or free-floating state through the locking plate 7.

[0031] Reference Figure 1 and Figure 2 The switching mechanism 5 includes a mounting plate 51 that can be detachably mounted on the base plate 1. The mounting plate 51 is mounted above a plurality of locking plates 7. A through hole 73 adapted to the insertion rod 33 is provided through the locking plate 7. A first latch 71 and a second latch 72 are provided on the top of the locking plate 7. The second latch 72 is located between the first latch 71 and the through hole 73. A plurality of insertion holes 52 adapted to the locking plate 7 are provided on the mounting plate 51. A pin 53 is detachably installed in each insertion hole 52. The end of the pin 53 that extends into the bottom of the insertion hole 52 is inserted into the first latch 71 or the second latch 72.

[0032] When it is necessary to lock the floating pin 3, the operator can adjust the position of the locking plate 7 so that the through hole 73 on the locking plate 7 is misaligned with the insertion rod 33 and the position of the locking plate 7 is fixed by the pin 53. When the floating pin 3 is pressed, the bottom end of the insertion rod 33 is pressed against the locking plate 7, so that the floating pin 3 cannot float up and down. When it is necessary to release the floating pin 3, the operator changes the position of the locking plate 7 so that the through hole 73 is directly below the pin 53 and the position of the locking plate 7 is fixed by the pin 53. When the floating pin 3 is pressed, the bottom end of the insertion rod 33 can extend into the through hole 73, so that the floating pin 3 can float up and down.

[0033] Reference Figure 2 The bottom of the locking plate 7 has a limiting groove 74, and the base plate 1 is threaded with several limiting posts 11 corresponding to the locking plate 7. The limiting posts 11 are inserted into the limiting groove 74. The limiting groove 74 can limit the distance that the locking plate 7 can slide in or out, improving the convenience for the operator to adjust the position of the locking plate 7.

[0034] Reference Figure 1 Two pads 12 are bolted to the top of the base plate 1. The two pads 12 are located on both sides of several locking plates 7. The two ends of the mounting plate 51 are bolted to the top of the two pads 12 respectively.

[0035] Reference Figure 1 A push-pull block 75 is fixedly installed on the end of the locking plate 7 that extends out of the mounting plate 51. The push-pull block 75 makes it easy for the operator to push or pull the locking plate 7, further improving the convenience of the operator to adjust the position of the locking plate 7.

[0036] Reference Figure 1 A pull ring 61 is installed at the end of the locking pin 6. The pull ring 61 allows the operator to easily move the locking pin 6.

[0037] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
