Description

Technical Field

[0001] This utility model relates to the field of parts clamping tools, and more specifically, to a quick assembly trolley. Background Technology

[0002] In the clamping and transfer of product fixtures, trolleys are a commonly used handling tool, widely used in equipment manufacturing environments, assembly workshops, and other places. Existing transfer trolleys generally adopt a fixed structure or a simple adjustable structure, temporarily fixing the assembly fixtures to the trolley by bolting or pneumatic clamping blocks for assembly and transfer. However, mechanical locking structures, mostly for stability, make the disassembly and assembly steps cumbersome and increase the disassembly and assembly time, while electrically controlled locking structures are easily limited by long-distance displacement during transfer and cannot implement power supply control. As a result, existing transfer trolleys cannot effectively meet the fast and efficient transfer requirements of automated production.

[0003] Furthermore, assembly fixtures are coated with liquid or semi-solid oils such as rust-preventive oil and lubricating oil during use and storage. These oils are not cleaned during actual workshop production and assembly. Therefore, during transportation, these oils can easily drip from various assembly gaps onto the trolley or its bottom surface through vibration transmission. This not only easily contaminates the working environment but also accumulates on the trolley, increasing the difficulty of cleaning and further reducing its service life. Utility Model Content

[0004] The purpose of this application is to provide a rapid assembly trolley that solves the technical problem of rapid transfer of mechanical assembly fixtures and reduces oil pollution on the trolley during the transfer of assembly fixtures.

[0005] To solve the above-mentioned technical problems, the solution adopted in this application is as follows:

[0006] A quick-assembly trolley includes a frame with multiple casters mounted on the bottom of the frame.

[0007] Preferably, the top of the frame is equipped with an assembly plate, which has several sets of mounting slots. Each set of mounting slots has at least two mounting slots, and a quick-installation component is fitted inside the mounting slot.

[0008] Preferably, the quick-installation assembly includes a locking sleeve and a positioning locking shaft. The locking sleeve is detachably disposed in the mounting groove, and the positioning locking shaft is inserted to connect the locking sleeve and the assembly fixture.

[0009] Preferably, the lock sleeve includes a pin hole, and the positioning lock shaft includes a pin, with the pin vertically sliding through the pin hole.

[0010] Preferably, the lower end of the pin is provided with a sliding hole, and a ball is slidably disposed in the sliding hole, and the ball is connected to the inner wall of the sliding hole by a spring.

[0011] Preferably, the sliding end of the sliding hole passes through the outer wall of the pin to form a through hole, and the diameter of the through hole is smaller than the diameter of the ball.

[0012] Preferably, a baffle is fixedly provided on the top of the pin, and the baffle abuts against the surface of the assembly fixture after the pin passes through the pin hole.

[0013] Preferably, an oil-draining component is also provided below the assembly plate.

[0014] Preferably, the locking sleeve further includes a retaining plate, which is fitted into the mounting groove, and the retaining plate and the mounting groove are matched and locked by threaded screws.

[0015] Preferably, the card plate has a pin hole vertically inserted through its center.

[0016] Preferably, a tapered groove is provided on the outer edge of the pin hole at the lower end of the card plate. When the ball at the lower end of the pin passes through the pin hole, the ball elastically abuts against the surface of the tapered groove.

[0017] Preferably, the lower end of the pin is provided with at least two balls, and the plurality of balls are evenly distributed around the pin hole as the axis.

[0018] Preferably, each of the multiple balls is provided with a corresponding sliding hole and spring.

[0019] Preferably, the oil-draining assembly includes an oil-draining plate.

[0020] Preferably, the oil drain plate is fixedly installed on the top of the vehicle frame, and multiple support columns are fixedly installed on the oil drain plate, with the top of the support columns abutting against the bottom surface of the assembly plate.

[0021] Preferably, the oil drain plate has an oil collection port through it, and the oil collection port is equipped with an openable and closable valve.

[0022] Preferably, the outer edge of the oil-draining plate is further provided with a raised sheet metal ring, which together with the oil-draining plate forms an oil-draining groove.

[0023] Preferably, a sealing ring is also fitted onto the pin, and the sealing ring is located above the ball.

[0024] Preferably, the sealing ring is an elastic rubber ring.

[0025] Preferably, when the ball passes through the pin hole, the sealing ring elastically abuts against the inner wall of the pin hole.

[0026] The technical solution of this application has at least the following advantages and beneficial effects:

[0027] This invention utilizes several mounting slots and matching quick-release components on a trolley to flexibly install and lock according to the needs of different assembly fixtures, enabling the rapid transfer of one or more sets of fixtures. Furthermore, by setting up a quick-release locking sleeve that cooperates with a positioning locking shaft, and using the cooperation of a pin and a pin hole, the movement of the assembly fixture is positioned and restricted, improving stability during transfer. The elastic locking structure between the ball bearing and the pin hole allows the ball bearing to elastically abut against the tapered groove after passing through the pin hole. The abutment between the top baffle of the pin and the assembly fixture effectively prevents the pin from loosening due to vibration during transportation. This allows for rapid installation and disassembly of the assembly fixtures without the need for additional tools, thereby improving the efficiency of trolley transfer and assembly fixture assembly / disassembly.

[0028] This invention provides an oil-draining component located below the assembly plate, which works in conjunction with the mounting groove on the assembly plate to collect oil droplets from the assembly fixture. This prevents oil contamination of the trolley and the working environment, and extends the service life of the trolley and its quick-assembly components. Attached Figure Description

[0038] Example

[0039] Please refer to Figures 1-6 This utility model provides a quick assembly trolley for quickly positioning and installing one or more sets of assembly fixtures and for transporting them. It includes a frame 1, with multiple casters 2 fixedly installed at the bottom of the frame 1 for moving and transporting. The casters 2 are equipped with self-locking components, which can lock the entire trolley in place after transporting it to the designated location (the casters 2 with self-locking are common components and will not be described in detail).

[0040] Please refer to Figure 1 The frame 1 has an assembly plate 3 mounted on top. The assembly plate 3 has several sets of mounting slots 4, and each set of mounting slots 4 has at least two mounting slots 4. A quick-release assembly 5 is fitted inside the mounting slot 4. When the assembly fixture is placed on the assembly plate 3, it can be quickly locked and installed on the assembly plate 3 by matching the quick-release assembly 5 with the mounting slot 4, and then transported by a trolley.

[0041] Preferably, the assembly plate 3 is provided with several sets of mounting slots 4, which can quickly lock multiple sets of assembly fixtures onto the trolley for rapid transfer with the corresponding quick-release components 5, thereby increasing transfer efficiency.

[0042] Furthermore, to achieve rapid locking of the assembly fixture, please refer to... Figures 4-6 In this embodiment, the quick-installation component 5 includes a locking sleeve 51 and a positioning locking shaft 52. The locking sleeve 51 is detachably disposed in the mounting groove 4, which facilitates disassembly and replacement to replace different quick-installation components 5 for different assembly fixtures. The positioning locking shaft 52 can be quickly inserted into the locking sleeve 51 and the assembly fixture to lock the assembly fixture on the assembly plate 3.

[0043] The locking sleeve 51 includes a retaining plate 511, a threaded hole 512, a pin hole 513, and a tapered groove 514.

[0044] The positioning lock shaft 52 includes a pin 521, a sliding hole 522, a ball 523, a spring 524, and a sealing ring 525.

[0045] Specifically, the clamping plate 511 is fitted into the mounting groove 4. Both the clamping plate 511 and the mounting groove 4 are provided with threaded holes 512 and corresponding through holes, so that the clamping plate 511 is fixed to the mounting groove 4 by matching threaded screws and can be disassembled and replaced at any time. The center of the clamping plate 511 is provided with a pin hole 513, and a pin 521 slides vertically through the pin hole 513. The assembly fixture is also provided with a corresponding pin hole 513. When placing the assembly fixture, the pin 521 is passed through the pin hole 513 of both the assembly fixture and the clamping plate 511 at the same time, so that the position of the assembly fixture can be quickly positioned and its installation can be stable.

[0046] Each set of lock sleeves 51 contains at least two pins 521 and pin holes 513 corresponding to the mounting slots 4, which can also limit the assembly fixture to a minimum and restrict its movement.

[0047] While achieving rapid transfer, quick installation and disassembly are also required before and after transfer. The assembly fixture needs to be able to be locked in a quick-release manner. Therefore, a horizontal sliding hole 522 space is provided inside the lower end of the pin 521. A ball 523 is horizontally slidably arranged in the sliding hole 522. The two ends of the spring 524 are fixedly connected to the inner wall of the sliding hole 522, so that there is an elastic force between the ball 523 and the sliding hole 522. The sliding end of the sliding hole 522 passes through the outer wall of the pin 521 to form a through hole. The diameter of the through hole is smaller than the diameter of the ball 523, so that a small part of the ball 523 (less than half of its volume) can pass through the side wall of the pin 521 and contact the pin hole 513 wall of the clamping plate 511, but it also restricts the ball 523 from sliding out of the pin 521 as a whole.

[0048] A tapered groove 514 is provided on the outer edge of the pin hole 513 at the lower end of the clamping plate 511. A baffle is fixedly provided on the top of the pin 521. When installing the assembly fixture, the pin 521 passes through the pin hole 513 of the assembly fixture and the clamping plate 511 in sequence. At this time, the ball 523 at the lower end of the pin 521 is squeezed by the wall of the pin hole 513. The squeezing force is greater than the elastic force of the spring 524, and the ball 523 is pressed back into the sliding hole 522 of the pin 521, so that the pin 521 can be inserted normally. After the pin 521 passes through the clamping plate 511, the lower end of the pin 521 is located in the tapered groove 514, so that the sliding hole 522... The ball bearing 523 inside is no longer squeezed by the wall of the pin hole 513. Under the elastic force, the ball bearing 523 extends out of the pin 521 and abuts against the groove surface of the conical groove 514. The resistance of the conical groove 514 increases the difficulty for personnel to pull the pin 521 upward, making it less likely for the pin 521 to come out of the pin hole 513 due to vibration during trolley transportation. When the ball bearing 523 contacts the conical groove 514, the baffle at the top of the pin 521 also abuts against the surface of the assembly fixture, thereby restricting the vertical movement of the entire pin 521, fixing the pin 521, maintaining the stability of the positioning, and locking the assembly fixture.

[0049] When it is necessary to remove the assembly fixture on the assembly plate 3, the pin 521 can be manually pulled upwards. When the pulling force is greater than the elastic force, the ball 523 will be squeezed into the sliding hole 522, so that the pin 521 can be pulled out smoothly. The whole process does not require additional disassembly tools, and the disassembly time is shorter than that of conventional threaded fastening.

[0050] It is worth noting that, please refer to Figure 6 In order to increase the stability when the ball 523 abuts against the tapered groove 514, at least two balls 523 are provided at the lower end of the pin 521. The multiple balls 523 are evenly distributed around the pin hole 513 as the axis, so that the relative forces of the balls 523 on the lower end of the pin 521 are relatively balanced. Each ball 523 is matched with a sliding hole 522 and a spring 524.

[0051] Furthermore, the assembly fixtures transported by trolley may include brand-new fixtures just taken from the warehouse and older fixtures removed from existing equipment. Brand-new fixtures are coated with protective oil after production to extend their lifespan and prevent metal oxidation and rust. Older fixtures, however, accumulate lubricating oil from products or equipment during continuous use. When these fixtures are manually moved and installed onto the trolley, the various oily substances on the fixtures can easily leak into the trolley due to vibrations (vibration accelerates the flow of semi-liquid and semi-solid oily substances within the fixtures). This leads to oil accumulation on the trolley over extended use, reducing its lifespan and increasing the difficulty of cleaning.

[0052] Therefore, please refer to the above information regarding the issues mentioned above. Figure 2 In this embodiment, an oil-draining component 6 is also provided on the frame 1. The oil-draining component 6 is located below the assembly plate 3 and is used to collect oily substances leaking from the assembly fixtures on the assembly plate 3 for centralized treatment to reduce their pollution to the trolley.

[0053] The oil draining component 6 includes an oil draining plate 61, a support column 62, and an oil collection port 63.

[0054] Specifically, the oil drain plate 61 is fixedly installed on the top of the frame 1. Multiple support columns 62 are fixedly installed on the oil drain plate 61. The top of the support column 62 abuts against the bottom surface of the mounting plate 3. The top of the mounting plate 3 and the support column 62 are respectively provided with threaded holes 512 and through holes, so that the mounting plate 3 is threadedly locked onto the support column 62. The support column 62 supports the mounting plate 3, and the mounting plate 3 can be quickly disassembled through the threaded lock for easy replacement. The outer edge of the oil drain plate 61 is also provided with a sheet metal ring. The raised sheet metal ring on the outer edge makes the entire oil drain plate 61 form an oil draining groove, which is convenient for storing oily substances. An oil collection port 63 is passed through the surface of the oil drain plate 61, and an openable and closable valve is provided at the oil collection port 63.

[0055] Preferably, when the assembly fixture is installed on the assembly plate 3 and transported by trolley, oily substances gradually drip onto the surface of the assembly plate 3, and then fall through several mounting grooves 4 on the assembly plate 3 into the surface of the oil-draining plate 61 below, thus collecting the oily substances and preventing excessive accumulation on the assembly plate 3, which could then seep into the frame 1 and quick-assembly components 5, affecting their service life. After a certain amount has been collected, personnel can connect an oil pipe to the oil collection port 63 and open the valve to remove the oily substances from the oil-draining plate 61.

[0056] It is worth noting that, please refer to Figure 5To reduce the impact of oil on the positioning of the pin hole 513 of the quick-assembly assembly 5, a sealing ring 525 is also fitted on the pin 521. The sealing ring 525 is located above the ball 523 and is made of rubber, which is elastic. When the pin 521 is inserted into the pin hole 513 and the ball 523 passes through the pin hole 513 and abuts against the tapered groove 514, the sealing ring 525 is located inside the pin hole 513. At this time, the sealing ring 525 is squeezed and elastically contracts after being squeezed inside the pin hole 513 (a groove is provided on the outer wall of the pin 521 corresponding to the sealing ring 525 so that the sealing ring 525 will not fail to elastically contract due to pin positioning), thereby providing sealing pressure between the pin 521 and the pin hole 513, thereby reducing the possibility of oil on the assembly plate 3 and the assembly fixture entering the pin hole 513 and maintaining the positioning and locking effect.

[0057] The various embodiments of this utility model have now been described in detail. To avoid obscuring the concept of this utility model, some details known in the art have not been described. Those skilled in the art will fully understand how to implement the technical solution of this utility model based on the above description. The scope of this utility model is defined by the appended claims.
