Description

Technical Field

[0001] The invention belongs to the field of product assembly equipment, in particular to an expansion water tank assembly test integrated workbench. Background Art

[0002] The expansion tank is an indispensable and important component in the cooling circulation system. Its main function is to contain and circulate the coolant to ensure the normal operation of the system. In the process of manufacturing the expansion tank, a series of assembly and testing operations need to be completed, including the assembly of key accessories such as quick connectors, liquid level switches and pressure relief valves, as well as the testing of the sealing of the expansion tank and the working conditions of various accessories.

[0003] At present, the manufacturing process of the expansion tank has the following problems: First, during the assembly process, the expansion tank needs to be placed in a horizontal state to facilitate the installation of accessories such as quick connectors, liquid level switches and pressure relief valves. This horizontal placement can provide a stable operating platform and facilitate the use of assembly tools. However, after the assembly is completed, the expansion tank needs to be switched from a horizontal state to a vertical state for coolant filling and sealing testing.

[0004] Currently, there are operating platforms for horizontal assembly of expansion water tanks and test platforms for vertical testing, but the two platforms are split-type designs, and the expansion water tanks need to be frequently moved, loaded and unloaded, and calibrated during assembly, testing, and adjustment. This frequent state switching not only increases the complexity of operation and labor intensity, but also reduces work efficiency. Summary of the invention

[0005] The purpose of the present invention is to provide an integrated workbench for assembling and testing an expansion water tank, so as to solve the problems raised in the above-mentioned prior art.

[0006] Provided is an expansion water tank assembly test integrated workbench, comprising:

[0007] A workbench frame, which includes a profile frame and a driving mechanism;

[0008] The turning platform is rotatably connected to the profile frame, and the driving mechanism is used to drive the turning platform to rotate.

[0009] As a further solution of the present invention: the turning table includes a profile frame, a static fixing seat and a movable fixing seat, wherein the static fixing seat is fixedly connected to one end of the profile frame, and the movable fixing seat can slide on the other end of the profile frame. The expansion water tank is placed on the profile frame, the static fixing seat fixes one end, and the movable fixing seat slides to an appropriate position to lock the water tank. In the turning table structure, the expansion water tank is fixed by a combination of a static fixing seat and a movable fixing seat. The release or locking operation is achieved by sliding the movable fixing seat, and it can be adjusted to adapt to water tanks of different sizes, thereby improving the adaptability of the workbench, being able to support expansion water tanks of various specifications, and enhancing the versatility of the equipment.

[0010] As a further solution of the present invention: the movable fixing seat comprises a movable fixing plate, a movable motor, a gear, a rack and a sliding connection block, the two ends of the movable fixing plate are respectively slidably connected to the profile frame through the sliding connection blocks, the body of the movable motor is fixedly connected to the movable fixing plate, the rack is fixedly connected to the profile frame, and the output shaft of the movable motor is meshed with the rack through the gear. The movable fixing seat is driven by the movable motor to slide along the rack, and the position is accurately adjusted by the meshing of the gear and the rack and then fixed, so as to ensure that the expansion water tank is stably placed without deviation.

[0011] As a further solution of the present invention: the turning platform further comprises a stop profile, which is fixedly connected to the profile frame and is used to limit the freedom of the water tank to slide along the length direction of the movable fixing seat. After the water tank is placed and fixed by the movable fixing seat and the static fixing seat, the stop profile provides additional support to prevent the water tank from sliding in the radial direction of the turning platform's rotation axis due to the influence of gravity during the turning process of the turning platform.

[0012] As a further solution of the present invention: connecting shafts are respectively provided at both ends of the flip table, and the two ends of the flip table are respectively rotatably connected to two bearing seats on the profile frame through the connecting shafts, and the driving mechanism is a flip motor, and the output shaft of the driving mechanism is drivingly connected to at least one connecting shaft. The connecting shafts at both ends of the flip table are connected to the profile frame through the bearing seats, and the driving mechanism provides a rotational driving force to complete the flipping operation. After the flip motor is started, the flip table is driven to rotate through the connecting shaft to change the placement state of the water tank.

[0013] As a further solution of the present invention, a fall arrester is arranged on the connecting shaft. When the turning platform loses control in an abnormal state, the fall arrester automatically engages to prevent the turning platform from falling freely and hitting outwards under the action of inertia, thereby protecting the water tank and the operator.

[0014] As a further solution of the present invention: the anti-fall device includes a gear ring, a rotating pin and a locking wheel, the gear ring is fixed to the inner wall of the bearing seat, the rotating pin is fixedly connected to the connecting shaft, and the locking wheel is sleeved on the outer periphery of the rotating pin and is in clearance with the rotating pin. When the connecting shaft rotates normally and slowly at a uniform speed, the rotating pin drives the locking wheel to rotate, and the locking wheel and the gear ring remain in a non-contact state. When the turning platform stalls abnormally, the locking wheel moves in a certain direction under the action of eccentricity and meshes with the gear ring, thereby limiting the rotation of the connecting shaft and realizing the anti-fall function of the turning platform.

[0015] As a further solution of the present invention: a leakage tray is provided on the profile frame, and a leakage valve is provided on the leakage tray. During the test, possible leakage of coolant is received by the leakage tray, and after the test, the leaked liquid is discharged through the leakage valve, thereby ensuring the cleanliness of the test environment, reducing the pollution of the workbench and the environment by liquid leakage, and improving the environmental performance of the equipment.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] The expansion water tank workbench consists of a workbench frame and a turning table. The workbench frame provides a stable basic structure and rotation drive function for the assembly and testing of the expansion water tank through a profile frame and a driving mechanism. The turning table can be rotated under the drive of the driving mechanism, so that the expansion water tank installed on the turning table can be switched between a horizontal state and a vertical state. After the expansion water tank is assembled in a horizontal state, the turning table is driven by the driving mechanism to rotate to a vertical state for coolant filling and sealing testing. The assembly and testing functions are integrated on a workbench to avoid manual handling and placement, and improve the production efficiency of assembly and testing operations.

DETAILED DESCRIPTION

[0026] In order to make the purpose, technical scheme and advantages of the present invention more clearly understood, the present invention is described and illustrated below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention. Based on the embodiments provided by the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the present invention.

[0027] Obviously, the drawings described below are only some examples or embodiments of the present invention. For ordinary technicians in this field, the present invention can also be applied to other similar scenarios based on these drawings without creative work. In addition, it can also be understood that although the efforts made in this development process may be complicated and lengthy, for ordinary technicians in this field related to the content disclosed by the present invention, some changes in design, manufacturing or production based on the technical content disclosed by the present invention are just conventional technical means, and should not be understood as insufficient content disclosed by the present invention.

[0028] However, unnecessary detailed descriptions may be omitted. For example, detailed descriptions of well-known matters and repeated descriptions of substantially the same structures may be omitted. This is to avoid the following description from becoming unnecessarily lengthy and to facilitate understanding by those skilled in the art. In addition, the drawings and the following description are provided to enable those skilled in the art to fully understand the present invention and are not intended to limit the subject matter described in the claims.

[0029] See also Figure 1-Figure 2As shown, in an embodiment of the present invention, an expansion tank assembly test integrated workbench includes a workbench frame 1 and a turning table 2. The workbench frame 1 includes a profile frame 11 and a driving mechanism 12. The turning table 2 is rotatably connected to the profile frame 11, and the driving mechanism 12 is used to drive the turning table 2 to rotate.

[0030] The workbench frame 1 is assembled from metal profiles and is a rigid structure as a whole. It can bear the weight of the turning table 2 and the weight of the profile frame 11. A handrail is installed on one side of the profile frame 11, and the bottom is equipped with a pulley to quickly adjust the position of the workbench. A leakage tray 14 is installed below the profile frame 11. The leakage tray 14 is located directly below the turning table 2 and is used to receive liquid that may drip during the production and testing of the expansion tank. The leakage valve 15 is installed at the bottom of the leakage tray 14 to discharge the collected liquid.

[0031] The turning table 2 is composed of a profile frame 21, a static fixed seat 22, a movable fixed seat 23 and a connecting shaft 24. The profile frame 21 is connected to the bearing seats 13 on both sides of the workbench frame 1 through the connecting shafts 24 on both sides, and the turning table 2 is driven to rotate by the driving mechanism 12. When the movable fixed seat 23 moves toward the static fixed seat 22, the step chamfer of the movable fixed seat 23 clamps the bottom plate of the expansion water tank, and when the movable fixed seat 23 moves away from the static fixed seat 22, the step chamfer of the movable fixed seat 23 leaves the bottom plate of the expansion water tank, so that the expansion water tank can be easily disassembled and installed.

[0032] The connecting shaft 24 is driven by a turning motor, thereby driving the turning table 2 to rotate to change the placement state of the water tank.

[0033] See also Figure 2 and Figure 3 As shown, the movable fixing seat 23 has a built-in pressure sensor 236. When the bottom plate of the expansion water tank is inserted into or leaves the step structure, a control signal is output to start or stop the movement of the movable fixing seat 23.

[0034] An infrared sensor is set in the turning table 2, and a sensing point is set on the profile frame 11. The sensing state of the infrared sensor and the sensing point is used to determine whether the turning table 2 is in a horizontal position or a vertical position. When the corresponding position is reached, the driving mechanism 12 is controlled to stop, thereby realizing precise adjustment of the rotation position of the turning table 2.

[0035] See also Figure 2-Figure 4As shown, the movable fixing seat 23 includes a movable fixing plate 231, a movable motor 232, a gear 233, a rack 234 and a sliding connection block 235. When the turning table 2 is in a horizontal position to install the expansion water tank, the expansion water tank is placed on the profile frame 21, and one side of the expansion water tank is inserted into the static fixing seat 22. At this time, the movable motor 232 is started to drive the gear 233 to rotate and move relative to the rack 234 under meshing action, and at the same time, the movable fixing seat 23 is driven to slide on the profile frame 21, so that the other side of the expansion water tank is inserted into the movable fixing seat 23.

[0036] The stationary fixed seat 22 is rigidly connected to the profile frame 21 and cannot be moved, and the movable fixed seat 23 is connected to the profile frame 21 through the sliding connection block 235. The profile inner cavity of the profile frame 21 is provided with a rolling bearing 237, and the convex shaft 235 on the sliding connection block is clamped into the inner ring of the rolling bearing 237. The outer ring of the rolling bearing 237 is matched with the profile inner cavity of the profile frame 21 to ensure that the outer ring of the rolling bearing 237 can roll in the profile inner cavity and prevent the movable fixed seat 23 from being separated from the profile frame 21.

[0037] The turning table 2 further includes a stop profile 26, which is fixedly connected to the profile frame 21 and has a structure protruding relative to the profile frame 21. The movable fixing seat 23 and the static fixing seat 22 can limit the expansion water tank in the axial direction of the rotating shaft of the turning table 2, but lack a limiting structure in the radial direction of the rotating shaft. The stop profile 26 can limit the expansion water tank from sliding on the profile frame 21 along the length direction of the movable fixing seat 23, thereby improving the stability of the expansion water tank when the turning table 2 is turned over.

[0038] For further information, see Figure 1-Figure 3 , Figure 5 As shown, a fall arrester 25 is provided on the connecting shaft 24. The main function of the fall arrester 25 is to automatically intervene and lock when the turning table 2 may cause one side to rotate and fall rapidly due to unexpected circumstances (such as failure of the driving mechanism 12, external force impact or loss of control caused by overload), thereby preventing the turning table 2 from rotating freely and hitting by inertia, thereby ensuring the safety of the equipment and operators.

[0039] The anti-fall device 25 includes a ring gear 251, a rotating pin 252 and a locking wheel 253. The ring gear 251 is fixed to the inner wall of the bearing seat 13 and does not participate in the normal flipping operation. The rotating pin 252 is fixedly connected to the connecting shaft 24 and moves with the rotation of the flip table 2. The locking wheel 253 is sleeved on the outer periphery of the rotating pin 252. The locking wheel 253 has teeth that can mesh with the ring gear 251. It can rotate synchronously under the drive of the rotating pin 252 and maintain a certain gap between the rotating pin 252 to ensure that it will not mesh with the ring gear 251 during normal operation. When the flip table 2 is operating normally, the locking wheel 253 remains in a free state and only rotates with the rotating pin 252, without exerting additional influence on the flip table 2. When the flip table 2 accidentally falls due to external force or failure of the driving mechanism 12, the anti-fall device 25 quickly intervenes. At this time, when the connecting shaft 24 rotates rapidly, the locking wheel 253 is offset due to centrifugal force and inertia, and approaches the ring gear 251. The locking wheel 253 is designed as an eccentric structure, and its eccentric part quickly meshes with the gear ring 251 to form a blocking effect. The meshing of the locking wheel 253 prevents the further movement of the rotating pin 252, thereby limiting the rotation of the connecting shaft 24, and the turning table 2 is quickly locked in the current position.

[0040] The workbench can have two turning tables 2 arranged side by side. When the expansion water tank on one of the turning tables 2 is in a vertical state for testing, the operator can operate the control button to put the other turning table 2 in a horizontal state for assembly work. The two workstations operate in a cycle, which can shorten the waiting time and further speed up the production speed.

[0041] The specific usage of this embodiment is as follows:

[0042] When the operator starts the operation, he operates the control button to put both the turning tables 2 in a horizontal state, and places an expansion water tank on the profile frame 21 of one of the turning tables 2, so that the bottom plate of the expansion water tank is stuck in the step structure of the static fixing seat 22. The operator operates the control button to slide the movable fixing seat 23 toward the static fixing seat 22 until the built-in pressure sensor 236 of the movable fixing seat 23 contacts the bottom plate of the expansion water tank, at which time the movable motor 232 stops operating, and the expansion water tank is fastened to the turning table 2 by the static fixing seat 22 and the movable fixing seat 23.

[0043] The expansion tank is in a horizontal state, and the operator begins to assemble accessories such as quick connectors, liquid level switches and pressure relief valves. After the assembly is completed, the control button is operated, and the drive mechanism 12 starts to operate, so that the turning table 2 rotates. When the turning table 2 drives the expansion tank to rotate to a vertical state, the infrared sensor installed on the turning table 2 senses the through hole on the profile frame 11, and the drive mechanism 12 stops operating. The expansion tank is in a vertical state, and the operator begins to add coolant to simulate the operating environment of the expansion tank after loading and conduct related tests such as sealing test, liquid level switch test and pressure relief test. After the test is completed, the operator operates the control button, and the drive mechanism 12 starts to operate, so that the turning table 2 rotates to a horizontal state. The infrared sensor installed on the turning table 2 senses the through hole on the horizontal auxiliary positioning rod, and the drive mechanism 12 stops operating. Further operate the control system, the movable motor 232 starts to operate, and the movable fixed seat 23 starts to slide away from the static fixed seat 22. After reaching the predetermined stroke, the movable motor 232 stops operating. At this time, the operator can remove the expansion tank, and the assembly and test operation process is completed.

[0044] It should be noted that the present invention is not limited to the above-mentioned embodiments. The above-mentioned embodiments are only examples, and the embodiments having the same structure as the technical idea and exerting the same effect within the scope of the technical solution of the present invention are all included in the technical scope of the present invention. In addition, without departing from the scope of the main purpose of the present invention, various modifications that can be thought of by those skilled in the art to the embodiments and other methods of combining some of the constituent elements in the embodiments are also included in the scope of the present invention.
