Description

Technical Field

[0001] This utility model relates to the field of automotive parts manufacturing technology, and in particular to an automatic rotating frame and a high and low temperature test chamber. Background Technology

[0002] In the automotive parts manufacturing process, parts testing is one of the steps.

[0003] A search revealed a prior art rotating high and low temperature test chamber (publication number: CN106989760A), comprising a sealed test chamber, a heating system, a cooling system, a temperature sensor, and a controller. The heating system includes an electric heating coil, and the cooling system includes an air-cooled condenser. The chamber is characterized by further comprising a frame, a transverse rotating shaft, an inclined rotating shaft, gears, transmission gears, a drive mechanism, and a right-angle base. The two side walls of the test chamber are respectively connected to the inner side walls of the frame via transverse rotating shafts, with the inner end of the transverse rotating shaft penetrating the inner side walls of the test chamber. The top and bottom surfaces of the frame are respectively connected to the vertical and horizontal surfaces of the right-angle base via inclined rotating shafts.

[0004] In existing technologies, the accuracy of workpiece motion is achieved through movement in two axes, but the speed of movement is not adjustable. The only way to achieve this is to increase the speed of the motor. However, this is not feasible for adjusting the linear speed of the workpiece while maintaining the angular velocity, and thus lacks the ability to control the variable of the workpiece for experimental detection. There is room for optimization.

[0005] Therefore, we propose an automatic rotating frame and a high and low temperature test chamber. Utility Model Content

[0007] To achieve the above objectives, this utility model adopts the following technical solution: an automatic rotating frame, comprising: A vertical shaft is provided below which a motor is provided to drive the vertical shaft to rotate. The vertical shaft is fixedly connected to the output shaft of the motor. A first rotating body is fixedly installed at the upper end of the vertical shaft. A rotatable crossbar is movably installed on the first rotating body. A limiting structure is provided on a crossbar for mounting workpieces and enabling the crossbar to rotate. The limiting structure includes a slide, a horizontal shaft, rubber wheels, extrusion blocks, and positioning holes. A horizontal shaft is fixedly installed at each end of the crossbar, and the horizontal shaft is rotatably connected to a first rotating body. A rubber wheel is fixedly installed at the end of each horizontal shaft. Several adjustable extrusion blocks are provided below the rubber wheels, and the rubber wheels can be tangent to the extrusion blocks. Several positioning holes are opened at the bottom of the crossbar, and fasteners are provided at the bottom of the slide. The fasteners can be inserted into the positioning holes to limit the movement of the slide. An adjustment component is located below the extrusion block to adjust its position.

[0008] In a preferred embodiment of the present invention, the first rotating body forms a C-shaped ring with an open top, the vertical shaft is fixedly installed directly below the first rotating body, the circumferential surface of the first rotating body is provided with a shaft hole, and the horizontal shaft is rotatably disposed in the shaft hole.

[0009] In a preferred embodiment of this utility model, the crossbar is a rectangular bar, the slide is a rectangular block, the slide has a rectangular groove that fits the crossbar through it, the crossbar passes through the rectangular groove, and a mounting base for mounting workpieces is fixedly installed on the top of the slide.

[0010] In a preferred embodiment of this utility model, the extrusion block is a block with an arc-shaped horizontal cross section, and an integrally formed extension rod is provided at the end of the extrusion block, the extension rod extending obliquely downward towards the extrusion block.

[0011] In a preferred embodiment of this utility model, the adjustment assembly includes a base, an adjustment seat, and a support rod. The base is fixedly disposed below the first rotating body, and several adjustment seats are slidably disposed on the base. A support rod is fixedly installed on each adjustment seat, and the push block is fixedly connected to the upper end of the support rod.

A vertical shaft is rotatably connected to the test chamber body. A motor is fixedly installed on the outer bottom surface of the test chamber body, and a base is fixedly installed on the inner bottom surface of the vertical shaft.

[0014] This utility model provides an automatic rotating frame and a high and low temperature test chamber. It has the following beneficial effects: 1. This automatic rotating frame and high / low temperature test chamber, by connecting a motor to a power source and a control switch, drives a vertical shaft to rotate. The vertical shaft drives a first rotating body to perform circular motion, while the first rotating body moves horizontally along a horizontal bar. This pushes a slide table to slide radially along the horizontal bar, thereby adjusting the horizontal movement radius of the workpiece on the slide table, i.e., the magnitude of its linear velocity. Simultaneously, during the movement of the first rotating body, a rubber wheel can squeeze a pushing block, causing the rubber wheel and the horizontal shaft to rotate through friction. The horizontal shaft rotates around its axis, causing the horizontal bar and the slide table to move along another axis, thus enabling the detection of the workpiece under two-axis motion. The workpieces are mainly automotive parts, such as sensors. It more realistically simulates the stability of sensors under vehicle driving conditions, resulting in higher detection accuracy. The overall structure is simple, requiring only one motor drive. The linear speed of the detection is adjustable. After adjusting the position of the slide, the slide is locked by rotating the fasteners. Taking bolts as an example, the bolts are inserted into the corresponding positioning holes. Adjusting and fixing the slide is simple and quick. The deformable rubber wheel is guided by the inclined extension section on the side of the extrusion block, ensuring that the rubber wheel can roll smoothly to the top of the extrusion block and then be pushed by the extrusion block to form a circular motion.

[0015] 2. This automatic rotating frame and high and low temperature test chamber, by pushing the adjusting seat to slide along the base, the adjusting seat drives the support rod and the extrusion block on its top to move. Several adjusting seats and support rods are set on the base. By adjusting the distance between two adjacent extrusion blocks, the period of contact between the rubber wheel and the extrusion block can be adjusted, realizing the intermittent pushing of the crossbar, further improving the controllability of the movement adjustment of the workpiece on the slide. Secondly, after adjusting the position of the adjusting seat, the fastener, taking bolts as an example, is threadedly connected to the adjusting seat. The bolts are inserted into the thrust hole to realize the locking and limiting of the base. The adjustment and operation are simple and quick. Attached Figure Description

[0018] An automatic rotating frame and a high and low temperature test chamber, such as Figure 3 As shown, it includes: A vertical shaft 10 is provided below the vertical shaft 10, and a motor is provided to drive the vertical shaft 10 to rotate. The vertical shaft 10 is fixedly connected to the output shaft of the motor. A first rotating body 11 is fixedly installed at the upper end of the vertical shaft 10, and a rotatable crossbar 12 is movably installed on the first rotating body 11. like Figure 3 , Figure 4 and Figure 5 As shown, a limiting structure is installed on the crossbar 12 for mounting workpieces and enabling the crossbar 12 to rotate. The limiting structure includes a slide table 13, a horizontal shaft 14, rubber wheels 15, extrusion blocks 16, and positioning holes 17. A horizontal shaft 14 is fixedly installed at each end of the crossbar 12, and the horizontal shaft 14 is rotatably connected to the first rotating body 11. A rubber wheel 15 is fixedly installed at the end of each horizontal shaft 14. Several adjustable extrusion blocks 16 are provided below the rubber wheels 15, and the rubber wheels 15 can be tangent to the extrusion blocks 16. Several positioning holes 17 are opened at the bottom of the crossbar 12, and fasteners are provided at the bottom of the slide table 13, which can be inserted into the positioning holes. The slide 13 is limited within 17. The first rotating body 11 forms a C-shaped ring with an open top. The vertical shaft 10 is fixedly installed directly below the first rotating body 11. The circumferential surface of the first rotating body 11 has a shaft hole. The horizontal shaft 14 is rotatably installed in the shaft hole. The horizontal bar 12 is a rectangular bar. The slide 13 is a rectangular block. The slide 13 has a rectangular groove that is clearance-fitted with the horizontal bar 12. The horizontal bar 12 passes through the rectangular groove. The top of the slide 13 is fixedly installed with a mounting seat for installing the workpiece. The extrusion block 16 is a block with an arc-shaped horizontal cross section. The end of the extrusion block 16 is provided with an integrally formed extension rod. The extension rod extends obliquely downward towards the extrusion block 16. In this scheme, by connecting the motor to the power supply and control switch, the motor drives the vertical shaft 10 to rotate, which in turn drives the first rotating body 11 to perform circular motion. The first rotating body 11 carries the horizontal bar 12 to move horizontally, pushing the slide table 13 to slide radially along the horizontal bar 12. This allows adjustment of the horizontal movement radius of the workpiece on the slide table 13, i.e., the magnitude of its linear velocity. Simultaneously, during the movement of the first rotating body 11, the rubber wheel 15 can squeeze the pushing block 16, causing the rubber wheel 15 and the horizontal shaft 14 to rotate through friction. The horizontal shaft 14 rotates around its axis, causing the horizontal bar 12 and the slide table 13 to move along another axis, thus achieving the detection of the workpiece under two-axis motion. The workpieces being tested are mainly automotive parts, such as sensors. This method more realistically simulates the stability of sensors under vehicle driving conditions, resulting in higher detection accuracy. The overall structure is simple, requiring only one motor drive. The linear speed of the detection is adjustable. After adjusting the position of the slide 13, the slide 13 is locked by rotating the fastener (taking bolts as an example) and inserting the bolts into the corresponding positioning holes 17. Adjusting and fixing the slide 13 is simple and quick. The deformable rubber wheel 15 is guided by the inclined extension section on the side of the push block 16, ensuring that the rubber wheel 15 can smoothly roll to the top of the push block 16 and then be pushed by the push block 16 to generate a circular motion.

[0019] like Figure 3 and Figure 4 As shown, the adjustment component is located below the extrusion block 16 to adjust the position of the extrusion block 16; The adjustment assembly includes a base 20, an adjustment seat 21, and a support rod 22. The base 20 is fixedly disposed below the first rotating body 11. Several adjustment seats 21 are slidably disposed on the base 20. A support rod 22 is fixedly installed on each adjustment seat 21. The push block 16 is fixedly connected to the upper end of the support rod 22. The base 20 is an annular ring. Several thrust holes 23 are opened on the top of the base 20. Another fastener is provided on the adjustment seat 21. The fastener can be inserted into the thrust hole 23. An annular groove is opened on the outer circumferential surface of the base 20. An arc-shaped groove that fits the base 20 is opened at the lower end of the adjustment seat 21. A stop block is fixedly disposed on the side wall of the adjustment seat 21. The stop block is slidably disposed in the annular groove. As a supplementary explanation of the above scheme, by pushing the adjusting seat 21 to slide along the base 20, the adjusting seat 21 drives the support rod 22 and the extrusion block 16 on its top to move. The base 20 is provided with several adjusting seats 21 and support rods 22. By adjusting the distance between two adjacent extrusion blocks 16, the period of contact between the rubber wheel 15 and the extrusion block 16 can be adjusted, realizing the intermittent pushing of the crossbar 12, further improving the controllability of the movement adjustment of the workpiece on the slide table 13. Secondly, after adjusting the position of the adjusting seat 21, the fastener, taking the bolt as an example, is threadedly connected to the adjusting seat 21. The bolt is inserted into the thrust hole 23 to realize the locking and limiting of the base 20. The adjustment and operation are simple and quick.

[0020] like Figure 1 and Figure 2 As shown, a high and low temperature test chamber includes a test chamber body 30. The interior of the test chamber body 30 is hollow and forms a test cavity. A sealing door is hinged to the front wall of the test chamber body 30. All the aforementioned automatic rotating frames are provided inside the cavity of the test chamber body 30. A vertical shaft 10 is rotatably connected to the test chamber body 30. A motor is fixedly installed on the outer bottom surface of the test chamber body 30. A base 20 is fixedly installed on the inner bottom surface of the vertical shaft 10. Air boxes are provided on both sides of the test chamber body 30. Air ducts connecting the air boxes are fixedly installed inside the test chamber body 30. By connecting the two air boxes to air pumps, and the air pumps to an air source, which is air that has been heated or cooled, the high and low temperature durability test of the workpiece is achieved by sending cold or hot air into the test chamber body 30. Details are omitted here. By setting up the aforementioned automatic rotating frame, it is possible to detect the stability of the workpiece's two-axis motion direction, and also to adjust the linear velocity of one of the axes moving upwards. The whole structure is a mechanical structure, which is simple and highly stable, requiring only one motor as a power source.

[0021] The working principle of this utility model is as follows: The air duct connecting the air box is fixedly installed inside the test chamber body 30. By connecting the two air boxes to the air pumps respectively, and the air pumps to the air source, the air source is air that has been heated or cooled. By sending cold air or hot air into the test chamber body 30, the high and low temperature durability test of the workpiece can be achieved. The adjusting seat 21 is pushed to slide along the base 20, which in turn drives the support rod 22 and the top extrusion block 16 to move. Several adjusting seats 21 and support rods 22 are provided on the base 20. By adjusting the distance between two adjacent extrusion blocks 16, the contact period between the rubber wheel 15 and the extrusion block 16 can be adjusted. After adjusting the position of the slide 13, the slide 13 is locked by rotating the fastener (e.g., a bolt). The bolt is inserted into the corresponding positioning hole 17. Adjusting and fixing the slide 13 is simple and quick. The deformable rubber wheel 15 is guided by the inclined extension section beside the extrusion block 16, ensuring that the rubber wheel 15 can smoothly roll to the top of the extrusion block 16 and be extruded by the extrusion block 16. 6. The motor drives the vertical shaft 10 to rotate, which in turn drives the first rotating body 11 to rotate. The first rotating body 11 moves horizontally along the crossbar 12. By pushing the slide table 13 to slide radially along the crossbar 12, the horizontal movement radius of the workpiece on the slide table 13 can be adjusted, i.e., the linear velocity. At the same time, during the movement of the first rotating body 11, the rubber wheel 15 can squeeze the push block 16. Through friction, the rubber wheel 15 and the crossbar 14 rotate. The crossbar 14 rotates around its axis, causing the crossbar 12 and the slide table 13 to move on another axis. This enables the detection of the workpiece in two-axis motion, and the detection of the stability of the part in high and low temperature environments and in motion.
