[0003] After searching, Chinese patent CN205506384U discloses a rodless cylinder testing device. The device includes an air source, a filter, a pressure reducing valve, a dust cleaning valve, a controller, a slide rail and a bracket. The air source is connected to the filter, the pressure reducing valve and the dust cleaning valve in sequence through an air pipe. The dust cleaning valve is connected to the air ports at both ends of the rodless cylinder to be tested through two air pipes. The dust cleaning valve is also connected to the controller through a wiring harness. The two ends of the rodless cylinder are mounted on two brackets, wherein one bracket is fixed to one end of the slide rail and the other bracket is fixed to a slider that cooperates with the slide rail.

[0029] Example:

[0030] This embodiment provides a multifunctional magnetic coupling rodless cylinder testing device, which can perform visual comparative tests on durability and stability for different brands, different loads, various usage environments (dust particles), and other working conditions.

[0031] like Figures 1 to 3As shown, the test device provided in this embodiment includes a test box 1, a first air pipe 2, a rodless cylinder fixing frame 3, and a plate-like component 4 connected to the interior of the test box 1. The plate-like component 4 divides the test box 1 into an upper box body 11 and a lower box body 12. The rodless cylinder fixing frame 3 includes multiple groups of limiting areas and is fixedly connected to the inner opposite side walls of the upper box body 11. The pre-acquired magnetic rodless cylinder 5 to be tested is placed in the corresponding limiting area. The interior of the lower box body 12 includes a distribution cylinder 121, a quick-connect air pipe 122, a second air pipe 123, a two-position five-way valve 124 and a third air pipe 125 connected in sequence. One end of the first air pipe 2 passes through the side wall of the lower box body 12 and is connected to the distribution cylinder 121. The third air pipe 125 passes through the plate-like component 4 and is connected to the end of the magnetic rodless cylinder 5 to be tested.

[0032] like Figure 1 As shown, the test device provided in this embodiment further includes a filter 6, a pressure reducing valve 7, a signal line 8, and a control box 9 located outside the test box 1. One end of the filter 6 is connected to the external air source, and the other end is connected to the pressure reducing valve 7. The other end of the pressure reducing valve 7 is connected to the other end of the first air pipe 2. The two-position five-way valve 124 is connected to the control box 9 via the signal line 8. As can be seen, the test device provided in this embodiment is generally divided into the air circuit and the circuit part:

[0033] Gas circuit: The external gas source passes through the filter 6 and the pressure reducing valve 7 and enters the test box 1 through the first gas pipe 2 to connect to the distribution cylinder 121;

[0034] Circuit part: such as Figure 2 As shown, the two-position five-way valve 124 in the lower box body 12 is connected to the control box 9 via the signal line 8.

[0035] like Figure 2 and Figure 3 As shown, the interior of the upper housing 11 also includes multiple first nozzles 111, multiple second nozzles 112, and nozzle holders 113. The number of nozzle holders 113 corresponds to the number of first nozzles 11. The nozzle holders 113 are fixedly connected to the inner wall of the upper housing 11. The first nozzles 111 are fixedly connected to the nozzle holders 113. The second nozzles 112 are fixedly connected to one side of the plate-like element 4 located on the upper housing 11. The first nozzles 111 and the second nozzles 112 are respectively connected to quick-connect air pipes 122. The magnetic rodless cylinder 5 to be tested has a slider 51, under which a counterweight can be installed.

[0036] The distribution cylinder 121 uses the quick-connect air pipe 122 to send part of the gas to the first nozzle 111 and the second nozzle 112, which can realize continuous jetting of the nozzles; the other part of the gas is sent to the two-position five-way valve 124 through the second air pipe 123, and the two-position five-way valve 124 is connected to the magnetic rodless cylinder 5 to be tested.

[0037] Among them, the first nozzle 111 and the second nozzle 112 are both installed in the upper box 11, blowing air downward and upward at the same time, which can quickly lift dust and other particulate matter and spread them in the test box 1. The first nozzle 111 blows air downward and is installed on the nozzle fixing bracket 113, and the second nozzle 112 blows air upward and is installed on the plate-like element 4. The nozzle angle can be rotated to meet the use conditions, and air is directly supplied through the quick-plug air pipe 122 inside the lower box 12; the magnetic rodless cylinder 5 to be tested is installed on the rodless cylinder fixing bracket 3, and a counterweight test can be performed at the lower end of the slider 51 of the magnetic rodless cylinder 5 to be tested. In the figure, there are two rodless cylinder fixing brackets 3, which are symmetrically installed on the opposite inner walls of the upper box. Each rodless cylinder fixing bracket 3 has three limiting areas for fixing three magnetic rodless cylinders 5 to be tested.

[0038] like Figure 4 As shown, the entire test box 1 is composed of an aluminum profile frame 13 and a stainless steel cover plate 14. It has a simple structure, is economical and lightweight, and is easy to assemble. It has a double door design at the front and back ends. The four sides and the top are assembled with transparent acrylic cover plates 114 and sponge strips, which makes it easy to observe the test conditions. Handles 15 are provided on both sides for easy transportation.

[0039] The upper box body 11 is supported by an aluminum profile frame 13, and is assembled on all sides and the top by transparent acrylic sealing panels 114 and sponge strips; the lower box body 12 is supported by an aluminum profile frame 13, and is assembled on all sides and the bottom by stainless steel sealing panels 14, wherein the opposite side walls are both openable and closable sealing panels 126, forming a double-door structure.

[0040] Furthermore, the interior of the lower box 12 further includes a three-way valve, one end of which is connected to the air outlet of the two-position five-way valve 124, and the other end is connected to the third air pipe 125. The setting of the three-way valve can realize the simultaneous testing of multiple rodless cylinders.

[0041] The working principle of the testing device provided in this embodiment is as follows:

[0042] 1. The external air source enters the distribution cylinder 121 through the first air pipe 2 after passing through the filter 6 and the pressure reducing valve 7. The air outlet of the distribution cylinder 121 is connected to the first nozzle 111, the second nozzle 112 and the two-position five-way valve 124. The air outlet of the two-position five-way valve 124 is connected to the two ends of the magnetic rodless cylinder 5 to be tested, which is fixed on the rodless cylinder fixing frame 3. When multiple magnetic rodless cylinders 5 to be tested are tested at the same time, the air outlet of the two-position five-way valve 124 can be divided by a connector (such as a three-way valve) to connect multiple magnetic rodless cylinders 5 to be tested;

[0043] 2. During the test, the control box 9 (including the switching power supply, control board, relay board, etc.) can be used to control the power on and off of the two-position five-way valve 124 to achieve the reciprocating motion of the slider 51 of the rodless cylinder and its load and its motion frequency.

[0044] The aforementioned testing device has at least the following advantages:

[0045] 1. Simple structure, easy to process and assemble, saving costs;

[0046] 2. Wide test range, applicable to multiple cylinders, loads and environments, meeting various test conditions;

[0047] 3. Simple debugging, convenient replacement and easy observation.

[0048] The above describes in detail the preferred embodiments of the present invention. It should be understood that those skilled in the art can make numerous modifications and variations based on the concepts of the present invention without inventive effort. Therefore, any technical solutions that can be derived by those skilled in the art based on the concepts of the present invention through logical analysis, reasoning, or limited experimentation based on the existing technology should be within the scope of protection defined by the claims.
