Description

Technical Field

[0001] The utility model relates to the field of linear motors, in particular to a linear motor positioning device. Background Art

[0002] Linear motors are a type of direct drive technology that, unlike rotary motors, does not require the use of rotating parts such as screws and pulleys to convert into linear motion.

[0003] The Chinese patent publication number: CN 216121992 U records a "linear motor positioning device", which is to set the lower end of the fixed block to a level higher than the bottom end of the base.

[0004] The horizontal height is low, so that when the base is fixed, a gap can be left between the base and the mounting plate to increase the contact area between the lower surface of the base and the air, thereby improving the heat dissipation effect of the base. At the same time, a heat dissipation groove is opened on the mounting plate, and a heat dissipation fan is arranged under the heat dissipation groove. The heat dissipation of the motor body base is accelerated by air cooling to avoid heat accumulation on the base to affect the motor body.

[0005] However, there are still the following defects and shortcomings in the application process:

[0006] The heat dissipation fan is installed on the mounting plate bracket. Although the flow of air can be accelerated to achieve heat dissipation when the fan is working, the air holes will be blocked by various impurities over a long period of time, which will affect the normal circulation of air flow and the heat dissipation effect of the entire device.

[0007] Therefore, it is necessary to provide a new linear motor positioning device to solve the above technical problems. Utility Model Content

One end of the transmission shaft penetrates the positioning seat and is connected through a bearing, while the other end penetrates the filter screen and is rotatably connected thereto. The scraper is attached to the outer wall of the filter screen.

[0018] Preferably, the manual drive assembly comprises a knob, a spring is sleeved on the outside of the knob, a rubber baffle is fixed to the knob, a driving gear is fixed to one end of the knob, and a driven gear is arranged on the side of the driving gear.

It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0033] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0034] See also Figures 1 to 4 The utility model provides a linear motor positioning device, which includes a mounting plate 1, a through hole 2 is provided on the mounting plate 1, and a fan 3 is arranged inside the through hole 2, and further includes:

[0035] The shell seat 4 is bolted to the lower end of the mounting plate 1 and covers the lower end opening of the through hole 2. An air inlet pipe 5 is welded to the side of the shell seat 4. A hemispherical filter screen 6 is fixed to one end of the air inlet pipe 5.

[0036] The cleaning component 7 is installed inside the housing 4 and is also attached to the outer wall of the filter 6, and scrapes off impurities attached to the outside of the filter 6 by rotating;

[0037] The manual drive assembly 10 is installed inside the housing 4 and is also fixed to the cleaning assembly 7;

[0038] The cleaning component 7 can be driven pneumatically or by a manual driving component 10 .

[0039] It should be noted that: in the device, a housing seat 4 is fixed at the lower end of the mounting plate 1, and an air inlet pipe 5 is installed on the housing seat 4. Therefore, when the fan 3 is working, the airflow enters the housing seat 4 along the air inlet pipe 5, and then passes through the through-hole 2 to achieve heat dissipation of the motor;

[0040] It should also be noted that: a hemispherical filter screen 6 is arranged at the outer end of the air inlet pipe 5, and a cleaning component 7 is also installed inside the housing 4. The cleaning component 7 can be pneumatically driven, that is, when the airflow passes through the air inlet pipe 5, it can drive the cleaning component 7 to rotate. The cleaning component 7 in the rotating state can scrape off the impurities attached to the filter screen 6, thereby cleaning the filter screen 6 to ensure the normal circulation of the airflow;

[0041] It should also be noted that a manual drive component 10 is also provided on the shell base 4, and the manual drive component 10 can also drive the cleaning component 7 to rotate, so as to clean the filter 6. The cleaning component 7 has a variety of driving modes, so it can be adjusted according to actual usage to avoid clogging of the filter 6.

[0042] In the embodiments of the present invention, please refer to Figures 1 to 3 The cleaning assembly 7 includes a transmission shaft 71, on which a coaxial impeller 72 is fixed, and one end of the transmission shaft 71 is also fixed with a plurality of scrapers 73 distributed in an annular shape;

[0043] Among them, a positioning seat 8 is also welded inside the shell seat 4;

[0044] The transmission shaft 71 coaxially penetrates the air intake pipe 5, and the impeller 72 is located inside the air intake pipe 5. One end of the transmission shaft 71 penetrates the positioning seat 8 and is connected through the bearing 9, while the other end penetrates the filter screen 6 and is rotatably connected thereto. The scraper 73 is attached to the outer wall of the filter screen 6.

[0045] It should be noted that when the airflow flows through the inside of the air inlet pipe 5 , it will generate a force on the impeller 72 , thereby driving it to rotate. When the impeller 72 rotates, it can drive the scraper 73 to rotate through the transmission shaft 71 , so that the scraper 73 is used to clean the filter screen 6 .

[0046] In the embodiments of the present invention, please refer to Figure 1 , Figure 2 and Figure 4 The manual drive assembly 10 includes a knob 101, a spring 102 is sleeved on the outside of the knob 101, a rubber baffle 103 is fixed on the knob 101, a driving gear 104 is fixed on one end of the knob 101, and a driven gear 105 is also arranged on the side of the driving gear 104;

[0047] The knob 101 penetrates the housing seat 4 and is rotatably connected thereto, and the knob 101 can move up and down relative to the housing seat 4, while the spring 102 presses against the lower end of the housing seat 4;

[0048] The driven gear 105 is coaxially fixed to the end of the transmission shaft 71;

[0049] Meanwhile, when the knob 101 moves downward to the lowest position, the driving gear 104 does not contact the driven gear 105 , and when it moves upward to the highest position, the driving gear 104 can mesh with the driven gear 105 for transmission.

[0050] It should be noted that: under normal conditions, the knob 101 is at the lowest position due to the elastic force of the spring 102. At this time, the rubber baffle 103 is attached to the bottom of the housing 4 to play a sealing role. At the same time, the driving gear 104 and the driven gear 105 are not in contact. Therefore, the rotation of the cleaning component 7 is not affected by the manual driving component 10, and the force generated by the airflow can be used as the power.

[0051] When the manual drive assembly 10 is used, the knob 101 is pressed upward so that the driving gear 104 can mesh with the driven gear 105. At this time, when the knob 101 is turned, the transmission shaft 71 can be driven to rotate through the gear transmission, thereby cleaning the filter screen 6.

[0052] The circuits and controls involved in the present invention are all prior art and will not be described in detail here.

[0053] The above are only embodiments of the present invention, and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
