Description

Technical Field

[0001] This utility model belongs to the field of speed reducer parts processing technology, specifically relating to a locking structure for precision machining of the housing of a micro cycloidal pinwheel planetary speed reducer. Background Technology

[0002] As the demands of different application scenarios and operating conditions increase, the size of traditional cycloidal pinwheel reducers cannot be adapted to all scenarios and operating conditions, which necessitates the development of miniature cycloidal pinwheel planetary reducers with smaller dimensions.

[0003] Similarly, the size of small-sized components of miniature cycloidal pinwheel planetary reducers, such as the housing, is also correspondingly smaller. The finishing process of the housing involves steps such as grinding, drilling, or cutting. These steps require the use of tooling fixtures to hold the housing blank in place, thus achieving precise finishing.

[0004] Current tooling fixtures are generally suitable for fixing large-sized machine housing parts, but not for small-sized machine housing parts.

[0005] Therefore, based on the above problems, this utility model provides a locking structure for precision machining of the housing of a micro cycloidal pinwheel planetary reducer. Utility Model Content

[0021] Example 1

[0022] like Figure 1 and Figure 2The locking structure of the precision-machined housing of the miniature cycloidal pinwheel planetary reducer shown includes a detachable platform 100 and a PLC controller 113.

[0023] The detachable platform 100 has hydraulic cylinder seats 101 and vertical U-shaped plates 108 on both end faces.

[0024] A horizontal hydraulic cylinder 102 is mounted on the hydraulic cylinder base 101.

[0025] A transition connecting plate 103 is provided on the horizontal hydraulic cylinder 102.

[0026] A pressure bar 104 is provided on one end face of the transition connecting plate 103.

[0027] A connecting block 105 is provided on one end face of the pressure rod 104.

[0028] An arc-shaped dynamic pressure plate 106 is provided on the connecting block 105.

[0029] A pressure sensor mounting groove 109 is provided within the symmetrical center line of the vertical U-shaped plate 108.

[0030] An open-type limiting sleeve 110 is provided on one side of the vertical U-shaped plate 108, located on the surface of the pressure sensor mounting groove 109.

[0031] A pressure sensor 115 is installed in the pressure sensor mounting slot 109.

[0032] The open-type limiting sleeve 110 is equipped with a flexible padding block 111.

[0033] An arc-shaped pressure plate 112 is provided on the flexible pad pressure block 111;

[0034] The horizontal hydraulic cylinder 102 and the pressure sensor 115 are respectively connected to the PLC controller 113.

[0035] The working principle is as follows: the horizontal hydraulic cylinder 102 is the power source; the pressure sensor 115 feeds back the pressure value to the PLC controller 113; the PLC controller 113 presets the maximum pressure value (to prevent overpressure from deforming the housing 107 under the premise of clamping) and matches the pressure sensor 115 to control the horizontal hydraulic cylinder 102.

[0036] (1) Place the housing 107 on the surface of the detachable table 100 and place it on one side of the arc-shaped pressure plate 112;

[0037] (2) The horizontal hydraulic cylinder 102 is started by using the PLC controller 113. The horizontal hydraulic cylinder 102 pushes the arc-shaped moving pressure plate 106 to move towards the side close to the arc-shaped fixed pressure plate 112 through the pressure rod 104 and the connecting block 105 until it cooperates with the arc-shaped fixed pressure plate 112 to press the machine housing 107. The horizontal hydraulic cylinder 102 is stopped by using the PLC controller 113 and the current action is maintained.

[0038] During the pressing process, the flexible pad 111 on one side of the arc-shaped pressure plate 112 applies pressure to the pressure sensor 115. The pressure sensor 115 feeds back the pressure signal to the PLC controller 113, and the PLC controller 113 performs precise control of the horizontal hydraulic cylinder 102 according to the preset information.

[0039] Example 2

[0040] Based on Example 1, such as Figure 3 and Figure 4 The locking structure of the precision-machined housing of the miniature cycloidal pinwheel planetary reducer shown includes waist-shaped through grooves 116 symmetrically arranged in the middle of both sides of the vertical U-shaped plate 108, arc-shaped pressure plate screw grooves 117 respectively arranged in the middle of both sides of the arc-shaped pressure plate 112, and a limiting slide rod 118 that passes through the waist-shaped through grooves 116 and is fixed to the arc-shaped pressure plate 112 through the arc-shaped pressure plate screw grooves 117.

[0041] The arc-shaped pressure plate 112 can be horizontally mounted on the vertical U-shaped plate 108 through the matching waist-shaped through groove 116, arc-shaped pressure plate screw groove 117, and limiting slide rod 118. This facilitates the clamping action control of the housing 107 and improves the precision machining efficiency of the housing 107.

[0042] Example 3

[0043] Based on Embodiment 2, the locking structure of the micro cycloidal pinwheel planetary reducer housing precision machined further includes locking nuts 119 respectively set on the limiting slide rod 118 and located on both sides of the waist-shaped through groove 116, and the connection surface between the limiting slide rod 118 and the locking nut 119 is set as a threaded structure.

[0044] After the housing 107 is clamped, the arc-shaped pressure plate 112 can be fixed in position by locking nut 119 and limiting slide bar 118 to prevent the arc-shaped pressure plate 112 from shifting due to vibration during the finishing process, which would lead to unstable fixation.

[0045] Example 4

[0046] Based on Embodiment 1, Embodiment 2, or Embodiment 3, the locking structure of the precision-machined housing of the micro cycloidal pinwheel planetary reducer further includes a warning component 114 connected to the PLC controller 113; wherein, the warning component 114 includes, but is not limited to, a strobe light.

[0047] When overvoltage occurs (causing potential deformation of housing 107), the PLC controller 113 controls the early warning component 114 to issue an early warning. At the same time, the operator inspects housing 107 to prevent deformed housing 107 from being mixed into the finished product.

[0048] Furthermore, when the warning component 114 is detected, the PLC controller 113 controls the horizontal hydraulic cylinder 102 to perform a timely reset action, that is, the horizontal hydraulic cylinder 102 drives the arc-shaped moving pressure plate 106 to move away from the arc-shaped fixed pressure plate 112 through the pressure rod 104 and the connecting block 105.

[0049] In the locking structure of the precision-machined housing of the miniature cycloidal pinwheel planetary reducer of this structure, the detachable platform 100, the horizontal hydraulic cylinder 102, the PLC controller 113, the early warning component 114, and the pressure sensor 115 are all conventional components. These will not be elaborated upon in this application.

[0050] It should be noted that, in this document, terms such as "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0051] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
