Description

Technical Field

[0001] This application relates to the field of Mecanum wheels, and more particularly to a Mecanum wheel assembly fixture. Background Technology

[0002] A Mecanum wheel is an omnidirectional wheel that can move in all directions. It consists of a hub and multiple sets of rollers, also known as spinning wheels, that surround the hub in the circumferential direction.

[0003] The Mecanum spinning wheel has a predetermined angle between its axis and the hub axis, typically 45°. The hub consists of two sets of housings located at both ends of the spinning wheel, with corresponding holes on each housing that rotatably engage with the shafts at both ends of the spinning wheel. As the application of Mecanum spinning wheels becomes more widespread, the number of spinning wheels used in designs is also increasing. However, currently, factory assembly of Mecanum spinning wheels still relies on manual assembly. The process involves first fixing the shafts at one end of the spinning wheel to the corresponding holes on one side of the housing, then fastening the housing on the other side to the shaft at the other end of the spinning wheel, and finally connecting the two housings with fasteners. Because it is difficult to accurately align the shaft at the second end of the spinning wheel with the shaft holes on the second side of the housing, assembly of Mecanum spinning wheels is difficult and inefficient. Summary of the Invention

[0004] This application provides a Mecanum wheel assembly fixture that ensures precise alignment of the shaft holes on the first and second side shells of the Mecanum wheel with the spinning wheel, enabling rapid docking and fixing of the side shells and the spinning wheel, thereby improving the assembly efficiency of the Mecanum wheel.

[0005] To achieve the above technical effects, this application provides a Mecanum wheel assembly fixture, suitable for assembling and positioning Mecanum wheels. The Mecanum wheel includes a first side shell, a second side shell, and a plurality of spinning wheels rotatably connected between the first and second side shells. The Mecanum wheel assembly fixture includes a fixture body, which has an installation and positioning cavity. The bottom of the installation and positioning cavity has a first positioning mechanism for fixing the first side shell. A plurality of second positioning mechanisms are alternately arranged on the inner circumference of the installation and positioning cavity. The second positioning mechanisms are inclined at a preset angle relative to the axial direction of the installation and positioning cavity, and clamping grooves for clamping and positioning spinning wheels are formed between adjacent second positioning mechanisms.

[0006] In some embodiments, the first positioning mechanism includes a positioning groove arranged circumferentially along the bottom of the mounting positioning cavity, and the positioning groove and the shaft hole protrusion of the first side shell are correspondingly arranged.

[0007] In some embodiments, the first positioning mechanism further includes a locking pin, which is used to insert into a locking groove on the side of the first side shell opposite to the spinning wheel to lock the first side shell.

[0008] In some embodiments, the locking posts are arranged in pairs.

[0009] In some embodiments, the fixture body has a mounting slot through the center of the bottom of the mounting and positioning cavity, and the locking post is located on the outer periphery of the mounting slot.

[0010] In some embodiments, the second positioning mechanism includes a positioning spring and an adjustment protrusion protruding from the surface of the positioning spring;

[0011] The axial direction of the positioning spring and the mounting positioning cavity is at a first angle, which is equal to the angle between the axial direction of the wheat sheave and the axial direction of the spinning sheave.

[0012] The adjusting protrusion abuts against the surface of the spinning wheel inserted into the clamping groove, and is used to adjust the included angle between the axial direction of the spinning wheel and the axial direction of the mounting and positioning cavity to a second angle, the second angle being smaller than the first angle.

[0013] In some embodiments, the first angle is 45°.

[0014] In some embodiments, the second angle is 37°-42°.

[0015] In some embodiments, the adjusting protrusion and the inner wall of the mounting positioning cavity are connected by an adjusting spring.

[0016] In some embodiments, the positioning spring includes a first spring and a second spring, the first spring and the second spring being disposed on the upper and lower sides of the adjusting spring and coplanar with the adjusting spring.

[0017] Compared with the prior art, the technical solution provided in this application has the following advantages: When assembling the spinning wheel, the first side shell of the spinning wheel can be installed into the mounting and positioning cavity of the fixture body firstly, and the first side shell can be positioned by means of the first positioning mechanism. Then, the spinning wheel shaft at the first end of the spinning wheel is inserted into the circumferential shaft hole of the first side shell. The spinning wheel is limited and fixed by the clamping groove formed by the second positioning mechanism. The tilt angle of the spinning wheel is adjusted, and the spinning wheel is fixed by means of the shaft hole of the first side shell, the second positioning mechanism and the clamping groove, so that the spinning wheel shaft at the second end of all the spinning wheels is in a state of engagement with the shaft hole of the second side shell, so that the second side shell can be directly inserted and engaged with the spinning wheel shaft at the second end of all the spinning wheels by means of its shaft hole. After the second side shell and the spinning wheel shaft are assembled, the mounting and positioning cavity plays a positioning role for the first side shell, the spinning wheel and the second side shell, which facilitates the connection and fixation of the first side shell and the second side shell by fasteners.

[0018] The aforementioned Mecanum wheel assembly fixture can position the first side shell and the spinning wheel, making it easier for the second side shell to be directly fastened to the second end of the spinning wheel and connected and fixed to the first side shell, thus significantly improving the assembly efficiency of the Mecanum wheel.

[0033] To address the technical problem of low assembly efficiency of Mecanum wheels in existing technologies, this application provides a Mecanum wheel assembly fixture capable of positioning the first side shell 01 and all spinning wheels 02, facilitating the direct engagement of the second side shell 03 with the spinning wheels 02 and the first side shell 01, thereby improving the assembly efficiency of the Mecanum wheel. In this document, the Mecanum wheel is simply referred to as the "Mecanum wheel," meaning that the Mecanum wheel and the Mecanum wheel refer to the same object.

[0034] See Figure 1 and Figure 2This application provides a Mecanum wheel assembly fixture, applicable to the assembly process of Mecanum wheels. The Mecanum wheel assembly fixture includes a fixture body 10, which has an installation and positioning cavity. A first positioning mechanism is provided within the cavity, and a second positioning mechanism is provided circumferentially on the inner wall of the cavity. A clamping groove is formed between adjacent second positioning mechanisms, capable of clamping and positioning the spinning wheel 02. The installation and positioning cavity uses the first positioning mechanism at its bottom to position and fix the first side shell 01, facilitating the insertion of the spinning wheel 02 through its first end spindle shaft into the spindle shaft hole 04 of the first side shell 01, and fixing the spinning wheel 02 and the first side shell 01 within the installation and positioning cavity of the fixture body 10.

[0035] The mounting positioning cavity can also clamp and position the spinning wheel 02 using the second positioning mechanism on its inner circumference and the clamping groove between the second positioning mechanisms, and adjust and control the tilt angle of the spinning wheel 02 so that the spinning wheel shaft at the second end of the spinning wheel 02 can be kept in a state of docking with the spinning wheel shaft hole 04 of the second side shell 03, so that the second side shell 03 can be fastened to the spinning wheel shaft at the second end of the spinning wheel 02 with the spinning wheel shaft hole 04, realizing the docking of the first side shell 01 and the second side shell 03, the rotational connection between the spinning wheel 02 and the first side shell 01 and the second side shell 03, and thus completing the assembly of the Mecanum wheel.

[0036] The Mecanum wheel includes a first side shell 01, a second side shell 03, and several spinning wheels 02. The first side shell 01 and the second side shell 03 have largely the same structure. Spinning wheel shaft holes 04 are evenly and oppositely arranged circumferentially between their outer peripheries. The spinning wheel shaft holes 04 on the outer periphery of the first side shell 01 are used for rotatable connection with the spinning wheel shaft at the first end of the spinning wheel 02, and the spinning wheel shaft holes 04 on the outer periphery of the second side shell 03 are used for rotatable connection with the spinning wheel shaft at the second end of the spinning wheel 02. The first side shell 01 and the second side shell 03 are connected and fixed by fasteners and a mating structure between their inner peripheries. A shaft hole protrusion 05 is formed on the opposite side of the first side shell 01 and the second side shell 03 corresponding to the position of the spinning wheel shaft hole 04. The shaft hole protrusion 05 serves to seal and protect the spinning wheel shaft hole 04 and to limit the movement of the spinning wheel shaft.

[0037] The mating structure between the inner circumferences of the first side shell 01 and the second side shell 03 includes a mating post located on the inner circumference of one and a mating hole located on the inner circumference of the other. Fasteners connect the two along the axial direction of the mating post and the mating hole, thereby fixing the first side shell 01 and the second side shell 03 into a single unit. A plurality of spinning wheels 02 are rotatably connected to the spinning wheel shaft hole 04 between the outer circumferences of the first side shell 01 and the second side shell 03.

[0038] Because the total length of the spinning wheel 02 and the spinning wheel shafts protruding from its two ends is greater than the distance between the shaft holes of the first side shell 01 and the second side shell 03 after the Mecanum wheel is assembled, when the spinning wheel 02 is inserted into the spinning wheel shaft hole 04 of the first side shell 01 through the spinning wheel shaft at the first end, the spinning wheel shaft at the second end of the spinning wheel 02 will interfere with the spinning wheel shaft hole 04 of the second side shell 03. It is impossible to simultaneously ensure the docking of the docking post and the docking hole, as well as the docking of the spinning wheel shaft hole 04 and the spinning wheel shaft at the second end of the spinning wheel 02. Moreover, since the spinning wheel 02 achieves a rotational connection relative to the spinning wheel shaft by inserting the spinning wheel shaft into the spinning wheel shaft hole 04, there is a certain radial clearance between the spinning wheel 02 and the spinning wheel shaft. After the spinning wheel 02 is inserted into the spinning wheel shaft hole 04 of the first side shell 01 through the spinning wheel shaft at the first end, the consistency of the inclination of the spinning wheel and the spinning wheel shaft cannot be guaranteed, which makes it impossible for the spinning wheel shaft at the second end of the spinning wheel 02 to accurately dock with the spinning wheel shaft hole 04 of the second side shell 03.

[0039] The Mecanum wheel assembly fixture provided in this application positions and fixes the first side shell 01 through a first positioning mechanism at the bottom of the mounting positioning cavity, facilitating the insertion of the spinning wheel 02 through its first end spinning wheel shaft into the spinning wheel shaft hole 04 on the first side shell 01. Simultaneously, during the insertion of the spinning wheel 02 into the first side shell 01, the second positioning mechanism and the clamping groove formed by adjacent second positioning mechanisms clamp and position the spinning wheel 02, ensuring the consistency of the spinning wheel 02's inclination. At the same time, the inclination angle of the spinning wheel 02 is adjusted and controlled, ensuring that the spinning wheel shaft at the second end of the spinning wheel 02 is kept in a state where it can align with the spinning wheel shaft hole 04 of the second side shell 03. After the second side shell 03 is fastened to the second end of the spinning wheel 02 and docked with the first side shell 01, the mounting and positioning cavity of the fixture body 10 plays a positioning role for the first side shell 01, the spinning wheel 02 and the second side shell 03, so that the first side shell 01 and the second side shell 03 can be connected and fixed by fasteners in conjunction with the docking structure of the first side shell 01 and the second side shell 03, thereby realizing the assembly and forming of the Mecanum wheel.

[0040] In some embodiments, the setting of the first positioning mechanism is referenced Figure 1 and Figure 2 The first positioning mechanism includes several positioning grooves 11, which are evenly arranged circumferentially along the cavity of the mounting positioning chamber. The number and position of the positioning grooves 11 correspond to the spinning wheel shaft hole 04 of the first side shell 01. A shaft hole protrusion 05 is formed on the side of the first side shell 01 opposite to the spinning wheel 02. The shaft hole protrusion 05 corresponds to the spinning wheel shaft hole 04 of the first side shell 01. The shaft hole protrusion 05 is a closed protruding cover structure used to limit and protect the spinning wheel shaft at the first end of the spinning wheel 02. The corresponding arrangement of the positioning grooves 11 and the spinning wheel shaft hole 04, i.e., the shaft hole protrusion 05, achieves the initial positioning of the first side shell 01 when it is inserted into the bottom of the mounting positioning chamber.

[0041] Furthermore, to prevent relative rotation of the first side shell 01 and the mounting positioning cavity in the circumferential direction, and to prevent the shaft hole protrusion 05 from dislodging from the positioning groove 11, thereby ensuring the reliability of the spinning wheel 02's circumferential fixation in the mounting positioning cavity, the first positioning mechanism also includes a locking pin 12. The locking pin 12 protrudes upward from the bottom of the mounting positioning cavity along its axial direction. A locking groove 06 is provided on the side of the first side shell 01 facing away from the spinning wheel 02. When the locking pin 12 is inserted into the locking groove 06, the first side shell 01 is fixed circumferentially and radially relative to the mounting positioning cavity.

[0042] To improve the reliability of the fixation between the mounting positioning cavity and the first side shell 01, a pair of locking pins 12 are provided, each engaging with a pair of locking slots 06 on the first side shell 01. It is understood that, in specific implementations, multiple locking pins 12 can be provided as needed, simply by providing locking slots 06 matching the number and position of the locking pins 12 on at least one set of side shells of the Mecanum wheel to be assembled.

[0043] Meanwhile, in order to align the locking groove 06 of the first side shell 01 with the locking pin 12 of the fixture body 10 and to engage the shaft hole protrusion 05 of the first side shell 01 with the positioning groove 11 at the bottom of the mounting positioning cavity, the fixture body 10 has a mounting slot 13 in the central area of ​​the bottom of the mounting positioning cavity near the mounting positioning cavity. This allows the relative position of the first side shell 01 and the first positioning mechanism to be observed through the mounting slot 13 when the first side shell 01 is placed in the mounting positioning cavity, so that the two can be kept in alignment and the first side shell 01 can be quickly fixed in the mounting positioning cavity of the fixture body 10.

[0044] In some embodiments, the second positioning mechanism employs a cooperative structure of positioning springs 16 and adjusting protrusions 15. Multiple sets of positioning springs 16 are provided, and each positioning spring 16 is obliquely connected to the inner wall of the mounting positioning cavity. Each positioning spring 16 forms a first angle with the axial direction of the mounting positioning cavity. The multiple sets of positioning springs 16 are evenly and alternately arranged along the inner circumference of the mounting positioning cavity. Clamping grooves are formed between adjacent positioning springs 16 and are used to clamp and position the spinning wheel 02. The adjusting protrusions 15 protrude relative to the surface of the positioning springs 16. When the spinning wheel 02 is placed in the clamping grooves, the adjusting protrusions 15 abut against the surface of the spinning wheel 02, changing the angle between the axial direction of the spinning wheel 02 and the axial direction of the mounting positioning cavity.

[0045] In this embodiment, the adjusting spring 14 has a certain elastic deformation capability. When the adjusting protrusion 15 abuts against the surface of the first side of the spinning wheel 02, it squeezes the spinning wheel 02 to shift away from the adjusting protrusion 15, thereby squeezing the positioning spring 16 on the second side of the spinning wheel 02 to undergo a certain deformation. The adjusting protrusion 15, together with the positioning springs 16 on both sides of the spinning wheel 02, adjusts the angle between the axial direction of the spinning wheel 02 and the axial direction of the mounting positioning cavity.

[0046] The assembled Mecanum wheel has a first angle between the axial direction of the spinning wheel 02 and the axial direction of the Mecanum wheel. In other words, the angle between the axial direction of the positioning spring 16 and the mounting positioning cavity is equal to the angle between the axial direction of the Mecanum wheel and the axial direction of the spinning wheel. The setting of the adjusting protrusion 15, in conjunction with the installation of the spinning wheel 02, changes the tilt angle of the positioning spring 16, thereby changing the angle between the axial direction of the spinning wheel 02, which is fixed to the first side shell 01 and the mounting cavity, and the mounting cavity. The adjusting protrusion 15 is used to adjust the angle between the axial direction of the spinning wheel 02 and the axial direction of the mounting positioning cavity to a second angle, which is smaller than the first angle.

[0047] For example, the first angle is 45°, that is, the included angle between the positioning spring 16 and the axial direction of the mounting positioning cavity is 45°, and the included angle between the axial direction of the assembled Mecanum wheel and the axial direction of the spinning wheel 02 is also 45°. Figures 3 to 5 As shown, after the first side shell 01 is fixed in the mounting positioning cavity by the first positioning mechanism, the spinning wheel 02 is inserted and fixed to the spinning wheel shaft hole 04 of the first side shell 01 along the adjacent positioning springs 16, that is, along the clamping groove. When the surface of the first side of the spinning wheel 02 contacts the adjusting protrusion 15, the included angle between the axial direction of the spinning wheel 02 and the axial direction of the mounting positioning cavity changes until the spinning wheel shaft at the first end of the spinning wheel 02 is inserted into the spinning wheel shaft hole 04 of the first side shell 01. The adjusting protrusion 15 abuts against the first side surface of the spinning wheel 02 near the second end of the spinning wheel 02, and the included angle between the axial direction of the spinning wheel 02 and the axial direction of the mounting positioning cavity is adjusted to the second angle.

[0048] The size of the second angle can be changed by altering the position of the adjusting protrusion 15 or adjusting the thickness of the protrusion 15 relative to the surface of the positioning spring 16. The second angle is typically between 37° and 42°, preferably set to 37°. That is, when the axial direction of the spinning wheel 02 installed in the mounting positioning cavity is at a 37° angle to the axial direction of the mounting positioning cavity, or when the axial direction of the spinning wheel 02 installed in the mounting positioning cavity is at a 53° angle to the radial direction of the mounting positioning cavity, the alignment of the spinning wheel shaft at the second end of the spinning wheel 02, which is fixed by the mounting positioning cavity and the first side shell 01, with the spinning wheel shaft hole 04 of the second side shell 03 is optimal. This facilitates the direct fastening of the second side shell 03 to the spinning wheel shaft at the second end of the spinning wheel 02 and its docking and fixing with the first side shell 01. Finally, the first side shell 01 and the second side shell 03 are connected and fixed using fasteners and docking structures, thus completing the assembly process of the Mecanum wheel.

[0049] In some embodiments, to facilitate the insertion of the spinning wheel 02 into the spinning wheel shaft hole 04 of the first side shell 01 fixed by the mounting positioning cavity through the clamping groove between the positioning springs 16, the adjusting protrusion 15 is connected to the inner wall of the mounting positioning cavity through the adjusting spring 14. The adjusting spring 14 has a certain elastic deformation capability, and the elastic deformation coefficient of the adjusting spring 14 is greater than that of the positioning spring 16. When the spinning wheel 02 is inserted into the spinning wheel shaft hole 04 of the first side shell 01, the adjusting protrusion 15 is pressed first. The deformation of the adjusting spring 14 causes the positioning protrusion to move to be flush with the surface of the positioning spring 16, without affecting the insertion of the spinning wheel 02 into the spinning wheel shaft hole 04 of the first side shell 01 along the clamping groove. After the spinning wheel 02 is inserted into place, the adjusting protrusion 15 is released. Under the action of the restoring force of the adjusting spring 14, the adjusting spring 14 drives the adjusting protrusion 15 to abut against the surface of the spinning wheel 02 again. At the same time, it squeezes the positioning spring 16 on the other side of the spinning wheel 02 to deform, and adjusts the axial angle between the spinning wheel 02 and the axial angle of the mounting positioning cavity to the second angle, so as to facilitate the insertion of the second side shell 03 into the spinning wheel 02 and the docking and fixing with the first side shell 01.

[0050] In some embodiments, the positioning spring 16 is configured to include a first spring 17 and a second spring 18, and the adjusting spring 14 is located between the first spring 17 and the second spring 18, and the adjusting spring 14, the first spring 17 and the second spring 18 are coplanar. By configuring the positioning spring 16 as a separate structure of the first spring 17 and the second spring 18, it is convenient to guide and position the spinning wheel 02, and it is also convenient for the adjusting spring 14 to drive the positioning spring 16 to deform when the adjusting protrusion 15 abuts against the spinning wheel, so as to adjust the included angle between the axial direction of the spinning wheel 02 and the axial direction of the mounting positioning cavity to the second angle.
