Description

Technical Field

[0001] This application relates to the field of positioning carriers, and more particularly to a positioning carrier suitable for gear shafts. Background Technology

[0002] Gear shafts are core components in mechanical transmission systems, serving the dual functions of gears and shafts to transmit torque and motion. They typically consist of a single-piece molded gear section and shaft body. Gear shafts are mostly made of high-strength alloy steel and require precision heat treatment and finishing processes such as carburizing, quenching, and gear grinding to ensure surface hardness, wear resistance, and core toughness. They are widely used in the assembly of critical equipment such as gearboxes and reduction gears.

[0003] In order to transfer the gear shaft to the corresponding assembly station, the gear shaft needs to be securely positioned in the required position by a positioning carrier so that it can be accurately gripped.

[0004] In existing related technologies, the positioning carrier includes a base and a gear shaft guide sleeve. The gear shaft guide sleeve is fixedly installed on the base, and the gear shaft guide sleeve has a gear shaft positioning cavity in the vertical direction for accommodating the gear shaft. The specifications of the gear shaft positioning cavity of the gear shaft guide sleeve need to be adapted to the specifications of the gear shaft to reduce the clearance that would cause the gear shaft to wobble. During positioning, the gear shaft needs to be vertically inserted into the gear shaft positioning cavity, and the gear shaft is limited by the inner wall of the gear shaft positioning cavity to prevent the gear shaft from deviating.

[0005] Regarding the aforementioned technologies, it is quite inconvenient to change to different positioning carriers when positioning and conveying gear shafts of different specifications. Summary of the Invention

[0006] To facilitate the replacement of the positioning carrier according to the specifications of the gear shaft, this application provides a positioning carrier suitable for gear shafts.

[0007] The positioning carrier for gear shafts provided in this application adopts the following technical solution: A positioning carrier for a gear shaft includes a positioning base and a gear shaft guide sleeve. The positioning base has a guide sleeve slot, and the gear shaft guide sleeve is detachably inserted into the guide sleeve slot. The gear shaft guide sleeve has a gear shaft positioning cavity, the specifications of which are adapted to the specifications of the gear shaft. The gear shaft guide sleeve is provided with a guide sleeve annular groove and a guide sleeve vertical groove. The guide sleeve annular groove is arranged in a circular shape and is horizontally positioned. The gear shaft guide sleeve is equipped with a quick-release pin, which is inserted or threaded into the gear shaft guide sleeve. The quick-release pin has a pin limiting end, which is inserted into the guide sleeve annular groove. The positioning base is equipped with a limiting block, which slides vertically to engage with the vertical groove of the guide sleeve.

[0008] By adopting the above technical solution, when it is necessary to replace the gear shaft guide sleeve with a corresponding specification, the quick-release pin can be disengaged from the guide sleeve annular groove, allowing the gear shaft guide sleeve to be pulled out of the guide sleeve slot. When replacing the guide sleeve slot, align the vertical groove of the guide sleeve with the limiting block and insert it into the guide sleeve slot. Then, insert the quick-release pin into the guide sleeve annular groove and press it against the groove to replace and install the gear shaft guide sleeve on the positioning base. This makes it easier to change the positioning carrier according to the specifications of the gear shaft.

[0009] Optionally, the opening of the gear shaft positioning cavity is chamfered.

[0010] By adopting the above technical solution, it is beneficial to reduce the degree of collision between the gear shaft positioning cavity and the gear shaft, thereby making it easier to insert the gear shaft into the gear shaft positioning cavity.

[0011] Optionally, the pin limiting end is spherically shaped.

[0012] By adopting the above technical solution, it is beneficial to reduce the degree of collision between the guide sleeve groove and the pin limiting end, thereby facilitating the insertion of the gear shaft into the gear shaft positioning cavity.

[0013] Optionally, the gear shaft guide sleeve includes a bottom guide sleeve and a top guide sleeve, the guide sleeve annular groove and the guide sleeve vertical groove are formed in the bottom guide sleeve, the top guide sleeve is located at the top of the bottom guide sleeve, and the top guide sleeve is detachably fitted to the bottom guide sleeve; The bottom guide sleeve has a toothed groove, the top guide sleeve has a rotating shaft groove, and the toothed shaft positioning cavity is formed by the toothed groove and the rotating shaft groove communicating with each other.

[0014] By adopting the above technical solution, it is convenient to replace the top guide sleeve of different specifications when the component is damaged or according to the gear shaft of different shaft specifications, or to replace the bottom guide sleeve of different specifications according to the gear shaft of different tooth specifications, thereby reducing the occurrence of overall replacement and thus reducing the manufacturing cost of periodic vehicles.

[0015] Optionally, the top guide sleeve is inserted into and fitted with the bottom guide sleeve.

[0016] By adopting the above technical solution, the fitting method between the top guide sleeve and the bottom guide sleeve is relatively simple and not easily damaged during use.

[0017] Optionally, the positioning base has two vehicle positioning holes through it, and the two vehicle positioning holes are located on both sides of the positioning base.

[0018] By adopting the above technical solution, when using the positioning vehicle, inserting two positioning pins into the two positioning holes of the vehicle respectively can lock the positioning vehicle, making the positioning vehicle less prone to tilting.

[0019] Optionally, the limiting block is installed on the positioning base by bolts.

[0020] By adopting the above technical solution, the limit block is easier to replace.

[0021] Optionally, the positioning base is equipped with a gear shaft magnet, which is located at the bottom of the gear shaft positioning cavity.

[0022] By adopting the above technical solution, for ferromagnetic gear shafts, the gear shaft magnet is used to attract the gear shaft, making it less likely for the gear shaft to wobble in the gear shaft positioning cavity.

[0023] In summary, this application includes at least one of the following beneficial technical effects: 1. When it is necessary to replace the gear shaft guide sleeve with a corresponding specification, simply remove the pin limiting end of the quick-release pin from the guide sleeve annular groove to pull the gear shaft guide sleeve out of the guide sleeve slot. When replacing the guide sleeve slot, align the vertical groove of the guide sleeve with the limiting block and insert it into the guide sleeve slot. Then, insert the quick-release pin into the guide sleeve annular groove and press it against the guide sleeve annular groove to replace and install the gear shaft guide sleeve on the positioning base. This makes it easier to change the positioning carrier according to the specifications of the gear shaft. 2. When using the positioning vehicle, insert the two positioning pins into the two positioning holes of the vehicle respectively to lock the positioning vehicle, making the positioning vehicle less prone to tilting. 3. For ferromagnetic gear shafts, using a gear shaft magnet to attract the gear shaft will make it less likely for the gear shaft to wobble within the gear shaft positioning cavity.

[0030] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0031] Example 1: This application discloses a positioning carrier suitable for gear shafts. (Refer to...) Figure 1 The positioning carrier for gear shafts includes a positioning base 1 and a gear shaft guide sleeve 2.

[0032] Reference Figure 1 and Figure 2 The positioning base 1 is made of metal, preferably steel. Two cylindrical positioning feet 11 are bolted to the bottom of the positioning base 1. These feet 11 are located on opposite sides of the positioning base 1, allowing the positioning base 1 to be inserted into suitable cylindrical positioning slots (not shown in the figure), preventing it from shifting. The positioning base 1 also has two carrier positioning holes 101 extending through it. These holes are located on opposite sides of the positioning base 1, and the two positioning holes 101 and the two positioning feet 11 are arranged in a cross shape, further preventing the positioning base 1 from shifting by inserting the two positioning feet (not shown in the figure) into the two carrier positioning holes 101 respectively.

[0033] Reference Figure 1 and Figure 2 The top of the positioning base 1 has a guide sleeve slot 102, which is used for the gear shaft guide sleeve 2 to be detachably inserted into the positioning base 1. Figure 3 The gear shaft guide sleeve 2 includes a bottom guide sleeve 21 and a top guide sleeve 22. The top guide sleeve 22 is located on top of the bottom guide sleeve 21, and the material of the top guide sleeve 22 can be nylon. The top guide sleeve 22 is inserted into the bottom guide sleeve 21 so that it can be replaced separately if the top guide sleeve 22 or the bottom guide sleeve 21 is damaged or non-compliant.

[0034] Reference Figure 4 The bottom guide sleeve 21 has a toothed groove 211, and the top guide sleeve 22 has a rotating shaft groove 221. The toothed groove 211 and the rotating shaft groove 221 communicate to form a gear shaft positioning cavity. The gear shaft positioning cavity is adapted to a gear shaft of the corresponding specification, and the toothed groove 211 is adapted to the toothed part of the gear shaft, while the rotating shaft groove 221 is adapted to the rotating part of the gear shaft. The opening of the gear shaft positioning cavity is chamfered to reduce the degree of collision between the gear shaft positioning cavity and the gear shaft, thereby facilitating the insertion of the gear shaft into the gear shaft positioning cavity.

[0035] The bottom guide sleeve 21 has a guide sleeve annular groove 212 and a guide sleeve vertical groove 213 on its outer side. The guide sleeve annular groove 212 is circular and horizontal, while the guide sleeve vertical groove 213 is connected to the guide sleeve annular groove 212 and is vertical. When the gear shaft guide sleeve 2 is inserted into the guide sleeve slot 102, the entire guide sleeve annular groove 212 and a portion of the guide sleeve vertical groove 213 are located inside the guide sleeve slot 102. The gear shaft guide sleeve 2 is detachably fitted with a quick-release pin 3 through a pin hole on its outer side that is connected to the guide sleeve slot 102. The quick-release pin 3 has a pin limiting end 31, which is spherical and is inserted into the guide sleeve annular groove 212 to prevent the gear shaft guide sleeve 2 from moving vertically. Furthermore, by pressing the quick-release pin 3 against the inner wall of the guide sleeve annular groove 212, the gear shaft guide sleeve 2 is also less prone to shaking. The material of the pin limiting end 31 can be selected as rubber, silicone or plastic, etc., to reduce wear and scratches.

[0036] The positioning base 1 is bolted to install the limiting block 4. The limiting block 4 slides vertically to engage with the vertical groove 213 of the guide sleeve, and the limiting block 4 is adapted to the vertical groove 213 of the guide sleeve, so that the gear shaft guide sleeve 2 is not prone to lateral swing. Thus, the gear shaft guide sleeve 2 is quickly and securely installed on the positioning base 1 by the limiting block 4 and the quick-release pin 3.

[0037] The implementation principle of a positioning carrier applicable to gear shafts in this application embodiment is as follows: When it is necessary to replace the gear shaft guide sleeve 2 of the corresponding specification, the pin limiting end 31 of the quick-release pin 3 is disengaged from the guide sleeve annular groove 212, and the gear shaft guide sleeve 2 can be pulled out from the guide sleeve slot 102. When replacing the guide sleeve slot 102, the vertical groove 213 of the guide sleeve is aligned with the limiting block 4 and inserted into the guide sleeve slot 102. Then, the quick-release pin 3 is inserted into the guide sleeve annular groove 212 and abuts against the guide sleeve annular groove 212, so that the gear shaft guide sleeve 2 can be replaced and installed on the positioning base 1, thereby making it easier to replace the positioning carrier according to the specifications of the gear shaft.

[0038] Example 2: This application discloses a positioning carrier suitable for gear shafts, referring to... Figure 5 The difference from Example 1 is as follows: Difference 1: Quick-release pin 3 is threaded into gear shaft guide sleeve 2; Difference 2: The positioning base 1 is fixedly installed with a gear shaft magnet 13. The gear shaft magnet 13 is located at the bottom of the gear shaft positioning cavity. By attracting the ferromagnetic gear shaft through the gear shaft magnet 13, the gear shaft will be less likely to shake in the gear shaft positioning cavity.

[0039] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
