Description

Technical Field

[0001] The invention relates to the technical field of tooling fixtures, and in particular to a special fixture for roller body ear milling and a use method thereof. Background Art

[0002] The roller body is a mechanical component widely used in industrial applications. It is mainly used to support and guide the movement of moving parts, reduce friction and improve movement efficiency. Common roller body structures are as follows: Figure 1 As shown, a roller groove for mounting the roller body is provided at the bottom, and the two side walls of the roller groove are ear-flat structures, and the two ear-flat outer wall surfaces need to be milled. However, in the traditional roller body ear-flat milling process, a single fixture is usually used to clamp and process a single workpiece. Since only one workpiece can be processed at a time, and frequent clamping and unloading operations are required, the processing efficiency is low, which is not suitable for large-scale production needs, and the labor intensity is increased, resulting in a high processing cost for a single workpiece, which is not conducive to the economic benefits of the enterprise. Summary of the invention

[0003] One of the purposes of the present invention is to provide a special fixture for milling ear flats of roller bodies, so as to quickly clamp multiple workpieces, improve processing efficiency and reduce labor intensity.

[0004] In order to solve the above technical problems, the present invention adopts the following technical solution: a special fixture for milling ears of roller bodies, comprising a base, characterized in that two positioning rods are arranged in parallel on the base, a gap for placing multiple workpieces is formed between the two positioning rods, a limiting rod parallel to the positioning rod is arranged above the gap, and the limiting rod is used to pass through the roller grooves of all workpieces and press the workpieces onto the base.

[0005] Preferably, a support is respectively provided at the left and right ends of the base, and the two ends of the positioning rod are connected to the left and right supports.

[0006] More preferably, a protrusion is provided on the upper portion of the support, the protrusion is provided with a through hole, and the two ends of the limiting rod are respectively passed through the through holes of the left and right protrusions.

[0007] More preferably, a support sleeve is fixedly mounted on the inner wall surface of the through hole.

[0008] More preferably, one end of the limiting rod is provided with a head with an outer diameter larger than the inner diameter of the through hole.

[0009] More preferably, a pad for placing a workpiece is fixedly mounted on the base between the two supports.

[0010] In addition, the present invention also provides a method for roller body ear flattening using the above-mentioned roller body ear flattening special fixture, which comprises the following steps: a. Arrange multiple workpieces in sequence and place them in the gap between the two positioning rods; b. After passing the limit rod through one of the raised through holes, pass it through the roller grooves of all the workpieces in sequence, and then pass it into another raised through hole to complete the clamping; c. Mill all clamped workpieces.

[0011] Preferably, the method is performed using a CNC milling machine.

[0012] Compared with the prior art, the present invention allows multiple roller body workpieces to be arranged in sequence and placed between the two positioning rods by arranging two positioning rods in parallel on the base, thereby achieving simultaneous clamping of multiple workpieces. This design significantly reduces the time and labor required for clamping a single workpiece, thereby improving the efficiency of batch processing, and the operator only needs to put the workpiece into the gap between the positioning rods and then fix it with the limit rod to complete the clamping. This simplified operation process reduces the requirements for operator skills, reduces the difficulty of operation and labor intensity. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with embodiments and drawings. The contents mentioned in the implementation modes are not intended to limit the present invention.

[0016] It should be noted in advance that, in the present invention, unless otherwise clearly specified and limited, the terms such as "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. In addition, in the present invention, unless otherwise clearly specified and limited, the first feature "on" or "under" the second feature may include the first and second features being in direct contact, and may also include the first and second features not being in direct contact but being in contact through another feature between them.

[0017] like Figures 1 to 4 As shown, a special fixture for milling ears of roller bodies includes a base 1, two positioning rods 2 are arranged in parallel on the base 1, a gap for placing multiple workpieces 3 is formed between the two positioning rods 2, and a limiting rod 4 parallel to the positioning rods 2 is arranged above the gap. The limiting rod 4 is used to pass through the roller grooves of all workpieces 3 and press the workpieces 3 onto the base 1.

[0018] In the above structure, a support 5 is provided at the left and right ends of the base 1, and the two ends of the positioning rod 2 are connected to the left and right supports 5. By providing the supports 5 at both ends of the base 1 and connecting the positioning rod 2 to these supports 5, a stable structural frame is formed. This design enhances the stability and rigidity of the entire fixture, ensures that the positioning of the workpiece 3 is more accurate and firm during the processing, and reduces the processing error caused by deformation or instability of the fixture.

[0019] Among them, the upper part of the support 5 is provided with a protrusion 5a, and the protrusion 5a is provided with a through hole, and the two ends of the limit rod 4 are respectively penetrated through the through holes of the left and right protrusions 5a. The inner wall surface of the through hole is also fixedly mounted with a support sleeve 6. The design of the protrusion 5a and the through hole allows the limit rod 4 to flexibly pass through and be fixed on the support 5, and the use of the support sleeve 6 provides additional support and protection to prevent the through hole from being worn or enlarged due to long-term friction. This design improves the durability and maintainability of the clamp, and also ensures the flexibility and accuracy of the limit rod in operation.

[0020] In addition, one end of the limiting rod 4 is provided with a head with an outer diameter larger than the inner diameter of the through hole, so as to play a limiting role, so that the head can abut against the protrusion 5a, thereby ensuring the precise positioning of the workpiece 3 during the processing.

[0021] In this embodiment, a pad 7 for placing the workpiece 3 is fixedly mounted on the base 1 between the two supports 5, which can provide a stable and flat workpiece support platform to ensure the stability of the workpiece during processing. This design helps to reduce processing errors caused by the instability of the workpiece, and also protects the surface of the workpiece to avoid damage during the clamping process. The pad 7 can be detachably mounted on the base 1, so that the presence of the pad 7 also helps to quickly replace and adjust the workpiece, thereby improving processing efficiency.

[0022] The steps for performing roller ear flattening using the special fixture for roller ear flattening provided in the above-mentioned embodiment are roughly as follows: first, place the workpiece 3 to be processed on the pad 7 on the base 1, ensure that the workpiece is located between the two positioning rods 2, and insert one end of the limit rod 4 into the through hole of a protrusion 5a, and then pass through the roller grooves of all the workpieces 3 in sequence, and then pass through the through hole of another protrusion 5a, until the head of the limit rod 4 is against the protrusion 5a to complete the clamping. Start the milling machine or other processing equipment to mill the two ear-flat side wall structures of the roller groove of the clamped workpiece 3. Since the workpiece has been precisely fixed, the processing of batches of workpieces can be completed efficiently and accurately. After the milling process is completed, turn off the processing equipment, then remove the limit rod 4 from the through hole of the protrusion 5a, release the workpiece, and the milling process of a batch of workpieces is completed.

[0023] The special fixture for milling ears of roller bodies of the present invention forms a gap for placing the workpiece 3 by arranging two positioning rods 2 in parallel on the base 1, and uses the upper limiting rod 4 to pass through the roller groove of the workpiece 3 to fix the workpiece 3 on the base, thereby realizing fast and accurate clamping of multiple roller body workpieces, thereby improving batch processing efficiency, ensuring processing accuracy, reducing labor intensity and production costs, and at the same time simplifying the operating process and enhancing the stability and durability of the fixture.

[0024] In order to make it easier for ordinary technicians in the field to understand the improvements of the present invention over the prior art, some drawings and descriptions of the present invention have been simplified, and the above-mentioned embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the protection scope of the present invention.
