Description

Technical Field

[0001] This utility model relates to the field of double-ear parts clamping technology, specifically a double-ear parts clamping fixture suitable for CNC lathes. Background Technology

[0002] Double-ear parts are a common type of mechanical component, widely used due to their unique double-ear design. These parts are typically roughly arc-shaped, and their diverse shapes and sizes place high demands on fixture design. While existing CNC lathe double-ear part fixtures on the market can meet basic clamping requirements to some extent, they still have many shortcomings.

[0003] Specifically, existing double-ear part fixtures often lack sufficient flexibility and adaptability, making it difficult to effectively handle double-ear parts of different sizes and specifications. Due to the significant dimensional differences in double-ear parts, traditional fixtures often require changing clamping components of different specifications or adjusting the clamping position to adapt to different parts. This not only increases the complexity of operation but also reduces production efficiency. Utility Model Content

[0004] (I) Purpose of the utility model

[0005] In view of this, the purpose of this utility model is to provide a double-eared parts fixture suitable for CNC lathes, which solves the problems mentioned in the background above.

[0006] (II) Technical Solution

[0007] A double-eared parts clamping fixture suitable for CNC lathes includes a base. A mounting seat and a cylinder are fixedly mounted on the top of the base. One end of the cylinder is connected to a movable rod, which passes through one end of the mounting seat. One end of the movable rod is connected to a housing. Another set of housings is fixedly mounted on one side of the top of the mounting seat. A movable mechanism is provided inside the housing. The movable mechanism includes two sets of fixed blocks, each with a circular through groove on its outer surface. A bidirectional lead screw is movably mounted in the circular through groove, and two sets of sliding seats are movably mounted on the outer surface of the bidirectional lead screw. One end of each sliding seat is connected to a connecting block, and one end of the connecting block is connected to a clamping block. One end of the bidirectional lead screw is connected to a motor.

[0008] Preferably, a limiting groove is formed on the top outer surface of the mounting base, and a limiting block is movably installed on the inner wall of the limiting groove, with one end of the limiting block being fixedly connected to the bottom end of the outer shell.

[0009] Preferably, the motor is fixedly connected to the fixing block.

[0010] Preferably, a top plate is movably mounted on the top of the outer casing.

[0011] Preferably, one side of the outer surface of the clamping block is serrated.

[0012] Preferably, the outer surface of the clamping block is covered with rubber.

[0013] Preferably, an outer plate is fixedly installed on one side of the outer shell, and a groove is provided on the outer surface of the outer plate, in which a connecting block is movably engaged.

[0014] As can be seen from the above technical solutions, this application has the following beneficial effects:

[0015] 1. This utility model utilizes a motor-driven bidirectional lead screw to rotate, thereby moving the sliding seat and clamping block, achieving flexible clamping of double-ear parts of different sizes. The connection design between the limiting block and the sliding seat, as well as the V-shaped distribution of the limiting block in the limiting groove, further enhances the adaptability of the fixture, ensuring stable clamping of double-ear parts of both large and small sizes. This not only improves processing efficiency but also reduces time wasted on changing fixtures, bringing great convenience to production.

[0016] 2. This utility model features a serrated design on one side of the clamping block's outer surface, which more effectively grips the part's surface, providing a stable clamping force and ensuring that the double-eared part will not shift due to vibration or external force during processing. Simultaneously, the rubber layer covering the outer surface of the clamping block plays a crucial protective role, reducing damage to the surface of the double-eared part during clamping and effectively protecting the part's processing quality.

[0023] The following description is exemplary in nature and is not intended to limit the scope, application, or use of this disclosure. It should be understood that in all these figures, the same or similar reference numerals indicate the same or similar parts and features. The figures are merely schematic representations of the concept and principles of embodiments of this disclosure and do not necessarily show the specific dimensions and scale of the various embodiments of this disclosure. Certain details or structures of embodiments of this disclosure may be exaggerated in particular portions of certain figures.

[0024] Please see Figure 1-5 One embodiment provided by this utility model:

[0025] A double-eared parts clamping fixture suitable for CNC lathes includes a base 1. A mounting seat 2 and a cylinder 3 are fixedly installed on the top of the base 1. One end of the cylinder 3 is connected to a movable rod 4, which passes through one end of the mounting seat 2. One end of the movable rod 4 is connected to a housing 6. Another set of housings 6 is fixedly installed on one side of the top of the mounting seat 2. A movable mechanism is provided inside the housing 6. The movable mechanism includes two sets of fixing blocks 916. The outer surface of both sets of fixing blocks 916 is provided with a circular through groove. A bidirectional lead screw 912 is movably installed in the circular through groove. Two sets of sliding seats 913 are movably installed on the outer surface of the bidirectional lead screw 912. One end of the two sets of sliding seats 913 is connected to a connecting block 914. One end of the connecting block 914 is connected to a clamping block 8. One end of the bidirectional lead screw 912 is connected to a motor 915.

[0026] Furthermore, a limiting groove 5 is formed on the top outer surface of the mounting base 2, and a limiting block 9 is movably installed on the inner wall of the limiting groove 5. One end of the limiting block 9 is fixedly connected to the bottom end of the housing 6. The movable installation of the limiting block 9 in the limiting groove 5 not only restricts the movement direction of the housing 6, but also allows it to move freely within a certain range to accommodate parts of different sizes. This enhances the flexibility and adaptability of the fixture.

[0027] Furthermore, the motor 915 is fixedly connected to the fixed block 916. This fixed connection reduces transmission errors caused by vibration or loosening, ensures the precise rotation of the bidirectional lead screw 912, and thus improves the positioning accuracy of the clamping block.

[0028] Furthermore, a top plate 911 is movably mounted on the top of the outer casing 6. The top plate 911 is movably connected by bolts, which facilitates disassembly and allows for inspection of the interior of the outer casing 6.

[0029] Furthermore, one side of the outer surface of the clamping block 8 is serrated. The serrated design increases the friction between the clamping block 8 and the double-ear parts, thereby improving the stability of the clamping.

[0030] Furthermore, the outer surface of the clamping block 8 is covered with rubber, which reduces damage to the surface of the double-eared parts caused by the clamping block 8. During the clamping process, the rubber layer can buffer the clamping force and prevent the surface of the parts from being scratched or deformed.

[0031] Furthermore, an outer plate 7 is fixedly installed on one side of the outer casing 6, and a groove is formed on the outer surface of the outer plate 7. A connecting block 914 is movably engaged in the groove, and the groove provides a stable moving track for the connecting block 914. This design ensures the smoothness and accuracy of the clamping block 8 during movement.

[0032] Working principle: First, the double-ear part is placed on the top outer surface of the mounting base 2. The mounting base 2 provides a stable working platform, ensuring the stability of the double-ear part during the machining process.

[0033] Next, the motors 915 driving the movable mechanisms in the two sets of housings 6 cause the bidirectional lead screw 912 to begin rotating. The motors 915, acting as the power source, transmit their rotational motion to the bidirectional lead screw 912 via the fixed block 916. The special structure of the bidirectional lead screw 912 allows it to simultaneously drive the two sets of sliding seats 913 to move in opposite or opposite directions within the circular slot during rotation.

[0034] As the sliding base 913 moves, it connects to the clamping block 8 via the connecting block 914, thus the clamping block 8 also moves. This movement allows the two sets of clamping blocks 8 to gradually move closer to or further away from the double-eared parts, thereby accommodating double-eared parts of different sizes. In particular, since the limiting block 9 is connected to the sliding base 913, and the two sets of limiting blocks 9 are distributed in a V-shape in the limiting groove 5 of the mounting base 2, this design further enhances the fixture's adaptability to double-eared parts of different sizes.

[0035] As the clamping block 8 gradually approaches the double-ear parts, the serrated design on one side of the outer surface of the clamping block 8 can more effectively grip the surface of the parts and provide a stable clamping force. At the same time, the rubber layer covering the outer surface of the clamping block 8 can reduce damage to the surface of the double-ear parts during clamping and protect the machining quality of the parts.

[0036] After the clamping block 8 successfully clamps the double-eared parts, the driving cylinder 3 causes the movable rod 4 to move the outer shell 6. The outer shell 6 moves closer to another set of outer shells 6, thereby further securing the clamped double-eared parts and ensuring that they will not loosen due to vibration or external force during processing.

[0037] 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.
