Description

Technical Field

[0001] This utility model relates to the field of feed production spindle processing technology, and in particular to a positioning tool for feed production spindle processing. Background Technology

[0002] Positioning fixtures for feed production spindle machining refer to auxiliary devices, or clamps, specifically designed and manufactured to accurately, quickly, and safely fix and position the core drive shaft, i.e., the spindle, in feed production equipment during the machining process.

[0003] Traditional clamps use V-shaped iron blocks or fixed support blocks to support the spindle during clamping. However, most V-shaped iron blocks or fixed support blocks on the market do not have ball bearings on top. When the spindle is flipped, there is sliding friction between the spindle surface and the corresponding V-shaped iron block or fixed support block, which can easily cause scratches on the outer surface of the spindle during rotation. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a positioning fixture for machining the main shaft of feed production.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A positioning fixture for machining a feed production spindle includes a base. A fixed seat is fixedly installed on one side of the top of the base, and a support assembly and a movable seat are slidably arranged on the other side of the base via a slide rail. A three-jaw chuck is rotatably installed on the adjacent surfaces of the movable seat and the fixed seat via a bearing assembly. The support assembly includes a support base with a V-shaped top support surface. Multiple mounting slots are equally spaced on both sides of the top of the support base, and each mounting slot contains multiple placement cavities. A detachable ball body is placed in each placement cavity. An auxiliary assembly is magnetically inserted into the mounting slot. The auxiliary assembly includes an auxiliary plate with clearance holes at the ball body location. The auxiliary assembly and the support base are connected and limited by a plug-in assembly. Limiting components are provided on one side wall of the support base and below the corresponding mounting groove, and the insertion rod assembly and the support base are limited by the corresponding limiting components.

[0006] In addition, a preferred structure is that a magnet is installed at one end of the auxiliary plate between two adjacent clearance holes, and a magnetic groove with opposite polarity to the magnet is provided in the support base at the location of the magnet.

[0007] Furthermore, in a preferred configuration, the insertion rod assembly includes a connecting plate, with T-shaped insertion rods symmetrically installed on both sides of the upper part of one end of the connecting plate, and I-shaped insertion rods symmetrically installed on both sides of the lower part of one end of the connecting plate. An insertion hole for the limiting component to pass through is provided inside the connecting plate at the location of the limiting component.

[0008] Furthermore, in a preferred configuration, the support base has a main slot one for inserting the T-shaped plug at the T-shaped plug position, and a main slot two for inserting the I-shaped plug at the I-shaped plug position.

[0009] Furthermore, in a preferred configuration, the magnet block has an auxiliary insertion hole one for the T-shaped insertion rod to pass through at the corresponding T-shaped insertion rod position, and the auxiliary plate has an auxiliary insertion hole two for the I-shaped insertion rod to pass through at the corresponding I-shaped insertion rod position.

[0010] Furthermore, in a preferred configuration, the limiting assembly includes a positioning seat, with guide rods symmetrically mounted on both sides of the outer wall of the positioning seat, and a movable component movably sleeved on the outer wall of the positioning seat.

A three-jaw chuck 3 is rotatably installed on the adjacent surfaces of the movable seat 22 and the fixed seat 21 via a bearing assembly. The three-jaw chuck on one side of the fixed seat 21 is driven by a servo motor.

[0017] The support component 5 includes a support base 51. The top support surface of the support base 51 is V-shaped. Multiple mounting slots are equally spaced on both sides of the top of the support base 51. Each mounting slot has multiple placement cavities. A detachable ball body 52 is placed in each placement cavity. An auxiliary component is magnetically inserted into the mounting slot. The auxiliary component includes an auxiliary plate 55. An clearance hole 551 is opened in the auxiliary plate 55 at the ball body 52. ​​The auxiliary component and the support base 51 are connected and limited by a plug-in component. Limiting components 53 are provided on one side wall of the support base 51 and below the corresponding mounting groove, and the insertion rod assembly and the support base 51 are limited by the corresponding limiting components 53.

[0018] A magnet block 552 is installed at one end of the auxiliary plate 55 between two adjacent clearance holes 551, and a magnetic groove with opposite polarity to the magnet block is opened in the support base 51 at the magnet block 552.

[0019] The plug assembly includes a connecting plate 54. T-shaped plugs 542 are symmetrically installed on both sides of the upper part of one end of the connecting plate 54, and I-shaped plugs 541 are symmetrically installed on both sides of the lower part of one end of the connecting plate 54. A plug hole for the limiting component 53 to pass through is opened in the connecting plate 54 at the limiting component 53.

[0020] The support base 51 has a main slot 1 for inserting the T-shaped plug 542 at the T-shaped plug 542, and the support base 51 has a main slot 2 for inserting the I-shaped plug 541 at the I-shaped plug 541.

[0021] The magnet block 552 has an auxiliary insertion hole 1 at the T-shaped insertion rod 542 for the T-shaped insertion rod 542 to pass through, and the auxiliary plate 55 has an auxiliary insertion hole 2 at the I-shaped insertion rod 541 for the I-shaped insertion rod 541 to pass through.

[0022] The limiting component 53 includes a positioning seat 531. Guide rods 534 are symmetrically installed on both sides of the outer wall of the positioning seat 531. A movable part 532 is movably sleeved on the outer wall of the positioning seat 531. A guide rod 535 is fixedly installed on one side of the outer wall of the movable part 532. The outer diameter of the guide rod 534 is the same as the outer diameter of the guide rod 535. The outer diameter of the positioning seat 531 is the same as the outer diameter of the movable part 532.

[0023] The movable part 532 and the positioning seat 531 are connected and limited by the positioning rod 533. The positioning rod 533 includes a handle rod and a magnet rod. The guide rod 1 534 has an auxiliary slot for the magnet rod to be inserted, and the auxiliary slot has a magnetic layer with the opposite polarity to the magnet rod. The guide rod 2 535 has a through hole for the magnet rod to pass through.

[0024] Furthermore, a lead screw drive mechanism is provided on one side of the top of the base 1. The movable seat is driven by the lead screw drive mechanism, and the lead screw drive unit drives the movable seat to perform horizontal linear motion. All exposed parts of the lead screw drive unit are equipped with telescopic dust covers (not shown in the figure).

[0025] It is worth noting that the two sets of three-jaw chucks must be coaxial when assembled. The specific structure and working principle of the three-jaw chuck and the lead screw drive mechanism are all existing technologies that are currently publicly available on the market, so they will not be elaborated on further.

[0026] In this embodiment, the feed production spindle to be processed is placed on top of the support base, and one end of it is clamped and fixed by the three-jaw chuck of the fixed base. The movable base is driven to move towards the spindle and press against it by the screw drive mechanism, and is clamped by the corresponding three-jaw chuck. When it is necessary to rotate the clamped spindle, only the servo motor needs to be started. The servo motor drives the three-jaw chuck to rotate, and at the same time, it drives the spindle to rotate. During the rotation of the spindle, the friction between the spindle and the support base is changed to rolling friction, which reduces scratches on the outer wall of the spindle and protects its outer surface.

[0027] Meanwhile, the ball body is detachable. When the ball body is worn, it can be disassembled and replaced. By rotating the moving part until its guide rod 2 535 and guide rod 1 534 are flush and its through hole is aligned with the auxiliary slot, and the positioning rod is inserted, the insertion rod assembly can be disassembled and the auxiliary assembly can be disassembled. At the same time, the worn ball body can be taken out and replaced.

[0028] The replaced ball bearing body is placed in the placement cavity, and the auxiliary plate is aligned with the mounting slot and inserted until it is fully inserted. The magnet block 552 is inserted into the magnetic slot and magnetically connected to the magnetic slot. Then, the T-shaped insert 542 in the insert assembly is aligned with the main slot one of the support base 51, and the I-shaped insert 541 is aligned with the main slot two of the support base 51 and inserted until it is fully inserted.

[0029] Then, remove the positioning rod 533 and rotate the movable part so that its guide rod two is not aligned with its guide rod one. Then, insert the positioning rod 533 into the guide rod one of the positioning seat, thereby completing the replacement of the ball body. In this invention, by using two sets of symmetrically arranged three-jaw chucks in conjunction with support components, a screw drive mechanism, and a servo motor, feed production spindles of different sizes within a certain range can be clamped. The clamped spindles can also be flipped. During the rotation of the spindle, the friction between the spindle and the support seat is changed to rolling friction, reducing scratches on the outer wall of the spindle and protecting its outer surface.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
