Description

Technical Field

[0001] This utility model relates to the field of polishing technology, and in particular to a grinding head structure for a non-circular rod groove polishing machine. Background Technology

[0002] In modern industrial production, the application of irregularly shaped rods is becoming increasingly widespread, and the machining accuracy and surface quality of their grooves have a crucial impact on the performance and service life of the products. In order to meet the requirements of high-precision machining, grinding has become an indispensable part of the production process of irregularly shaped rods, and the grinding head, as a key component that directly acts on the workpiece, directly determines the grinding effect through its structure and performance.

[0003] Traditional grinding heads have several drawbacks when grinding grooves on irregularly shaped rods. First, most traditional grinding heads are one-piece, fixed structures with fixed dimensions and shapes, making them difficult to adapt to grooves on irregularly shaped rods of varying sizes and shapes. When encountering rods with deep or wide grooves, they cannot effectively conform to the groove, resulting in uneven grinding and incomplete grinding of certain areas, severely impacting product quality. Second, the installation and removal of traditional grinding heads is cumbersome and complex, often requiring multiple specialized tools, consuming significant time and labor costs. This drawback is particularly pronounced when changing grinding heads to adapt to different processing requirements, greatly reducing production efficiency. Utility Model Content

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings.

[0018] Combination Figure 1 and Figure 2 As shown, the grinding head structure of the irregular rod groove polishing machine of this utility model includes a fixed block 7 and a support block 71. The support block 71 is fixed to the end of the fixed block 7. U-shaped groove polishing head 1 72 is provided on both sides of the support block 71. U-shaped groove polishing head 2 73 is provided at the bottom of the support block 71. Locking plates 74 are provided at the front and rear ends of the support block 71.

[0019] The locking plate 74 has an insertion hole 741 inside, the support block 71 has a threaded hole 744 at the front and rear ends, the U-shaped groove polishing head 72 and the U-shaped groove polishing head 73 have a threaded hole 743 at the front and rear ends, the insertion hole 741 has a fastening screw 742 inside, and one end of the fastening screw 742 is placed in the threaded hole 743 and the threaded hole 744.

[0020] A U-shaped groove polishing head 72 has a insertion groove 721 on one side of its bottom end, and an insertion strip 722 on the other side of its bottom end. The insertion strip 722 is adjacent to one side of the insertion groove 721. A U-shaped groove polishing head 73 has insertion grooves 731 on both sides of its top end, and insertion strips 732 are provided on both sides of the U-shaped groove polishing head 73. The insertion strips 732 are adjacent to one side of the insertion grooves 731.

[0021] The dimensions of the first insertion slot 721 match the dimensions of the second insertion slot 731, and the second insertion slot 731 can slide into the first insertion slot 721. The dimensions of the first insertion strip 722 match the dimensions of the second insertion strip 732, and the first insertion strip 722 can slide into the second insertion strip 732.

[0022] Working principle:

[0023] The support block 71 is equipped with U-shaped groove polishing head 1 72 and U-shaped groove polishing head 2 73 on both sides and bottom. They reciprocate within the groove of the irregular rod to achieve fine polishing of the inner wall of the groove.

[0024] The U-shaped groove polishing head 1 72 and the U-shaped groove polishing head 2 73 adopt a detachable design, which greatly improves the flexibility and convenience of operation.

[0025] The installation steps are as follows:

[0026] First, install the first locking plate 74: Place the first locking plate 74 at the rear end of the support block 71, and carefully adjust its position to ensure that the multiple evenly distributed insertion holes 741 inside the locking plate 74 are precisely aligned with the threaded holes 744 at the rear end of the support block 71. Then, select suitable fastening screws 742, pass them through the insertion holes 741 one by one, and screw them firmly into the threaded holes 744. In this way, the locking plate 74 is firmly fixed to the rear end of the support block 71.

[0027] Next, install the U-shaped groove polishing heads 72: After installing the first locking plate 74, insert the two U-shaped groove polishing heads 72 into the grooves on both sides of the support block 71. When inserting, ensure that the threaded hole 743 at the rear end of the U-shaped groove polishing head 72 is aligned with the insertion hole 741 in the first locking plate 74. After ensuring proper alignment, use the fastening screw 742 again, passing it through the insertion hole 741 and screwing it into the threaded hole 743. This will initially fix the U-shaped groove polishing heads 72 to both sides of the support block 71.

[0028] Next, assemble the U-shaped groove polishing head: precisely align the insertion slots 731 and insertion strips 732 on both sides of the top of the second U-shaped groove polishing head 73 with the insertion slots 721 and insertion strips 722 at the bottom of the first U-shaped groove polishing head 72, and then slowly insert them to complete the assembly of the first U-shaped groove polishing head 72 and the second U-shaped groove polishing head 73. Then, using the fastening screw 742, pass it through the insertion hole 741 in the first locking plate 74 and screw it into the threaded hole 743 at the rear end of the second U-shaped groove polishing head 73. At this point, not only is the connection between the first U-shaped groove polishing head 72 and the second U-shaped groove polishing head 73 achieved, but their pre-fixation is also completed.

[0029] Finally, install the second locking plate 74: Place the second locking plate 74 at the front end of the support block 71, ensuring that the insertion hole 741 is completely aligned with threaded hole one 743 and threaded hole two 744. Then, using the fastening screw 742, screw it through the insertion hole 741 into threaded hole one 743 and threaded hole two 744 respectively, firmly fixing the locking plate 74 to the front end of the support block 71. This completes the installation of the U-shaped groove polishing head one 72 and the U-shaped groove polishing head two 73.

[0030] Disassembling the U-shaped groove polishing head 72 and the U-shaped groove polishing head 73 is also very simple. First, remove the fastening screws 742 one by one, carefully remove the two locking plates 74, and then smoothly pull out the U-shaped groove polishing head 72 and the U-shaped groove polishing head 73 from both sides and the bottom of the support block 71. This completes the disassembly of the U-shaped groove polishing head 72. To replace the U-shaped groove polishing head 72 and the U-shaped groove polishing head 73, repeat the above disassembly steps.

[0031] In practical applications, if the groove depth or width of an irregularly shaped rod is large, the U-shaped groove polishing head 1 72 and U-shaped groove polishing head 2 73 of the same size can be replaced according to actual needs to ensure that the two can fit tightly to the groove of the irregularly shaped rod, thereby achieving a more ideal polishing effect on the groove.
