[0003] Before processing and polishing the product, it is necessary to use a clamping fixture to fix the product. Currently, the product clamping on the market is mainly manual chuck or pneumatic chuck clamping. Manual chuck fixation requires manual tightening or loosening of the chuck every time the material is loaded or unloaded, which is time-consuming and labor-intensive. Pneumatic chucks are limited by the gas pressure of the air source, and the clamping force of the clamped product may be insufficient, causing the product to loosen. In addition, the pneumatic chuck has a small stroke and poor versatility. Utility Model Content

[0025] See also Figure 1-4 A grinding device for product processing includes a connecting base 1, a clamping base plate 2 is arranged at the top of the connecting base 1, two side support assemblies 3 are symmetrically arranged at the top of the clamping base plate 2, a driving cylinder 4 is installed in the middle of the top of the connecting base 1, a clamping connecting rod assembly 5 is arranged between the two side support assemblies 3, and a product to be polished 6 is arranged above the clamping connecting rod assembly 5.

[0026] The side support assembly 3 includes side support plates 301 symmetrically and vertically arranged on both sides of the top of the clamping base plate 2. Two fixing through holes 302 are symmetrically opened on the side of the side support plate 301. A top groove 303 is opened on the side of the top of the side support plate 301. A supporting connecting plate 304 is set at the top of the top groove 303. The side of the supporting connecting plate 304 is connected to the top of the side support plate 301 through the set fixing bolts 305.

[0027] The clamping connecting rod assembly 5 includes an annular connecting seat 501 arranged in the middle of the top of the clamping base plate 2, the output shaft at the top of the driving cylinder 4 passes through the middle of the clamping base plate 2 and extends into the annular connecting seat 501, and a driving triangle block 507 is arranged on the output shaft at the top of the driving cylinder 4, and three side protrusions 502 are evenly arranged on the side of the top of the annular connecting seat 501.

[0028] The sides of the side protrusions 502 are each provided with a clamping push rod 503, and two side connecting plates 504 are symmetrically provided on both sides of the clamping push rod 503. The side connecting plates 504 are rotatably connected to the side protrusions 502 and the clamping push rod 503 via a rotating pin 505. A clamping fixing block 506 is provided on the inner side edge of the top end of the clamping push rod 503, and the bottom end of the clamping push rod 503 is hingedly connected to the side of the driving triangle block 507.

[0029] Embodiment 2: The difference between this embodiment and embodiment 1 is that the side of the bottom end of the side support plate 301 is triangular in shape.

[0030] The supporting strength of the side support plate 301 to the product 6 to be polished is enhanced.

[0031] Embodiment 3: The difference between this embodiment and embodiment 1 is that the inner side wall of the clamping and fixing block 506 is evenly provided with a plurality of anti-slip grooves.

[0032] The clamping fixed block 506 is driven by the clamping push rod 503 to clamp the bottom end of the product 6 to be polished more firmly.

[0033] Embodiment 4: The difference between this embodiment and embodiment 1 is that the driving triangular block 507 is in a triangular shape, and the sides of the driving triangular block 507 are hingedly connected to the bottom end of the clamping push rod 503.

[0034] The driving triangle block 507 can simultaneously pull the three clamping push rods 503, so that the top of the clamping push rod 503 can clamp and fix the bottom of the product to be polished 6.

[0035] In this embodiment, since the products currently on the market are mainly clamped by manual chucks or pneumatic chucks, manual chuck fixation requires manual tightening or loosening of the chuck every time the material is loaded or unloaded, which is time-consuming and labor-intensive. The pneumatic chuck is limited by the gas pressure of the air source, and the clamping force of the clamped product may be insufficient, causing the product to loosen. In addition, the pneumatic chuck has a small stroke and poor versatility.

[0036] In summary, in the specific implementation, when the user needs to polish the product to be polished 6, the user first needs to fix the product to be polished 6 and place the bottom end of the product to be polished 6 into the clamping connecting rod assembly 5, while the side of the product to be polished 6 is resisted by the side support plate 301 in the side support assembly 3 arranged on the clamping base plate 2, so as to keep the product to be polished 6 stable on the clamping connecting rod assembly 5, so that the bottom end of the product to be polished 6 can be placed on the driving triangle block 507.

[0037] Next, by starting the driving cylinder 4, the output shaft on the driving cylinder 4 will be pulled back, thereby driving the driving triangle block 507 set thereon to retract and pull. Since the side of the driving triangle block 507 is hingedly connected to the clamping push rod 503, and the top of the clamping push rod 503 is rotatably connected to the side protrusion 502 through the set side connecting plate 504, when the driving triangle block 507 is pulled back, the top of the clamping push rod 503 will be in a retracted state, thereby clamping and fixing the bottom end of the product 6 to be polished, ensuring that the product 6 to be polished will not shake during polishing.

[0038] And when the output force of the driving cylinder 4 is small, the user can also replace the driving cylinder 4 with a larger cylinder. Unlike the pneumatic chuck clamping method, insufficient clamping force requires replacement of a larger chuck, which is costly. The clamping link assembly 5 is connected to the driving cylinder 4, and three clamping points are arranged on the clamping link assembly 5. The opening size of the clamping link assembly 5 is controlled by the stroke of the driving cylinder 4. When the opening size is not enough to meet the product requirements, it is only necessary to replace the stroke size of the driving cylinder 4, and at the same time replace the clamping fixing block 506 to meet the matching size of the product. It has strong overall versatility, is practical and reliable.
