Background

A grinder (Grindingmachine) is a machine tool that grinds a workpiece with a grinder to obtain a desired shape, size, and precision machined surface. In the process of machining a workpiece to be machined, the grinding machine needs to clamp the workpiece to be machined.

CN211540545U discloses a clamping device for a blade grinder, which comprises a base, wherein a worm and a rotating shaft are respectively installed in the base in a rotating way, a worm wheel is sleeved outside the rotating shaft, the worm wheel is connected with the worm in a meshed way, a cam is installed at the end part of the rotating shaft, a sliding clamping plate is slidably arranged at the top of a supporting plate, the top of the supporting plate is fixedly connected with the fixed clamping plate through a screw, a push rod is welded at one side of the sliding clamping plate, a ball is installed at the end part of the push rod, and the ball is in pressing contact with one side of the cam. The clamping device improves the processing precision of the blade, but the structure of the clamping device is relatively complex, which is not beneficial to operation; meanwhile, the clamping device cannot effectively avoid the problem that the cutter is damaged due to overlarge clamping pressure.

It is apparent that the described embodiments are only some embodiments of the present utility model, but not all embodiments, and that other embodiments obtained by those skilled in the art without inventive effort are within the scope of the present utility model based on the embodiments of the present utility model.

In the description of the present utility model, the descriptions of the terms "one embodiment," "some embodiments," "illustrative embodiments," "examples," "specific examples," or "some examples," etc., mean that a particular feature, structure, material, or characteristic described in connection with the embodiment or example is included in at least one embodiment or example of the present utility model. In this specification, schematic representations of the above terms do not necessarily refer to the same embodiments or examples. Furthermore, the particular features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples.

Specific embodiments of the present utility model are described in detail below.

Referring to fig. 1 to 2, a clamping device for a blade grinder includes a support plate 100, one side of the support plate 100 being provided with a fixed clamping plate 101;

the top of the support plate 100 is slidably provided with a sliding grip plate 102;

a push rod 105 is fixedly connected to one side of the sliding clamping plate 102;

the push rod 105 is composed of a first circular truncated cone section 1051, a cylindrical section 1052 and a second circular truncated cone section 1053 which are sequentially arranged.

Further, the cylindrical section 1052 and the second circular truncated segment 1053 are detachably connected, which facilitates the installation of the push rod 105.

Further, a sliding block 103 is arranged on the sliding clamping plate 102, and a sliding groove 104 is correspondingly arranged on the sliding block 103. A chute 104 is provided on the support plate 100 for sliding connection between the sliding clamping plate 102 and the support plate 100.

Further, the support plate 100 is provided with a fixing plate 107, and the fixing plate 107 is provided with a fixing hole.

Further, a fixing table 110 is provided on the support plate 100, and a screw hole is provided on the fixing table 110.

Further, a screw 109 is provided on the fixing table 110, and the screw 109 penetrates through the threaded hole; one end of the screw 109 is fixedly connected with a fixed block 108. By rotating the screw 109, the push rod 105 is moved, and clamping of the tool is achieved.

Further, a rubber layer is provided on the side of the fixed block 108 close to the push rod 105. The rubber layer has a certain buffer function, and can prevent the excessive acting force applied by the screw 109, thereby causing cutter damage.

Further, a spring 106 is sleeved on a part of the surface area of the push rod 105.

Further, the included angle between the generatrix of the first circular truncated cone section 1051 and the bottom surface is 1 ° to 30 °.

The larger the included angle of the first circular truncated cone section 1051, the stronger the displacement restriction effect on the push rod 105, and therefore, the included angle needs to be controlled within a certain range.

Further, the included angle between the generatrix of the first circular truncated cone section 1051 and the bottom surface is 1 ° to 20 °.

Further, the included angle between the generatrix of the first circular truncated cone section 1051 and the bottom surface is 5 ° to 10 °.

Further, the included angle between the generatrix of the second circular truncated cone section 1053 and the bottom surface is 1 ° to 30 °.

The larger the included angle of the second circular truncated cone section 1053, the stronger the displacement restriction effect on the push rod 105, and therefore, the included angle needs to be controlled within a certain range.

Further, the included angle between the generatrix of the second circular truncated cone section 1053 and the bottom surface is 1 ° to 20 °.

Further, the included angle between the generatrix of the second circular truncated cone section 1053 and the bottom surface is 5 ° to 10 °.

Further, the lower bottom surface (i.e., the side with larger bottom area) of the first circular segment 1051 is fixedly connected to the sliding clamping plate 102.

Further, the lower bottom surface (i.e., the side with the greater bottom area) of the second circular truncated segment 1053 is adjacent to the fixed surface 108.

Further, the length of the cylindrical section 1052 is greater than the thickness of the mounting plate 107.

Further, the length of the cylindrical section 1052 is less than the sum of the thickness of the fixed plate 107 and the thickness of the double tool.

Too small a length of the cylindrical section 1052 will result in the push rod 106 not being movable, and thus not being able to clamp the tool; and if the length is too large, the pre-fixing effect is lost.

Further, the diameter of the bottom surface of the cylindrical section 1052 is smaller than the diameter of the fixing hole.

Further, the ratio of the bottom diameter of the cylindrical section 1052 to the diameter of the fixing hole is 0.95 to 0.99:1.

too small a diameter of the bottom surface of the cylindrical section 1052 can cause the circular truncated cone section to lose the limiting function; and too large a diameter of the bottom surface may result in an inability to achieve effective clamping of the tool.

Further, the upper bottom surface (bottom surface is small) of the first circular truncated cone section 1051 coincides with the bottom surface of the cylindrical section 1052.

Further, the upper bottom surface (smaller bottom area) of the second circular truncated cone section 1052 coincides with the bottom surface of the cylindrical section 1052.

In summary, according to the utility model, the push rod is arranged into the first circular table section and the second circular table section, so that the limit of the push rod is realized, namely, the movement displacement of the push rod is limited within a certain range, and the movement range of the sliding clamping plate is further limited.

While the embodiments of the present utility model have been described in detail with reference to the specific embodiments, the present utility model is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present utility model within the knowledge of those skilled in the art. Furthermore, embodiments of the utility model and features of the embodiments may be combined with each other without conflict.
