[0046] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0047] Example 1

[0048] like Figure 1-3 As shown, the utility model discloses a valve body grinding machine, comprising:

[0049] Base 10;

[0050] A body, disposed on the base;

[0051] A grinding device 2 is installed on the machine body. Since the grinding device is a mature prior art, it will not be described in detail in this embodiment;

[0052] The fixing device is installed on the machine body and is used to fix the valve.

[0053] The machine body of the utility model is composed of a first machine body 31 fixed on the base 10 and a second machine body 32 sliding on the base 10, the grinding device 2 and the fixing device are respectively installed on the first machine body 31 and the second machine body 32, and the first machine body 31 and the second machine body 32 can be controlled by the screw mechanism to move closer to or away from each other;

[0054] A material taking area 32a is provided on a side of the second body 32 away from the first body 31, and a sealed grinding chamber is formed when the second body 32 contacts the first body 31;

[0055] The second machine body 32 is provided with a circulating conveying device for installing a plurality of fixing devices, and the circulating conveying device can sequentially convey the fixing devices into the grinding chamber or the material taking area.

[0056] In this embodiment, the screw structure is composed of a screw 40 installed on a base, a screw seat 41 cooperating with the screw 40 , and a motor 42 driving the screw to rotate. The screw seat 41 is connected to the second body 32 .

[0057] In this embodiment, the circulating conveying device includes:

[0058] The partition plate 50 is disposed in the second body 32 and divides the second body 32 into a feeding area 32b and a taking-out area 32a;

[0059] Sprockets 51 are rotatably connected to the upper and lower sides of the partition plate 50 and can be driven by a motor (not shown, but can be installed on the side wall of the second body);

[0060] The chain 52 is transmission-connected between the sprockets 51;

[0061] The mounting plate 53 is fixed on the chain 52 and moves with the chain 52;

[0062] The fixing device is installed on the mounting plate 53 .

[0063] In this embodiment: the fixing device comprises:

[0064] The slide groove is composed of a first slide groove 61 and a second slide groove 62 which are arranged on the mounting plate 53 and are spaced apart from each other;

[0065] The telescopic groove 63 is formed on the groove wall of the first sliding groove 61 and the second sliding groove 62;

[0066] The telescopic shaft 64 moves in the telescopic slot 63, and a limit spring 65 is provided between the telescopic shaft 64 and the telescopic slot 63;

[0067] A clamping plate 66 is fixed to each telescopic shaft 64 and forms a clamping area 66a for clamping the valve;

[0068] A threaded cavity is formed on the clamping plate 66 and penetrates at both ends;

[0069] A limit bolt 67 is cooperatively disposed in the bolt cavity;

[0070] The mounting plate 53 is provided with a limiting blind hole 68 for the end of the limiting bolt 67 to enter, and the limiting blind hole 68 is arranged at the bottom of the slide groove.

[0071] In this embodiment, a groove 69 is provided on the clamping plate 66. When the valve body is clamped by the clamping plate 66, the valve port can enter the groove 69, thereby preventing the valve body from being loosened from the clamping plate.

[0072] refer to Figure 1-3 When this embodiment is in use, the worker is located on the side of the second body away from the first body, and takes and loads materials through the material taking area. When loading materials, the valve body is placed between the clamping plates and held by the clamping plates. At the same time, the end of the limiting bolt is screwed into the limiting blind hole to complete the fixation of the invention. Similarly, when taking materials, the opposite is true.

[0073] When the second body is controlled by the screw structure to contact the first body, the two form a grinding chamber. When grinding is performed in the grinding chamber, most of the waste chips generated will be controlled in the second body, thereby providing protection for the workshop environment.

[0074] Moreover, in order to ensure the grinding efficiency, the present embodiment has a circulating conveying device in the second body. When the sprocket is driven to rotate by the motor, the mounting plate (and the fixing device on the mounting plate) is controlled to enter the feeding area from the picking area. Therefore, workers can load and unload the fixing device in the picking area. The loading and unloading processes are independent of the grinding process. Therefore, there is no need to repeatedly control the movement of the second body, thereby ensuring production efficiency.

[0075] Embodiment 2 is different from Embodiment 1 in that

[0076] like Figure 4-6 As shown, in this embodiment: a collecting structure 7 is provided on the second body 32, wherein the collecting structure 7 includes:

[0077] A collection frame 70 is mounted on the second body 32;

[0078] A collection tank formed in the collection frame 70;

[0079] The transmission rollers 71 are rotatably connected to the collecting tank and are arranged at intervals and driven by a motor, which can be installed on the outer wall of the collecting frame 70;

[0080] The transmission belt 72 is connected between the transmission rollers 71;

[0081] The transmission belt 72 divides the collecting tank into a material receiving area 73a and a material discharging area 73b, and a material discharging port is provided at the bottom of the collecting tank, and a material discharging control valve 74 is provided on the material discharging port.

[0082] In this embodiment, the bottom of the collecting trough (ie, the bottom inner wall of the discharge area 73b) is gradually inclined from the edge toward the discharge port, so as to facilitate the discharge of debris through the discharge port.

[0083] refer to Figure 4-6 In this embodiment, a collection structure is provided on the second body to collect the debris generated during the grinding process and to be recycled for reuse. In more detail:

[0084] When the second body is controlled to contact with the first body, the collection frame of this embodiment is located below each grinding device to receive the debris generated during the grinding process. Moreover, this embodiment also provides a movable transmission belt in the collection frame. When the transmission belt is moving, the debris falling on the transmission belt can be brought into the discharge area to wait for discharge; and when the transmission belt stops, the material receiving work can be carried out. Therefore, when the second body is separated from the first body, it is convenient for workers to check the waste chips on the transmission belt.

[0085] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
