Detailed Embodiments

[0030] To facilitate the understanding of the present utility model, the present utility model will be described more comprehensively below with reference to the relevant drawings. The preferred embodiments of the present utility model are shown in the drawings.

[0031] As Figures 2 to 4 shown, a sawing and positioning device 10 for casting nozzle is used to be fixed on a sawing machine, which includes a support assembly 100 and a clamping assembly 200. The support assembly 100 includes a base 110, a support seat 120 and an elastic member 130. The base 110 is arranged on the sawing machine, the support seat 120 is slidably arranged on the base 110, and the elastic member 130 is respectively abutted against the base 110 and the support seat 120. The elastic member 130 is used to push the support seat 120 so that the support seat 120 slides close to one end of the base 110. A loading groove 121 is formed on the support seat 120, and the loading groove 121 is used to receive the nozzle tree 20. The clamping assembly 200 includes two clamping members 210. Both clamping members 210 are arranged on the sawing machine, and the two clamping members 210 are respectively located on both sides of the support seat 120. The clamping member 210 includes an intermediate connecting plate 211 and a clamping plate 212. The intermediate connecting plate 211 is arranged on the sawing machine, and the clamping plate 212 is adjustably arranged on the intermediate connecting plate 211. A clamping groove 2121 distributed along the vertical direction is formed on the clamping plate 212. When the sawing machine drives the two clamping members 210 to approach each other, the inner side walls of the two clamping grooves 2121 respectively clamp both sides of the nozzle tree 20.

[0032] It should be noted that the sawing machine is used to drive the two clamping members 210 to approach each other or move away from each other. The sawing machine is an existing device, and its structure will not be described in detail here. The clamping member 210 includes an intermediate connecting plate 211 and a clamping plate 212. The intermediate connecting plate 211 is fixedly installed on the sawing machine, and the intermediate connecting plate 211 is an intermediate structure between the clamping plate 212 and the sawing machine. The clamping plate 212 is installed on the intermediate connecting plate 211 with adjustable position along the vertical direction. A clamping groove 2121 is formed on the side surface of the clamping plate 212 away from the intermediate connecting plate 211. In this way, when the sawing machine drives the two clamping members 210 to approach each other, the clamping grooves 2121 of the two clamping plates 212 approach each other to jointly clamp the nozzle tree 20. A support assembly 100 is arranged between the two clamping members 210. Specifically, the base 110 is fixedly installed between the two clamping members 210, and the support seat 120 is slidably installed on the base 110. The extension line of the sliding direction of the support seat 120 is parallel to the connection line between the two clamping members 210, that is, the support seat 120 can reciprocally slide between the two clamping members 210. The elastic member 130 is installed in the base 110, and the elastic member 130 is respectively abutted against the base 110 and the support seat 120, so that the support seat 120 is located at one end position of the base 110 in the natural state. In one embodiment, the elastic member 130 is a spring.

[0033] The working principle of the casting nozzle sawing positioning device 10 of the present application is as follows: First, place the nozzle tree 20 to be sawn in the loading groove 121 of the support 120, and then the sawing machine drives the two clamping members 210 to approach each other to clamp the nozzle tree 20 to be sawn. During the clamping process of the two clamping members 210, since the support 120 can slide relative to the base 110, the support 120 always remains at the central position between the two clamping members 210. Finally, the two clamping members 210 reliably clamp the nozzle tree 20 to be sawn. In this way, after the nozzle tree 20 to be sawn is fixed, after each casting is sawn from the nozzle tree 20, the sawing machine drives the two clamping members 210 to separate from each other, and the cut nozzle tree 20 can be removed from the support 120. In this way, by setting the clamping plate 212 to be a structure with adjustable position relative to the middle connecting plate 211, it can be used to clamp and fix nozzle trees 20 of different sizes and shapes, so as to ensure that the sawing machine can smoothly saw each casting from the nozzle tree 20.

[0034] As Figure 2 shown, in one embodiment, the sawing machine includes a loading plate 310, a fixed seat 320 and a sliding seat 330. The fixed seat 320 is arranged on the loading plate 310, the sliding seat 330 is slidably arranged on the loading plate 310, and the sliding seat 330 is aligned with the fixed seat 320. Two middle connecting plates 211 are respectively arranged on the fixed seat 320 and the sliding seat 330.

[0035] It should be noted that the fixed seat 320 is fixedly installed on the loading plate 310, and the sliding seat 330 is slidably installed on the loading plate 310. For example, the sawing machine further includes a lead screw module for driving the sliding seat 330 to slide, and the lead screw module drives the sliding seat 330 to slide to approach or move away from the fixed seat 320. Two middle connecting plates 211 are respectively installed on the fixed seat 320 and the sliding seat 330, so that the middle connecting plate 211 located on the sliding seat 330 can approach or move away from the middle connecting plate 211 located on the fixed seat 320. It should be noted that when the nozzle tree 20 to be sawn is placed in the loading groove 121 of the support 120, there is a gap between the nozzle tree 20 to be sawn and the two clamping plates 212, and the fixed seat 320 is in a fixed state relative to the loading plate 310. As the sliding seat 330 drives the connected clamping plate 212 to approach and push against the nozzle tree 20 to be sawn, the nozzle tree 20 to be sawn will push the support 120 to slide relative to the base 110 to approach the clamping plate 212 located on the fixed seat 320. In this way, it is ensured that the support 120 always remains at the central position between the two clamping plates 212, and finally the two clamping plates 212 reliably clamp and fix the nozzle tree 20 to be sawn.

[0036] As Figure 2 and Figure 4As shown, in one embodiment, the clamping plate 212 includes a plate body 2122 and two clamping blocks 2123. The plate body 2122 is adjustably disposed on the middle connecting plate 211, and the two clamping blocks 2123 are disposed on the plate body 2122 so as to form a clamping groove 2121 between the two clamping blocks 2123.

[0037] It should be noted that since the positions of castings of different models relative to the sprue tree 20 are not determined, and the sizes and shapes of the sprue tree 20 are also different, in order to enable the clamping plate 212 to reliably clamp the sprue tree 20, the clamping plate 212 is configured as a structure in which the plate body 2122 and the clamping blocks 2123 are assembled. Specifically, the plate body 2122 is detachably mounted on the middle connecting plate 211, so that the lateral position and the longitudinal position of the plate body 2122 relative to the middle connecting plate 211 are both adjustable. Further, the distance and the height position between the two clamping blocks 2123 are also adjustable, so that the width of the clamping groove 2121 formed between the two clamping blocks 2123 is adjustable, and thus different-sized and -shaped sprue trees 20 can be reliably clamped and fixed.

[0038] As Figure 4 shown, in one embodiment, a first adjustment hole 21221 is formed in the plate body 2122. The first adjustment hole 21221 is passed through with a fastener and screwed onto the middle connecting plate 211 so that the position of the plate body 2122 relative to the middle connecting plate 211 is adjustable.

[0039] Specifically, for example, the fastener is a bolt, and the first adjustment hole 21221 is a waist-shaped hole structure. In this way, the plate body 2122 is fixed to the middle connecting plate 211 by the bolt, so that the position of the plate body 2122 relative to the middle connecting plate 211 is adjustable.

[0040] As Figure 4 shown, in one embodiment, a plurality of screw holes 21222 are further formed in the plate body 2122. The screw holes 21222 are divided into two groups and are respectively located on both sides of the first adjustment hole 21221. A second adjustment hole 21231 is formed in the clamping block 2123. When the second adjustment hole 21231 is passed through with a fastener and screwed into the screw hole 21222, the position of the clamping block 2123 relative to the plate body 2122 is adjustable.

[0041] In this way, the position of the clamping block 2123 relative to the plate body 2122 is adjustable, so that the width of the clamping groove 2121 formed between the two clamping blocks 2123 is also adjustable. In one embodiment, a plurality of clamping blocks 2123 are provided, and the clamping blocks 2123 are divided into two groups and are respectively located on both sides of the first adjustment hole 21221. In this way, the two groups of clamping blocks 2123 jointly enclose the clamping groove 2121.

[0042] As Figure 2 and Figure 5As shown, in one embodiment, a chute 111 is formed in one of the base 110 and the support 120, and a slide rail 140 is provided on the other. The slide rail 140 is slidably disposed in the chute 111 so that the support 120 reciprocally slides relative to the base 110 between the two clamping members 210.

[0043] It should be noted that, for example, a chute 111 is formed on the base 110, and a slide rail 140 is provided on the support 120. The slide rail 140 is slidably disposed in the chute 111 in a matching manner. In another embodiment, a chute is formed on the support 120, and a slide rail is provided on the support 120. In this way, the support 120 can stably perform linear reciprocating sliding relative to the base 110.

[0044] In one embodiment, one side surface of the support 120 close to the fixed seat 320 abuts against the elastic member 130. In this way, under the pushing action of the elastic member 130, the support 120 has a tendency to move away from the fixed seat 320. When the sliding seat 330 drives the clamping plate 212 mounted on the sliding seat 330 to push against the water outlet tree 20 of the band saw cut, the water outlet tree 20 will push the support 120 close to the fixed seat 320, and finally the clamping plate 212 on the fixed seat 320 and the clamping plate 212 of the sliding seat 330 jointly clamp and fix the water outlet tree 20 to be sawed.

[0045] As Figure 2 and Figure 3 shown, in one embodiment, a clearance groove 122 is formed in the middle of the material loading groove 121.

[0046] It should be noted that the clearance groove 122 is used to avoid the water outlet tree 20 to ensure that the two side frame positions of the water outlet tree 20 are stably clamped and fixed in the material loading groove 121.

[0047] As Figure 2 and Figure 6 shown, in one embodiment, a clamping piece 150 is respectively provided on two opposite inner side walls of the material loading groove 121, and the two clamping pieces 150 are used to jointly clamp the water outlet tree 20.

[0048] It should be noted that in order to enable the material loading groove 121 to be used for clamping and fixing water outlet trees 20 with different thicknesses, clamping pieces 150 distributed oppositely are installed on the inner side walls of the material loading groove 121. For example, the clamping pieces 150 are installed on the inner side walls of the material loading groove 121 through fasteners. In this way, the corresponding clamping pieces 150 can be selected according to the different thicknesses of the water outlet tree 20, so as to ensure that the clamping pieces 150 reliably clamp the water outlet tree 20. In one embodiment, an inclined surface 151 is provided on the clamping piece 150. The inclined surface 151 can guide the water outlet tree 20 and enable the clamping piece 150 to have a certain elastic deformation performance, so as to reliably clamp and fix the water outlet tree 20.

[0049] The above-described embodiments merely represent several implementation manners of the present utility model. The description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. Among them, the installation / fixing / setting in the present utility model, unless otherwise specifically defined, can be understood to include but not limited to locking and fixing by using fasteners / screws and welding. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the present utility model patent shall be subject to the appended claims.
