DETAILED DESCRIPTION

[0022] 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 in 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.

[0023] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, in the embodiment of the utility model: a gearbox housing blank sand cleaning device includes a frame 110, a hydraulic push rod 120 is installed on one side of the frame 110, and the output end of the hydraulic push rod 120 is connected to a vibration assembly 130, and a second output motor 140 is installed on the other side of the frame 110, and the output end of the second output motor 140 is connected to a clamping part 160 through a telescopic assembly 150. When the vibration assembly 130 and the second output motor 140 are started, the casting rotates around the X-axis while vibrating at a high frequency.

[0024] In specific operation, the casting is placed between the vibration assembly 130 and the clamping part 160, and then the hydraulic push rod 120 is started to push the vibration assembly 130 to the right, shortening the distance between the vibration assembly 130 and the clamping part 160, so as to clamp and fix the casting, and then the vibration assembly 130 is started, and the output end of the vibration assembly 130 drives the casting to vibrate at a high frequency, so as to loosen the dry sand in the internal pores of the casting, and complete the preliminary separation of the casting and the dry sand, and at the same time, the second output motor 140 is started, and its output end drives the clamping part 160 and the casting to rotate, and during the rotation of the casting, the loosened dry sand falls off, and the sand cleaning operation is completed.

[0025] The vibration assembly 130 includes a first output motor 131, a push block 132, a vibration block 133, a vibration rod 134, an abutment disk 135 and a first spring 136. The first output motor 131 is installed inside the vibration assembly 130, and the output end of the first output motor 131 is connected to the push block 132. A vibration rod 134 is inserted on the right side of the vibration assembly 130, and the vibration block 133 is connected to the left side of the vibration rod 134. The vibration block 133 and the push block 132 are symmetrical with point A as the center. The right end of the vibration rod 134 is rotatably connected to the abutment disk 135, and the first spring 136 is wound around the outer wall of the vibration rod 134.

[0026] The principle of the vibration assembly 130 is: start the first output motor 131, and the output end of the first output motor 131 drives the push block 132 to rotate, and the first spring 136 is in an extruded state, ensuring that the vibration block 133 can always abut against the push block 132, and the push block 132 can push the vibration block 133 to move to the right during the rotation. With the continuous rotation of the push block 132, the vibration block 133 can be driven to reciprocate left and right, that is, the vibration rod 134 and the abutment plate 135 produce reciprocating vibration left and right, thereby driving the casting to vibrate.

[0027] A ball bearing 137 is disposed inside the push block 132 , and the ball bearing 137 is attached to the vibration block 133 .

[0028] In the above, the ball 137 can prevent the push block 132 and the vibration block 133 from direct contact, change the sliding friction between the push block 132 and the vibration block 133 into rolling friction, and reduce the resistance when the push block 132 and the vibration block 133 rotate relative to each other.

[0029] A sliding groove 138 is formed on the inner wall of the vibration component 130 , and a sliding block 139 is slidably connected inside the sliding groove 138 . The side of the sliding block 139 away from the sliding groove 138 is connected to the vibration block 133 .

[0030] Through the above design, the stability of the vibration block 133 during the reciprocating movement left and right is increased.

[0031] The telescopic assembly 150 includes a sleeve 151 and a connecting block 152 . The connecting block 152 is inserted into the sleeve 151 . A sealing plate 153 is connected to the right side of the connecting block 152 . A damping hole 154 is opened in the sealing plate 153 . Hydraulic oil is injected into the sleeve 151 .

[0032] The principle of the telescopic assembly 150: when the clamping part 160 and the casting are vibrating, the connecting block 152 and the sealing plate 153 are vibrating synchronously, and the resistance created by the relative displacement between the hydraulic oil and the sealing plate 153 absorbs and offsets the vibration force of the connecting block 152, and intercepts the vibration force of the casting to avoid affecting the second output motor 140.

[0033] A second spring 155 is connected to the inner wall of the sleeve 151 , and the other end of the second spring 155 is connected to the sealing plate 153 .

[0034] Through the above design, the second spring 155 is deformed when vibrated, and the elastic force generated thereby increases the effect of intercepting the vibration force of the casting.

[0035] The clamping portion 160 includes a plate 161 and two sets of limiting ridges 162 . The two sets of limiting ridges 162 are connected to two sides of the plate 161 .

[0036] The above design ensures that the clamping portion 160 can drive the casting to rotate synchronously when rotating.

[0037] A method for sand cleaning a gearbox housing blank, the steps of which are as follows:

[0038] S1: The casting is fixed. The casting is placed between the vibration assembly 130 and the clamping part 160, and then the hydraulic push rod 120 is started. The output end of the hydraulic push rod 120 pushes the vibration assembly 130 to move, shortening the distance between the vibration assembly 130 and the clamping part 160, thereby completing the clamping and fixing of the casting;

[0039] S2: The dry sand is loosened, and the vibration component 130 is started. The output end of the vibration component 130 drives the casting to vibrate at a high frequency to loosen the dry sand in the pores of the casting;

[0040] S3: The dry sand is separated, and the second output motor 140 is started. The output end of the second output motor 140 drives the telescopic assembly 150, the clamping part 160 and the casting to rotate, so that the casting rotates while vibrating, and the loose dry sand is shaken off.

[0041] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
